TRACE Affiliate Reporting Rule

MARKETAXESS HOLDINGS INC · 2026-08-07 · Importance 44 · Surprise 60 · In source text

In July 2026, the SEC approved a FINRA proposal requiring member firms to identify and flag certain affiliate back-to-back trade reports in TRACE. FINRA will provide at least 12 months’ notice before mandatory implementation, while voluntary compliance is permitted earlier. Once implemented, qualifying affiliate principal transactions will be excluded from reported monthly TRACE volumes, potentially affecting MarketAxess’s estimated market share for U.S. high-grade, U.S. high-yield and U.S. Treasury products.
