TL;DR
Taiwan’s semiconductor industry, led by TSMC, is crucial to the global economy, but China’s strategic options give it leverage that could threaten supply chains. The risk of disruption remains high amid ongoing tensions.
China’s influence over Taiwan’s semiconductor industry, which supplies approximately 90% of the world’s advanced chips, presents a significant threat to the global economy amid rising tensions over Taiwan’s political status.
Taiwan’s TSMC (Taiwan Semiconductor Manufacturing Company) dominates the production of the most advanced semiconductors, critical for smartphones, electric vehicles, and artificial intelligence. Its strategic importance has led experts like Eyck Freymann of Stanford University to warn that a serious disruption in Taiwan’s chip exports could cause an economic shock surpassing anything seen since World War II.
While the so-called “Silicon Shield”—reliance on Taiwan’s chip manufacturing—provides some deterrence, it is not foolproof. China has the capability to impose economic quarantine through coast guard blockades or customs inspections, which could cripple Taiwan’s economy without direct military action. Meanwhile, efforts by the U.S. and allies to develop domestic chip production and restrict exports face enforcement challenges, especially given the global transshipment of chips and components.
In the event of a Chinese invasion or coercion, experts say that the most likely outcome would be sabotage or destruction of Taiwan’s manufacturing facilities, rendering them inoperable. Alternatively, China might seek indirect control through coercive measures like blockades or political pressure, which could still severely disrupt global supply chains.
Why It Matters
This situation underscores the fragility of global supply chains reliant on Taiwan’s chip industry. A disruption could lead to a multi-percentage-point drop in global GDP, affecting everything from consumer electronics to automotive manufacturing. The geopolitical stakes are high, as control over Taiwan’s semiconductor industry equates to economic and technological dominance.
Furthermore, the potential for escalation raises concerns about the stability of regional order and the possibility of conflict. The interconnectedness of supply chains means that even non-military actions by China could have profound global repercussions, making the Taiwan question one of the most critical flashpoints today.

Background
Over the past decade, Taiwan’s TSMC has become the world’s leading producer of advanced semiconductors, with about 90% of cutting-edge chips manufactured on the island. The U.S. has responded with legislation like the CHIPS Act to bolster domestic production, while China has invested heavily to develop its own semiconductor industry, albeit with limited success at the leading edge.
Geopolitical tensions have escalated as China asserts claims over Taiwan, which sits strategically in the first island chain that controls access to the Pacific. The U.S. maintains a policy of strategic ambiguity, supporting Taiwan’s defense while avoiding direct confrontation. Recent analyses warn that even without invasion, China’s coercive measures could significantly impact Taiwan’s chip exports and, by extension, the global economy.
“The economic shock from a serious Taiwan disruption would dwarf anything we’ve seen in the postwar period.”
— Eyck Freymann, Hoover Fellow at Stanford University
“The fabs would be inoperable if attacked or sabotaged, and many depend on foreign equipment and expertise.”

What Remains Unclear
It remains unclear what specific actions China might take in a crisis scenario and how effective international responses would be. The likelihood of a military invasion versus coercive measures is still debated among analysts.

What’s Next
Monitoring developments in U.S.-China-Taiwan relations will be critical, especially any changes in military posturing or diplomatic negotiations. Further discussions at upcoming Xi-Trump meetings may address the issue, but concrete policy shifts are uncertain.

Key Questions
What would happen if China successfully took control of Taiwan’s chip industry?
Control over Taiwan’s chip industry would allow China to influence global supply chains, potentially restricting access to advanced semiconductors and reshaping technological dominance. It could also trigger a global economic crisis.
Can the global economy withstand a disruption in Taiwan’s chip exports?
A severe disruption could cause a significant economic downturn, with estimates suggesting a multi-percentage-point drop in global GDP and widespread impacts across multiple sectors.
What measures are the U.S. and allies taking to mitigate this risk?
The U.S. has passed the CHIPS Act to boost domestic semiconductor manufacturing and is working to develop supply chain resilience. However, enforcement and the global transshipment of chips remain challenges.
Is a military conflict over Taiwan inevitable?
It is not yet clear. Experts warn that coercive measures could cause significant damage without open conflict, but the risk of military escalation remains a concern.
