A look at the long-term impact on TSMC's business as the US seeks to reduce its dependency on Taiwanese chips and cut China off from key semiconductor supplies
Washington wants the company that dominates semiconductors to move more production to the US but Taipei is resisting
Context & Ripple Effects
TSMC had already been caught between US technology policy and its Chinese customer base in earlier pressure to heed Washington while serving China. Washington’s push to localize more production turns that tension into a question of where TSMC’s capacity is built, while Taipei resists a deeper relocation.
The later record shows the pressure did not remain confined to TSMC: its Taiwan peers expanded US production amid sanctions, export controls and tariff threats, and Morris Chang warned that freer semiconductor trade was faltering.
First-order effects
- TSMC faces competing demands: Washington seeks more US production and tighter limits on China-bound semiconductor supply, while Taipei seeks to retain more production in Taiwan.
- Chinese customers become more exposed to US controls over the supplies TSMC can provide, sharpening the trade-off TSMC was already managing.
Second-order effects
- Foxconn, Wiwynn and Quanta face a parallel incentive to add US capacity as policy pressure reaches the broader Taiwan technology supply chain.
- TSMC’s overseas expansion changes the economic balance of its manufacturing network; the company later forecast margin dilution as overseas fabs ramped, making geographic diversification a cost issue as well as a political one.
Third-order effects
- If Washington continues to tie market access and trade policy to domestic production, semiconductor capacity will be organized more by national alignment than by the free-trade model Chang said was weakening.
- Taipei’s resistance makes TSMC’s footprint a recurring point of negotiation between supply-chain resilience for the United States and Taiwan’s interest in retaining strategic industrial capacity.
The trend: Semiconductor manufacturing is shifting toward politically aligned, geographically diversified capacity, with TSMC at the center of the US-Taiwan-China trade-off.
