Consultation Conclusion Announcement: CMBI Ethereum Staking Index-Pectra Upgrade

Coin Metrics announced today the conclusion of the market consultation regarding the proposed update to the CMBI Ethereum Staking Index methodology in response to the Ethereum Pectra upgrade.

Following the consultation period, which closed on May 16, 2025, Coin Metrics received no material objections or feedback from market participants.   This absence of response is interpreted as a general consensus and confidence in the proposed methodology adjustment.  

As previously outlined, the Pectra upgrade introduces auto-compounding for Ethereum Staking. To reflect this enhancement, and ensure index represents the performance an investor would expect from purchasing and staking Ethereum,  Coin Metrics will implement the following change:

The calculation input for the CMBI Ethereum Staking Index will transition from using the StakingRate to an hourly converted rate of the Nominal Staking APY (StakingAPYNominal). This adjustment allows the index to properly account for the compounding effect introduced by the Pectra upgrade.

This methodology update will take effect beginning with the June 2025 index rebalancing. The updated calculation approach is detailed in the consultation document  HERE
