War in Iran Is Redrawing the Map for Natural Gas

What It Covers

Bernstein Research analyst Bob Brackett explains how the Iran conflict is disrupting global LNG markets, why natural gas pricing is fundamentally fragmented by geography and liquefaction costs, and how US LNG exports are reshaping the energy landscape — with Qatar's Northfield, the world's largest gas field, now offline.

Key Questions Answered

• •LNG cost structure: Transportation consumes roughly 90% of natural gas's total cost — under $1 to extract from shale, $2-3 to reach Henry Hub via pipeline, then $2.50 to liquefy, $1.50 to ship, plus regasification. This cost structure explains why there is no single global gas price, unlike oil where shipping represents only 2-3% of cargo value.
• •LNG capacity lag: New liquefaction terminals require a four-year construction timeline with no spare capacity equivalent to OPEC's oil buffer. The anticipated 2026-2027 LNG glut — predicted because post-Ukraine investment decisions were made four years prior — is now eliminated by the Iran conflict, fundamentally tightening the global supply outlook through the decade.
• •US LNG export growth: US LNG exports have doubled from roughly 10% to nearly 20% of domestic gas consumption (approximately 20 BCF per day) and will continue adding multiple BCF per day through 2030. The Golden Pass terminal in Texas — 30% Exxon, 70% Qatar — is now Qatar's only active LNG revenue source while Middle East facilities remain disrupted.
• •Coal as LNG's price ceiling: When LNG supply tightens, developing economies default to thermal coal as the substitute fuel. Thermal coal prices have already risen 30% year-to-date to $130 per ton, mirroring the pattern seen after Russia's Ukraine invasion when coal hit $300 per ton. Tracking coal prices signals how severe LNG demand destruction is becoming globally.
• •Oil demand destruction threshold: When crude oil price plus crack spreads reaches approximately 7% of global GDP — roughly $180 combined today — the global economy historically contracts and demand collapses. Currently at around $140 combined, markets are approaching but have not yet hit the level that has reliably triggered past recessions and demand destruction events.
