CME to Launch Treasury Clearing Ahead of SEC Mandate

CME Group will begin cash Treasury clearing on 7 December 2026, 24 days before the US Securities and Exchange Commission's central-clearing requirement takes effect for covered cash Treasury transactions.

The SEC requires direct participants of covered clearing agencies to submit eligible secondary-market Treasury transactions for central clearing from 31 December 2026. The deadline for repo and reverse-repo transactions is 30 June 2027, following a one-year extension granted by the regulator.

CME Securities Clearing received SEC registration in December 2025. Its launch was initially expected in the second quarter of 2026, then moved to the third quarter before CME set the December date.

The new service will process cash securities and repo trades and offer margin offsets across Treasuries, repo and CME interest-rate futures, reducing the need to fund each exposure separately. CME already has a cross-margining arrangement with the Fixed Income Clearing Corporation, allowing eligible Treasury positions cleared at FICC to offset interest-rate futures held at CME. According to the group, the programme currently generates more than $2 billion in daily margin savings. Access was expanded to end-user clients in April 2026 after previously focusing on clearing members' proprietary accounts.

CME Securities Clearing will add another route for recognising offsets within the group's own cash and derivatives infrastructure, with the existing FICC arrangement continuing in parallel. The clearing house will support done-with clearing, where the same intermediary handles execution and clearing, and done-away transactions, where a trade is executed with one counterparty and routed through another clearing agent.

FICC still clears most Treasury and repo activity. ICE Clear Credit became the first alternative provider when its cash Treasury service went live in February. A July FICC survey found that 79% of responding netting members had the required account structures in place. More than $1.2 trillion of daily cash Treasury activity was already being cleared at FICC, with an estimated $300 billion to $400 billion still to migrate. However, the accompanying report said meaningful implementation work remained.

CME Chairman and CEO Terry Duffy pointed to total US federal debt exceeding $40 trillion when describing the scale of the market transition.
