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.
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.
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.
Thomas Eisenbach, Kyra Frye, and Helene Hall take a look at what is driving the strong co-movement between aggregate payments sent over Fedwire and total aggregate reserves following the financial crisis.
