Platts changes publishing schedule for Platts JKM pricing month derivative assessment

Platts, part of S&P Global Commodity Insights, has changed its publishing schedule of the Platts JKM derivative assessment for the pricing month (symbol: LJKMO00) from June 16, 2025.

With immediate effect, the Platts JKM derivative assessment for the pricing month will be published from the first assessment day of a delivery month to the sixth last assessment day of the same delivery month, aligning with the publishing schedule of the JKM balance-month next-day derivative assessment.

For example, Platts will publish the JKM derivative assessment for the pricing month August 2025 from June 16, 2025 to July 8, 2025.

Under the previous publishing schedule, it would run from June 16, 2025, to July 15, 2025 for the pricing month of August 2025.

This change is in line with market feedback and lower trading activity observed in the pricing month derivative contract during the last five assessment days.

To maintain clarity, in the last five assessment days of physical deliveries in the pricing month, Platts will not publish any floating physical bids or offers linked to the pricing month during the APAC physical LNG Market on Close process.
