Deposit insurance is a key regulatory tool for limiting bank runs and panics. In the United States, the Federal Deposit Insurance Corporation (FDIC) has insured bank deposits since 1934. FDIC-insured deposits are protected by a credible government guarantee, so there is little incentive to run.

However, deposit insurance creates moral hazard. By eliminating the incentive of depositors to monitor their banks, it encourages bank managers to rely on low-cost insured deposits to fund risky activities. In the extreme, with 100% deposit insurance coverage, banks would have virtually no incentive to issue equity or debt.

Against this background, and in light of the events of March-April 2023, we ask what is to be done about deposit insurance. To prevent bank runs, should there be an increase in the legal limit? If so, how can authorities balance the costs of runs and panics against the costs associated with moral hazard, while keeping in mind the potential financial burden on the public? Or, are there alternatives?

We emphasize three promising ways to enhance deposit insurance: a higher insurance cap for small and medium-sized enterprises (SMEs), new resolution rules, and the option to purchase supplementary deposit insurance. In addition, and as regular readers of this blog might expect, we also think that higher capital requirements should be part of the solution: if we require that banks increase the degree to which they finance their assets with capital (rather than deposits), the risk of runs and panics would decline even without raising the cap on deposit insurance….

The Extraordinary Failures Exposed by Silicon Valley Bank's Collapse

The collapse of Silicon Valley Bank (SVB) revealed an extraordinary range of astonishing failures. There was the failure of the bank’s executives to manage the maturity and liquidity risks that are basic to the business of banking: they failed Money and Banking 101. There was the failure of market discipline by investors who either didn’t notice or didn’t care about the fact that the bank was severely undercapitalized for the better part of a year before it collapsed. There was the failure of the supervisors to compel the bank to manage the simplest and most obvious risks. And, there was the failure of the resolution authorities to act in mid-2022 when SVB’s true net worth had sunk far below the minimum threshold for “prompt corrective action.”

Waiting several quarters to act deepened the threat to the financial system, undermining confidence not only in many other banks but also in the competence of the supervisors. The extraordinary rescue actions last week by both the deposit insurer (FDIC) and the lender of last resort (Federal Reserve) are just a sign of the high costs associated with restoring financial stability when confidence plunges.

In this post we discuss each of these four failures, as well as the actions that authorities took to stabilize the financial system following the SVB failure. To anticipate our conclusions, we see an urgent need for officials to do at least five things:

First, to regain credibility, supervisors need to do an immediate review of the unrealized losses on the balance sheets of all 45 banks with assets in excess of $50 billion.
Second, they should perform a speedy and focused stress test on each of these banks to assess the impact on their true net worth of a sizable further increase in interest rates. Any bank with a capital shortfall should be compelled either to issue new equity or shut down. (To ensure the availability of the necessary resources, authorities will need to have a pool of public funds available to recapitalize banks that cannot attract private investors.)
Third, to restore resilience, Congress must reverse the 2018-19 weakening of regulation that allowed medium-size banks to escape rigorous capital and liquidity requirements.
Fourth, the authorities must change accounting rules to ensure that reported capital more accurately reflects each bank’s true financial condition.
Finally, policymakers should assess the impact on the financial system and on the federal debt arising from the now-implicit promise to insure all deposits in a crisis. To limit risk taking, correspondingly greater fees and higher capital and liquidity requirements should accompany any explicit increase in the cap on deposit insurance.

Managing Disinflation

Large, advanced economy central banks are working hard to lower inflation from 40-year highs. Policy rates are up sharply in Canada, the euro area, the United Kingdom and the United States. While disinflation has started, inflation remains far above policymakers’ common target of 2 percent.

Based on their latest projections published in December, most U.S. Federal Open Market Committee (FOMC) participants anticipate a largely benign return to price stability, without a decline in real GDP or a rise of the unemployment rate to much more than 4½ percent. Is this optimism justified? Pointing to the historical record, some prominent analysts wonder whether it is possible to engineer such a large disinflation at what would be such a low cost (see, for example, Lawrence Summers).

This is the setting for this year’s report for the U.S. Monetary Policy Forum that we wrote with Michael Feroli, Peter Hooper and Frederic Mishkin. In the report, we focus on the central challenge facing central banks today: how to minimize the costs of disinflation. To address this question, we employ two approaches: a historical analysis in which we assess the costs of sizable disinflations since the 1950s; and a model-based analysis in which we examine the degree to which policymakers might have been able to anticipate the recent surge of inflation, as well as the path of policy that is likely needed to achieve the desired disinflation.

In the remainder of this post, we summarize the USMPF report’s analysis and conclusions….

Let Crypto Burn

On December 20, one of us (Steve) engaged in a debate with Professor Peter Conti-Brown of the Wharton School on whether crypto should face federal financial regulation. Hosted by the Hutchins Center on Fiscal and Monetary Policy at Brookings, and moderated by Kelly Evans of CNBC, you can watch the one-hour debate here. We found both the questions and the discussion very enlightening. In this post, we will summarize our views, as well as those of Professor Conti-Brown….

The Slippery Slope of a Higher Inflation Target

With inflation significantly above target in most advanced economies, there are renewed calls for central banks to raise their targets from 2% to 3% or 4%, in order to limit the prospective costs of disinflation. In this post, we review the benefits and costs of a higher inflation target.

Yet, regardless of the balance between the costs and benefits of raising the inflation target, our view is that central banks ought not be able to choose their inflation targets. The key problem with such discretion is the slippery slope. If households and firms come to expect that a central bank will opportunistically raise its inflation target to avoid the economic sacrifice associated with disinflation, inflation expectations will no longer be anchored at the target (whatever it is).

To limit the “inflation expectations ratchet”—avoiding perceptions of opportunistic central bank discretion— the Federal Reserve should follow an approach that it now employs regarding the possible introduction of a central bank digital currency: namely, the Fed should announce that it will not alter its inflation target without the explicit support of both the legislative and executive branches, ideally in the form of legislation….

Tales from the Crypt(o)

Every financial system is based on trust. Aside from risks that you consciously take, you are only willing to invest with someone if you are confident that you will get your funds back. For example, someone purchasing a speculative stock through a broker believes that they can sell it quickly at a price, obtaining the proceeds even if that represents a sizable loss.

With the collapse of FTX, we learned yet again that participants in much of the crypto world cannot be so confident. Buying crypto instruments through exchanges that are beyond the regulatory perimeter is far less safe than trading speculative equities through a registered broker-dealer or regulated exchange. Crypto investors who hold their funds in such intermediaries cannot count on having access to the assets that they believe they own.

The run on FTX reflects a classic loss of trust. It exemplifies the problems that plague a financial system in the absence of legal protections and public oversight. Ironically, the crypto movement arose from a desire to create a financial system that does not require legal rules or government intervention to establish trust. Leaving aside diehard believers, the story of FTX (as well as other crypto disasters earlier this year) should expose this for the fantasy that it is….

Financial System Resilience: The Climate Change Edition

Supervisors around the world wish to ensure that the financial system is resilient to climate change. To that end, current best practice is to formulate detailed long-run climate scenarios and then ask whether financial institutions, especially banks, can withstand the losses associated with them. These scenarios typically map the path of surface temperature, sea level, and the resulting economic damage over the next 30 or 40 or 50 years.

However, financial-system stress arises from sudden, widespread changes in the value and perceived quality of leveraged intermediaries’ assets, while climate change is likely to remain gradual over decades. As a result, skeptics reasonably doubt that climate change poses systemic financial risk sufficient to merit the use of scarce supervisory resources and a costly testing apparatus. To quote John Cochrane: “[B]anks did not fail in 2008 because they bet on radios not TV in the 1920s. Banks failed over mortgage investments they made in 2006.”

Fortunately, we now have low-cost, high frequency, forward-looking tools for monitoring climate-related sources of financial instability. In this post, we use one such tool to identify episodes in which the potential influence of climate change on systemic resilience may be worthy of attention. We also look at how an aggregate measure of financial system vulnerability evolves over time….

To improve Fed policy, improve communications

Since May 2021, we have criticized the Federal Reserve’s lagging response to surging inflation. In our view, both policy and communications were inadequate to address the looming challenge. Early this year, we argued that the Fed created a policy crisis by refusing to acknowledge the rise of trend inflation, maintaining a hyper-expansionary policy well after trend inflation reached levels far above their 2% target, and failing to articulate a credible low-inflation policy.

Against this background, we commend the FOMC for its recent efforts. Not only is policy moving quickly in the right direction, but communication improved markedly. In particular, despite the increasing likelihood of a near-term recession, Chair Powell made clear that price stability is necessary for achieving the second part of the Fed’s dual mandate. We suspect that the combination of the Fed’s recent promise to make policy restrictive, along with its improved communications, is playing a key role in anchoring longer-term inflation expectations.

In this post, we focus on central bank communication and its link to policy setting. By far the most important goal of communication is to clarify the authorities’ reaction function: the systematic response of central bank policy to prospective changes in key economy-wide fundamentals—usually inflation and the unemployment rate.

To anticipate our conclusions, we argue for two changes to the FOMC’s quarterly Summary of Economic Projections to better illuminate the Committee reaction function. First, we encourage publication of more detail on individual participants’ responses to link individual projections of inflation, economic growth, and unemployment to the path of the policy rate. Second, we see a role for scenario analysis in which FOMC participants provide their anticipated policy path contingent on one or more adverse supply shocks that present unappealing policy tradeoffs (for example, between the speed of returning inflation to its target and the pace at which the unemployment rate returns to its sustainable level)….

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 ….

Trend inflation: How wages and housing are sustaining momentum

While annual inflation may have peaked, it remains at levels we last saw in the early 1980s. Indeed, our preferred measure of the medium-term inflation trend– the six-month annualized change in the trimmed mean personal consumption expenditure price index—is up by nearly 5 percent. Fortunately, policymakers now realize the severity of the situation and are raising interest rates quickly as they work to catch up. Fed fund futures anticipate a rate of at least 3½ percent by yearend—the most rapid increase in more than 40 years. Will this be enough?

In this post, we address this question. Our conclusion is that policymakers will have to act more aggressively than financial markets anticipate if inflation is to decline to the Fed’s 2-percent target within two years. The reason is that inflation has substantial forward momentum arising from two sources. First, a tight labor market combined with elevated short-term inflation expectations appear poised to drive wage inflation higher. Second, there is the continuing impact of increases in prices of housing, both for owners and renters. So, while energy prices as well as other temporary drivers of the current high inflation are fading, and long-term inflation expectations remain reasonably contained, inflation is currently poised to remain well above 2 percent….
