Background
In December 2023, the Commission adopted rule changes designed to protect investors, reduce risk, and increase operational efficiency by requiring covered clearing agencies to maintain written policies and procedures that are reasonably designed to require their direct participants to centrally clear all “eligible secondary market transactions” in U.S. Treasury securities to which they are a counterparty.

Market participants can contact staff in the Division of Trading and Markets to discuss issues identified during implementation.

The Commission has extended the original compliance dates for these rules by one year to Dec. 31, 2026, for eligible cash market transactions and June 30, 2027, for eligible repo market transactions.
SEC Commissioner Mark Uyeda issued an update on the implementation of rules for the clearing of U.S. Treasury securities noting that "changes to the U.S. Treasury market must be done carefully and deliberatively to avoid disruption.
