The Money Market Mutual Fund Liquidity Facility
In this article, the authors discuss the run on prime money market funds (MMFs) that occurred in March 2020, at the onset of the COVID-19 pandemic, and describe the Money Market Mutual Fund Liquidity Facility (MMLF), which the Federal Reserve established in response to it. They show that the MMLF, like a similarly structured Federal Reserve facility established during the 2008 financial crisis, was an important tool in stemming investor outflows from MMFs and restoring calm in short-term funding markets. The usage of the facility was higher by funds that suffered larger outflows. After the ...

The fragility of short-term secured funding markets
This paper develops a model of financial institutions that borrow short term and invest in long-term assets that can be traded in frictionless markets. Because these financial intermediaries perform maturity transformation, they are subject to potential runs. We derive distinct liquidity, collateral, and asset liquidation constraints, which determine whether a run can occur as a result of changing market expectations. We show that the extent to which borrowers can ward off an individual run depends on whether it has sufficient liquidity, collateral, and asset liquidation capacity. These ...

Gates, Fees, and Preemptive Runs
We build a model of a financial intermediary, in the tradition of Diamond and Dybvig (1983), and show that allowing the intermediary to impose redemption fees or gates in a crisis--a form of suspension of convertibility--can lead to preemptive runs. In our model, a fraction of investors (depositors) can become informed about a shock to the return of the intermediary's assets. Later, the informed investors learn the realization of the shock and can choose their redemption behavior based on this information. We prove two results: First, there are situations in which informed investors would ...

Runs and Flights to Safety: Are Stablecoins the New Money Market Funds?
Similar to the more traditional money market funds (MMFs), stablecoins aim to provide investors with safe, money-like assets. We investigate similarities and differences between these two investment products. Like MMFs, stablecoins suffer from “flight-to-safety” dynamics: we document net flows from riskier to safer stablecoins on days of crypto-market stress and estimate a discrete “break-the-buck” threshold of $1, below which stablecoin redemptions accelerate. We then focus on two specific stablecoin runs, in 2022 and 2023, showing that the same flight-to-safety dynamics also ...

COVID Response: The Money Market Mutual Fund Facility
In this article, we discuss the run on prime money market funds (MMFs) that occurred in March 2020, at the onset of the COVID-19 pandemic, and describe the Money Market Mutual Fund Liquidity Facility (MMLF), which the Federal Reserve established in response to it.

Runs and Flights to Safety: Are Stablecoins the New Money Market Funds?
Stablecoins and money market funds both seek to provide investors with safe, money-like assets but are vulnerable to runs in times of stress. In this paper, we investigate similarities and differences between the two, comparing investor behavior during the stablecoin runs of 2022 and 2023 to investor behavior during the money market fund runs of 2008 and 2020. We document that, similar to money market fund investors, stablecoin investors engage in flight-to-safety, with net flows from riskier to safer stablecoins during run periods. However, whereas in money market funds run risk has ...

Repo runs
The recent financial crisis has shown that short-term collateralized borrowing may be highly unstable in times of stress. The present paper develops a dynamic equilibrium model and shows that this instability can be a consequence of market-wide changes in expectations, but does not have to be. We derive a liquidity constraint and a collateral constraint that determine whether such expectations-driven runs are possible and show that they depend crucially on the microstructure of particular funding markets that we examine in detail. In particular, our model provides insights into the ...

Sophisticated and Unsophisticated Runs
What makes investors run? We show that during the March 2020 run on prime money market funds, institutional and retail investors behaved in dramatically different ways: sophisticated institutional investors ran preemptively based on fundamentals; unsophisticated retail investors ran based on herd-like informational spillovers, leaving funds belonging to families with large institutional outflows. We show that based on website traffic, institutional investors acquired more information on fund portfolios; furthermore, we show that within-family institutional outflows were informative to retail ...

Banking System Vulnerability: 2023 Update
The bank failures that occurred in March 2023 highlighted how unrealized losses on securities can make banks vulnerable to a sudden loss of funding. This risk, which materialized following the rapid rise in interest rates that began in early 2022, underscores the importance of monitoring the vulnerabilities of the banking system. In this post, as in previous years, we provide an update of four analytical models aimed at capturing different aspects of vulnerability of the U.S. banking system, with data through the second quarter of 2023. In addition, we discuss changes made to the methodology ...
