Regulatory Failures

The crisis exposed massive gaps in financial regulation that had widened for decades. Deregulation allowed banks to take increasingly risky bets with inadequate capital reserves and minimal oversight.

Credit rating agencies gave AAA ratings to toxic assets, creating a false sense of security. Regulators lacked authority over the shadow banking system where most risk accumulated. The system designed to prevent crises had been systematically dismantled.

The Dodd-Frank Act attempted to close these gaps by requiring higher capital reserves, stress testing, and restrictions on proprietary trading. But whether the reforms went far enough remains hotly debated as banks continuously lobby to weaken the rules.
