Parting Reflections on the Series on Large and Complex Banks
The motivation for the Economic Policy Review series was to understand better the behavior of large and complex banks, and we have covered a lot of ground toward that end. We have examined large banks? economies of scale, their proclivity toward risk taking, their possible funding advantages (pre-Dodd Frank), the sources and types of their complexity, and the sources and means of dealer bank financing. We have also looked at resolution issues surrounding large and complex banks, including a case study on the Lehman bankruptcy, a review of resolution methods, and two studies of the rationale ...

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.

The Financial Origins of Non-Fundamental Risk
We formalize the idea that the financial sector can be a source of non-fundamental risk. Households' desire to hedge against price volatility can generate price volatility in equilibrium, even absent fundamental risk. Fearing that asset prices may fall, risk-averse households demand safe assets from leveraged intermediaries, whose issuance of safe assets exposes the economy to self-fulfilling fire sales. Policy can eliminate nonfundamental risk by (i) increasing the supply of publicly backed safe assets, through issuing government debt or bailing out intermediaries, or (ii) reducing the ...

Rollover risk as market discipline: a two-sided inefficiency
Why does the market discipline that financial intermediaries face seem too weak during booms and too strong during crises? This paper shows in a general equilibrium setting that rollover risk as a disciplining device is effective only if all intermediaries face purely idiosyncratic risk. However, if assets are correlated, a two-sided inefficiency arises: Good aggregate states have intermediaries taking excessive risks, while bad aggregate states suffer from costly fire sales. The driving force behind this inefficiency is an amplifying feedback loop between asset values and market discipline. ...

Non-Bank Financial Institutions and Banks’ Fire-Sale Vulnerabilities
Banks carry significant exposures to nonbanks from direct dealings, but they can also be exposed, indirectly, through losses in asset values resulting from fire-sale events. We assess the vulnerability of U.S. banks to fire sales potentially originating from any of twelve separate non-bank segments and identify network-like externalities driven by the interconnectedness across non-bank types in terms of asset holdings. We document that such network externalities can contribute to very large multiples of an original fire sale, thus suggesting that conventional assessments of fire-sale ...

Investment Commonality across Insurance Companies : Fire Sale Risk and Corporate Yield Spreads
Insurance companies often follow highly correlated investment strategies. As major investors in corporate bonds, their investment commonalities subject investors to fire-sale risk when regulatory restrictions prompt widespread divestment of a bond following a rating downgrade. Reflective of fire-sale risk, clustering of insurance companies in a bond has significant explanatory power for yield spreads, controlling for liquidity, credit risk and other factors. The effect of fire-sale risk on bond yield spreads is more evident for bonds held to a greater extent by capital-constrained insurance ...

On Fire-Sale Externalities, TARP Was Close to Optimal
Imagine that many large and levered banks suffer heavy losses and must quickly sell assets to reduce their leverage. We expect the market price of the assets sold to decline, at least temporarily. As a result, any other financial institutions that happen to hold the same assets will experience balance sheet losses through no fault of their own —a negative fire-sale externality. In this post, we show that the vulnerability to fire-sale externalities was high during the crisis and that the capital injections of the government’s Troubled Asset Relief Program (TARP) helped reduce it ...
