Taiwan and TSMC: The Systemic Risk Nobody's Talking About Enough
I have a problem with my tech portfolio.
Not because of valuations. Not because of macro. But because of a small island of 36,000 km² located 180 kilometers from the Chinese coast.
The invisible monopoly that runs the world
Let me give you some numbers that should keep you awake at night:
TSMC produces 64% of the world’s semiconductors in foundry. Samsung, number 2, is at 8.1%. But that’s not even the worst part.
For advanced chips – those that power AI, your iPhone, and practically all modern tech infrastructure – Taiwan produces 92% of global capacity. Ninety-two percent.
TSMC alone manufactures chips for Apple (26% of its revenue), Nvidia, AMD, Qualcomm, Broadcom... Basically, if you own tech stocks, you’re massively exposed to Taiwan whether you realize it or not.
The semiconductor industry represents 25% of Taiwan’s GDP. Taiwan’s chip exports reached $165 billion in 2024, up 22% year-over-year. Over half of these exports go to China and Hong Kong.
Think about that irony for a second.
The scenario nobody wants to imagine
Here’s what keeps Pentagon officials and Wall Street analysts awake at night:
A Chinese invasion – or even just a blockade – of Taiwan would trigger what Representative Michael McCaul called “an electronic shutdown that would shut down the world.”
Bloomberg Economics modeled two scenarios: a full invasion and a simple blockade. The cost? Between $2.7 trillion (blockade) and $10 trillion (invasion) in global economic losses.
To put this in perspective, COVID-19 cost the global economy around $12 trillion. A Taiwan crisis would be in the same ballpark.
But here’s what really terrifies me as an investor: it wouldn’t even take an invasion.
The markets would react at the first sign of serious tension. In 2022, when Nancy Pelosi visited Taiwan, China conducted massive military drills around the island. TSMC’s stock dropped. Tech stocks dropped. And that was just saber-rattling.
A CSIS study with private sector participants showed that even a simple collision between a Chinese and Taiwanese fighter jet would trigger immediate massive sell-offs. Hedge funds would dump their China and Taiwan positions within hours. Any company dependent on Asian supply chains would see brutal corrections.
The direct impact on your stocks
Let’s talk about what this means for the stocks you probably own:
Apple: 100% dependent on TSMC for its A-series and M-series chips. Without TSMC, no iPhones, no iPads, no Macs. Full stop.
Nvidia: 100% dependent on TSMC for its AI GPUs. The H100 and H200 that everyone’s fighting over? Made in Taiwan. Nvidia’s $3+ trillion market cap is built on Taiwanese fabs.
AMD: Same story. Their Ryzen CPUs and EPYC server chips? TSMC. Their new AI accelerators competing with Nvidia? TSMC.
Broadcom: Custom AI chips for hyperscalers? TSMC.
You see the pattern.
A disruption in Taiwan doesn’t just mean these companies lose a supplier. It means they have no alternative for advanced chips. TSMC’s lead in 3nm and upcoming 2nm processes is so massive that no other foundry can replicate it in the short or medium term.
