Platts proposes monthly natural gas trading hours during bidweek and later publication time for preliminary monthly prices

Platts, part of S&P Global Commodity Insights, is proposing to implement trading hours for North American natural gas during the three-day bidweek period and to publish the preliminary monthly prices about one hour later.

At present, trades are accepted at any time on days one and two of bidweek, and until 3:00 pm CT on day three. Platts proposes to establish trading windows from 6:00 am to 4:00 pm CT on each day of bidweek.

Platts also proposes to change the publication time of preliminary monthly prices. The current practice is to publish preliminary monthly prices at approximately 4:00 pm each day of bidweek. Platts is proposing to delay publication of preliminary monthly prices by approximately one hour to include trades completed up to the proposed 4:00 pm cutoff time.

These changes would go into effect on Nov. 21, 2025, commencing with December bidweek.
