🌐 Financial Contagion and Market Crashes—When One Fall Spreads to All

---

📌 What is Financial Contagion?

Financial contagion refers to the spread of financial shocks from one institution, market, or country to others, like a domino effect. It typically occurs during financial crises, where fear, losses, or instability in one area trigger panic and losses elsewhere.

💬 "When Wall Street sneezes, the world catches a cold."

🔥 What is a market crash?

A market crash is a sudden, sharp decline in asset prices (typically stock markets), often driven by panic selling, economic shocks, or loss of confidence.

• Usually drops 10%–20%+ in a few days or weeks

• Can lead to recessions, bankruptcies, and mass unemployment

🧠 Mechanisms of Financial Contagion

1. Direct Linkages

   • Interconnected banks and institutions

   • Example: Bank A defaults → Bank B takes losses

2. Investor Behavior (Herding)

   • Panic or fear leads to irrational selling

   • Global investors withdraw from similar markets

3. Trade and Capital Flows

   • A crisis in one country impacts trade partners or investors

   • Example: Eurozone crisis → impact on global banks

4. Currency and Debt Channels

   • Devaluation in one economy affects foreign debt in another

   • Defaults may spread via external debt markets
