Understanding Financial Crises

Financial crises are rare but devastating events where the financial system stops functioning, credit freezes, asset prices collapse, and the real economy contracts. The 2008 crisis wiped out $22 trillion in global wealth. But crises are preventable—with the right warning systems and safeguards.

⚠️ What Makes a Crisis Systemic?

Not every bank failure or market crash is a crisis. True systemic crises have three characteristics:

1.Contagion: Problems spread from one institution to many through interconnections
2.Credit Freeze: Banks stop lending even to healthy borrowers, strangling the economy
3.Self-Reinforcing: Fear breeds more fear, selling causes more selling, a doom loop

The Anatomy of Past Crises

Every major crisis follows a similar pattern: leverage builds up, a shock hits, panic spreads faster than policymakers can react. But each teaches different lessons.

Common Crisis Patterns

📈

Build-up Phase

Leverage increases, asset prices rise, risk perception falls. "This time is different" mindset.

💥

Trigger Event

Unexpected shock reveals hidden vulnerabilities. Could be default, policy change, or external event.

Contagion Spreads

Interconnected system means problems cascade. Fire sales, margin calls, bank runs multiply the shock.
