Korean Steel Stocks Surge on Trump Alaska LNG Mention as JKM Holds Near Five-Month High
South Korean pipe and steel shares hit daily limits after Trump invoked Alaska LNG, amplifying supply pressure on a JKM market near five-month highs.
Shin Steel hit its daily upper limit and Kumkang Steel jumped 17.68% on Wednesday (2026-09-02) after President Donald Trump again mentioned South Korea in connection with the Alaska LNG pipeline project, driving a broad rally across Seoul's steel and pipe sector. Dongil Steel Lux closed 13.36% higher. KBI Dongyang Steel Pipe rose 8.26% and TCC Steel gained 7.83%.6
The moves reflect a procurement bet. Alaska LNG will require substantial steel pipe capacity, and Korean producers are pricing in potential contract flow if the project advances. But the gap between a presidential mention and signed pipe orders has historically stretched into years, and the Alaska LNG project has generated comparable rallies on previous political gestures.6
The equity surge arrives against a JKM spot market already running at elevated levels. JKM, the benchmark for spot LNG deliveries to Northeast Asia, traded at $23.76/MMBtu in early Friday (2026-09-04) trade, near five-month highs driven by the Strait of Hormuz blockade that pushed prices to their strongest since late March, TRT World reported.3
Asia absorbs nearly 90% of LNG exports from key Middle Eastern producers, according to S&P Global Energy's Platts Commodities Focus podcast, leaving buyers acutely exposed when Hormuz access tightens. Transits through the strait fell to single digits for an entire week through August 21 (2026-08-21), oilprice.com reported, with Trump's "Economic D-Day" campaign against Iran keeping vessels out of the waterway.4,5
The supply loss has already shifted the generation mix. Japan's coal-fired power supply rose 11.1% in April, the fastest pace in at least a year, while gas-fired generation dropped 12.9% to 16,447 gigawatt-hours, Reuters data show. South Korean LNG imports climbed to 42 mtpa, above April levels, according to Goldman Sachs analysis.2,1
Tokyo has responded by pivoting sharply toward US supply. Japan's imports of US crude surged more than eight-fold to a record 891,000 b/d in July, accounting for 36% of total inflows, while US LNG intake jumped 59% as the country diversified away from disrupted Middle Eastern cargoes.5
Underlying demand has also been revised upward. South Korea's government raised its 2040 peak power demand forecast by roughly 27 GW to as much as 165 GW, driven by semiconductor plant and data centre expansion, a revision that complicates its stated goal to phase out coal, which still supplies close to 29% of generation.5
Goldman Sachs flagged in May that Asia LNG imports were running about 4 million tonnes per annum above its 225 mtpa baseline, with China's four-week average import rate rising to 48 mtpa from 36 mtpa in March. The bank expected further gains toward roughly 67 mtpa through the third quarter as inventories rebuilt.1
ICE Brent crude front-month stood at $95.98/bbl in early Friday (2026-09-04) trade, keeping the cost of alternative supply high for buyers rerouting away from disrupted Middle Eastern cargoes. ICE Endex TTF front-month fell 2.59% to €71.76/MWh in Thursday (2026-09-03) trade, pointing to some easing in European gas markets even as Asian benchmarks held elevated.5
ICIS analysts warned that Europe's gas supplies face pressure this winter, with the conflict having delayed the expected recovery of Qatari LNG export volumes during the summer storage window. Qatari flows and Asian spot demand compete across the same Atlantic and Pacific LNG markets, meaning sustained Gulf supply loss hits both regions simultaneously.4
The Korean steel rally is a speculative amplification of a supply disruption already visible in the physical LNG data. Whether Qatar restores regular export volumes before European winter demand peaks, and how far the Alaska LNG project progresses from political statements toward binding procurement, are the two timelines that matter most for where JKM settles through the final quarter.6,4,3
