South Korea and Japan burned 39.7% more coal in April as Hormuz LNG crunch forced a rethink

South Korea and Japan burned 39.7% more coal in April as Hormuz LNG crunch forced a rethink With spot LNG prices roughly doubled and Qatar's output halted, Asia's major importers have leaned hard on coal and scrapped the regulatory caps that once held it in check. Coal consumption in South Korea jumped 39.7% year-on-year in April, and Japan's rose 11.1%, as the Iran conflict choked LNG flows through the Strait of Hormuz and left utilities scrambling for dispatchable alternatives, Reuters reported.^5,6 Spot LNG prices have roughly doubled since the disruption began, and Asian LNG imports have fallen sharply — a swing that has effectively priced spot cargoes out of short-run competition with coal for most of the region's power stack.⁶ Seoul's response has been the most abrupt. The Korean government abolished its spring-time regulatory cap that had historically limited coal-fired plants to 80% capacity utilisation, according to an Oilprice.com report on local policy changes.² Nuclear reactor utilisation was ramped to as much as 80% as well, as an additional buffer against further supply-side shocks.² Five years after more than 40 countries pledged at COP26 to phase down unabated coal by 2030-2040, and three years after the G7 committed to ending international coal financing, one of the signatories has quietly dropped the domestic constraint that was meant to deliver the pledge.² India faces the sharpest arithmetic. The country imports about 60% of its LNG through the Strait of Hormuz, leaving it directly exposed to any prolonged blockage.² Peak power demand hit an all-time high of 257 GW, with coal-fired plants supplying upwards of 75% during peak load periods.² Coal imports from Russia alone jumped 95% in the first quarter, Oilprice.com reported, as buyers sought supply routes that bypassed the Middle East entirely.² The shift is visible in shipping data. BIMCO, the world's largest shipowners' association, recorded coal shipments to South Korea, Japan and the European Union surging 27% year-on-year in April, based on data from the week of May 11 (2026-05-11).³ Qatar halted LNG production as early as March 2 (2026-03-02), removing a major swing supplier from the market precisely as demand for spot volumes rose.³ Global coal imports are on track for the third-highest monthly level on record, according to Oilprice.com citing current trade data.³ The IEA's World Energy Outlook 2025, released on May 20 (2026-05-20), described an energy security environment more complex and fragile than at any prior point in its reporting.⁴ The report called for supply diversification and stronger international cooperation, and flagged a growing infrastructure gap: investment in electricity generation has risen nearly 70% since 2015, yet spending on power grids has increased at less than half that rate, creating potential bottlenecks as demand accelerates.⁴ Analysts at Wood Mackenzie say energy security fears are already delaying coal plant retirements across key Asian and European markets, adding momentum to a shift that was already building before the Hormuz disruption.³ Rising prices and supply concerns have pushed Asian utilities to rely more heavily on coal ahead of summer, particularly to cover electricity demand during nuclear plant maintenance, analysts cited by IDNFinancials said.⁵ The environmental cost is not in dispute. "The shift will impose substantial environmental and public health costs," said Dinita Setyawati, senior energy analyst at Ember, in comments cited across multiple outlets.¹ Some analysts argue the crisis could ultimately accelerate the region's long-term shift toward renewables by exposing the geographic concentration risk of imported LNG.¹ Emerging economies outside China are expected to displace that country as the primary driver of global energy demand growth, IEA projections suggest, placing additional pressure on supply infrastructure that grid investment has not kept pace with.⁴ Physical Newcastle coal traded at $119.80 per tonne as of July 17 (2026-07-17), while JKM Asian LNG stood at $19.92/MMBtu — the spread between the two fuels keeping coal firmly preferred for baseload dispatch at current spot prices. The Korean utilisation cap is gone. Qatar's shutdown, which began March 2 (2026-03-02), remains in effect. Whether those regulatory permissions are reinstated once — and if — the Hormuz route reopens is the immediate policy question, since the answer will shape whether April's coal figures mark a temporary shock or a durable reset in the region's generation mix.^3,2
