Bank regulation is the set of public rules and supervisory practices designed to limit excessive bank risk-taking and protect the stability of the financial system.
Why banks are regulated differently
Banks are special because they fund long-term or risky assets with short-term liabilities that can be withdrawn quickly. That maturity transformation makes them vulnerable to runs and contagion, so failure can spread beyond a single institution.
Main regulatory goals
Regulation usually tries to:
- improve solvency through capital requirements,
- protect liquidity,
- limit risky concentrations or leverage,
- reduce the probability and cost of bank failure.
The trade-off
Stricter regulation can improve stability, but it may also raise compliance costs or reduce credit supply. Economists therefore focus on the balance between financial resilience and the efficient provision of lending and payment services.
