Hormuz tanker attacks keep the Gulf's helium and hardware corridor under strain

The Strait of Hormuz remains the most consequential chokepoint in the war. On 5 November Iran's Revolutionary Guard and army said at least five tankers had been damaged, several after striking naval mines, including a supertanker leaving the eastern strait and a vessel in what the IRGC called an "illegal passageway". The UK Maritime Trade Operations agency separately confirmed a tanker hit by two projectiles about 50 nautical miles north of Qatar's Madinat ash-Shamal, and said it was struggling to count attacks because most ships no longer report them. Washington disputes the mine claims and says mines have been cleared; as of 6 November no Western maritime authority had confirmed the IRGC's mine-strike accounts.

Traffic through the strait, which normally carries around a fifth of world oil, is running roughly 70 per cent below pre-war levels on UKMTO's weekly transit counts, and war-risk premiums for Hormuz transits have been reported at twelve times pre-war rates. On 30 October the Qatari LNG carrier Al Mayeda was struck by unidentified objects, a reminder that gas carriers are as exposed as oil tankers.

For technology supply chains the critical cargo is not oil but helium, and here we draw on earlier reporting to explain the stakes. Qatar supplies roughly a third of the world's helium as a by-product of LNG processing at Ras Laffan, which was hit by Iranian strikes on 28 February. When the strait is closed, LNG storage fills and helium plants must shut; Scientific American reported in March that even an immediate reopening would leave a two-month supply gap, with around 2,000 helium containers stranded. Semiconductors are now the largest helium consumer, using it to cool wafers during etching, and South Korea sourced about 65 per cent of its helium imports from Qatar, putting Samsung and SK Hynix most directly in the firing line.

The consensus among analysts, including Fitch and Epoch AI, is that chip output is resilient: helium is under 1 per cent of wafer cost, fabs have stockpiled since the pandemic and suppliers will prioritise semiconductors over MRI and balloons. The risk is price and logistics rather than shutdown, with spot helium reported well above contract levels and elevated pricing expected for two to three years. The exposure is sharpest for high-bandwidth memory, the component AI accelerators cannot do without.

Why it matters

Every GPU server shipped to India passes through a supply chain whose inputs, from helium to Korean memory to the diesel in the ship, are priced off a strait that Iran can throttle at will. The war has not stopped chip production, but it has added a persistent cost and lead-time premium to AI hardware that will persist until Hormuz normalises.

Indicops view

Indian buyers of AI infrastructure should expect longer lead times and firmer prices on memory-heavy configurations, and should write delivery contingencies into procurement rather than assuming 2025 lead times. For national programmes such as the IndiaAI compute build-out, this argues for phased orders, dual-sourcing where possible and a sober view of how much of the planned capacity actually needs the newest accelerators versus proven previous-generation parts that are easier to obtain.
