How prolonged Iran war could choke Asia’s chip and data‑centre boom

A new choke point for Asia’s tech engine

Asia’s technology industry faces a supply‑shock scenario as the Middle East conflict threatens the region’s energy and specialty‑gas inputs, analysts warn. It has been reported that LNG and helium shortages risk crippling semiconductor production and delaying the rapid build‑out of artificial‑intelligence data centres across East and Southeast Asia. Markets have already reacted: South Korea’s Kospi fell nearly 1 per cent, Samsung Electronics slid about 2.4 per cent and Taiwan Semiconductor Manufacturing Company (TSMC) eased roughly 0.5 per cent as oil topped US$100 a barrel and Asia spot LNG prices neared US$20/MMBtu.

Why chips and data centres are vulnerable

Semiconductor fabs consume large volumes of ultra‑pure gases (including helium) and rely on stable, cheap electricity and fuel for inputs and logistics. It has been reported that the Strait of Hormuz — a conduit for about a quarter of seaborne crude and 20 per cent of LNG shipments — remained effectively closed after US President Donald Trump said he would block the channel following the collapse of peace talks with Iran. South Korea, Taiwan and Singapore source between 15 and 35 per cent of their gas from Qatari LNG, and Singapore generates around 90 per cent of its power from natural gas, leaving power‑intensive fabs and cloud campuses exposed. Can Asian chipmakers and cloud operators ride out multi‑year outages?

Geopolitics, repair timelines and wider risks

The risk is not abstract. Qatar’s Ras Laffan complex — said to account for roughly a third of global LNG supply — was struck in March, and Qatar’s energy minister reportedly warned repairs could take three to five years. BMI (a unit of Fitch Solutions) notes Asia’s transmission channel differs from Europe’s: shocks hit through crude, refined products and transport costs, directly raising manufacturing input prices and trade financing strains. Add sanctions, shipping insurance spikes and potential secondary sanctions pressure, and the result is a meaningful drag on chip yields, project timelines and capital allocation for AI infrastructure.

The upshot for Western cloud customers and investors? Expect higher costs and delays in capacity expansion, more regional hedging of supply chains, and renewed urgency in strategies to diversify energy and specialty‑gas sources — or onshore critical processes.
