Central Banks' New Frontier: Interventions in Securities Markets

In his 2016 book The End of Alchemy, our friend and former Bank of England Governor Mervyn King provided a template for financial reform aimed at reducing the frequency and severity of crises. At the time, we were very cautious for two reasons. First, we believed that adoption of King’s framework would vastly increase the influence of central banks on private financial markets, something that could ultimately lead to a misallocation of resources in the economy and to a diminution of the independence of monetary policy that is necessary for securing price stability. Second, we doubted that most central banks had the technical capacity to implement the proposal.

Well, the landscape has changed significantly. During the pandemic, central banks intervened massively in private securities markets and there now appears to be no turning back. In a number of jurisdictions, monetary policymakers broadened the scale and scope of their lending and intervened directly in financial markets, going significantly beyond even their extraordinary actions during the 2007-09 financial crisis. As a result, we likely will be paying the costs that we feared could accompany the implementation of King’s proposal, so we might as well reap the benefits.

In this post, we discuss central banks’ pandemic interventions and the type of infrastructure needed to support them. We then review King’s proposal, highlighting how adopting his approach would make the financial system safer, while radically simplifying the role of regulators and supervisors ….

Russian Sanctions: Questions and Answers

This post is authored jointly with our friend and colleague, Professor Richard Berner, Co-Director of the NYU Stern Volatility and Risk Institute.

Russia’s invasion of Ukraine is altering global security and economic relationships. In this post, we focus on the financial and trade sanctions imposed on Russia. These sanctions are the most powerful and costly punishments imposed on a major economy at least since the Cold War. Their speed, breadth and coordinated global support appear unprecedented.

Not surprisingly, the impact is immediately visible. The damage to the Russian economy and financial system includes, but is not limited to, a plunge of the ruble (by about 40 percent versus the dollar over the past month amid heightened volatility); runs on domestic banks; a sharp hike in the central bank’s policy rate; imposition of capital controls; shutdown of the Russian stock market; collapse in the value of Russian companies traded on foreign stock exchanges; removal of Russian equities from global indexes; and the collapse of Russia’s sovereign credit rating to junk status.

The purpose of this post is to pose and provisionally answer a series of questions raised by this new sanctions regime.…

The ECB's New Strategy: Codifying Existing Practice . . . plus

When the ECB began operation in 1999, many observers focused on its differences from the Federal Reserve. Yet, since the start, the ECB was much like the Fed. And, over the past two decades, the ECB and the Fed have learned a great deal from each other, furthering convergence.

Against this background, it is unsurprising that the broad monetary policy strategies in the United States and the euro area converged as well. On July 8, the ECB published the culmination of the strategy review that began in early 2020, the first since 2003. The implementation of the new strategy comes nearly one year after the Fed revised its longer-run goals in August 2020 (see our earlier posts here and here).

If past is prologue, observers will exaggerate the differences. Perhaps most obvious, unlike the Fed, the ECB’s strategic update did not introduce an averaging framework in which they would “make up” for past errors. Nevertheless, we suspect that it will be difficult to distinguish most Fed and ECB policy actions based on the modest differences in their strategic frameworks. For the most part, both revised strategies codify existing practice, as they permit extensive discretion in how they employ their growing set of policy tools.

In this post, we summarize the motivations for the ECB’s new strategy and describe three notable changes: target 2% inflation, symmetrically and unambiguously; integrate climate change into the framework; and outline a plan to introduce owner-occupied housing into the price index they target (the euro area harmonised index of consumer prices). While the new strategy can help the ECB achieve its price stability mandate, in our view the overall impact of the revisions is likely to be modest….

Central Bank Digital Currency: The Battle for the Soul of the Financial System

While the conflict is largely quiet and out of public view, we are in the midst of an epic battle for the soul of the financial system. Central banks are thinking about whether they should substitute publicly issued digital currency for the bank-issued digital money that people use every day. How this plays out can profoundly reshape the financial system and make it less stable.

The forces driving government decisions are unusual because there is a widespread fear of losing an emerging arms race. No one wants to face plunging demand for their currency or surging outflows from their financial institutions should another central bank introduce an attractive new means of exchange. But that pressure to prepare for the financial version of military mobilization can lead to a very unstable global system that thwarts monetary control.

Central bank digital currency (CBDC) can take many forms. While some may be benign, the most radical version—one that is universally available, elastically supplied, and interest bearing—has the potential to trigger destabilizing financial shifts, weaken the supply of credit, and undermine privacy….

Understanding How Central Banks Use Their Balance Sheets: A Critical Categorization

This comment is jointly authored by Stephen G. Cecchetti and Sir Paul M.W. Tucker.

Central banks have been reinvented over the past decade, first in response to the financial crisis, and then as a consequence of Covid-19. While trying to maintain monetary stability and promote economic recovery, their balance sheets have ballooned. In 2007, the central banks in the United States, euro area, United Kingdom, and Japan had total assets from 6% to 20% of nominal GDP. By the end of 2020, the Fed’s balance sheet was 34% of GDP, the ECB’s 59%, the Bank of England’s 40%, and the Bank of Japan’s 127%.

Before it is possible to consider how well this worked, it is necessary to be clear about what policymakers’ various operations were trying to achieve. Headline declarations of aiming at “price stability” or “financial stability” are unsatisfactory as they jump to end goals without attending to the motivations for specific operations and facilities. The case of the Fed is illustrative. Among other things, they bought U.S. Treasury bonds, offered to purchase commercial paper, corporate and municipal bonds, and set up facilities to lend directly to real-economy businesses as well as to securities dealers. These cannot be assessed solely on whether, alone or together, each materially improved the outlook for economic activity and inflation.

Without a sense of the intended purpose of each central bank action, it is difficult for political overseers or interested members of the public to hold central banks accountable. Precisely because central banks are independent (rightly in our view), that accountability takes the form of public scrutiny and debate. But we argue that it is also hard for central bankers themselves to do their jobs unless they distinguish carefully—in internal deliberations, and external communication—the rationale for different interventions….

Just Vote NO

On Tuesday, July 21, the Senate Banking Committee will vote on whether to support Dr. Judy Shelton’s nomination to join the Board of Governors of the Federal Reserve System. Accordingly, we are re-posting our July 2019 commentary in which we outlined our strong opposition to Dr. Shelton’s candidacy.

In our view, over the past year, the case against Dr. Shelton has strengthened. The Federal Reserve’s speedy and decisive response to the COVID pandemic is a key reason that the U.S. financial system has steadied and the economy quickly began to recover from the worst shock since the 1930s. Had the United States been operating on a gold standard, as Dr. Shelton has long advocated, these Fed actions would not have been feasible.

Indeed, under a gold standard, instead of easing forcefully and committing to sustained accommodation, the central bank would have been obliged to tighten policy in an effort to resist the 19-percent rise of the gold price since the end of 2019. Just as it did in the Great Depression, this policy would have led us down a path of financial crisis and economic disaster (see our earlier posts here and here).

We hope that the Senate Banking Committee will vote down Dr. Shelton’s candidacy and send a determined message that unambiguously backs the Federal Reserve’s commitment to use every means at its disposal―zero interest rates, large-scale asset purchases, and broad lending programs―to restore economic prosperity and maintain price stability. Barring outright rejection, the Committee should at least move to hold an additional hearing on this nomination, as the Committee minority has proposed….

Central Bank to the World: Supplying Dollars in the COVID Crisis

In his comments at Jackson Hole last year, then-Bank of England Governor Mark Carney highlighted the continuing dominance of the U.S. dollar: it accounts for one-half of global trade invoicing; two thirds of emerging market external debt, official foreign exchange reserves, and global securities issuance; and nearly 90 percent of (one leg of) foreign exchange transactions.

It also is the basis for the Global Dollar system (see our earlier post). The BIS reports that short-term U.S. dollar liabilities of non-U.S. banks total $15 trillion. Foreign exchange forward contracts and swaps—with a gross notional value of more than $75 trillion—add substantially further to U.S. dollar exposures (see here). And, the U.S. Treasury reports that foreigners hold more than $7 trillion of U.S. Treasury securities. To put these numbers into perspective, total assets of U.S. depository institutions are currently $20 trillion. In other words, the U.S. dollar financial system outside of the United States is larger than the American banking system.

Like it or not, the Federal Reserve is the dollar lender of last resort not just for the United States, but for the entire world. The Fed’s role is not altruistic. Instead, it reflects the near-certainty that, in a world of massive cross-border capital flows, dollar funding shortages anywhere in the world will spill back into the United States through fire sales of dollar assets, a surge in the value of the dollar, increased domestic funding costs, or all three.

The Fed’s extraordinary efforts to counter the COVID-19 crisis include aggressive actions to counter dollar shortages outside the United States. In this post, we explore those actions, including the supply of dollar liquidity swaps to 14 central banks (“friends of the Fed”) and—to limit sales that might disrupt the Treasury market—the introduction of a repo facility to provide dollars to the others. We also note the challenges facing countries outside the small inner circle that do not have immediate access to the Fed’s swap lines….

Inflation is not (and should not be) a key worry today

A very simple version of 1960s monetarism has two elements. First, controlling money growth is necessary and sufficient to control inflation. Second, leaving aside a financial crisis, the monetary base―the sum of currency in circulation and commercial bank deposits at the central bank―determines the quantity of money. Putting those together means that, in order to control inflation, all central bankers need to do is ensure that their liabilities grow at the appropriate rate. Conversely, when the central bank’s balance sheet grows quickly, inflation inevitably follows.

This simple monetarist reasoning was still on display in 2010, when Ben Bernanke received this letter from a group of 24 economists warning against further large-scale asset purchases by the Fed. At that stage, the central bank’s assets exceeded 250% of their level in September 2008. Over just over two years, the Fed had purchased roughly $400 billion in Treasury securities and $1 trillion in federally guaranteed mortgage-backed securities. But, as Bernanke explained at the time, the purpose of these asset purchases was to aid the economy in recovering from the crisis-induced recession. Moreover, in contrast to prior norms, since October 2008 the Fed had been paying interest on reserves, raising the opportunity cost for banks to lend.

Subsequent experience proved the letter writers very wrong. The Fed’s balance sheet continued to grow, peaking at $4.5 trillion in early 2015. And, over the decade just ended, inflation (measured by the Fed’s preferred consumption expenditures price index) averaged 1.6%―below the central bank’s long-run goal of 2%. If anything, in recent years, and despite massive central bank balance sheet expansions, inflation both in the United States and in other advanced economies has been too low, not too high.

With central bank balance sheets now surging again, we recount this history in the hopes of blunting any inflation concerns, which we see as profoundly misguided. Over the six weeks ending April 22, the Fed’s assets have grown by the same amount as they did from September 2008 to March 2013. While this does raise some serious concerns, inflation is not high among them….

Pitfalls of a Reserves-only Narrow Bank

Since retiring from the Federal Reserve in mid-2016, our friend Jamie McAndrews has been very busy. Unlike most of us, he is putting his ideas into action: in 2015, he and a number of his colleagues, proposed the creation of segregated balance accounts (SBAs). As they write, “SBAs are accounts that a bank or depository institution (DI) could establish at its Federal Reserve Bank using funds borrowed from a lender.” Their proposal is that a bank would offer a special account that it is fully collateralized by a deposit at the Federal Reserve. Furthermore, the SBA deposits would be remunerated at the interest rate the Fed pays on excess reserves (the IOER), minus a small fee for the bank.

We have no expertise whatsoever in determining whether the Fed has legal grounds for denying TNB a Master Account—the subject of the court case in the opening quote. But we do have concerns about SBAs and narrow banks: we worry that they would shrink the supply of credit to the private sector and aggravate financial instability during periods of banking stress. Compared to what may be large costs, we suspect that the benefits would be small….

Universal Central Bank Digital Currency?

Digital currency is all the rage. Bitcoin has more than one thousand crypto cousins. There is even a token called dentacoin, whose issuers claim it will transform dentistry! In the past, we have been clear in our views. We agree with BIS General Manager Agustín Carstens: these are exactly like past attempts of people to issue their own private money. As Carstens said on another occasion, these tokens are “a combination of a bubble, a Ponzi scheme and an environmental disaster.”

Regardless of whether the blockchain will revolutionize dental health, the appearance of cryptocurrencies has driven central banks to think about one particular aspect of their business: paper currency issuance.

In this post, we expand on some aspects of our earlier discussion of central bank digital currency (CBDC). What is it and what would its wider introduction mean for the financial system? Our conclusion is unambiguous: Watch out what you wish for! ….
