Iran Shuts Hormuz Again and the U.S. Fires Back — Will Natural Gas Ride the War Premium or Fall Back to Earth?
Reports of fresh U.S. strikes against Iran after the IRGC attacked a container ship and shut the Strait of Hormuz jolted energy markets over the weekend. Oil rose and Treasuries fell, with Brent crude climbing more than 3% to $78.50 a barrel as conflicting claims over the strait fueled supply-disruption fears. For U.S. natural gas futures, the picture is more complicated: prices had dropped to $2.90/MMBtu, a two-month low, amid milder weather forecasts, reduced LNG export flows, and comfortable supply. The question is whether the geopolitical risk premium can overpower those bearish domestic fundamentals.
One-Fifth of the World's LNG Just Got Threatened Again
The strait's closure has affected over 10 billion cubic feet per day of global LNG supplies — roughly 20% — mostly from Qatar's Ras Laffan export facility.
The ceasefire and the memorandum of understanding between Washington and Tehran both appear to be dead letters following military and economic escalation.
Shell's 2026 LNG Outlook warned the disruption could produce flat or negative LNG trade growth this year, the first contraction in over a decade.
U.S. Gas Has a Cushion That Limits the Upside
The EIA reported inventories rose 61 Bcf for the week ended July 3, widening the surplus over the five-year average to 185 Bcf.
Freeport LNG's maintenance — running through late August — is temporarily reducing feedgas demand, which mutes the very export channel that would connect U.S. gas to the global shortage. Unlike Brent crude, Henry Hub pricing is largely insulated from Hormuz because the U.S. produces and consumes domestically, and daily U.S. natural gas prices have stayed relatively flat compared with Asian and European prices since the conflict began.
New Export Capacity Could Change the Math by Year-End
The DOE has approved expanded export authorizations at Plaquemines and Elba Island, and approximately 2.4 Bcf/d of new capacity — Golden Pass and Corpus Christi Stage 3 — is expected to come online between April and December 2026. If Hormuz stays contested, that added pipeline to overseas buyers could finally pull domestic prices higher.
The Inflation Wildcard Markets Fear Most
The latest strikes revived concern that elevated energy prices will keep inflation sticky and rates higher for longer, with the two-year Treasury yield climbing to 4.23%, the highest since February 2025. For gas investors, the calculus is binary: a diplomatic resolution sends futures back toward recent lows near $2.90, while prolonged hostilities and rising LNG exports could push prices well above $3.50 by winter. The war premium is real — but so is the storage glut sitting underneath it.
