China-Taiwan Strait Tensions: Economic Spillover Risk Assessment

1.What Happened

China's People's Liberation Army conducted its largest military exercises around Taiwan since 1996, involving 68 aircraft and 13 warships in a 48-hour period. US Navy positioned three carrier strike groups in the Western Pacific in response.

2.Why It Matters

Taiwan produces 63% of global semiconductors and 90% of advanced chips (below 7nm). Any disruption to Taiwan Semiconductor Manufacturing Company (TSMC) would cascade through global supply chains affecting everything from smartphones to automobiles to military systems.

3.Historical Context

Previous Taiwan Strait crises: (1) 1996 - China fired missiles, US sent carriers, markets dropped 12% then recovered in 6 weeks. (2) 2022 Pelosi visit - Exercises for 10 days, semiconductor stocks fell 8%, recovered in 3 months. No historical case of actual conflict to reference.

4.Key Indicators

Monitoring: (1) Semiconductor stock volatility (SOXX ETF down 6.2%), (2) Shipping insurance rates through Taiwan Strait (+340%), (3) TSMC customer pre-ordering patterns, (4) Pentagon defense readiness levels (currently DEFCON 3 for Pacific Command).

5.Confidence Assessment

64% confidence is LOWER than historical patterns because: (1) No modern precedent of US-China direct military conflict, (2) Multiple possible outcomes (de-escalation, sanctions only, limited conflict, full conflict), (3) Heavy reliance on diplomatic variables that are unpredictable. Base risk score adjusted upward by 15% due to semiconductor concentration risk.

6.What to Watch Next

Critical indicators: (1) Exercise duration beyond 7 days (historical norm), (2) TSMC emergency protocols activation, (3) US diplomatic backchannels (State Department travel), (4) Chinese state media rhetoric shifts. De-escalation typically occurs within 10-14 days historically.
