SVB 2023: What the Balance Sheet Showed
On the morning of March 10, 2023, California banking regulators seized Silicon Valley Bank and handed control to the Federal Deposit Insurance Corporation. It was the second-largest bank failure in American history, surpassed only by Washington Mutual's collapse in 2008. In the forty-eight hours before that seizure, SVB's stock had fallen more than 60 percent. A bank run had accelerated through Thursday, March 9th, with depositors attempting to withdraw an estimated $42 billion in a single day — roughly a quarter of the bank's total deposit base. The FDIC's takeover was announced before US markets opened on Friday morning. By the following weekend, regulators had also shuttered Signature Bank, and the Federal Reserve had announced an emergency lending facility to prevent the panic from spreading to dozens of other regional institutions. Treasury Secretary Janet Yellen, Fed Chair Jerome Powell, and FDIC Chair Martin Gruenberg issued a joint statement guaranteeing all deposits at both failed banks, invoking a systemic risk exception. Markets lurched. The KBW Bank Index fell more than 15 percent in the span of a week.
SVB's business model had made it structurally vulnerable in ways that, in retrospect, seem almost textbook. The bank served the venture capital and startup ecosystem almost exclusively. During the pandemic boom years of 2020 and 2021, deposits flooded in as VC funding reached historic highs and tech companies parked cash with their preferred lender. SVB's deposit base roughly tripled in two years, growing from approximately $60 billion to nearly $190 billion by the end of 2021. The bank needed somewhere to put that money. Management chose long-duration US Treasury bonds and mortgage-backed securities — assets considered safe in terms of credit quality, but deeply sensitive to interest rate movements. When the Federal Reserve began its most aggressive rate-hiking cycle in forty years, starting in March 2022, those bonds lost value rapidly. SVB was not alone in facing this problem, but it was uniquely exposed: its depositor base was concentrated, sophisticated, and well-networked — exactly the kind of customer base capable of organizing a bank run at digital speed.
