Why I prefer perpetual/premium bonds to the platinum coin

1877 $50 Thirty-year Registered 4% Consol [link]. (A consol is a perpetual bond.)

If I had to choose one of the tricks for getting around the debt ceiling, I'd go with premium bonds/perpetual bonds over the platinum coin.

I've known about the platinum coin idea for over a decade (Here's an old blog post I wrote on it back in 2013.) But I only recently found out about the premium bond idea courtesy of Ivan the K on Twitter. (Little did I know there's a long intellectual pedigree for this idea on the blogosphere.) Related is the idea of issuing perpetual bonds, or consols, to get around the ceiling (which seems to have first been discussed at the now defunct Monetary Realism blog, by Beowulf, the person who figured out the platinum coin loophole?).

The premium/perpetual bond trick, in short, is to get around the debt ceiling by issuing new bonds either at a premium to face value (premium bonds) or with no face value at all (perpetuals). Both types of bonds get around the debt ceiling because apparently only the face value of a bond counts to the ceiling.

I prefer issuing premium and/or perpetual bonds to the platinum coin because the former options don't encumber the Fed's balance sheet. The latter does. Evading the debt ceiling with any of the proposed tricks is already a dicey proposal. Choosing as your method a trick that also handicaps the Fed only multiplies the drawbacks of the whole thing.

Encumbering the Fed's balance sheet would reduce the Fed's independence, and independence is a good thing. The Fed's job is to set a target for the national monetary unit, the dollar, which along with the mile or the pound is one of the most important components of the U.S.'s system of weights & measures. To do it's job of calibrating the dollar unit, the Fed should be protected from the day-to-day ambitions of politicians, at least more so than other government institutions.

If you recall, the platinum coin requires the President to ask the U.S. Mint to manufacture a $1 trillion coin made of platinum and then deposit it at the Fed. The Fed then instantiates $1 trillion in deposits which the government can proceed to spend.

The platinum coin trick does neuter the debt ceiling. However, in the process the Fed has issued $1 trillion more dollars than it would have otherwise. This extra issuance is in turn secured by an illiquid non-interest earning asset on its balance sheet; the platinum coin. The Fed is hobbled. For a central bank to be independent, it helps to have a consistent stream of revenue to pay for expenses. That's where interest-earning assets are key. Liquid assets are also vital, because they can be sold in a snap to market participants if necessary for monetary policy purposes. Either way, a 0%-yielding trillion dollar platinum coin doesn't make the cut.

Compare this to the alternative of issuing premium bonds or perpetuals directly to the market.

In this scenario, the Fed's balance sheet hasn't changed at all. The Fed hasn't issued an extra trillion dollars into existence. And it still holds the same portfolio of highly-liquid interest-earning assets as before. Yet the debt ceiling has been evaded.

In sum, with premium and/or perpetual bonds, you get all of the debt ceiling evasion punch with none of the decline in central bank independence. It seems to me to be clearly the better of the two options. (Unless you're not a fan of Fed independence. If you aren't, the platinum coin conveniently shoots two birds with one stone: not only does it get around the debt ceiling, but it also short-circuits the independence of the central bank.)

Are the Bank of Canada's bond purchases illegal?

Pierre Poilievre, Conservative MP for Carleton, alleges that the Bank of Canada's bond buying program contravenes the Bank's powers enunciated in the Bank of Canada Act.

Allegations that the Bank of Canada has broken the law should be taken very serious. They should not be made lightly, either. We give our public servants at the Bank of Canada a wide range of powers to enact monetary policy, but only within the bounds that we permit them.

Poilievre has been actively criticizing the Bank of Canada's pandemic response ever since Covid-19 hit in 2020. I can't say I've ever seen as much Bank of Canada-targeted criticism emanating from a single Canadian politician since Poilievre began his campaign. It breaks with a long Canadian political tradition of staying (mostly) silent on the Bank of Canada's operations.

I have mixed feelings about Poilievre's approach. Yes, it's great to have more public discussion about arcane topics like the Bank of Canada Act. On the other hand, up till now Canada has avoided most of the hyperbole and conspiracies that bedevil U.S. central banking. It would be nice if things stayed that way.

Poilievre's allegations were first aired in Parliament in June. A month later he posted them on Twitter, where I became aware of them. (They garnered over 900 retweets, which is a lot for a tweet about an arcane issue like the Bank of Canada Act!) Poilievre's claims are based on his reading of Section 18(j) of the Bank of Canada Act. Section 18(j) allows the Bank to make loans to the Federal government, but those loans should not "exceed one-third of the estimated revenue of the Government of Canada for its fiscal year."

Poilievre calculates that given 2021 government revenue estimates, this would cap Bank of Canada loans to the Federal government at $118 billion. Poilievre then points to the Bank of Canada's purchases of Government securities, which have pushed the Bank's holdings of Federal government debt above the $400 billion level. Poilievre suggests that this contravenes 18(j).

The allegations caught the attention of columnist Andrew Coyne, who takes a dig at Poilievre:

Alternatively, there’s your theory that the Bank has illegally purchased $300 billion in government bonds and no one noticed it but you.

— Andrew Coyne (@acoyne) July 20, 2021

In fairness to Poilievre, it's not unimaginable that the Bank of Canada has done something illegal and no one has noticed but him. 

Back in August 2007, after all, the Bank of Canada announced its intention to extend its purchases of certain kinds of securities. It was responding to the first signs of a nascent crisis in credit market. Unfortunately it lacked jurisdiction to purchase these instruments. Its actions were unwound by September 2007 in order to bring the Bank back in compliance with the Bank of Canada Act.

I only know this because I phoned the Bank of Canada up that August wondering what legal justification it had for its actions. Several awkward conversations later, it was apparent that a mistake had been made by bank officials.

My observations made their way into a report that December for the CD Howe Institute. From there a process to update the Bank of Act began. After discussions in Parliament (including a contribution from then-governor Mark Carney here) the eventual result was an update to the Act in the spring of 2008. Tucked into Bill C-50, changes included striking out Section 18(k) and rewriting Section 18(g).

These modifications to the Bank of Act made it permissible for the Bank of Canada to conduct the purchases it had originally set out to do in August 2007, and prepped it for the much bigger fallout to come: the September 2008 credit crisis.   

So maybe Poilievre has caught a breach of law. It's happened before. That being said, echoing Coyne (who cites economist Mike Moffatt), I'm not convinced by the meat of Poilievre's argument.

In response to Poilievre's allegations about 18(j) being broken, Bank of Canada officials would probably respond that their large-scale asset purchases are authorized under Section 18(g).

The Bank of Canada's ability to make securities purchases for monetary policy purposes is set out in Section 18(g), which replaced the much narrower 18(k) in 2008. The scope of Section 18(g) is very broad. First, it is open-ended about what instruments it allows the Bank to purchase. These securities can include bonds, stocks, commercial paper, mortgage-backed securities, and more.* Second, 18(g) doesn't say anything about the Bank's purchases needing to happen in the open market. If necessary, the Bank of Canada can buy straight from the issuer.

The bit of legalese that Poilievre points to, 18(j), only applies Bank of Canada loans to the Government, say a line of credit or some other type of credit facility. Because the Bank has limited its interaction with the government to buying securities, 18(j) hasn't been triggered. And so Poilievre's allegations are just that, allegations.

Section 18(j) was devised to prevent the Bank of Canada from financing the government and preserving the Bank's independence, as Poilievre rightly points out here. And I think that's a laudable goal.

In that spirit, it's worth considering that most (but not all) of the Bank of Canada's purchases of government bonds have occurred in the open market. That is, most of the securities in the Bank's government bond portfolio were bought only after the public had initially purchased them from the Government. So in a sense, the Bank has prudently removed itself from the initial price discovery process.  

More specifically, the Bank has purchased $362 billion in Government bonds since March 2020. Of that amount, $303 billion, or 84%, was bought in the open market. The remaining $59 billion was bought directly from the Government.

Since the pandemic broke out in March 2020, the @bankofcanada has bought $362 billion worth of Federal government bonds. Most of these have been bought in the open market, but 16% ($56 billion) were bought directly from the government at periodic bond auctions.

Even when the Bank does participate in bond auctions, it does so on a non-competitive basis. That is, the Bank pays the average of all competitive bids submitted to the auction. The competitive bids are provide by banks and other primary dealers. This practice further prevents the Bank of Canada from playing an active role in setting the government's cost of capital.

So to sum up, I think the Bank of Canada is on firm legal ground. Furthermore, I also think the spirit of 18(j), a prohibition on financing the government, remains intact.

How the Bank of Canada's balance sheet went from $118 billion to $440 billion in eight weeks

Ever since the coronavirus hit, the Bank of Canada's balance sheet has been exploding. In late February its assets measured just $118 billion. Eight weeks later the Bank of Canada has $440 billion in assets. That's a $320 billion jump!

To put this in context, I've charted out the Bank of Canada's assets going back to when it was founded in 1935. (Note: to make the distant past comparable to the present, the axis uses logarithmic scaling.)

The rate of increase in Bank of Canada assets far exceeds the 2008 credit crisis, the 1970s inflation, or World War II. Some Canadians may be wondering what is going on here. This blog post will offer a quick explanation. I will resist editorializing (you can poke me in the comments section for more colour) and limit myself to the facts.

We can break the $320 billion jump in assets into three components:

1) repos, or repurchase agreements
2) open market purchases of Federal government bonds
3) purchases of Treasury bills at government auctions.

Let's start with repos, or repurchase operations. Luckily, I don't have to go into much detail on this. A few weeks back Brian Romanchuk had a nice summary of the Bank of Canada's repos, which have been responsible for $185 billion of the $320 billion jump.

With a repo, the Bank of Canada temporarily purchases securities from primary dealers, and the dealers get dollars. This repo counts as one of the Bank of Canada's assets. Some time passes and the transaction is unwound. The Bank gets its dollars back while the dealers get their securities returned. The asset disappears from the Bank of Canada's balance sheet.

The idea behind repos is to provide temporary liquidity to banks and other financial institutions while protecting the Bank of Canada's financial health by taking in a suitable amount of collateral. If the repo counterparty fails, at least the Bank of Canada can seize the collateral that was left on deposit. This is the same principle that pawn shops use. The reasons for providing liquidity to banks and other financial institutions is complex, but it goes back to the lender of last resort function of centralized banking. This is a role that central banks and clearinghouses inherited back in the 1800s.

How temporary are repos? And what sort of collateral does the Bank of Canada accept? In normal times, repos are often  unwound the very next day. The Bank also offers "term repos". These typically have a duration of 1 or 3-months. The list of repo collateral during normal times is fairly limited. The Bank of Canada will only accept Federal or provincial debt. That's the safest of the safe.

But in emergencies, the Bank of Canada is allowed to extend the time span of its repos to as long as it wants. It can also expand its list of accepted collateral to include riskier stuff. Which is what it did in March 2020 as it gradually widened the types of securities it would accept to include all of the following:

Source: Bank of Canada

That's a lot of security types! (The list is much larger if you click through the above link to securities eligible for the standing liquidity facility, see here. Nope, equities are not accepted as collateral.)

As for the temporary nature of these repos, many now extend as far as two years into the future. See screenshot below:

Source: Bank of Canada

(Note that the Bank of Canada has a very specific procedure for moving from "regular" purchases to "emergency" purchases. Part of this was implemented due to its initial reaction in 2007 to the emerging credit crisis. It accidentally began to accept some types of repo collateral that were specifically prohibited by the Bank of Canada Act. The legislative changes implemented in 2008 remedied some of the problems highlighted by this episode and codified the process for going to emergency status. Yours truly was involved in this, click through the above link.)

Anyways, we've dealt with the $185 billion in repos. Now let's get into the second component of the big $320 billion jump: open market purchases of long-term government bonds, or what the Bank of Canada refers to as the Government of Canada Bond Purchase Program (GBPP). This accounts for another $50 billion or so in new assets.

Whereas a repo is temporary, an outright purchase is permanent. Some commentators have described the purchases that the GBPP is doing as "quantitative easing". But the Bank of Canada has been reticent to call it that. When it first announced the GBPP, it said that the goal was to "help address strains in the Government of Canada debt market and enhance the effectiveness of all other actions taken so far."

This is a non-standard reason. Large scale asset purchases are normally described by central bankers as an alternative tool for stimulating aggregate demand. Usually central banks use interest rate cuts to get spending going. But when interest rates are near 0% they may switch to large scale asset purchases. (The most famous of these episodes were the Federal Reserve's QE1, QE2, and QE3). But the Bank of Canada seems to be saying that its large scale purchases are meant to fix "strains" in the market for buying and selling government bonds, not to stoke the broader economy. 

Together, the GBPP and repos account for $235 billion of the $320 billion jump.

Let's deal with the last component. Another $65 or so billion in new Bank of Canada assets is comprised of purchases of government Treasury bills (T-bills). A T-bill is a short term government debt instrument, usually no more than one year. This is interesting, because here the Bank of Canada can do something a lot of central banks can't.

Most central banks can only buy up government debt in the secondary market. That is, they can only purchase government bonds or T-bills that other investors have already purchased at government auctions. The Bank of Canada doesn't face this limit. It can buy as much government bonds and T-bills as it wants in the primary market (i.e. at government securities auctions).

Since the coronavirus crisis began, the Federal government under Justin Trudeau has revved up the amount of Treasury bills that it is issuing. As the chart below illustrates, in the last two Treasury bill auctions (which now occur weekly instead of every two weeks) it has raised $35 billion each.

For its part, the Bank of Canada bought up a massive $14 billion at each of these auctions. That's 40% of the total auction. In times past, the Bank of Canada typically only bought up around 15-20% of each auction. This 15-20% allotment was typically enough to replace the T-bills that the Bank already owned and were maturing.

By moving up to a 40% allotment at each Treasury bill auction, the Bank of Canada's rate of purchases far exceeds the rate at which its existing portfolio of T-bills matures. And that's why we're seeing a huge jump in the Bank of Canada's T-bill holdings.

(So who cares whether the Bank of Canada buys government bonds/T-bills directly at government securities auctions instead of in the secondary market, as it is doing with the GBPP?  It's complicated, but part of this controversy has to do with potential threats to the independence of the central bank. But as I said at the outset, I'm resisting editorializing.)

These three components get us to $300 billion. The last $25 billion is due to other programs. I will list them below and perhaps another blogger can take these up, or I will do so in the comments section or in another blog post:

+$5 billion in Canada Mortgage Bonds
+$5 billion in purchases via the Provincial Money Market Purchase Program (PMMP)
+$1 billion in Provincial bonds
+$8 billion in bankers' acceptances via the Bankers' Acceptance Purchase Facility (BAPF)
+$2 billion in commercial paper
+$1 billion in advances

And that, folks, is how the Bank of Canada's assets grew to $440 billion in just two months.

Should governments finance themselves through their central bank?

In places like the U.S. and Europe, it is actually difficult—if not impossible—for a government to have its central bank pay for government programs. All government spending must be financed by issuing bonds to the public or collecting taxes.

Canada, my home country, is an interesting counter-example. The financial relationship between the Federal government and the Bank of Canada—our central bank—is fairly permeable. The government has the authority to ask the Bank of Canada to directly fund a portion of its spending.

This avenue is rarely taken, however. Justin Trudeau, our current Prime Minister, currently uses bonds and taxes to fund almost all of the Federal government's spending. Just one small and unknown government program is directly funded by the Bank of Canada: the prudential liquidity management plan, an old Stephen Harper-era program. (I wrote about it here and here). The goal of the prudential liquidity plan is to provide a cash cushion that the Federal government can rely on to “safeguard its ability to meet payment obligations in situations where normal access to funding markets may be disrupted or delayed.”

The details of the program aren't really that important. The point I want to make is that the Federal government hasn't had to issue bonds to the public in order to fund the prudential liquidity management plan, nor has it had to wait for taxes to be paid. All it did was tell the Bank of Canada to create some dollars for it out of nothing, and the Bank of Canada shrugged and complied.

So would it make sense for Justin Trudeau to have the Bank of Canada fund other programs than just the prudential liquidity management plan? Why not get it to fund the Federal government's share of health spending, or national defence, or Old Age Security?

Let's take the example of national defence. Say that the Trudeau government has been planning to follow conventional funding procedure and intends to issue $400 million in new treasury bills to pay the salaries of our soldiers for the months of April and May. But Trudeau changes his mind and tasks the Bank of Canada to create $400 million in fresh deposits for the government, ex nihilo. As the soldiers' salaries come due, the dollars will be wired to the commercial banks where the soldiers do their banking, these banks in turn crediting the soldiers' accounts.

Are there any real differences between the two funding scenarios? Under both the treasury bill and Bank of Canada routes, the soldiers will get paid. What about cost savings? The Bank of Canada is obligated to pay interest to banks on the $400 million in new balances it has created. It pays a rate of 1.75% or so, which is pretty much equivalent to what the government would have paid on $400 million in new treasury bills.

Thus, from a cost savings perspective there's really no difference between the two scenarios. Either way, the government is going to be paying 1.75% in interest to whomever happens to be holding the instruments it has issued.

So my initial reaction is: meh, who cares which way Trudeau funds soldiers' salaries.

----------------

There is one asymmetry that might worry me as a citizen. Treasury bills are a useful instrument for individuals and businesses (like insurers) because they are quite safe. Bank of Canada deposits are likewise very safe, but whereas anyone can buy a treasury bill, deposits are exclusive. Only commercial banks can keep an account at the central bank. So if our soldiers are to be paid $400 million by the Bank of Canada, the supply of treasury bills will contract by $400 million leaving folks like me with fewer options for investing.

But there's an easy way to fix this shortage. Introduce central bank accounts for all. In short, allow non-banks like insurers and individuals to keep accounts at the Bank of Canada. A similar fix would be to provide a means for commercial banks to establish 100%-reserve pass-through accounts. Life insurers and individuals who open a pass-through accounts at a bank would be assured that these accounts are 100% backed by Bank of Canada deposits, the interest flowing straight from the Bank of Canada to the account holder. These accounts would function just like treasury bills.

----------------

There is one other potential asymmetry. It has to do with the unit-of-account function of money.

Like the metre, kilogram, or minute, the dollar is a key element of Canada's system of weights and measures. The dollar is by far the most complex of these standardized measurements. Unlike metres, kilograms, or minutes, Canadian prices are measured in terms of a set of items—banknotes and Bank of Canada deposits—that are constantly fluctuating in value. By carefully regulating these items, the Bank of Canada tries to keep the pricing standard as stable as possible.

Treasury bills have no role to play in the pricing standard. If a car has a sticker price of $10,000, this indicates ten thousand one-dollar banknotes, or a thousand ten-dollar banknotes. The "$10,000" indicated on the sticker is not represented by a given quantity of treasury bills.

This has important implications. If all Canadians simultaneously decide that they want to reduce the quantity of Bank of Canada notes and deposits that they hold, then every price in the Canadian economy will have to rise. After all, these instruments are the standard media that people use for describing prices. But if all Canadians decide they want to hold fewer treasury bills, goods and services prices needn't adjust—treasury bills aren't the media that Canadians use to describe the dollar. Only the price of treasury bills will have to adjust.  

So if Trudeau decides to use Bank of Canada deposits for financing, he is involving himself with the standard itself. Every price in the Canadian economy may have to adjust to his actions. But if Trudeau relies solely on treasury bills/bonds for financing, he avoids implicating himself in Canada's pricing standard, and so his influence will be much more muted. It would be better if Trudeau's political ambitions couldn't entangle Canada's system of weights and measures... more on this later.

----------------

It may be useful to work through an example in which Trudeau decides to use the Bank of Canada for a large percentage of government spending. Say that Justin is fighting for his political survival, so he comes up with a bright idea. Let's increase the number of Canadian provinces by occupying Burkina Faso. That way Canadians will have a warm place to go in the winter. Trudeau promises voters that he will carry out the invasion without burdening Canadians with new taxes. That very month he tells the Bank of Canada to start creating billions in new deposits and quickly spends them on military equipment.

At some point the recipients of these new deposits (anyone with a Bank of Canada account) will suffer deposit bloat. They will try to get rid of their excess, and as they do so prices across the Canadian economy will start to rise.

In order to preserve the standard unit, the Bank of Canada has a useful tool for halting this incipient inflation. It can increase the interest rate it pays on reserves. A higher reward will coax those who would otherwise have spent their unwanted Bank of Canada deposits into keeping them on ice. And this should alleviate the pressure on prices.

But what happens if Trudeau keeps on spending? His next idea is to send a fully-manned space mission to Pluto without raising taxes or issuing treasury bills to fund the mission. He tells the Bank of Canada to create $50 billion and immediately starts to spend it on building a rocket.

The Bank of Canada can of course raise rates again. But if you think about it, the Bank of Canada gets the money to pay higher interest by issuing more brand new dollar deposits. If the underlying cause of the inflation is Trudeau bringing too much money into existence, issuing even more of the stuff as an inducement to hold what has already been created doesn't seem like a long-term solution. At some point, the Bank of Canada will have to attack the root of the problem--the bloat of deposits itself--by reducing the supply.

There are a couple of ways to reduce the supply of deposits. The first would be to "sterilize" Trudeau's spending. The Bank of Canada can try and coax depositors to lock their funds into central bank term deposits rather than keeping them in their regular Bank of Canada accounts. Transferring the funds to a term deposit renders them non-spendable and removes the bloat, at least temporarily.

But Trudeau keeps on spending new Bank of Canada deposits, this time on the construction of a 5-metre high border wall between Canada and U.S. The Bank of Canada will have to convince an ever-growing crowd of deposit owners into locking away their funds. At some point the demand for term deposits will be saturated, and the Bank of Canada will have to increase the carrot they provide by raising term deposit rates. Additional deposits will have to be created to generate this reward. But as before, fixing an excess of deposits with more new ones only kicks the can down the road.

The Bank of Canada has a permanent way of removing the deposit bloat: it can buy deposits back and cancel them. But to do this, it needs to have some real assets sitting in its vaults. Gold, property, mortgage-backed securities, bonds, etc. Because Trudeau has been spending deposits into the economy willy-nilly, the Bank of Canada simply doesn't have assets to carry out a buy-back.

Which leaves the Bank of Canada with one last option for removing supply. Rather than repurchasing deposits, it can just destroy them outright. By declaring that x% of all deposits that have been issued will simply cease to exist, it can remove the bloat once and for all. Thus ends the inflation.

But the Bank of Canada doesn't have the power to annihilate depositors' funds. This would basically constitute a tax, and democracies don't generally give central bankers the power to tax (understandably so). Which means that only Trudeau can carry this operation out on behalf of the Bank of Canada.

To do so, he will have to levy a new tax and then destroy the proceeds. (He can't re-spend the deposits, this would only recreate the problem). Once destroyed, the deposit bloat has been remedied. But if Trudeau is determined to follow through on his vote gathering strategy of spending on programs without raising taxes, then he won't see much to be gained in carrying out the annihilation. So the inflation will continue.

----------------

I think that all of these threads can be brought together to provide an argument for why we don't want Trudeau to rely too much on the Bank of Canada for funding.

Low and consistent inflation is valuable to Canadians. Just as our measures of time, volume, and weight stay consistent (the metre doesn't get longer or shorter from one year to the next), the dollar unit should be reliable. If we all have a pretty good idea where average prices will be down the road, we can better coordinate our long-term plans. Price stability is also the fairest way to ensure neither debtors nor creditors benefit at the other's expense.

The Bank of Canada has all the tools to provide this service to the public, save one. In the extreme event that the Prime Minister decides to resort to the Bank of Canada for financing of a bunch of novel government services, and the inflation target is exceeded, the Bank of Canada can't salvage things by resorting to the definitive response: annihilating deposits. Instead it must rely on Trudeau to destroy deposits on its behalf via a tax. If the Prime Minister refuses to do this, then the reliability of the unit of account is effectively sacrificed.

Were Trudeau to rely on treasury bills and bonds rather than central bank financing to invade Burkina Faso, send a rocket to Pluto, and build a border wall with the U.S., then the Bank of Canada would never have to ask the Prime Minister to annihilate deposits in order to hit its inflation target. And so the dependability of the unit of account would be assured. Instead of every price in the economy having to adjust to Trudeau's new programs, only the market price of treasury bills and bonds would have to bear the burden of adjustment.

So should governments finance themselves through their central bank? In general, it's probably harmless. For instance, it makes no difference whether the prudential liquidity plan is financed by the Bank of Canada, the taxpayer, or government-issued treasury bills.

But in a scenario where the government is being wildly imprudent, a degree of separation between the Prime Minister and the Bank of Canada is advisable. Imagine if the whims of Canada's politicians could cause metre sticks all over Canada to grow or shrunk a bit each year. That would make for a confusing system of weights and measures, wouldn’t it? The dollar is one of Canada's most important weights & measures. It too deserves to be immunized from the political process.

Electronic money will only save central banks from subjugation if it is anonymous

50 SEK banknote issued by the Riksbank in 1960

"Do we need an eKrona?" asks Stefan Ingves, the Governor of the Riksbank, Sweden's central bank. The Riksbank is probably the central bank that has advanced the furthest in discussions surrounding the introduction of a central bank-issued digital currency (CBDC)—a new form of risk-free digital money for use by the public. Canada, New Zealand, Australia, the ECB, and China are also dissecting the idea, with more central banks to come in 2018.

Sweden is approaching the issue from a unique angle, says Ingves. It is the only country in the world showing a consistent decline in cash and coin usage. I've written about this interesting pattern here, here, and here. Below is a chart:

Ingves floats two theories. Either the Swedish public no longer wants central bank money, or alternatively they do want central bank money but not the type that is "made of pieces of paper," preferring instead an as-yet non-existent digital alternative. If so, then it may be the Riksbank's duty to provide that alternative, says Ingves.

Duty is an admirable motivation, but let me propose another reason for why the Riksbank is exploring the idea of an eKrona—self preservation. I think Sweden's central bank is terrified that it will become powerless in the future. It is desperately casting around for solutions to resuscitate itself, one of these being an eKrona. This fear is rooted in the fact that declining cash usage has led to a collapse in the resources that the Riksbank believes that it needs to function.

These worries about powerlessness are shared by central bankers around the world, many of whom expect advances in private payments technology to lead them to the same cash-light world that Sweden is currently entering. Their respective degrees of discomfort probably depend on how advanced their citizens are in the process of shifting away from cash. The Federal Reserve, which issues the world-renown $100 bill, is perhaps the farthest from having to worry, whereas central banks like the Norges Bank and Central Bank of Iceland are much closer to approaching peak cash.

What do I mean by a collapse in resources? Central banks have always been unique among government agencies for their self-sufficiency. Rather than depending on tax revenues to pay for their operations, they are capable of funding themselves internally. Central bankers like Ingves have even made a habit of providing their masters in government with a juicy dividend each year.

The magic behind this ability to self-fund is due to the central bank's monopoly on banknotes. Banknotes get into circulation when a central banker buys an asset, usually a government bond. Because the central bank doesn't have to pay any interest on the banknotes whereas the bonds it holds yield 4% or so, it gets to collects the entire 4% margin for itself as revenue. Out of those revenues it pays its expenses, the remaining profit flowing back to the government as a dividend. 

These dependable and juicy margins, otherwise known as seigniorage, have afforded central bankers a number of luxuries. First, consider the creature comforts. These include large research departments, well-paid staff, good benefits, high status, nice new office buildings, museums with free admission, and plenty of international travel and conferences.

But seigniorage also serves a more important function; as fuck you money. Fuck you money (pardon the expletive, but its such a great phrase) can be thought of as any resource base that is large enough to allow an individual or institution to reject traditional hierarchies (i.e. one's boss) without fearing the consequences. The central bank's seigniorage—its fuck you money—finances a dividend that flows to the government, effectively buying central bankers a uniquely-large degree of autonomy from the vagaries of their political masters. This safe space allows folks like Ingves to pursue their most important task in peace, namely jigging the interest rate up and down in order to set the price level. A government department that must pass around the hat each year in order to get funding would never be able to attain the same degree of independence.

At this point you may be able to see the Riksbank's problem. As the supply of krona banknotes in circulation withers, the Riksbank's seigniorage is getting smaller and smaller. This threatens not only the creature comforts that Swedish central bankers have gotten used to, but also the flows of fuck you money necessary to secure their sacred independence. If the popularity of kronor banknotes continues to drop, the perceived risks of political subjugation of the central banking machine will only grow.  

Let's take a look at some numbers. Below is a chart of Riksbank seigniorage going back to 2008.

The Riksbank calculates this number by taking the total earnings from its assets (both income and capital gains) and allocating an appropriate portion of this to the banknote component of its liabilities. The total costs of managing the bank note and coin system (printing, handling, salaries, designing etc) are deducted from this amount, leaving banknote seigniorage as the remainder.

Whereas Riksbank seigniorage clocked in at around SEK 5 billion in the late 2000s, it has plunged to SEK 560 million in 2016. If the rate of decline in banknote usage continues, my calculations show that seigniorage could fall to half that amount by 2018 and go into negative territory at some point in the early 2020s.

Falling global nominal interest rates are one important explanation for the decline in Riksbank seigniorage. As I said earlier, central bankers garner the margin between the supply of 0%-yielding banknotes in circulation and the interest payments they earn on bonds. If bond rates are declining, the margin shrinks and seigniorage suffers. But even if Swedish interest rates were to slowly recover over the next few years, this wouldn't halt the deterioration in Riksbank seigniorage. The constantly eroding base of banknotes on which the Riksbank relies for its profits would more-than-cancel out the effects of higher rates.

To shore up its flow of fuck you money, the Riksbank needs to find other sources of income. Which may be the true reason for Ingves's recent broaching of the idea of an eKrona. Given that a decline in banknotes in circulation is at the heart of the Riksbank's flagging seigniorage, then perhaps the development of a new 0%-yielding product will allow the Riksbank to rebuild its once plentiful resources.

In terms of design, one option the Riksbank is putting forward is to allow Swedes to keep accounts directly at the central bank. It refers to this option as register-based eKrona. I'm afraid that register-based eKrona is destined to be a dud. Private banks have decades worth of experience in providing accounts to the public. A central bank account will always be a poor competitor. Former New Zealand central banker Michael Reddell recently blogged on the topic of an eNZD, recalling the days when his employer offered accounts to employees:

Central banks almost inevitably would lag behind commercial banks in their technology anyway, which wouldn’t make a central bank transactions account product particularly attractive... Frankly, I’d be a bit surprised if there was much (normal times) demand at all (and I think back to the days –  decades ago –  when the Reserve Bank offered –  in direct competition with the private banks –  cheque accounts to its own staff; perhaps some people used theirs extensively,  but I used it hardly at all).

As for the supposed superior credit risk of a central bank account, I just don't see it. Sweden already insures private bank accounts for up to 950,000 kronor ($112,500) and even up to 5 million kronor in special circumstances. A central bank account could only be the superior alternative for amounts north of $112,500, but how many members of the public really keep that much in deposits?

Types of eKrona compared to cash and bank account money (source)

Given that register-based eKrona would fail miserably in securing the Riksbank a new stream of fuck-you money, Ingves and his research staff should probably be focusing entirely on the alternative form for eKrona: electronic banknotes. The Riksbank refers to this option as value-based eKrona. Unlike register-based eKrona, a value-based eKrona would possess a very special feature; anonymity. Like physical banknotes, they would be untraceable, only they would be superior to their physical forbears since they would be transferable not only face-to-face but also over the internet. The Swedish public's desire for online economic privacy would be sufficient to generate a positive demand for eKrona—after all, it is the lone product providing said services—thus restoring at least some part of the Riksbank's lost seigniorage.

In his recent speech, Ingves seems tepid on the idea of privacy for the eKrona, blithely writing that "perhaps it could contain some element of anonymity." Here's a message for him (and all those other central bankers who will eventually be in Ingves's position). "Perhaps" isn't good enough. Without a differentiating feature like anonymity, eKrona will never gain any acceptance among a public that already has decent private bank digital money. And so the Riksbank will only continue on its path to losing its wellspring of fuck you money and the independence it buys. Anonymous digital money or bust.

Who signs a country's banknotes?

2010 Bank of England note signed by Andrew Bailey, former Chief Cashier of the Bank.

A few years ago, Peter Stella and Åke Lönnberg conducted a study that classified national banknotes by the signatories on that note's face. They found some interesting results. Of the world's 177 banknotes with signatures (10 had no signature whatsoever), the majority (119) were signed by central bank officials only. Just four countries issue notes upon which the sole signature was that of an official in the finance ministry: Singapore, Bhutan, Samoa, and (drum roll) the United States.

Stella and Lönnberg hypothesize that the signature(s) on a banknote indicate the degree to which the issuing central bank's is financially integrated with its government. The lack of a signature from a nation's finance ministry might be a symbol of a more independent relationship between the two, the central bank's balance sheet being somewhat hived off from the government's balance sheet and vice versa. The presence of a finance minister's signature would indicate the reverse, that both the treasury and central bank's balance sheets might be best thought of as one amalgamated entity.

The nature of this arrangement is significant because if something disastrous were to happen to an independent central bank's financial health, say its assets were destroyed and all hope of profits dashed for eternity, the central banker should not necessarily expect support from his/her government. Lacking in resources, monetary policy could go off the rails. (Why would it go off the rails? Here I go into more detail).

On the other hand, should it be established by law that a government is to backstop its central bank, that same disaster would pose a smaller threat to monetary policy since the nation's finance minister, his John Hancock affixed to the nation's notes, would presumably come to the central bank's rescue.

These ideas are similar to Chris Sims's classification of type F and type E central banks (alternative link). One of the features of type F banks (like the Fed) is that "there is no doubt that potential central bank balance sheet problems are nothing more than a type of fiscal liability for the treasury." On the other hand, with type E banks (like the ECB) "it is not obvious that a treasury would automatically see central bank balance sheet problems as its own liability."

So is it the case that the Federal Reserve is actually more fused with the U.S. Treasury than other central banks are? One reading of the Federal Reserve Act might indicate yes. Section 16.1 stipulates that Federal Reserve notes are ultimately obligations of the US government:

Federal reserve notes, to be issued at the discretion of the Board of Governors of the Federal Reserve System for the purpose of making advances to Federal reserve banks through the Federal reserve agents as hereinafter set forth and for no other purpose, are hereby authorized. The said notes shall be obligations of the United States and shall be receivable by all national and member banks and Federal reserve banks and for all taxes, customs, and other public dues.

The language in the above phrase would seem to indicate that should the Fed find itself incapable of exercising monetary policy (Stella and Lönnberg  use the term policy insolvency), the US government is obliged to step in and make good on the Fed's promises, however those promises might be construed. The fact that Treasury Secretary Jacob Lew's signature appears on all paper notes, as does that of U.S. Treasurer Rosa Gumataotao Rios, can perhaps be taken as an indication of this guarantee.

Bank of Canada notes, on the other hand, are signed by the Governor of the BoC and his deputy. Finance Minister Flaherty's signature is nowhere in sight. This jives well with a quick reading of the Bank of Canada Act, which stipulates that though notes are a first claim on the assets of the Bank of Canada, the government itself accepts no ultimate obligation to make good on banknotes. In theory, should the Bank of Canada cease to earn a profit from now to eternity, Canadian monetary policy could go haywire—American monetary policy, backstopped by the Treasury, less so.

Other central banks go even further in formalizing this separation. In Lithuania, for instance, the law states that: "The State of Lithuania shall not be liable for the obligations of the Bank of Lithuania, and the Bank of Lithuania shall not be liable for the obligations of the State of Lithuania." Should Leituvos Bankas hit a rough patch, so will its monetary policy.

Stella and Lönnberg correlate the rise of independent central banking with a movement away from the printing of finance minister signatures on notes. For instance, the sole signature on Euro banknotes is that of the President of the ECB, Mario Draghi. Two of the currencies replaced by the Euro, the Irish punt and the Luxembourg franc, which had carried signatures of finance department officials, no longer exist, symbolic evidence of the Euro project's dedication to central bank independence.

Sims uses the ECB as an exemplar of type E central banks because "the very fact that there is a host of fiscal authorities that would have to coordinate in order to provide backup were the ECB to develop balance sheet problems suggests that such backup is at least more uncertain than in the US." For evidence, he points to the fact that the Fed carries just 1.9% of its balance sheet in capital and reserves while the ECB holds 6.7%.

Stella and Lönnberg hint at the prevalence of a "rather singular U.S. view of central bank and treasury relations." My interpretation of this is that most conversations about central banking are inherently conversations about the the world's dominant monetary superpower, the Federal Reserve. This is surely evident in the blogosphere, where we mostly talk as-if we were Bernanke, not Carney or Poloz or Ingves (Lars Christensen is a rare counter-example who is fluent in multiple "languages"). In the same way that all Americans only understand English while all foreigners are conversant in English and their native tongue, non-American commentators like me can't talk solely in terms of our own central bank (in my case the Bank of Canada) lest we fall out of the conversation. The Fed becomes our focal point.

Yet among central banks, the Fed is an odd duck, since the wording in the Federal Reserve Act and the signature on its notes would indicate a more well-integrated financial relationship between central bank and treasury than most. The upshot is that popular conceptions of the central banking nexus will often be wrong as they will be couched in terms of the U.S.'s integrated viewpoint, whereas most of the world's central banks are not structured in the same way as the U.S. A deterioration of the Fed's balance sheet would likely be neutral with respect to monetary policy, but for many of the world's nations this simply isn't the case.

On a totally unrelated side note, I found it interesting that Bank of England notes stand out as being signed by the Chief cashier of the Bank, not the governor. When the BoE opened its doors for business in 1694, the banknotes it issued were written on blank sheets of paper, often for unusual quantities (standardized round numbers were not introduced till the 1700s). The bank's directors and its governor, usually well-established bankers who simultaneously ran their family business, were not responsible for the BoE's day-to-day operations, this being devolved to the bank's cashiers who were given the repetitive task of signing each note by hand. Even when the ability to print signatures directly on to notes was developed in the 1800s, the practice of affixing the cashier's signature continued, despite the fact that mechanical process would make it easy for the higher-ranked governor to get his name on each note.

So while Mark Carney's route from the BoC to the BoE got him a higher salary, more prestige, and posher digs, in one respect his standing has deteriorated: there are no longer millions of bits of paper circulating with his name on them. Chief cashier Chris Salmon has that distinction.

From intimate to distant: the relationship between Her Majesty's Treasury and the Bank of England

James Gillray, a popular caricaturist, drew the above cartoon in 1797. In it, England's Prime Minister William Pitt the Younger is fishing through the pockets of the Old Lady on Threadneedle Street -- the Bank of England -- for gold. At the time, England was in the middle of fighting the Napoleonic wars and its bills were piling up.

According to its original 1694 charter, the Bank of England was prohibited from lending directly to the Treasury without the express authority of Parliament. Over the years, the Bank had adopted a compromise of sorts in which it provided the government with limited advances without Parliamentary approval, as long as those amounts did not exceed £50,000. In 1793 Pitt had this prohibition removed and in formalizing the Bank's lending policies, imposed no limit on the amounts that could be advanced by the Bank.

Thenceforth Pitt made large and continuous appeals to the Bank for loans. Without the traditional Parliamentary check, there was little the Bank could do except satisfy Pitt's demands. As Pitt liberally spent these borrowed funds in Europe, gold began to flow out of England in earnest, a pattern that was compounded by an internal gold drain set off when a small French force invaded Ireland in early February 1797, causing a crisis of confidence in banks. Pitt suspended convertibility of Bank of England notes into gold on February 26. England would not go back onto the gold standard until 1821, some twenty-four years after Pitt had taken it off.

Having removed both Parliament and the gold standard as checks, Pitt had effectively turned the Bank of England into the government's piggy bank. Thus the inspiration for Gillray's caricature of a groping William Pitt. To some extent, Gillray's worries were borne out as a steady inflation began after 1797. However, the Pound's inflation over that period came far short of the terrible assignat hyperinflation that had plagued France only a few years before. The fears so aptly captured in Gillray's caricature were never fully realized.[1]

Back to the future: Ways and Means advances

Pitt's robbing of the old Lady on Threadneedle street illustrates an episode in which the traditional English divide between Bank and State was removed. Both the Treasury and the Bank of England were effectively consolidated into one entity with the Treasury calling the shots.

The last decade or two illustrate the opposite -- the re-erection of walls between Bank and State. If you browse the asset side of the Bank of England's balance sheet, for instance, you'll notice an entry called Ways and Means advances to HM Treasury ("Her Majesty's Treasury"). Ways and means advances are direct loans to the government. They are generally short term, designed to provide the government with temporary financing to plug gaps between expected tax receipts.

Ways and means advances provide the government with an extra degree of freedom because they offer an alternative avenue for funding. Rather than relying on the bond market or the taxpayer for loans, the government can tap its central bank for money. Ways and means advances are very much like banking overdraft facilities. Unlike a regular loan, the borrower needn't provide a detailed account of what the overdraft will be spent on, nor do overdrafts require specific collateral. They are provided automatically and without fuss.

While overdrafts typically come with specified limits and must be paid back on schedule, they don't always turn out that way. William Pitt's machinations secured for himself what was effectively an unlimited overdraft facility to fund the war against Napoleon. A chunk of the British government's WWI expenses were funded by Bank of England Ways and Means advances and though supposedly of a short term nature, these advances took years to pay down. [2]

While any sovereign would welcome the opportunity to directly borrow from a central bank, from the perspective of the lending bank, overdrafts are risky. First, they are illiquid. Other central banking operations, say open market operations, bring a marketable asset onto the central bank's balance sheet, giving the bank the flexibility to rid itself of that asset whenever it sees fit. Secondly, overdrafts are uncollateralized. Should the borrower go bankrupt, the central bank lacks a counterbalancing asset to compensate itself for its loss.

While the Ways and Means overdraft amount to a piddling £370 million, or 0.1% of the Bank's portfolio of assets, in times past it was very large. See the chart below, cribbed from this Bank of England publication.

At various points in the late 1990s, The Bank's Ways and Means overdrafts amounted to as much as £20 billion. Given the fact that the Bank's note issue then stood at around £25 to £30 billion, Ways and Means advances provided as much as 80% of the backing for paper pounds! Insofar as the value of currency is set by the assets that back the issue, the purchasing power of the pound during the 1990s depended very much on the quality of these Ways and Means advances.

Why did Ways and Means advances contract?

In 1997, the government decided that it would cease using the Bank of England as its source for short term financing and instead would turn to money markets. The final changeover occurred in 2000, at which point the Ways and Means balance was fixed at £13.4 billion, and eventually paid down to £370 million in 2008. Thus ended the Treasury's ability to turn to the Bank of England for financing. As for the Bank, it had earned for itself a larger degree of flexibility -- a large and illiquid asset no longer existed on its balance sheet.

There seem to be a few reasons for ending Ways and Means advances. To begin with, the Treasury was already in the process of handing over its control of monetary policy to the Bank of England. Prior to 1998, the Treasury had been responsible for setting rates. Subsequent to 1998, the Bank of England's Monetary Policy Committee has set rates. The decision to freeze and eventually pay down Ways and Means advances went hand in hand with the Bank's increased independence in setting monetary policy.

Secondly, the third stage of European and Monetary Union (EMU) requires that all member nations cease to lend directly to their government. While the United Kingdom is a signatory to EMU, it never proceeded to the third stage, so it was not required to end Ways and Means advances. Nevertheless, given the possibility that it might proceed to the third stage at some future point in time, it probably made sense to plan ahead by ensuring that the government had already established a viable short term financing alternative to the Bank of England.

Dormant, but not dead

While Ways and Means advances are no longer used, the mechanism isn't dead. The interactive chart below illustrates the Bank of England's balance sheet since 2006. Let's remove all component assets except for ways and means advances, the purple series, and see what we get.

As the chart illustrates, after being paid down in early 2008, Ways and Means advances spiked briefly in late December 2008 to £20 billion only to fall back by April 2009 to £370 million. According to this Bank of England report, the explanation for this spike is that the Treasury briefly borrowed from the Bank to refinance loans that the Bank had earlier made to the Financial Services Compensation Scheme and to Bradford & Bingley.

Bradford & Bingley was a failing bank that was nationalized by the UK government in September 2008. The Bank of England had lent around £4 billion in emergency "Special Liquidity Scheme" funds to Bradford & Bingley as it coped with withdrawals. The SLS had been established earlier that year to improve liquidity of the UK banking system. All Bank of England funding via the SLS was indemnified by the Treasury, so any loss that resulted from supporting Bradford and Bingley up until nationalization would have been absorbed by the Treasury, first by taking on the loan itself and funding that loan via ways and means advances from the Bank of England, and then paying the Bank back by April.

The FSCS, the UK's deposit insurance authority, was able to make good on B&B's deposits through a short term loan from the Bank of England, which was quickly replaced by a government loan financed by Ways and Means advances, which in turn was paid down by the government by April.

Just as Ways and Means mechanism provides the government with the ability to meet sudden spending requirements during war, it provided the same during a period of financial crisis.

Where does the Bank of England stand relative to other central banks?

Although the Bank of England has secured itself a significant degree of financial independence relative to the 1990s and Pitt's era, compared to the Federal Reserve/US Treasury relationship the Bank of England/HM Treasury is much tighter. The Fed has been legally prohibited from granting overdrafts to the government since 1980, as I've outlined here. While Bank of England Ways and Means advances are no longer the modus operandi, they haven't been legally struck out of central bank law as they have in the US. Direct advances to the government could be back one day, with a vengeance.

Compared to the Bank of Canada/Department of Finance relationship, the interface between the Bank of England and HM Treasury is fairly tight. As I've outlined here, the Bank of Canada has the ability to directly lend significant amounts to the government over long periods of time. Indeed, the Bank of Canada is currently purchasing record amounts of bonds in government debt auctions, providing the Finance Department with a continuous overdraft of sorts. Few governments in the western world have the ability to harness their central bank in such a manner.

In general I think it's healthy to establish well defined boundaries between a nation's central bank and its executive branch. Ever since John Law's Banque Royale was nationalized in 1718 and then looted by King Louis XV, scholars have been attuned to the dangers of excessive state control over the issuing power of a nation's monopoly monetary body.

That being said, central bank overdrafts needn't necessarily lead to the sorts of hyperinflation seen in Law's day. The Bank of England provided overdrafts to the Treasury for centuries without igniting prices. The gold standard acted to discipline excess use of the overdraft facility, but in modern days a well-publicized inflation target should be sufficient to reign in any silliness. Absent the discipline imposed by inflation targets, the ability to enjoy central bank financing may be too tempting for a sovereign to forgo. Strict limits or all-out bans on overdraft facilities may provide a needed degree of redundancy.
