Consequence #4 — 90% of Advanced Chips. One Island. Eight to Twelve Years to Rebuild.

Numbers have a way of becoming abstract when they get large enough. So let us make this one concrete.

Taiwan Semiconductor Manufacturing Company — TSMC — accounts for approximately 70% of global foundry revenue and produces nearly all of the world’s most advanced chips: the sub-3nm processors that power the iPhone in your pocket, the Nvidia GPU training the AI models reshaping every industry, the chips inside the car you drive, the medical device keeping someone alive in a hospital.

Taiwan as a whole is responsible for over 90% of advanced chip production globally.

A conflict that damages, destroys, or places under Chinese control those fabrication facilities does not create a shortage. It creates an absence. There is no warehouse of advanced chips that the world can draw down while new capacity is built. Production stops. Immediately. Globally.

Building a new semiconductor fabrication plant — from groundbreaking to volume production — takes approximately five to seven years and costs between $15 and $30 billion per facility. Rebuilding the equivalent of Taiwan’s total advanced chip output would require dozens of such facilities, coordinated across multiple countries, at a scale of investment that has no peacetime precedent. Conservative estimates: eight to twelve years to approximate replacement capacity.

Every product category that uses advanced chips — smartphones, laptops, cars, industrial automation, military systems, medical devices, data centres — faces production stalls within weeks of a supply cutoff. The cascade through dependent industries extends the impact across virtually every sector of the global economy.

Consequence #5 — $14 Trillion at Risk, and That’s Before You Count South Korea and Japan. The financial market exposure concentrated in TSMC’s ten largest clients — and the geographic concentration of collateral damage.

⚡ The consequence to watch

The 8–12 year rebuild timeline means that even a conflict that ends quickly leaves a decade-long economic wound. Business continuity planning for “Taiwan disruption” cannot be a six-month bridge strategy. It needs to be a structural redesign.

🔧 The drill

For every product or service your business delivers that contains a chip, identify: what is the oldest fabrication node that chip could be replaced by? Older nodes (28nm, 40nm) have more diversified production and are less Taiwan-concentrated. Knowing your node dependency is the first step in any meaningful supply chain resilience plan.
