Amendment of the Index Spacing Parameter from Static to Dynamic for the CME CF Cryptocurrency Real Time Indices

The Administrator announces the amendment of the Index Spacing Parameter from Static to Dynamic across all CME CF Cryptocurrency Real Time Indices.

This change replaces the current fixed, static value with a dynamically computed value derived from the consolidated order book at each observation.

Currently, Spacing (s) is fixed for each individual CME CF Cryptocurrency Real Time Index, meaning the price-volume (PV) curve is constructed using the same price increments regardless of market conditions. The updated Spacing parameter will be derived dynamically at each Calculation Time and Section 6.2 of the CME CF Real Time Indices Methodology Guide will be updated to reflect this change.

Implementation Timelines
At approximately 11:00 London Time, on June 08th, 2026, the Spacing (s) across all CME CF Cryptocurrency Real Time Indices will be amended to Dynamic.

Digital assets gave back ground over the past week as the Binance hack, not macro, set the tape. Losses were broad, led by exchange-linked and high-beta names, while Hyperliquid stood apart. Defensive factors led, implied volatility repriced higher, CME basis widened and ETH staking rewards spiked.
