Liquidity matters


ICE Euribor futures market share
  • Open interest: 92%
  • Volume in 2025: 93%
  • Top of book score ratio: 96%
ICE ESTR futures market share
  • Open interest: 66%
  • Volume in 2025: 53%
  • Top of book score ratio: 79%

ICE evaluates top of book (TOB) quality by analyzing the total size available at the best bid and offer relative to the tick width. A tighter top of book reflects a more liquid market, with deeper size and narrower spreads. As an example, ICE tracks Euribor liquidity by monitoring the front eight contracts at five-minute intervals.

This method captures both quoted sizes and spread widths throughout the trading day, providing a consistent view of market conditions. The resulting ratio allows for comparison of TOB quality across exchanges, helping identify where liquidity is strongest and pricing is most competitive.
