US-Taiwan deal commits $250B to American chip factories, slashes tariffs

The United States and Taiwan struck a trade agreement Thursday that aims to mobilize up to $500 billion in Taiwanese semiconductor investment and government-backed credit guarantees to build advanced chip factories on American soil.

Under the framework, Taiwanese firms are expected to commit a minimum of $250 billion in direct investment, supported by an additional $250 billion in credit guarantees from the Taiwan government.

In exchange, the US will reduce reciprocal tariffs on Taiwanese goods from 20% to 15%, aligning Taiwan with Japan and South Korea.

The Trump administration will also grant temporary import allowances for companies constructing chip manufacturing plants domestically.

Taiwan’s credit framework aims to fund US fab builds

The $500 billion commitment, split between expected direct investment and government-backed credit, represents a structured approach to semiconductor financing.

Direct investment from Taiwanese foundries like TSMC and component suppliers demonstrates Taiwan’s willingness to diversify production outside its home island.

The $250 billion credit guarantee from Taiwan’s government is designed to backstop financing, making it easier for Taiwanese firms to borrow and fund multi-year fabrication plant construction.

Advanced semiconductor fabs typically cost $15 billion to $25 billion each, so the guarantee framework is intended to facilitate building multiple facilities simultaneously.

TSMC, the world’s largest contract chipmaker, appears positioned as a cornerstone participant.

The company has previously announced plans to expand its US manufacturing presence in Arizona with multiple fabrication plants under the CHIPS Act.

The timeline for further expansions and total committed US investment remains subject to market conditions and production demand.

Tariff cuts to 15%

The tariff reduction provides immediate certainty.

By lowering Taiwan’s rate to 15%, the deal matches arrangements with Japan and South Korea, establishing tariff parity among key semiconductor suppliers.

This simplifies supply chains and removes uncertainty that had pressured Taiwanese exporters and US customers in recent years.​

The Section 232 carve-outs represent the deal’s operational component.

During fab construction, Taiwanese chip manufacturers can import up to 2.5 times their planned production capacity without incurring tariffs.

Once plants become operational, that allowance steps down to 1.5 times production capacity.

This framework is designed to prevent tariff-driven delays during the multi-year construction process.​

Strategic rationale and supply-chain context

The deal addresses ongoing national-security concerns about semiconductor supply concentration.

The US currently sources the majority of advanced chips from Taiwan, a geographic concentration that has prompted policymakers to pursue domestic manufacturing capacity.

By creating incentives for Taiwanese chip suppliers to expand US operations, officials aim to build manufacturing redundancy and reduce vulnerability to disruptions in the Taiwan Strait.

The deal complements existing programs like the CHIPS Act, which offers direct federal grants and tax credits for semiconductor manufacturing in the United States.

Together, these mechanisms are intended to shift the global semiconductor manufacturing footprint and create a more resilient domestic supply chain over the coming decade.
