The Commodity Futures Trading Commission has issued a request for comment on two developments in energy derivatives markets: extending standard futures contracts to 24/7 trading and listing perpetual contracts that reference physically delivered or storable energy commodities such as crude oil. The agency said it is building a data-driven record to assess the implications of longer trading hours and new contract structures while preserving protections against manipulation and market disruption. The request is split into two sets of questions. One focuses on standard futures contracts, including energy futures, that could move to a 24/7 trading schedule while retaining fixed expiration, including the implications of any material economic changes to delivery or settlement terms. The other focuses on perpetual contracts when they reference physically delivered or storable energy commodities. The Commission said it will use the comments to inform its understanding of these market developments. Written comments are due within 30 days of publication of the request for comment in the Federal Register.
