Iran war pressures supply chains
Escalation around Iran is driving oil, shipping and commodity shocks that threaten margin for energy‑intensive chip production and strain logistics for fabs and packaging—analysts warn oil could spike and inputs like gases and HBM remain vulnerable. The conflict is already forcing scenario planning across semiconductor and manufacturing supply chains. (ft.com)
Ras Laffan Industrial City in Qatar sustained “extensive damage” after missile strikes that halted exports from the world’s largest LNG/helium complex, removing roughly one‑third of global helium production from the market. (cnbc.com; cen.acs.org) (cnbc.com) Industrial‑gas offtakers exposed to Ras Laffan include Air Liquide, Linde and Messer, and QatarEnergy had signed long‑term helium sales agreements (300M–100M cubic feet per annum) with major buyers in 2025–26, leaving limited short‑term alternatives for fabs. (gasprocessingnews.com; mena‑fintech.org) (gasprocessingnews.com) Semiconductor manufacturers in Malaysia and elsewhere report they are “monitoring” helium and other gases but had not yet halted production, even as Fitch Ratings flagged a rising tail‑risk that prolonged tightness would force higher‑cost sourcing, bigger working‑capital needs and production prioritisation at Asian fabs. (reuters.com; fitchratings.com) (msn.com) High‑bandwidth memory (HBM) capacity for 2026 is largely booked under long‑term contracts and analysts say AI demand has redirected wafer starts to HBM, creating acute pricing power for memory suppliers and limiting the ability of GPU and accelerator supply chains to scale. (ainvest.com; bloomberg.com) (ainvest.com) Major carriers including COSCO have suspended Middle East bookings and multiple lines are rerouting vessels around the Cape of Good Hope, a change that adds an estimated 7–15 days to Asia–Europe transit times and coincides with war‑risk premiums for Gulf/Red Sea transits rising to around 0.7–1.0% of vessel value. (bloomberg.com; marinelink.com; reuters.com) (bloomberg.com) Oil markets reacted sharply: Brent crude briefly topped $119 per barrel on March 19 and has risen by roughly 50–57% month‑on‑month amid the conflict, prompting brokerages and agencies to lift their 2026 price forecasts and raising fuel and operational cost assumptions for power‑hungry fabs.
