A small cluster of islands and an even smaller group of equipment makers underpin the world's most advanced chips — and recent conflicts are testing those fragile links. Most advanced logic chips are made in Taiwanese and South Korean foundries, and disruptions to fuels, speciality gases and rare inputs — plus bottlenecks in critical equipment — create knock‑on risks for consumer electronics, automakers, AI projects and defence suppliers.
Where the risk is concentrated
The semiconductor industry separates specialised steps across countries: advanced foundry capacity is concentrated in Taiwan and South Korea, while a handful of equipment makers supply the tools needed for leading nodes. That creates single points of failure.
- Concentrated manufacturing: a large share of sub‑5nm production capacity is located on a few islands and in a small number of fabs, amplifying local shocks.
- Equipment bottlenecks: only a few firms, led by ASML, build the extreme‑ultraviolet (EUV) lithography machines essential for the densest nodes.
- Speciality inputs: gases and materials such as neon, helium and palladium are produced in limited locations and feed directly into photolithography and other chipmaking steps.
Energy and raw materials under pressure
War in the Middle East is changing the routes and costs of fuels and chemicals that fabs rely on. Taiwan imports a significant share of its power feedstocks and has less short‑term strategic storage than some neighbours, leaving shipments in transit vulnerable to disruptions at chokepoints such as the Strait of Hormuz or the Red Sea.
Beyond fuel, helium and other gases used in chipmaking have major processing hubs in the Middle East. Shortages or price spikes in those materials can increase operating costs at fabs and slow production.
Military conflict and supply‑chain lead times
Recent conflicts have already reshaped procurement. The Ukraine war reduced exports of purified neon used in laser lithography, and sanctions and logistics problems have complicated access to other inputs. Those upstream shocks lengthened lead times that had tightened during the pandemic.
Manufacturers report that longer lead times and greater uncertainty force higher inventories, design changes to use older nodes, or delayed production for sectors that require steady delivery — notably automotive, aerospace and defence. Higher fuel prices also raise the operating cost of energy‑intensive fabs and data centres, affecting the cost of building AI infrastructure.

Concentrated manufacturing, dependence on a handful of specialised equipment suppliers, and exposure to fuel and materials routes leave the chip supply chain vulnerable to geopolitical shocks that can ripple through the technology, automotive and defence sectors.
