U.S. Secretary of Defense Sounds Alarm on China’s Taiwan Plans
U.S. Secretary of Defense Pete Hegseth delivered a stark warning at the 2025 Shangri-La Dialogue in Singapore, stating that China is “credibly preparing” to employ military force to alter the Indo-Pacific balance of power, with Taiwan as its primary target. Hegseth emphasized that “the threat China poses is real and it could be imminent.”
Supply Chain Catastrophe and Business Fallout
Taiwan’s significant role in global semiconductor manufacturing—producing approximately 63% of the world’s chips—means that any blockade or invasion would have far-reaching consequences for U.S. tech industries. Major American firms such as Apple, Intel, and Nvidia rely heavily on Taiwanese fabs to produce advanced chips. A Chinese blockade of the Taiwan Strait would severely disrupt U.S. manufacturers’ ability to secure vital components, leading to production line stalls and increased costs.

According to BCA Research, even the prospect of a limited Taiwan conflict could trigger a 10% drop in the S&P 500. Beyond semiconductors, Taiwan exports critical electronic components, petrochemicals, and precision machinery. A Chinese naval blockade would reroute cargo shipping, overburden alternative ports, and inflate shipping rates. In 2023, war-risk rates for ships transiting the South China Sea increased by over 20% as insurers perceived rising threats.
Insurance Industry on Edge
U.S. insurers underwriting war-risk and political violence policies are reassessing their Taiwan exposures. Lloyd’s of London led a tightening trend last year by slashing coverage for Taiwanese ports and boosting war-risk deductibles. In the event of an actual invasion, war exclusion clauses in most standard commercial policies would bar coverage for property damage and business interruption in Taiwan. Businesses without separate war-risk policies would be left entirely exposed, forcing many to absorb catastrophic losses.
Legal and Trade Disruptions
A Chinese blockade contravenes the United Nations Convention on the Law of the Sea (UNCLOS) and breaches World Trade Organization (WTO) principles. U.S. companies could lodge claims before the WTO and UNCLOS tribunals against China, but enforcing awards against a belligerent state remains challenging. Congress may enact sweeping sanctions, triggering export controls, asset freezes, and secondary sanctions targeting Chinese entities.
U.S. Strategic and Legal Responses
Under the Taiwan Relations Act of 1979, the U.S. is obligated to provide Taiwan with defensive armaments and maintain the capacity to resist coercion. An imminent invasion or blockade would likely compel the White House to invoke emergency powers—restricting Chinese imports, freezing Chinese assets in U.S. banks, and deploying naval assets to the Indo-Pacific. Such actions could precipitate direct U.S.–China hostilities, thrusting the region toward a broader war.
Market Reactions and Risk Management
Financial markets are already pricing in this geopolitical tail risk. Following Hegseth’s speech, stock futures plunged while gold and U.S. Treasury yields soared. Hedge funds are loading up on deep out-of-the-money options tied to Taiwan-dependent sectors like semiconductors and shipping. U.S. insurers face escalating headwinds, with war-risk premiums for marine, aviation, and property insurers already climbing.
As tensions escalate, U.S. businesses and insurers must act now to mitigate potential risks. Companies should fortify force majeure language in supply contracts and secure alternative supply chains in allied countries. Insurers must reevaluate underwriting standards, offering customized war-risk policies with transparent coverage triggers while educating clients on standard war exclusion limitations.
