We use the German Crisis of 1931, a key event of the Great Depression, to study how depositors behave during a bank run in the absence of deposit insurance. We find that deposits decline by around 20 percent during the run and that there is an equal outflow of retail and nonfinancial wholesale...

We document that the quasi-mandatory U.S. flood insurance program reduces mortgage lending along both the extensive and intensive margins. We measure flood insurance mandates using FEMA flood maps, focusing on the discreet updates to these maps that can be made exogenous to true underlying flood...

Does the federal funds rate respond to shocks when aggregate reserves are in the trillions of dollars? Has banks' demand for reserves moved over time? We provide a structural time-varying estimate of the slope of the reserve demand curve over 2010-21. We estimate a time-varying vector...

We analyze how systemic cyber risk in the wholesale payments network relates to adverse financial conditions. We show that at the onset of the COVID-19 pandemic, payment activity increased, became more concentrated, and showed intraday liquidity stress. Cyber vulnerability was elevated in late...

The 2010s saw a profound shift towards jumbo mortgage lending by large banks that are regulated under the Dodd-Frank Act. Using data from the Home Mortgage Disclosure Act, we show that the "jumbo shift" is correlated with being subject to the Comprehensive Capital Analysis and Review (CCAR)...

The value of assets in the digital ecosystem has grown rapidly amid periods of high volatility. Does the digital financial system create new potential challenges to financial stability? This paper explores this question using the Federal Reserve's framework for analyzing vulnerabilities in the...

We study how intermediaries-mortgage servicers-shaped the implementation of mortgage forbearance during the COVID-19 pandemic and use servicer-level variation to trace out the causal effect of forbearance on borrowers. Forbearance provision varied widely across servicers. Small servicers and...

Before the era of large central bank balance sheets, banks relied on incoming payments to fund outgoing payments in order to conserve scarce liquidity. Even in the era of large central bank balance sheets, rather than funding payments with abundant reserve balances, we show that outgoing...

In June 2022, the Federal Reserve started reducing the size of its balance sheet, which had expanded to just under $9 trillion in response to the COVID-19 pandemic. However, whereas banks' reserves at the Federal Reserve have decreased, the investment of money market funds (MMFs) at the Federal...

Corporate credit lines are drawn more heavily when funding markets are more stressed. This covariance elevates expected bank funding costs. We show that credit supply is dampened by the associated debtoverhang cost to bank shareholders. Until 2022, this impact was reduced by linking the interest...
