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.
Key facts
- In July 2026, the SEC approved a proposed rule submitted by FINRA that will require member firms to identify and flag certain affiliate back-to-back trade reports in TRACE, and FINRA stated it will provide at least 12 months prior notice before implementation but will permit voluntary early compliance. source
- When the TRACE affiliate flagging rule is fully implemented, it will suppress qualifying affiliate principal transactions from reported monthly TRACE volumes and could affect the Company’s estimated market share for U.S. high-grade, U.S. high-yield and U.S. Treasury products. source
