The Core Vulnerabilitpy
Taiwan, an island roughly the size of Maryland, produces about 90 percent of the world’s most advanced computer chips. These semiconductors power iPhones, laptops and the vast data centers that drive artificial intelligence systems.
For years, U.S. officials have privately warned executives at major technology firms — including Apple, Nvidia, AMD and Qualcomm — that a Chinese blockade of Taiwan could choke off chip supplies and cripple the American technology industry.
Recent Chinese live-fire military drills around Taiwan have intensified concerns in Washington. U.S. officials now openly describe Taiwan’s semiconductor concentration as one of the world economy’s most dangerous single points of failure.
A 2022 confidential industry report commissioned by the Semiconductor Industry Association estimated that cutting off Taiwan’s chip supply could trigger the largest economic crisis since the Great Depression. U.S. GDP could fall by roughly 11 percent, while China’s economy could shrink even more sharply. Separate estimates suggest a Taiwan conflict could cost the global economy more than $10 trillion.

Why Companies Didn’t Move Faster
The business logic has long been clear. Chips manufactured in the United States are more than 25 percent more expensive due to higher labor, material and regulatory costs. Taiwan Semiconductor Manufacturing Company (TSMC) is widely regarded as technologically superior in producing cutting-edge chips. Meanwhile, U.S. technology firms have historically prioritized quarterly profits over long-term geopolitical risk.
In 2022, the Biden administration passed the CHIPS Act, allocating $50 billion in subsidies to encourage domestic semiconductor manufacturing. TSMC, Intel and Samsung announced major U.S. investments in Arizona, Ohio and Texas.
But building factories is only half the equation. Companies must commit to buying the more expensive U.S.-made chips to justify those plants. Many hesitated.
The Trump administration adopted a more aggressive strategy, using tariff threats to pressure companies into shifting more production to the United States. Under mounting pressure, Nvidia committed to purchasing chips from TSMC’s Arizona facilities, while TSMC pledged to significantly expand its U.S. footprint through additional plants by 2028.
Even with these commitments, projections suggest the United States may account for only around 10 percent of global chip production by 2030 — roughly where it stood in 2020 — as China, Taiwan and other nations simultaneously scale their own investments.

The Geopolitical Clock
In 2021, a senior U.S. military commander warned Congress that China could be prepared to move against Taiwan by 2027. U.S. national security officials have since ranked semiconductor dependence among America’s greatest strategic vulnerabilities.
Russia’s invasion of Ukraine undermined the argument that major powers would avoid military action because of economic costs. The assumption that Beijing would never jeopardize its own economy by attacking Taiwan no longer appears ironclad.

Is the Strategy Finally Changing?
New semiconductor plants are under construction across the United States. TSMC is expanding in Arizona. Nvidia has unveiled the first AI chip wafer produced on U.S. soil. Apple and other major firms have pledged additional U.S. investment to strengthen domestic supply chains.
Yet the technical ecosystem remains deeply intertwined with Taiwan. Even chips fabricated in America may require advanced packaging processes still concentrated in Taiwan before becoming fully functional for AI systems.
Some U.S. officials have articulated a goal of relocating up to 40 percent of Taiwan’s semiconductor manufacturing capacity to the United States. However, constructing and ramping up advanced fabrication facilities takes years — far longer than geopolitical tensions may allow.
The Bottom Line
Taiwan is no longer simply a geopolitical flashpoint. It has become central to America’s economic resilience and technological leadership, especially as artificial intelligence drives market valuations and growth.
Washington has tried subsidies. It has tried tariffs. Companies are moving — but gradually.
If a blockade or conflict in the Taiwan Strait were to occur before supply chains are meaningfully diversified, the consequences could reverberate through Silicon Valley and the global economy in ways policymakers have long feared.
