Announcement of a Consultation on Changes to CF Rolling CME Futures Index Methodologies

The Administrator announces a Consultation on proposed changes to the index methodologies of the indices below:

The Administrator proposes changes relating only to Sections 4.2 and 7.1 of both methodologies as outlined below:

7.1 General Parameters

The proposed methodology changes mean that product providers replicating or utilizing the CF Rolling CME Bitcoin Futures Index and/or the CF Rolling CME Ether Futures Index may need to factor the changes into their processes and products when transacting in instruments linked to these indices. The financial value of contracts, instruments and funds that directly reference or are settled using these indices may be impacted by the proposed changes.

Implementation Timelines

The Administrator proposes to implement the proposed changes to the CF Rolling CME Bitcoin Futures Index and CF Rolling CME Ether Futures Index methodologies at approximately 11:00 London Time on March 18th, 2025; meaning that both indices will begin to reflect the changes described above from that date forward.

Consultation Process

The Consultation will begin on February 19th, 2025, and end on February 26th, 2025, at 16:00 London Time. Any responses will be treated confidentially, in accordance with the Administrator’s policies and procedures, and will be overseen by the CF Oversight Function, in accordance with the Administrator’s Consultation Process and Procedures.

In case of questions or queries, please do not hesitate to contact [email protected]. 

Any user wishing to file a complaint regarding this Consultation Process can do so confidentially by writing to [email protected].

The market rebounded +16.2% after six consecutive weekly declines, but participation stayed uneven. Liquidity led the non-market factors at +2.2%, while Downside Beta fell -2.2% and Size lost -1.5%, favoring higher-risk and larger-cap exposure over a clean broadening of the rally.
