Iran war is an energy risk to chip fabs
Analysts now warn the Iran conflict could cause energy shortages that threaten Taiwan fabs if it drags on — Oxford Economics says prolonged disruption could trigger power issues while Politico flags Taiwan’s exposure. Shipping and insurance stress around the Strait of Hormuz — plus hundreds of idling tankers — are already raising the bar for reliable fuel and LNG supplies to semiconductor hubs. ( )
Qatar accounts for roughly one-third of Taiwan’s contracted LNG supplies under long‑term deals, a concentration that became exposed after strikes damaged Qatari export facilities. (politico.com) More than 40% of Taiwan’s electricity is generated from LNG, and the island imports nearly all of that gas—leaving grid supply sensitive to any sustained cut in Qatari exports. (gasprocessingnews.com) Oxford Economics’ scenario work models a two‑month Strait of Hormuz disruption pushing average Q2 oil prices to just below $80 per barrel and warns that higher gas prices would drive electricity‑price spikes that disproportionately hit electricity‑intensive sectors. (oxfordeconomics.com) Vessel‑tracking and industry data show roughly 150 tankers anchored or idling outside the Strait of Hormuz as of early March, creating congestion that delays crude and LNG liftings upstream of Taiwan. (maritimetelegraph.com) Marine insurers have pulled or repriced war‑risk cover for Gulf transits, and analysts report war‑risk premiums and freight surcharges have surged, raising the cost and reliability barrier for fuel and LNG shipments to East Asian semiconductor hubs. (spglobal.com) Bloomberg tracking found at least 40 very‑large crude carriers (VLCCs) waiting in the Persian Gulf in early March, underscoring how crude/tanker chokepoints can quickly strain downstream fuel and LNG logistics. (bloomberg.com) S&P Global estimates TSMC’s current electricity use is about 8% of Taiwan’s power demand, and TSMC’s 2024 annual report explicitly warns that electricity shortages, outages or tariff increases have in the past interrupted its operations. (datacenterdynamics.com) Fitch Ratings has flagged a rising “helium tail risk” for the semiconductor industry should the Iran conflict and Qatar export disruptions persist, noting helium shortages would squeeze key fab processes beyond just power or fuel constraints.
