Despite geopolitical tensions, Taiwan's world-leading semiconductor fabs are completely dependent on specialty gases imported from mainland China. An export restriction on a single chemical, like NF3, could shut down the entire Taiwanese chip industry, an often-overlooked vulnerability.

In a stunning geopolitical shift, US imports from Taiwan (a nation of <30M people) have surpassed those from mainland China as of early 2024. This dramatic change is driven by the AI boom and soaring demand for TSMC's advanced chips, fundamentally re-weighting US economic dependencies in Asia.

Taiwan has less than three weeks of energy reserves. A simple naval blockade preventing LNG and oil shipments could cause a nationwide brownout, shutting down critical semiconductor fabs for over 90 days. This creates a catastrophic global economic risk that requires no military force to execute.

Even as the CHIPS Act brings leading-edge manufacturing to the US, a key vulnerability remains: the chips must be sent back to Taiwan for advanced packaging. This process, essential for high-performance computing, leaves the supply chain exposed.

With 97% of high-end chips and 72% of the global foundry market controlled by Taiwan, specifically TSMC, any disruption—from military blockade to cyberattack—would trigger an 'economic apocalypse.' This massive over-concentration creates a singular, fragile chokepoint with no short-term alternative, threatening the entire global economy.

Beyond financial metrics, the most significant 'tail risk' to the AI boom is the high concentration of advanced semiconductor manufacturing overseas, particularly in Taiwan. A geopolitical conflict could sever the supply of essential hardware, posing a much more fundamental threat to the industry's growth than market volatility or corporate overspending.

Ken Griffin provides a stark economic forecast: if the US loses access to Taiwanese semiconductors, its GDP would plummet by 8% within six months. This would halt manufacturing for critical industries like automotive and aerospace, plunging the economy into a modern-day Great Depression.

Dan Sundheim identifies a potential conflict with China over Taiwan's semiconductor dominance as the single biggest tail risk to the global economy. Since Taiwan produces over 90% of advanced chips, a disruption to this fragile supply chain would be catastrophic, potentially triggering an economic crisis on the scale of the Great Depression.

Recent statements from the CCP suggesting a "peaceful reunification" with Taiwan, potentially driven by an energy crisis, amplify the geopolitical risk to TSMC. This makes investments in non-Taiwanese fabs, like those from Samsung and Intel, strategically critical for the American tech industry.
