Platts, part of S&P Global Commodity Insights, is proposing new JKM price differential assessments for the spread between JKM derivatives and half-month assessments at the close of Asia-Pacific markets, 4:30 pm Singapore time, effective Jan. 16, 2026.
This follows industry feedback regarding the use of JKM derivatives as a key pricing basis for trading LNG cargoes in the Asia-Pacific region.
The new assessments would include:
- The price difference between the first JKM half-month assessment <AAPSU00> and the JKM balance-month derivative <LJKMB00>
- The price difference between the second JKM half-month assessment <AAPSV00> and the JKM balance-month derivative <LJKMB00>
- The price difference between the third JKM half-month assessment <AAPSW00> and the JKM balance-month derivative <LJKMB00>
- The price difference between the fourth JKM half-month assessment <AAPSX00> and the JKM balance-month derivative <LJKMB00>
- The price difference between the first JKM half-month assessment <AAPSU00> and the M+1 JKM derivative <LJKMO00>
- The price difference between the second JKM half-month assessment <AAPSV00> and the M+1 JKM derivative <LJKMO01>
- The price difference between the third JKM half-month assessment <AAPSW00> and the M+1 JKM derivative <LJKMO01>
- The price difference between the fourth JKM half-month assessment <AAPSX00> and the M+1 JKM derivative <LJKMO01>
- The price difference between the third JKM half-month assessment <AAPSW00> and the M+2 JKM derivative <LJKMO02>
- The price difference between the fourth JKM half-month assessment <AAPSX00> and the M+2 JKM derivative <LJKMO02>
Furthermore, Platts is proposing to publish price differentials between JKM forwards and JKM derivatives, as well as between JKM forwards and half-month assessments:
- The price difference between the JKM M+1 derivative <LJKMO01> and JKM forward M1 <ALJKA00>
- The price difference between the JKM M+2 derivative <LJKMO02> and JKM forward M2 <ALJKB00>
- The price difference between the first JKM half-month assessment <AAPSU00> and JKM forward M1 <ALJKA00>
- The price difference between the second JKM half-month assessment <AAPSV00> and JKM forward M1 <ALJKA00>
- The price difference between the third JKM half-month assessment <AAPSW00> and JKM forward M1 <ALJKA00>
- The price difference between the fourth JKM half-month assessment <AAPSX00> and JKM forward M1 <ALJKA00>
- The price difference between the first JKM half-month assessment <AAPSU00> and JKM forward M2 <ALJKB00>
- The price difference between the second JKM half-month assessment <AAPSV00> and JKM forward M2 <ALJKB00>
- The price difference between the third JKM half-month assessment <AAPSW00> and JKM forward M2 <ALJKB00>
- The price difference between the fourth JKM half-month assessment <AAPSX00> and JKM forward M2 <ALJKB00>
