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….

COVID-19 Economic Downturn: What do cyclical norms suggest?

Business cycle downturns come in many forms. Some are big, others small. Some are long, others short. Some result from policy errors or euphoric booms, while others are the consequence of external events.

Nevertheless, downturns have some common features and regularities. Among those that have been reasonably stable over much of the past half century are the relationships among unemployment, activity and federal budget deficits. Using these, we explore the impact of the U.S. COVID-19 economic downturn that began last month.

To sum up, recent labor market developments already make clear that we are in the midst of the deepest recession since the 1930s. In fact, the coordinated shutdown of a large swath of the American economy has made this plunge more rapid than that of the Depression. Whether we are at the start of a second Depression depends greatly on how long we keep the economy in a state of suspended animation.

If the lockdown extends from weeks to months, the short-term pain will turn into long-term scarring. The longer it takes to reopen businesses safely, the more damage we will do to the many linkages and networks (including lender-borrower, supplier-user and employer-employee relationships) that make up the fabric of the economy. As the wave of bankruptcies grows, damage to the financial system will increase, as will the resulting harm to the economy’s productive capacity….

How big should central bank balance sheets be?

In 2007, the Fed’s balance sheet was less than $1 trillion. Today, it is nearly $4.5 trillion. The U.S. experience is far from unique. Since 2007, global central bank balance sheets have nearly tripled to more than $22 trillion as of mid-2014. And, the increase is split evenly between advanced and emerging market economies (EMEs).

So what’s the right size? The answer depends on the policy goals and the nature of the financial system. In the case of the Fed, we expect that it will be able to achieve its long-term objectives with fewer than half of its current assets...
