Iran war choking supply chains
The US‑Israel conflict with Iran has halted key flows—Qatar’s helium output is disrupted and shipping through the Strait of Hormuz is largely stopped—threatening semiconductor manufacturing, fertilizer shipments, and food supply chains. That mix of helium shortages, shipping blockades and fertilizer risk is already forcing firms to model near‑term production shocks and inflationary pressure. (apnews.com; npr.org)
QatarEnergy halted LNG and associated-product production on March 2, 2026 and formally declared force majeure to affected buyers on March 4, 2026 after Iranian strikes at Ras Laffan Industrial City. (aljazeera.com) The U.S. Geological Survey and industry reporting show Qatar supplied roughly one‑third of global helium output before the attacks, meaning the Ras Laffan outage risks removing about 30% of the world’s helium capacity according to multiple market analyses. (pubs.usgs.gov) Marine insurers began cancelling war‑risk cover for Gulf transits in early March, producing an effective halt to routine Strait of Hormuz passages as owners refused voyages without cover and hundreds of vessels stacked offshore. (spglobal.com) Voyage‑tracking analytics showed transit collapses—only four vessels crossed in a recent 24‑hour snapshot versus a weekly average near 77 crossings—while Reuters reported underwriters such as Gard and Skuld issuing cancellations effective March 5. (windward.ai) Fitch and industry groups have named TSMC, Samsung and Intel among firms exposed to helium tail‑risk, and sector analyses note most advanced fabs carry roughly one week of usable helium on site, creating the prospect of yield‑hitting supply interruptions within days to weeks if resupply stalls. (intellinews.com) About one‑third of global seaborne fertilizer transits the Strait of Hormuz, Bloomberg reported, and fertilizer contract prices have already climbed roughly 22% year‑over‑year as major carriers reroute or suspend Hormuz sailings and apply surcharges.
