Taiwan makes ~90% of the world's most advanced chips through TSMC. A serious disruption there isn't a regional story — it's a global supply shock. Pick a scenario below to see a reasoned, illustrative path for the major indices, safe havens, and the sectors that would get hit or bid.
China encircles Taiwan, inspects/turns back shipping. No shots fired, but trade and chip flow choke. A standoff measured in weeks.
Missile exchanges, blockade enforced by force, TSMC fabs go offline. U.S. carriers move in; no full invasion yet.
Amphibious invasion, direct U.S.–China combat, advanced-chip supply offline indefinitely. A global, GFC/COVID-scale shock.
A Taiwan shock is the one tail risk that hits a growth book like ours directly, because the AI-capex trade runs through TSMC. That's exactly why a real plan isn't all-in on any single theme: the same event that craters semis is what bids defense, energy, gold, and Treasuries. The playbook isn't to predict the invasion — it's to own enough of the other side that a shock is survivable, keep a cash/short-Treasury reserve to buy the panic, and rebalance on the way down. Historically the deepest, fastest crashes (COVID −34% in 33 days, the 2008 GFC) recovered fully for investors who stayed mechanical and didn't sell the bottom. Diversification and dry powder are the hedge — not a forecast.
This week's China watch (updated June 5): TSMC's CEO pushed back on fears it's falling behind — it has already bought ASML's newest High-NA chipmaking machines (up to $400 million each) and will deploy them when economical, not before. The Five Eyes intelligence alliance warned that Chinese military intelligence is using fake recruiter profiles on LinkedIn — 20,000+ people approached in the U.K. alone, targeting Indo-Pacific security-clearance holders. Beijing clamped down on the 37th Tiananmen anniversary. And the week's quietest strategic story: Sunshine Silver's hot IPO included plans to refine antimony — a mineral China dominates that's needed for chips, night vision and munitions. The reshoring theme keeps broadening.
