Asian LNG slides from $19 toward $15 as the war premium drains out
JKM spikes on the Iran scare and Australian strikes in early June, then falls ~15% on the month as buyers hold back ahead of summer peak
Summary
The Japan-Korea Marker spiked into the low-$19/MMBtu range in early June 2026, driven by Australian strike action, the stalled US-Iran talks and weather demand, then fell to about $15.74 by 23 June, down roughly 15% on the month as the Hormuz war premium drained out and buyers in Japan, South Korea and China held back ahead of the summer peak. Even after the slide JKM ran ~16% above year-ago levels. The marker stayed close to European TTF, the two hubs bidding for the same flexible cargoes, a convergence that will tighten further when new Qatari and US capacity lands.
By the numbers
- ~$19.x/MMBtu, JKM peak in early June 2026.
- $18.92, JKM on 11 June.
- $15.74, JKM on 23 June, down 0.76% on the day.
- ~-15%, JKM move over the month; ~+16% year-on-year.
Why it matters
Asia is the marginal buyer that sets the global LNG clearing price; when JKM falls toward TTF, European refillers face less competition for cargoes. The early-June spike showed how quickly a Middle East scare or a single Australian strike can reprice the world's gas, and how fast it unwinds once supply fear fades.
What to watch
- Whether peak-summer cooling demand in Northeast Asia re-tightens spot before autumn.
- The JKM-TTF spread as the signal for where flexible US cargoes sail.
- Chinese spot buying, the swing factor that can absorb or release Asian length.
