The structural footprint of a bank run
Summary
Patrick McKenzie analyzes the 2023 banking crisis, arguing that regional banks failed because they sold their "deposit franchise" natural hedge against interest rate risk. He explains how regulators incentivized banks to buy mortgage-backed securities, creating massive exposure when rates rose. The episode details how digital banking and improved information flow accelerated deposit flight, leading to insolvency. McKenzie concludes that while the system will likely muddle through with public support, the structural vulnerabilities remain significant.
