SUBSCRIBER NOTE: Platts launches new daily, monthly North America natural gas indices

On August 31 2017, S&P Global Platts launched new daily indices as part of an agreement with Intercontinental Exchange to improve natural gas price transparency and bolster North America price benchmarks.

The new daily indices were launched trade date August 31 for gas flow September 1, with the new monthly indices to be launched September 25, the first day of October bidweek.

Platts has launched the new assessments under the following methodology:

1. New Preliminary Daily Indices for Platts Locations:

Platts will publish new preliminary daily price indices for Platts locations shortly after the market close. Only trades executed on the ICE Exchange will be included in the preliminary indices. Both the buy and sell side of ICE trades will be counted in the indices, regardless of whether the counterparties are Platts price reporters. Platts will not screen the trade data for outliers or apply any other methodology beyond deriving a volume-weighted average. The indices will reflect transactions executed between 6:00 am and 1:00 pm CPT. Platts will publish the index price, high price, low price, common range, volume and deal count for each location with trading activity. Price data will not be published for locations with zero transactions. Prices will be published to three decimal places and be rounded to the nearest half cent.

2. New Final Daily Indices for ICE Locations:

Platts will publish final daily indices for ICE locations at the same time preliminary daily indices for Platts locations are published. Only trades executed on the ICE Exchange will be included in the final indices for ICE locations. Both the buy and sell side of ICE trades will be counted in the indices, regardless of whether the counterparties are Platts price reporters.

Platts will not screen the trade data for outliers or apply any other methodology beyond the creation of a volume-weighted average. The indices will reflect transactions executed between 6:00 am and 1:00 pm CPT. Platts will publish the index price, high price, low price, common range, volume, and deal count for each location with trading activity. Price data will not be published for ICE locations with zero transactions. Similar to Platts locations, daily prices for ICE locations will be published to three decimal places and will be rounded to the nearest half cent.
