John Bovenzi is part of the small club of people who have run a
failed U.S. bank, a group whose membership expanded by two this month when regulators swooped in to take over Silicon Valley Bank and Signature Bank.
In 2008, Mr. Bovenzi, a longtime Federal Deposit Insurance Corp. staffer, took the helm at the failed mortgage lender IndyMac. What he discovered, and what likely faces executives running the latest failed banks: Deposits flood out, but few come in. The employees who haven’t left are looking for other jobs. It is possible some of the remaining higher-ups are responsible for what went wrong—and might even be questioned by law-enforcement officials.
