The JKM-TTF LNG arbitrage compressed to $1.225/MMBtu in the week to 1 June, down $0.45 on the week and more than halved since early May. It still points cargoes east, but only narrowly.

Key takeaway

The JKM-TTF arb has more than halved since early May and could flip Atlantic-ward on a sustained TTF break.

The JKM-TTF LNG arbitrage compressed to $1.225/MMBtu in the week to 1 June, down another $0.45 on the week, with Atlantic charter rates back below $100,000/day⁠1. JKM is the Japan-Korea Marker, the Northeast Asia LNG spot benchmark; the spread against TTF governs whether flexible cargoes sail east or stay Atlantic. It has more than halved since it sat at $2.30 in early May, and halved again from the $2.90 to 3.30 range a fortnight before that. Asian spot is no longer pulling cargoes east with the conviction it had through the conflict's first phase.

The arb still points Asia, narrowly. The US prompt route via the Panama Canal remained open at plus $1.021/MMBtu, and North-West Europe DES LNG assessed at TTF minus $0.180, so European import slots are not bidding hard enough to flip flexible cargoes Atlantic-ward.

Monday's TTF surge changes that arithmetic at the margin. A higher hub narrows Asia's edge, and the European benchmark's break above €50 covered in this briefing's lead event shifts the calculus on the next weekly print. Where a sustained €50-plus TTF could finally turn the flow toward Europe is the print to watch.

Deep Analysis

In plain English

LNG stands for liquefied natural gas, which is gas cooled to minus 162 degrees Celsius so it can be loaded onto specialist tankers and shipped anywhere in the world. The main buyers of LNG are in Asia, particularly Japan, South Korea, and China. The JKM (Japan-Korea Marker) is the price buyers in Northeast Asia pay for LNG. The TTF is the price Europeans pay. When Asia pays more than Europe, LNG tankers head east. When Europe pays more, they head west. Right now the JKM-TTF gap is $1.225 per unit. That sounds like Asia is paying more, but after the cost of the 20-day voyage, the extra profit for a tanker owner routing to Asia has shrunk to almost nothing. Monday's European price jump narrowed the gap further. If European prices stay high, some of those tankers may start heading west instead, which would help Europe's gas supplies.
