The JKM-TTF spread narrowed to roughly USD 2.30/MMBtu in the week to 7 May 2026, down from USD 2.90 to 3.30/MMBtu a fortnight earlier 1. JKM is the Platts Japan Korea Marker, the Asian LNG spot benchmark; TTF is the European wholesale gas reference. The spread is the headline arbitrage input for flexible Atlantic LNG cargoes deciding between east and west routing.
The spread remains positive. Asia still carries the premium, so flexible cargoes still route east on routing-cost arithmetic alone. The narrowing is constructive for Europe's competitive position on the marginal spot cargo, but it does not reverse the underlying picture. The TTF-set arithmetic at EUR 47 and the storage deficit sit unchanged beneath the spread move.
European procurement desks read the move as incremental, not structural. A spread compression of roughly USD 0.60 per MMBtu at the upper end shifts the breakeven on a marginal voyage but not the directional bias. Atlantic cargo bidding will adjust at the margin, while flexible cargoes continue to clear at the Asian premium. The cleaner trigger for a routing reversal would be a JKM-TTF flip into negative territory or a spread compression below the voyage cost differential, neither of which has materialised in the week to 7 May.
