SUBSCRIBER NOTE: Platts to change US crude ANS differential basis to NYMEX CMA

Houston (Platts)--21Jun2018/1235 pm EDT/1635 GMT S&P Global Platts will change the underlying basis reflected in its assessment of the differential for the US crude Alaska North Slope to the NYMEX WTI light sweet crude oil futures calendar-month average, with effect from July 10, 2018.

The differential for ANS is currently assessed basis cash WTI CMA.

This decision follows a May 25 subscriber note proposing the change, which will take effect when Platts begins assessing September as the front month for ANS delivered into the US West Coast.

This change will more closely reflect the way ANS crude is traded in the spot market. The change will not impact the outright price assessment or its value.

Platts will standardize the name of its ANS differential assessment across all publications and on Platts Global Alert. The new name will be "ANS vs NYMEX WTI CMA."

The ANS differential is published under the code AAGWX00. This assessment appears on Platts Global Alert pages 210 and 214, and in the Crude Oil Marketwire, North American Crude and Products Scan, Oilgram Price Report and Latin American Wire publications.
