Platts proposes to launch new price spreads for JKM, WIM, SEAM and TTF assessments

Platts, part of S&P Global Energy, proposes to launch new JKM price differential assessments for the spread between JKM derivatives and other regional cargo and derivatives assessments at the close of Asia-Pacific markets at 4:30 pm Singapore time, effective Aug. 27.
