CME Group will start clearing cash Treasury trades through CME Securities Clearing on December 7, 2026, just 24 days before an SEC mandate forces the same activity through central clearing. The launch adds a new revenue line for CME and extends margin offsets across Treasuries, repo, and its interest-rate futures franchise, putting it in more direct competition with the incumbent clearer, FICC.
CME times launch to the SEC deadline
CME Group set December 7 as the start date for CME Securities Clearing, 24 days ahead of the SEC's central-clearing requirement for covered cash Treasury transactions. The SEC mandate takes effect December 31, 2026 for direct participants of covered clearing agencies. The deadline for repo and reverse-repo transactions was separately pushed to June 30, 2027 after a one-year extension from the regulator.
CME Securities Clearing received SEC registration in December 2025, with its debut then slipping from an initial second-quarter 2026 target to the third quarter, before CME fixed the December date. CME Chairman and CEO Terry Duffy pointed to total US federal debt exceeding $40 trillion when describing the scale of the shift toward central clearing.
New service links Treasuries to futures margin
Beyond processing cash securities and repo trades, the service offers margin offsets across Treasuries, repo, and CME interest-rate futures, cutting the need to fund each exposure separately. CME already runs a cross-margining arrangement with the Fixed Income Clearing Corporation (FICC) that lets eligible Treasury positions cleared at FICC offset interest-rate futures held at CME.
That existing programme generates more than $2 billion in daily margin savings, according to CME Group. Access was widened to end-user clients in April 2026, after previously covering only clearing members' proprietary accounts.
FICC remains the incumbent as competition builds
FICC remains the incumbent by scale, clearing most Treasury and repo activity, while CME Securities Clearing will add another route for recognizing offsets alongside it. ICE Clear Credit became the first alternative provider when its cash Treasury service went live in February.
The new CME service will support done-with clearing, where the same intermediary handles execution and clearing, and done-away clearing, where a trade executed with one counterparty is routed through a separate clearing agent. A July FICC survey found 79% of responding netting members had the required account structures in place. More than $1.2 trillion of daily cash Treasury activity was already cleared at FICC. An estimated $300 billion to $400 billion still remained to migrate. The accompanying report said meaningful implementation work remained.
