What the U.S.-Taiwan deal means for the island's 'silicon shield'

Core Insights - The U.S.-Taiwan deal aims to expand chip production capacity in the U.S., but analysts believe it will not fully reduce reliance on Taiwan's advanced semiconductors in the near term, keeping the "silicon shield" intact [1][5] Industry Overview - Taiwan is a dominant player in global chip production, with the Taiwan Semiconductor Manufacturing Company (TSMC) producing a significant portion of the world's advanced chips. Approximately one-third of global demand for new computing power is fabricated in Taiwan [2] Strategic Importance - Taiwan's central role in the semiconductor supply chain is crucial for maintaining its de facto autonomy and deterring potential Chinese aggression, a concept referred to as the "Silicon Shield" [3] Trade Deal Details - Under a recent trade agreement, the Taiwanese government will provide $250 billion in credit to its chip and technology companies to enhance production capacity in the U.S. Additionally, Taiwanese companies will receive higher quotas for tariff-free chip imports into the U.S. In exchange, the U.S. will reduce tariffs on most goods from Taiwan from 20% to 15% and eliminate tariffs on certain categories [4] Production Goals and Challenges - The objective is to relocate 40% of Taiwan's semiconductor supply chain to the U.S., but experts express skepticism about the feasibility of this plan due to Taiwan's strict policies on keeping advanced technology domestically [5] Technology Restrictions - Taiwanese authorities have implemented the N-2 rule, which restricts TSMC's overseas fabrication plants from operating technologies that are at least two generations behind those developed in Taiwan [6]
