The 2008 banking crisis reshaped global finance, triggering severe market dislocation and deep recessions across advanced economies. Triggered by the U.S. housing market collapse, it exposed fragile risk practices and weak governance across major institutions.
In the years that followed, analysts and regulators emphasized transparency, stress testing, and capital buffers to reduce the probability and cost of future systemic shocks. This overview outlines the causes, impacts, and policy responses that defined the episode.
| Phase | Key Event | Primary Trigger | Main Impact |
|---|---|---|---|
| 2006–2007 | U.S. housing bubble peaks | Rising home prices stall | Subprime mortgage delinquencies increase |
| 2007 | Liquidity stress in securitized markets | Loss confidence in mortgage-backed securities | Credit lines freeze, funding costs spike |
| 2008 | Lehman Brothers collapses | Counterparty risk fear surges | Global panic, steep market drawdowns |
| 2008–2009 | Major bank recapitalizations | Capital shortfalls and runs on shadow banking | State aid, nationalizations, and emergency liquidity |
| 2010–2012 | Regulatory response | G20 and Basel III reforms | Higher capital, liquidity buffers, and oversight |
Origins and Transmission Channels
