TSMC expected to announce $100B investment in U.S.

TSMC in the U.S. vs. Taiwan’s “Silicon Shield”

  • Many argue moving cutting‑edge capacity to the U.S. weakens Taiwan’s main deterrent: if chips can be made in Arizona, Washington has less reason to risk war to save fabs in Hsinchu.
  • Others counter that U.S. security ties to Taiwan long predate TSMC, and Taiwan’s value is as a naval choke point against China, not just a chip source.
  • Several see the deal as coerced: invest “$100B in America or face crushing tariffs,” benefiting TSMC shareholders and the U.S. but eroding Taiwan’s leverage.

Will the U.S. Actually Defend Taiwan?

  • A dominant thread: after Afghanistan and especially Ukraine, many doubt the U.S.—and especially the current administration—would fight China over Taiwan.
  • Some think the most likely U.S. role is sanctions, arms, and intelligence, not direct combat; others think even that support is now in question.
  • There’s debate over public willingness to accept a draft and casualties in a China war; several think domestic opinion and isolationism would block intervention.

China’s Options: Invasion, Blockade, or Slow Squeeze

  • Disagreement over China’s military capability and intent:
    • One side: amphibious assault across ~100 miles of sea against a defended island is extraordinarily hard; war would devastate China’s trade‑dependent economy.
    • Other side: ideology (“reunification,” ending the “century of humiliation”) trumps economics; China would accept huge costs and may not care much about TSMC itself.
  • Blockade and gray‑zone pressure (drills, harassment, cyber, economic coercion) are widely seen as more realistic than a sudden Normandy‑style landing.

CHIPS Act, Tariffs, and Rule‑of‑Law Concerns

  • Commenters note the CHIPS Act was a prior administration’s work; current officials are firing staff and trying to redirect or withhold funds while simultaneously claiming credit for the TSMC deal.
  • There’s anxiety about an emerging practice of using tariffs and impoundment to override Congress and extract industrial concessions, and about the broader erosion of legal constraints.

Foxconn Redux? How Real Is $100B?

  • Many recall the failed Foxconn–Wisconsin mega‑plant and see strong PR parallels.
  • Others argue this is more credible: TSMC’s first Arizona fab is built and ramping, a second is under construction, and tools are already ordered. Still, some expect “announce big, quietly scale back later.”

Why the U.S., Not Europe?

  • Reasons floated: U.S. market size, security guarantees, and tariff threats; Europe’s higher energy costs; and the fact that much of the tooling (ASML etc.) and U.S. IP are already tightly bound into the American ecosystem.
  • Some Europeans worry that if the U.S. becomes protectionist and unreliable, the EU will be forced to build its own fabs and energy base anyway.
