What should regulators do about the risks to mid-sized banks?

The failure of three mid-sized banks in March 2023--three of the four largest bank failures in history--shook financial markets and could've spread to other banks if regulators hadn't stepped in. Two on-going trends in finance contributed to these failures: an increase in uninsured deposits and the migration of business lending to non-banks. In a new paper, "The evolution of banking in the 21st century," a group of Harvard researchers looked at regulations that could mitigate risks going forward as well as the potential implications for mergers and acquisitions among mid-sized banks. David Wessel, director of the Hutchins Center on Fiscal and Monetary Policy, hears from two of the authors, Samuel Hanson and Daniel Tarullo, on their findings in this episode of the Brookings Podcast on Economic Activity.
