How Argus assesses natural gas markets
-
Volume-weighted index method
Each index is a volume-weighted average, calculated from trade price and volume data submitted voluntarily by market participants. Editors review trade data to ensure it aligns with the methodology. -
Bid week index methodology
Bid week indexes are calculated from fixed and basis trades conducted during the final trading week before the start of the contract month. -
Assessment of illiquid markets
Where no trades are reported, Argus publishes a price assessment, clearly identified as distinct from a volume-weighted index. -
Annual compliance audit
Argus natural gas indexes are audited annually by a compliance officer. The methodology has been approved by FERC.
