Last month, the President’s Working Group on Financial Markets (PWG) called for the introduction of a regulatory framework for “payment stablecoins”—private crypto-assets that (unlike the highly volatile Bitcoin) are pegged 1:1 to a national currency and “have the potential to be used as a widespread means of payment.” Most notably, to limit the risk of runs, the Report calls for legislation restricting stablecoin issuance to insured depositories.

In this post, we first document the rapid growth of stablecoin usage. We then highlight the features which make stablecoins subject to run risk that, in the absence of appropriate governmental controls, could destabilize the financial system. Next, we consider the three regulatory approaches that Gorton and Zhang (GZ) propose for making stablecoins resilient: the first, and the one favored by the PWG, is to limit stablecoin issuance to insured depositories; the second is to require 1:1 backing of stablecoins with sovereign securities (in the case of the United States and the U.S. dollar, these would be U.S. Treasury issues); and the third is to require 1:1 backing with central bank reserves. We conclude with a brief discussion of whether central bank digital currencies are an appropriate means to displace stablecoins.

To foreshadow our conclusions, we view the PWG proposal as the preferred alternative. However, absent near-term prospects for legislative action, we hope that the Financial Stability Oversight Council (FSOC) will consider—as GZ suggest—using its powers under the Dodd-Frank Act to designate the issuance of payments stablecoins as an activity that is “likely to become” systemically important. FSOC designation would authorize the Federal Reserve to promote uniform standards without waiting years for legislation that authorizes a new regulatory framework.

Some Unpleasant Gold Bug Arithmetic

Most people care far more about the prices of things they purchase—food, housing, health care, and the like—than the price of gold. Not coincidentally, professional economists display a remarkably explicit consensus against forcing the central bank to adopt a policy that fixes the price of gold.

Yet, there are still powerful people who think that the United States would benefit if the central bank’s sole purpose were to restore a gold standard. With the nomination of gold standard advocate Judy Shelton to be a Governor of the Federal Reserve, we feel compelled to take these views seriously. So, here goes.

Several years ago, we emphasized that a gold standard is incredibly unstable. In this post, we address the mechanics of how the U.S. central bank would run the system. In our view, it is incumbent on any gold standard advocate to answer a series of practical questions: What gold price are they proposing? How much gold would the Federal Reserve have to acquire and hold to make the scheme credible? Will the Fed be able to lend to banks and operate as a lender of last resort?

Our answers highlight the operational challenges. Since the Fed initially would commit to holding a particular dollar value (that is, the product of price and quantity) of gold, we need to consider price and quantity together. With the smallest balance sheet we can imagine, our best guess is that the Fed initially would have to triple its gold holdings, driving the price of gold up by two thirds (to about $2,600 per ounce). Then, to maintain the gold standard, the Fed would still need to purchase one-third of world gold production each year. Without gold holdings over and above this minimum, the Fed would not be able to lend at all, much less without limit as it can under a pure fiat money standard….

Monetary Policy Operations Redux

On September 17, the overnight Treasury repurchase agreement (repo) rate spiked to 6%—up from just 2.2% a week earlier and the highest level in more than 15 years (see DTCC GCF repo index). Oddly, this turmoil occurred at a time when the Fed had begun lowering its policy rate for the first time in more than a decade and market participants anticipated further policy easing ahead.

What led to this sudden disruption in short-term funding markets that been relatively calm in recent years? Had the Fed lost control? In our view, the explanation for the sudden rise in overnight interest rates is straightforward: the shrinkage of the Federal Reserve’s balance sheet that began in October 2017 reduced the aggregate supply of reserves gradually to where banks’ demand for reserves was insensitive to interest rates. Consequently, large temporary fluctuations in the supply of reserves that would have had virtually no impact even a few months ago, triggered sizable upward interest rate fluctuations.

Consistent with this view, the Federal Reserve recently took action to prevent a recurrence of the September disorder. At an unscheduled video conference meeting on October 11, the FOMC agreed to additional regular purchases of Treasury bills at least into the second quarter of 2020. The goal of this balance sheet expansion is to maintain reserve balances at least as high as their level in early-September before the turmoil began.

In the remainder of this post, we discuss the evolution of the supply and demand for reserves in recent years. We argue that, because no one—including the Fed—knew the precise level of reserves at which the demand curve would become inelastic, an episode like the one on September 17 was virtually inescapable as reserve supply declined. If our diagnosis of the cause is correct, then recent actions should help put the issue to rest. Yet, given the inevitability of the event―that the day would come when shrinking reserve supply hit the inelastic part of the reserve demand curve―the Fed could (and should) have been prepared. If so, it could have avoided even a temporary dent in its well-deserved reputation for operational prowess….

ECB Paddles Both Ways in the Rubicon

On January 22, the ECB crossed the Rubicon twice – but in opposite directions. In an effort to combat deflation and years of anemic growth, the central bank announced a sustained program of large-scale asset purchases. At the same time, it capped the amount of risk-sharing in the Eurosystem. Other central banks have done the first, but not the second. And, while outright balance sheet expansion helped ease euro area financial conditions somewhat, the limit on risk-sharing works in the other direction. Rowing toward both shores at the same time doesn’t move a boat far or fast...

Central Bank Money Without Inflation?

Except for places like Argentina, Venezuela and Sudan, inflation is remarkably low. In fact, virtually no advanced economy in the world has inflation that is even 5%. In the euro area, the harmonized index of consumer prices is rising at roughly 0.7%. And, in the United States, the consumer price index rose by 1.1% over the past 12 months.
