Banking regulation refers to the rules and oversight that governments impose on banks to ensure financial stability, protect depositors, and prevent systemic crises. Banks are uniquely regulated because they handle other people's money, create money through lending, and their failure can trigger economic-wide damage.
Capital requirements under Basel III require banks to hold equity equal to at least 8% of risk-weighted assets, plus buffers. This ensures banks can absorb losses without failing.
Liquidity requirements ensure banks hold sufficient liquid assets to survive short-term stress. The Liquidity Coverage Ratio requires banks to hold enough high-quality liquid assets to cover 30 days of net cash outflows.
Stress testing simulates severe economic scenarios to verify banks can survive. The Federal Reserve's annual Comprehensive Capital Analysis and Review is the most prominent.
The 2023 failures of Silicon Valley Bank, Signature Bank, and First Republic demonstrated classic vulnerability patterns: concentrated deposit bases, held-to-maturity bond portfolios with unrealized losses, and rapid digital-era bank runs.
Government-backed deposit insurance (FDIC in the US, FSCS in the UK) prevents bank runs by assuring depositors their money is safe up to a limit. The US limit is $250,000 per account.
