Banking System Vulnerability: 2022 Update

To assess the vulnerability of the U.S. financial system, it is important to monitor leverage and funding risks—both individually and in tandem. In this post, we provide an update of four analytical models aimed at capturing different aspects of banking system vulnerability with data through 2022:Q2, assessing how these vulnerabilities have changed since last year. The four models were introduced in a Liberty Street Economics post in 2018 and have been updated annually since then.
How Can Safe Asset Markets Be Fragile?

The market for U.S. Treasury securities experienced extreme stress in March 2020, when prices dropped precipitously (yields spiked) over a period of about two weeks. This was highly unusual, as Treasury prices typically increase during times of stress. Using a theoretical model, we show that markets for safe assets can be fragile due to strategic interactions among investors who hold Treasury securities for their liquidity characteristics. Worried about having to sell at potentially worse prices in the future, such investors may sell preemptively, leading to self-fulfilling “market runs” that are similar to traditional bank runs in some respects.
Banking System Vulnerability through the COVID-19 Pandemic

More than a year into the COVID-19 pandemic, the U.S. banking system has remained stable and seems to have weathered the crisis well, in part because of effects of the policy actions undertaken during the early stages of the pandemic. In this post, we provide an update of four analytical models that aim to capture different aspects of banking system vulnerability and discuss their perspective on the COVID pandemic. The four models, introduced in a Liberty Street Economics post in November 2018 and updated annually since then, monitor vulnerabilities of U.S. banking firms and the way in which these vulnerabilities interact to amplify negative shocks.
How Does Market Power Affect Fire-Sale Externalities?

An important role of capital and liquidity regulations for financial institutions is to counteract inefficiencies associated with “fire-sale externalities,” such as the tendency of institutions to lever up and hold illiquid assets to the extent that their collective actions increase financial vulnerabilities. However, theoretical models that study such externalities commonly assume perfect competition among financial institutions, in spite of high (and increasing) financial sector concentration. In this post, which is based on our forthcoming article, we consider instead how the effects of fire-sale externalities change when financial institutions have market power.
Banking System Vulnerability: Annual Update

A key part of understanding the stability of the U.S. financial system is to monitor leverage and funding risks in the financial sector and the way in which these vulnerabilities interact to amplify negative shocks. In this post, we provide an update of four analytical models, introduced in a Liberty Street Economics post last year, that aim to capture different aspects of banking system vulnerability.
