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….

Can vacancies plunge without a significant rise of unemployment?

The primary objective of central bankers is to maintain low and stable inflation. While this task was never easy, the recent bout of large, adverse supply shocks—from the pandemic to the Russian invasion of Ukraine—combined with massive demand stimulus (both fiscal and monetary) made the task of securing price stability far more difficult.

Our favored indicator of the inflation trend, the Dallas Fed’s trimmed mean PCE price index, rose at a 4.4% annual rate over the past six months, and seems to be accelerating. Furthermore, while activity has slowed, the U.S. labor market remains extraordinarily tight: there are nearly two vacancies for each person who is unemployed—well above the peaks of the early 1950s and the late 1960s.

Against this background, a large, recession-free disinflation seems highly unlikely to us (see our recent post). In theory, a plunge of vacancies could cool a very hot labor market without raising unemployment (see, for example, Waller). In practice, however, the behavior of the relationship between vacancies and unemployment since 1950—what is known as the Beveridge Curve—suggests that this is very unlikely (see Blanchard, Domash and Summers).

That is the subject of this post….

The Costs of Acting Too Little, Too Late

Central bankers that act too little too late risk inflation, recession, or both. Everyone, including the members of the Federal Open Market Committee, knows that the FOMC is late in its current campaign to restore price stability. This makes it essential that they do not do too little.

In this post, we highlight the continued gap between the lessons of past disinflations and the Fed’s hopes and aspirations. We find it difficult to square the FOMC’s latest projections of falling inflation with only modest policy restraint. Simply put, we doubt that the peak projected policy rate from the June Summary of Economic Projections (SEP) will be sufficient to lower inflation to 2% in the absence of a recession.

In our view, boosting the credibility of the FOMC’s price stability commitment will require not only greater realism, but a clarification of how policy would evolve if, as in past large disinflations, the unemployment rate rises by several percentage points. The overly sanguine June SEP simply does not address this key question. Indeed, no FOMC participant anticipates the unemployment rate to rise above 4½% over the forecast horizon….

TradFi and DeFI: Same Problems, Different Solutions

In our recent primer on Crypto-assets and Decentralized Finance (DeFi), we explained that, so long as crypto-assets remain confined to their own world, they pose little if any threat to the traditional finance (TradFi) system. Yet, some crypto-assets are being used to facilitate transactions, as collateral for loans, as the denomination for mortgages, as a basis for ri s k-sharing, and as assets in retirement plans. Moreover, many financial and nonfinancial businesses are seeking ways to expand the uses of these new instruments. So, it is easy to imagine how the crypto/DeFi world could infect the traditional financial system, diminishing its ability to support real economic activity.

In this post, we highlight how the key problems facing TradFi (ranging from fraud and abuse to runs, panics, and operational failure) also plague the crypto/DeFi world. We also examine the different ways in which TradFi and crypto/DeFi address these common challenges.

To summarize our conclusions, while the solutions employed in TradFi are often inadequate and incomplete, features such as counterparty identification and centralized verification make them both more complete and more effective than those currently in place in the world of crypto/DeFi. Ironically, addressing the severe deficiencies in the current crypto/DeFi infrastructure may prove difficult without making highly unpopular changes that make it look more like TradFi—like requiring participants to verify their identity (see, for example, Makarov and Schoar and Crenshaw).

This is the second in our series of posts on crypto-assets and DeFi. In the next one, we will examine regulatory approaches to limit the risks posed by crypto/DeFi while supporting the benefits of financial innovation….

Harry Potter's Monetary Policy Wand?

The Federal Open Market Committee (FOMC) is reassuring us that, so long as we are patient, price stability will return without further pain. But its narrative seems less grounded in historical experience and more like something Harry Potter might have conjured at Hogwarts. By the end of 2024, the Committee expects trend inflation (measured by the price index of personal consumption expenditures excluding food and energy) to drop by more than 3 percentage points while economic growth remains above (and the unemployment rate below) its sustainable level. And, all this magic materializes with the real (inflation-adjusted) policy rate barely turning positive.

The principal means by which the Fed affects the inflation outlook is by influencing financial conditions. Yet, having telegraphed its policy shift for months, the FOMC’s most recent actions on March 16—initiating a series of rate hikes and suggesting that balance sheet tapering could begin soon—barely affected the ease with which firms and households obtain financing. And, while financial conditions are indeed a bit tighter than six months ago—when about one-half of FOMC participants anticipated no interest rate hikes in 2022—these conditions remain quite accommodative (see here).

Is the FOMC’s current policy path consistent with its longer-term price stability goals? In this post, we address this question by exploring policymakers’ newly published projections. Our conclusion is that bringing the inflation trend back to 2% will require a tightening of financial conditions significantly beyond what the Fed currently envisions….

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.…

Comments on Fed CBDC Paper

Last month, the Federal Reserve issued a long-awaited discussion paper on the possibility of introducing a central bank digital currency (CBDC) for retail use. The Fed paper calls for comments on the benefits and risk of introducing a U.S. CBDC, as well as on its optimal design. In this post, we respond to each of the 22 questions posed in the discussion paper. For the most part, these responses are based on our previous analyses of CBDC (here and here).

At the outset, we highlight our doubt that the benefits of a U.S. CBDC will exceed the risks. In our view, other, less risky, means are available to achieve all the key benefits that CBDC advocates anticipate. Moreover, we are not aware of sustainable design features that would reduce the risks of financial instability that many analysts agree will accompany the introduction of a digital U.S. dollar.

However, this overall judgment regarding a CBDC’s benefits and risks is sensitive to two considerations that appear in the Fed’s analysis either explicitly or implicitly. First, CBDC may be a less risky alternative to stablecoins, should regulation of the latter prove politically infeasible (see our earlier post). Second, if other highly trustworthy financial jurisdictions (with convertible currencies, credible property rights protections, and free cross-border flow of capital) offer their own CBDC, the case for a U.S. CBDC—as a device to sustain widespread use of the dollar—would become stronger.

Against this background, we applaud the Fed’s conservative approach. Most important, the U.S. authorities are not rushing to act. Instead, they are thinking carefully about the design elements, are actively engaged in public outreach, and have committed not to proceed without first securing broad public support….
