How Taiwan became a key part of the electronics supply chain, creating interdependence between Taiwan, China, and the US that has deepened even as tensions rise

Context & Ripple Effects
This FT data-driven piece widens the lens beyond leading-edge chips: core processors, 5G modems, Wi-Fi chips and premium camera lenses are all made in Taiwan, so the island's centrality runs through the whole electronics bill of materials, not just one node. It extends the silicon shield argument from deterrence theory to measured industrial fact.
The arc here is long: semiconductor manufacturing already migrated to Asia while US chip firms contracted out to producers like TSMC (as the WSJ traced in 2020), leaving TSMC caught between Washington's tech dictates and its Chinese customer base. The new reporting quantifies how much deeper that interdependence has grown even as tensions rise.
First-order effects
- Every device maker sourcing processors, 5G modems, Wi-Fi chips or premium lenses from Taiwan now has a single-point-of-failure exposure that a serious disruption to the island would hit across product lines at once, not just in one category.
- TSMC and Taiwan's component suppliers gain bargaining weight from that concentration: their output is indispensable to both Chinese hardware builders and Western device brands simultaneously.
Second-order effects
- Washington's push for semiconductor localization faces a harder sell, since TSMC chairman Mark Liu has argued such moves will not actually improve supply chain resilience — the bottleneck is the ecosystem of components around the fab, which cannot be legislated into Arizona.
- Korean and Taiwanese suppliers that built China's hardware sector during the smartphone boom are positioned to keep serving both sides of the split, echoing how they now reap the AI boom as US curbs sideline China.
Third-order effects
- If concentration holds, Taiwan's component-level dominance functions as mutual hostage-holding — the deeper the interdependence the FT measures, the costlier any disruption becomes for Beijing, Washington, and global device makers alike, which is precisely what the silicon-shield thesis bets on.
- Buyers will keep paying a resilience premium for second sources and localized capacity even where those substitutes under-deliver, because the alternative risk is total exposure to one island's output.
The trend: Electronics supply chains are concentrating ever more value in Taiwan even as geopolitical pressure pushes toward diversification, making compute and components a form of strategic leverage rather than mere commerce.
