Iran War LNG Disruption Sends Asian Derivatives Volumes Surging 251% Year-on-Year
JKM spot sits at $21.82/MMBtu as Iran-driven supply disruption collides with accelerating coal switching in Japan and South Korea.
LNG derivatives trading in Asia jumped 251% year-on-year as the Iran conflict rerouted supply away from established Middle Eastern lanes, oilprice.com reported on Tuesday (2026-07-22), with the hedging surge reflecting commercial uncertainty about where replacement cargoes will come from and at what cost.5
JKM spot stood at $21.82/MMBtu on Thursday (2026-07-24), compared with $17.10/MMBtu recorded on May 19 (2026-05-19). The derivatives acceleration alongside spot signals that commercial participants expect the physical supply dislocation to persist rather than resolve.1,5
India's position shows where the stress is sharpest. Before the Iran war, close to 60% of India's LNG imports arrived from the UAE and Qatar, senior price reporter Suyash Pande wrote for oilprice.com on Tuesday (2026-07-22). Both supply lanes are now constrained by the conflict's effect on Strait of Hormuz shipping, forcing South Asian buyers into already elevated spot markets with few alternatives.5
Yet Japan and South Korea are responding differently. The two countries together account for approximately 35% of global LNG demand, according to EnergyRiskIQ data, and both accelerated coal consumption in April (2026-04) as gas prices climbed. Japan saw coal-fired power supply rise 11.1% in April (2026-04), the fastest pace in at least a year, while gas-fired generation fell 12.9% to 16,447 gigawatt-hours, Reuters reported, citing Japanese Electricity Market figures.2,1
South Korea's shift was larger. Coal-fired output jumped 39.7% year-on-year to 10,733 gigawatt-hours in April (2026-04), the biggest increase since August 2019, while gas-fired generation dropped 6.4%, Korea Power Exchange data showed.2
Japan also moved at the policy level early. On Friday (2026-03-20), the industry ministry presented plans to temporarily lift restrictions on coal-fired power plants, which an expert panel approved, as the government sought to ease the energy crunch from the Middle East conflict.4
The combined effect leaves JKM pulled in opposite directions. Supply tightness from the Iran conflict argues for higher prices. The simultaneous coal substitution across Japan and South Korea removes gas-fired demand that would otherwise sustain upward pressure. For now, the two forces appear to be roughly offsetting each other in spot.5,2
Cargo routing adds a further complication. James Taverner, executive director of global gas and LNG research, noted that suppliers have an incentive to route cargoes to Asia when JKM trades at a premium to northwest European prices, and that cargoes are drawn back west when the premium narrows. EU gas storage stood at 36.6% against a 55.0% seasonal norm as of mid-May (2026-05-19), according to EnergyRiskIQ, giving European buyers reason to compete for available cargoes and tightening Pacific supply when the arbitrage favors westbound flows.5,1
Analysts expect continued upward pressure on JKM if physical shortages deepen, though prices remain well below the records set after Russia's invasion of Ukraine in 2022. But the bearish offset is real: two of Asia's largest power markets are burning more coal and less gas each month.3,2
India's spot buying will clarify the balance in coming weeks. If South Asian demand, stripped of its primary Gulf LNG sources, absorbs the cargoes that Japan and South Korea are releasing through accelerated coal substitution, the supply disruption supports JKM above current levels. If Northeast Asian coal burn outpaces that South Asian spot demand revival, demand destruction could pull JKM lower before northern hemisphere summer peaks.5,2
