The failure of Silicon Valley Bank on March 10, 2023, came as a shock to most Americans. Even people like myself, a scholar of the U.S. banking system who has worked at the Federal Reserve, didn’t expect SVB’s collapse.

Usually banks, like all companies, fail after a prolonged period of lackluster performance. But SVB, the nation’s 16th-largest bank, had been stable and highly profitable just a few months before, having earned about US$1.5 billion in profits in the last quarter of 2022.
