Scenario analysis

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)….

U.S. Gets a Start on Climate-related Financial Risk

Co-authored with Richard Berner, NYU Stern Clinical Professor of Finance and Co-Director, Volatility and Risk Institute.

Many sources of risk threaten the U.S. financial system. Pandemic risk and cyber risk are at or near the top of our list of nightmares. Yet, with the UN Climate Change conference (COP26) under way in Glasgow, attention is shifting to efforts aimed at limiting the economic and financial damage from climate change, including a timely new “Report on Climate-related Financial Risk” from the U.S. Financial Stability Oversight Council (FSOC).

As the Report makes clear, U.S. policymakers need a far better understanding of climate-related financial risk. Indeed, when President Biden issued an executive order in May instructing financial regulators to conduct a thorough risk assessment, the United States already was behind other advanced economies. As an initial response to the President’s directive, the Report catalogs the range of climate risk threats, describes actions individual U.S. regulators have begun taking to address them, and lists many things that still need to be done. By setting priorities, the FSOC is now putting climate change “squarely at the forefront of the agenda of its member agencies.”

In this post, we highlight three themes in the Report: (1) the ongoing rise of physical climate risk; (2) the conceptual challenges associated with measurement, as well as the data gaps; and (3) the benefits of scenario analysis as a tool for assessing the financial stability risks arising from climate change. The key lesson that we draw from scenario analysis is that a financial system resilient to a range of other shocks is more likely to be resilient against climate risk. Put differently, a less-resilient financial system is vulnerable to all types of shocks, including those arising from climate change.

Stopping central banks from being prisoners of financial markets

Central banks are on the front lines in the fight to limit the impact of the pandemic. They are supporting virtually every aspect of the economy and the financial system. Combined with the massive fiscal support, these policies restored market stability, safeguarded financial institutions, and reduced suffering. Count us among those who firmly believe that everyone would be in worse shape had central banks and fiscal authorities not coordinated this aid as they did.

But, by providing such a broad backstop, the reliance of financial markets on that support can itself become a source of instability. This raises a set of very important and pressing questions: Have central banks’ actions over the past year made financial markets their masters? Can policymakers now be counted on to suppress financial volatility wherever it arises?

We surely hope not, but we see this as a legitimate concern. Fortunately, we also see a solution. Central bankers should strive to duplicate the success of their framework for interest rate policy. That is, they should be clear and transparent about their reaction function for all their policy tools. Knowing how policy will react, markets will respond directly to news regarding economic conditions, and less to policymakers’ commentary. Of course, central bankers cannot ignore shocks that threaten economic and price stability. But cushioning the economy against large financial disturbances does not mean minimizing market volatility….
