TL;DR
Taiwan controls about 90% of advanced semiconductors, making it vital to the global economy. China holds leverage through economic and military options that could threaten Taiwan’s chip exports, risking severe global disruptions.
Taiwan’s semiconductor industry, led by TSMC, produces roughly 90% of the world’s most advanced chips, making it a critical node in the global supply chain. China’s increasing leverage over Taiwan’s exports and military options poses a significant risk to the global economy, according to experts.
TSMC, the world’s leading semiconductor manufacturer, supplies nearly all of the advanced chips used in smartphones, electric vehicles, and artificial intelligence. A disruption to Taiwan’s chip exports, whether through military action, economic coercion, or blockade, could trigger a global economic crisis, with impacts far exceeding those seen during the COVID-19 pandemic.
While Taiwan benefits from a “Silicon Shield” — a mutual dependence between the U.S., China, and Taiwan — this shield is not foolproof. China has the capacity to impose economic blockades or conduct customs inspections that could severely limit Taiwan’s chip exports without direct military confrontation. The U.S. and other allies have attempted to diversify supply chains and build domestic manufacturing, but these efforts are still in progress and face limitations.
Why It Matters
This situation underscores the fragility of global supply chains and the geopolitical risks surrounding Taiwan’s semiconductor industry. A major disruption could cause a sharp decline in global GDP, impact manufacturing sectors worldwide, and trigger economic instability. The ongoing tensions between China and Taiwan, therefore, are not only regional but have profound global implications.

Background
Over the past decade, Taiwan has solidified its role as the world’s primary producer of advanced semiconductors, with TSMC at the forefront. The geopolitical dispute between China and Taiwan has intensified, with Beijing asserting claims over Taiwan and increasing military and economic pressure. The U.S. has responded with legislative measures like the CHIPS Act to bolster domestic chip production, but dependence on Taiwan remains high. Past conflicts and current tensions highlight the risk of a supply chain crisis if relations deteriorate further.
“The economic shock from a serious Taiwan disruption would dwarf anything we’ve seen in the postwar period.”

“Our fabs are designed with security and resilience in mind, but they are dependent on a complex global supply chain.”

What Remains Unclear
It remains unclear whether China will pursue military invasion, economic coercion, or a combination of strategies, and what specific actions they might take next. The effectiveness of international measures to safeguard Taiwan’s chip exports is also uncertain, as is the timeline for any escalation.
What’s Next
Next steps include increased diplomatic efforts to prevent escalation, ongoing diversification of global supply chains, and monitoring of China’s military and economic activities around Taiwan. Key upcoming events include high-level talks between the U.S., China, and Taiwan, and potential developments in China’s strategic planning.
Key Questions
Could China completely cut off Taiwan’s chip exports?
Yes, China could impose economic blockades or customs inspections that significantly hinder Taiwan’s ability to export chips, even without military action, which could severely impact global supply chains.
What would happen if Taiwan’s chip exports are disrupted?
A disruption could cause a global economic downturn, with major impacts on technology, automotive, and manufacturing sectors, and could take years to recover from.
Are there alternatives to Taiwanese chips?
While efforts are underway to develop domestic manufacturing in the U.S. and elsewhere, currently, no other region produces chips at the same scale or technological level as Taiwan’s TSMC.
What is the likelihood of military conflict over Taiwan?
The exact likelihood remains uncertain. Experts warn that even without invasion, China’s coercive strategies could destabilize the region and threaten global markets.
