SUBSCRIBER NOTE: Platts expands use of basis trades in North American gas indices

Following extensive market consultation and feedback, S&P Global Platts has made the following changes regarding the use of spread and basis transactions in its monthly indices:

Platts expanded the use of physical basis trades in monthly indices, in all locations, where the price is expressed as a differential to the NYMEX Henry Hub settlement price. Previously, monthly physical basis trades are only included in Platts locations east of the Rocky Mountains. This change was implemented starting November 26, 2018, for December bidweek. Platts continues not to include physical basis trades in its daily indices.
