European gas prices surged 45–54% within hours of QatarEnergy's shutdown announcement. Asian LNG spot prices rose 39%. Oil climbed 13% intraday, pushing Brent above $82 per barrel — up from the $73 level that prevailed before the first strikes and extending the rally that had already taken crude to $85–90.
The European price spike has a specific structural cause. After Russia's 2022 invasion of Ukraine and the rupture of Nord Stream pipeline flows, the EU rebuilt its gas supply around Qatari LNG. Qatar and the United States became Europe's two largest LNG suppliers, replacing the pipeline volumes Moscow had weaponised. Monday's strikes revealed the diversification from Russian gas as a substitution of one geopolitical vulnerability for another — dependence on Russian goodwill replaced by exposure to Iranian military reach.
The compounding effect makes the market response rational. JP Morgan had already raised its recession probability to 35% with Hormuz as the primary variable, and both JP Morgan and Goldman Sachs projected $110–130 oil in a prolonged conflict. Monday added a third simultaneous disruption: Hormuz constrained transit, Ras Tanura reduced refining, and Qatar's shutdown eliminated production at source. Each alone would be absorbable; together, they strip redundancy from a system that had already lost its buffers.
Asian buyers face a separate emergency. Japan depends on LNG imports for virtually all its natural gas and holds roughly three weeks of strategic reserves. South Korea's position is comparable. The 39% Asian spot price increase reflects buyers scrambling for alternative cargoes from the United States, Australia, and Mozambique — none of which can replace Qatar's volume at short notice. For import-dependent Asian economies, the Qatar shutdown is a supply crisis, not a price event.
