The Rise in Deposit Flightiness and Its Implications for Financial Stability
Deposits are often perceived as a stable funding source for banks. However, the risk of deposits rapidly leaving banks—known as deposit flightiness—has come under increased scrutiny following the failures of Silicon Valley Bank and other regional banks in March 2023. In a new paper, we show that deposit flightiness is not constant over time. In particular, flightiness reached historic highs after expansions in bank reserves associated with rounds of quantitative easing (QE). We argue that this elevated deposit flightiness may amplify the banking sector’s response to subsequent monetary ...

Intermediation in the Interbank Lending Market
This paper studies systemic risk in the interbank market. We first establish that in the German interbank lending market, a few large banks intermediate funding flows between many smaller periphery banks and that shocks to these intermediary banks in the financial crisis spill over to the activities of the periphery banks. We then develop a network model in which banks trade off the costs and benefits of link formation to explain these patterns. The model is structurally estimated using banks’ preferences as revealed by the observed network structure in the precrisis period. It explains why ...
