The first-round effect: refined products and LNG, not just crude
US Gulf Coast refiners emerged as some of the clearest beneficiaries of the new wartime pricing regime. Reuters reported the strongest margins in years, record US refined product exports in March, and Gulf Coast refinery utilisation above 95 per cent, against a five-year seasonal norm of roughly 82 per cent. The sharpest strain was concentrated in diesel and jet fuel. ULSD traded at a premium of more than $72/bbl to WTI, versus about $40 before the war, while the gasoline premium widened to nearly $26 from around $18. In other words, the inflationary impulse quickly migrated from crude into refined products, where the pass-through to CPI is usually faster and more severe.
Gas and LNG tightened at the same time. Reuters reported that, on 2026-03-04, JKM rose by 68.52 per cent to $25.393/MMBtu, while Northwest Europe spot LNG climbed by 57 per cent to $15.479/MMBtu, as part of the lost Qatari supply was removed from the market and Atlantic-to-Asia arbitrage reopened. This matters especially for Europe. The region has sharply reduced its dependence on Russian gas, but has become far more reliant on US LNG, leaving it highly exposed to external supply shocks.
