Iran war chokes supply chains
The Iran war has effectively halted shipping through the Strait of Hormuz and is triggering acute shortages of helium, fertilizers and other commodities — risks that already threaten semiconductor fabs and global food supply. Analysts warn the disruption could ripple into AI hardware production and materials costs if the conflict persists (theguardian.com).
Tanker and commercial-vessel traffic through the Strait of Hormuz has collapsed to a trickle: S&P Global counted just 21 tanker transits since Feb. 28 versus more than 100 per day before the conflict, while maritime intelligence firms report roughly 400 vessels now idling in Gulf of Oman anchorage zones. (cnbc.com) (windward.ai) QatarEnergy halted LNG and associated helium production at Ras Laffan after strikes in early March and declared force majeure on affected deliveries, a shutdown that industry estimates have removed roughly one‑third of global commercial helium (about 63 million cubic metres in 2025) from the market. (cen.acs.org) (agbi.com) Credit‑rating and supply‑chain analysts say semiconductor fabs face a rising tail risk if the helium outage persists, noting regional exposure concentrations and that major Asian chipmakers have completed inventory assessments and mitigation planning. (fitchratings.com) (gasworld.com) Agricultural inputs are being rerouted and repriced: U.S. barge urea trades in New Orleans jumped to about $520–$550/ton in early March from roughly $475/ton the prior week, and analysts estimate 30–35% of global nitrogen exports and large volumes of sulfur are currently constrained by the Gulf disruption. (farmpolicynews.illinois.edu) (financialcontent.com) Marine underwriters and P&I clubs cancelled war‑risk cover for Gulf transits in early March, triggering immediate voyage cancellations and a stacking of more than 150 tankers and LNG vessels outside the choke point as insurers and charterers reassess exposures. (spglobal.com) (maritime-telegraph.com) Hyperscaler and AI data‑center demand that had already prebooked HDD capacity for 2026 compounds the squeeze: Western Digital has said much of its 2026 HDD output is already allocated to major cloud buyers, Seagate has warned the short‑term tech supply impact is limited but contingent on conflict duration, and market analysts expect storage and chip procurement costs to rise if helium and shipping constraints continue.
