Economic and Strategic Leverage
Approximately 90 percent of global semiconductors and 60 percent of advanced chips originate from Taiwan. Disruption to this supply chain would cripple US technology, defense, and automotive sectors. The strait also connects to other contested waterways; recent GeoGazet tracking shows security concerns extending across the region, including Houthi control of Bab al-Mandab Strait and tanker attacks in the Strait of Hormuz.
Military Access and Alliance Credibility
Free passage through the Taiwan Strait allows US Navy operations throughout the Western Pacific. American credibility with Japan, South Korea, and Australia depends on maintaining this presence. China's increasing military exercises and blockade threats signal intent to change the status quo, forcing Washington to demonstrate commitment to its security architecture in the region.
