Platts will expand the standard LNG cargo vessel size range for JKM, WIM, SEAM, and MEM price assessments to 135,000 to 180,000 cubic meters beginning October 16, 2026. This adjustment aligns assessments with evolving industry fleet standards and reported market offers.
Why it matters
The change reflects the increasing deployment of larger LNG carriers in the global fleet and incorporates industry feedback to better mirror current trade practices. Updating these benchmarks ensures that price assessments remain an accurate reflection of standard market operations.
The new standard capacity range increases the upper limit to 180,000 cubic meters from the previous 175,000 cubic meters. Data collected between January and June 2026 showed that two-thirds of observed offers already operated within this larger capacity range.
The players
Platts
Platts is a leading global provider of energy and commodities information and benchmark price assessments.
The details
The update applies to JKM, WIM, SEAM, and MEM assessments for liquefied natural gas. Moving forward, market participants are expected to accept vessels within this new 135,000 to 180,000 cubic meter range provided they are operationally suitable for the designated ports.
Timeline
January through June 2026: Two-thirds of offers in the Platts assessment process used the 135,000-180,000 cubic meter range.
October 16, 2026: The new standard vessel size range becomes effective for all applicable assessments.
Market Landscape
This policy adjustment aligns with the broader industry transition toward higher-capacity transport to optimize global liquefied natural gas delivery costs. By formalizing these size standards, Platts is updating its benchmarks to remain reflective of the current shipping reality.
For participants in the LNG market, this change means that larger vessels will now be considered the standard for pricing, potentially improving cargo logistics for suppliers and buyers. Traders should prepare for the October 16 implementation when negotiating contracts that rely on these benchmarks.
The takeaway
As vessel technology continues to evolve, market benchmarks must adapt to ensure pricing remains representative of daily transactions. Industry participants should monitor these standard changes to maintain consistency in their own supply chain and pricing models.
