The JKM-TTF LNG arbitrage compressed to USD 1.225/MMBtu in the week to 1 June, down USD 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 USD 1.225/MMBtu in the week to 1 June, down another USD 0.45 on the week, with Atlantic charter rates back below USD 100,000/day 1. 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 USD 2.30 in early May , and halved again from the USD 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 USD 1.021/MMBtu, and North-West Europe DES LNG assessed at TTF minus USD 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 EUR 50 covered in this briefing's lead event shifts the calculus on the next weekly print. Where a sustained EUR 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 USD 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.

Spokesman Lin Jian rejected Treasury Secretary Scott Bessent's 25 August warning that Iranian oil buyers face an "economic D-Day", saying sanctions do not help and that Beijing would safeguard its own rights and interests. China's Iranian crude imports had already halved for unrelated reasons.

Erbil authorities said 10 explosive-laden drones were shot down over the city on 1-2 September with no casualties. Iraq's government condemned the attacks without naming Iran as their source, and neither Washington nor Baghdad confirmed the IRGC's claim to have hit US bases there.

The General Command said air defences intercepted several Iranian missiles and drones on 1-2 September and called the use of such weapons against civilians and private property a flagrant violation of international humanitarian law.

KUNA reported a hostile Iranian drone struck a residential complex in Kuwait City on 2 September; Fire Force spokesman Brigadier General Mohammad Al-Gharib said losses were confined to property. Kuwait's foreign ministry called the attack a clear breach of its sovereignty.

Petra carried a statement that air defences intercepted eight missiles violating Jordanian airspace early on 31 August and 10 of 13 fired on 1 September. The statement named no target and did not address the IRGC's claim to have struck Camp Titin and killed US personnel.

CENTCOM's 1 September target list named IRGC air defence, radar, maritime and mine-laying sites in Iran but no tanker, after Axios reported anonymous officials describing a Trump-approved "tanker for tanker" drone policy. A CENTCOM spokesman declined to confirm the policy and referred questions to policymakers.
