What Happened
Indian Oil Corporation, India's largest state-run refiner, purchased a record share of its crude oil from the spot market during Q1 FY27 (April-June 2026) as disruptions from the US-Iran conflict made long-term contract supplies unreliable from the Middle East. The company shifted purchasing strategy to spot markets to secure volumes, but at significantly elevated prices reflecting war premiums and supply scarcity. This purchasing pattern directly drove Indian Oil's Rs 1,140 crore Q1 loss, with crude-cost pressures offsetting refining margins. The shift reveals how extended Middle East conflict forces major refiners in crude-importing nations to absorb spot-market premiums, destroying profitability despite stable demand.
Margin destruction at major refiner signals that import-dependent countries absorb crude-price volatility directly; extended conflict forces refiners to book losses even with stable refining demand
Q1 FY27 ended June 30, 2026; losses reported in August 2026; ongoing exposure as Q2 FY27 advances
Indian Oil reported record spot-market crude purchases for April-June quarter (Q1 FY27 ending June 30, 2026) as a direct response to US-Iran conflict disruption of Middle Eastern supply
