JKM Surges 58% Year on Year as Japan Weighs Return to Russian Oil Supplies

JKM Surges 58% Year on Year as Japan Weighs Return to Russian Oil Supplies Platts JKM hit .96/MMBtu while G-7 countries make cautious overtures to Moscow for energy supply relief. Platts JKM LNG front-month rose to .96 per MMBtu on May 18, up 10.84% from the previous day and 58.46% higher than the same time last year, according to Trading Economics CFD data. Over the past month alone, JKM has climbed 24.45%. The acceleration reflects a global LNG market where every marginal cargo commands a premium.⁵ With global oil and gas markets in their third month of crisis, G-7 countries have been making cautious overtures to Russia in hopes of stabilising energy supply. Japan NRG reported that the question of whether Japan will return to Russian oil supplies is now being actively discussed. The warring parties show little sign of compromise, and the longer the disruption persists, the more political constraints around Russian energy trade erode.¹ Japan's LNG inventories for power generation stood at 1.98 million tonnes, according to METI data, up marginally from the prior week. Japan remains the world's second-largest LNG buyer and cannot afford to draw down inventories without secured replacement cargoes.⁶ Japan NRG's weekly report highlighted efforts to recycle industrial emissions into usable materials, reducing dependence on fossil-based feedstocks and supporting circular carbon supply chains for hard-to-abate sectors. The technology is expensive and challenging to scale.⁷ Energy storage is entering the Japanese market. Energy Vault entered Japan through a binding agreement to acquire 350 MW of advanced-stage BESS projects targeted to commence construction. Storage projects accounted for roughly 60% of all successful bids in Japan's most recent capacity auction. Energy Vault's stock climbed nearly 31% in its best week since September 2025.^3,2 Japan's consumer economy offers a counterpoint to the energy squeeze. Government data showed higher spending on travel and dining compared to a year ago, supporting electricity demand growth at precisely the moment supply is most constrained.⁴ Trading Economics projects JKM at .47 per MMBtu by quarter-end, implying an 8% decline from spot. That forecast assumes some normalisation in LNG flows. If the Hormuz disruption persists, the projection looks optimistic. EU underground gas storage was 82.7% full, slightly down from 82.8% a week earlier, 12.5% below the same period last year and 9.2% below the five-year average, according to AGSI+ data. The European storage deficit adds competition for the same Atlantic-basin LNG cargoes that Japan needs.⁶ The signal to watch is whether JKM holds above the level through June or whether peace deal momentum pulls it back toward the .47 quarter-end target. Japan's overtures toward Russian supply represent a potential relief valve, but any deal would take months to translate into physical cargoes.^5,1
