Bank Failures Through History
Over 17,000 US banks have failed since 1864. The peak was the early 1930s, with over 9,000 failures (40% of all US banks) during the Depression. Deposit insurance (FDIC, 1933) ended panic-driven runs but not insolvency-driven failures. The 2008 wave and the 2023 regional banking turmoil each affected far fewer institutions than the 1930s but disrupted larger ones.
Key insights
The 1930s remain the high-water mark
Roughly 9,000 US banks failed 1930–33 — 40% of all banks then operating. The cause was a combination of contagion bank runs, agricultural distress, and the absence of any deposit insurance. The Banking Act of 1933 created the FDIC and ended depositor-run-driven failures. No subsequent US banking crisis has matched the 1930s in number of failures.
Speed of failures has accelerated
Continental Illinois (1984) was the largest bank failure of the 1980s and unfolded over weeks. Washington Mutual (2008) failed in 8 days. Silicon Valley Bank (2023) failed in 36 hours. Digital banking, social-media-amplified runs, and concentrated depositor bases (SVB's tech clients) have compressed the timeline. Regulatory response (FDIC + Fed) has matched the speed, but the playbook is being rewritten.
European banking crises follow a different rhythm
European bank distress is dominated by 2008–11 (Northern Rock, Fortis, Dexia, Anglo Irish, Bankia) and the 2010–13 eurozone crisis. Resolution mechanisms differ — the Single Resolution Mechanism (2014) imposes losses on bondholders and large depositors before public funds, which has shaped Italian and Spanish bank behaviour ever since. Credit Suisse's UBS-led rescue (March 2023) was orchestrated rather than market-cleared.

Total FDIC-insured and uninsured bank failures
Key Finding: The 1930s towered over every other decade. The 1980s S&L crisis and post-2008 wave each produced sustained failures over ~5 years.

Key Finding: Washington Mutual (2008) remains the largest US bank failure ever; SVB (2023) is the second.
Methodology & caveats
What counts as a 'failure'
FDIC definition: a bank that is closed by its chartering authority and put into receivership. Mergers under pressure (JPM-Bear Stearns 2008, UBS-Credit Suisse 2023) are not 'failures' technically but represent the same kind of distress. Open-bank assistance (extending guarantees without closing) was used in the 1980s but is rare today.
Number vs size
The 1930s failed 9,000 small unit banks; SVB alone in 2023 was $209B. Number of failures is a poor proxy for systemic impact when banks differ in size by orders of magnitude. Aggregate failed-bank assets, deposit losses, and resolution costs are more meaningful measures.
Deposit insurance changes everything
Pre-1934 US: any depositor could lose their deposits when a bank failed → bank runs were rational → small bad news could cascade. Post-FDIC: insured depositors (now $250k per account per bank) face no loss → no run incentive → failures are about insolvency, not panic. 2023 demonstrated that uninsured depositors still run, especially when concentrated.
