Federal Reserve Bank of New York’s John Williams says Treasury central clearing transition is ahead of schedule

The massive plumbing overhaul underneath the US Treasury market is running ahead of schedule, according to Federal Reserve Bank of New York President John Williams. In a statement on September 22, Williams said the industry’s shift to central clearing for Treasury securities and Treasury-collateralized repurchase agreements is outpacing the timeline regulators had set.

The numbers behind the progress

A DTCC survey of FICC Government Securities Division members backs up Williams’ assessment with hard data. An average of over $1.2 trillion in daily Treasury cash activity is already being centrally cleared. That leaves roughly $300-400 billion still needing to migrate before the December 31, 2026 compliance deadline for cash trades.

FICC now clears more than $12 trillion in average daily transactions across cash and repo markets. That represents a 165% increase since the SEC first proposed its clearing mandate.

How we got here

The SEC adopted its Treasury clearing rules back in December 2023, responding to vulnerabilities exposed during periods of market stress. The March 2020 Treasury market seizure, when even the world’s deepest bond market briefly stopped functioning normally, was a major catalyst.

In February 2026, the SEC extended deadlines, pushing the cash clearing requirement to December 31, 2026 and repo clearing to June 30, 2027.

Why this matters for market structure

Central clearing is projected to provide primary dealers with up to an additional $1.3 trillion in repo capacity. That’s new liquidity that didn’t exist under the old bilateral framework.

The repo market deadline of June 30, 2027 still looms, and repo clearing involves different technical challenges than cash clearing. But if the cash side’s trajectory is any indication, the industry appears to have the operational momentum to handle it. Williams’ ahead-of-schedule assessment suggests that the biggest structural reform in Treasury markets since the post-2008 era is landing without the turbulence many had feared.
