What is CCP clearing?

Central counterparties sit at the heart of US financial markets, yet most corporate treasurers never deal with one directly. A central counterparty steps between banks and dealers in a trade and guarantees each side's obligations if the other defaults. After the 2008 financial crisis, US regulators pushed more derivatives and securities transactions through these clearing houses.

That shift is now reaching the short-term cash markets where many treasurers place surplus cash. The SEC's Treasury clearing mandate will bring a large share of US Treasury repo into central clearing by mid-2027. This guide explains what CCP clearing means, how clearing houses manage risk, how centrally cleared repo compares with other secured options, and what the mandate means for corporate cash. It also covers the limitations of central clearing.

What is CCP clearing?

Clearing takes place after a trade is agreed and before it settles. During this stage, each side confirms and manages its obligations. In CCP clearing, a central counterparty steps between the two original parties. It becomes the buyer to every seller and the seller to every buyer, so each firm faces the CCP rather than each other.

This structure replaces many bilateral exposures with a single netted exposure to a closely regulated institution. If one party fails to pay or deliver, the CCP still completes the trade with the other side. The CCP funds this guarantee with collateral and pooled member resources.

Is a clearing house the same as a CCP?

The terms are often used interchangeably, particularly in exchange-traded markets. Strictly, a clearing house is any organization that processes and reconciles trades between parties. A CCP is a clearing house that also takes on counterparty risk and guarantees settlement. Every CCP is a clearing house, but not every clearing house acts as a central counterparty.

How a CCP works

Novation

When a trade is accepted for clearing, the CCP replaces the original contract with two new ones. The seller and the buyer each now hold a contract with the CCP, so neither is exposed to the other. This legal process is called novation.

Multilateral netting

Because every trade shares the same counterparty, the CCP can net each member's positions across all of its trades. If a bank owes $500 million to one member and is owed $450 million by another, it only needs to settle the $50 million difference. Netting reduces the number of settlements and shrinks the exposures carried on bank balance sheets. It also eases banks' regulatory capital requirements, which can support tighter pricing in cleared markets.

Initial and variation margin

Members post initial margin when they open a position, sized to cover potential losses if that member defaults. The CCP then marks positions to market at least daily and collects variation margin from members whose positions have lost value. In repo markets, margin calls can occur several times a day, which keeps losses contained and stops exposures from building unnoticed.

What happens if a clearing member defaults?

Every CCP has a default waterfall, the sequence in which it uses its resources to absorb losses. The defaulting member's own margin and default fund contribution are used first, so the firm that caused the loss pays first. Next, the CCP commits a portion of its own capital, often called skin in the game, which aligns its interests with those of its members.

If losses exceed these layers, the CCP draws on default fund contributions from the surviving members. It can also call for additional contributions and use any remaining capital. This tiered structure is designed to absorb a single member default without disrupting the wider market, although an extreme event could still test it.

CCP clearing in the US

The US hosts several of the world's largest CCPs. The Fixed Income Clearing Corporation (FICC), a subsidiary of DTCC, clears US Treasury cash and repo trades through its Government Securities Division and reports more than $12 trillion in average daily cleared transactions across cash and repo. CME Group and ICE operate major clearing houses for futures, options, and swaps, and the Options Clearing Corporation clears listed equity options.

Who supervises US CCPs?

Oversight in the US is split by product. The Securities and Exchange Commission regulates clearing agencies for securities, including FICC. The Commodity Futures Trading Commission regulates derivatives clearing organizations, such as the futures and swaps clearing houses run by CME and ICE. Under Title VIII of the Dodd-Frank Act, the Financial Stability Oversight Council can designate a CCP as a systemically important financial market utility, which brings additional risk management standards and Federal Reserve involvement in its supervision.

The SEC's Treasury clearing mandate

Concerns about resilience in the US Treasury market, including the March 2020 disruption, led the SEC to adopt new clearing requirements in December 2023. The rule requires direct participants of a covered clearing agency to centrally clear eligible secondary market Treasury transactions. In February 2025, the SEC extended the compliance dates by one year. As of the SEC's August 2026 update, eligible cash transactions must be cleared by December 31, 2026 and eligible repo transactions by June 30, 2027.

FICC and CME Securities Clearing are both approved to clear US Treasuries, giving the market more than one CCP for the first time. Industry groups are still working through open issues such as cross-border and inter-affiliate relief, and SIFMA published a standardized done-away clearing agreement in July 2026 intended to help intermediaries onboard new clients.

How centrally cleared repo compares with bilateral and tri-party repo

In a repo agreement, one party lends cash against collateral and agrees to reverse the trade at a set price and date. Our guide to repurchase agreements explains the mechanics. The key differences between repo types are who you face and how the collateral is managed.

In bilateral repo, the cash lender deals directly with the borrower, and both sides manage the collateral themselves. In tri-party repo, an independent agent holds and administers the collateral. In the US, that agent is typically BNY, which settles the large majority of tri-party repo. The lender still faces a single borrower, but the cash is backed by collateral worth more than the loan.

In centrally cleared repo, counterparty risk moves from the borrower to the CCP. Collateral is still marked to market and margined, and the CCP's default waterfall stands behind the trade. For a cash lender, that means facing one regulated institution and its pooled resources rather than a single bank. The two structures can also be combined: FICC's Sponsored General Collateral service and its Agent Clearing triparty service approved in January 2026 clear trades that settle on BNY's tri-party platform.

Why CCP clearing matters for corporate treasurers

Most corporate treasurers will never become clearing members, and the Treasury clearing mandate does not apply to them directly. Central clearing still shapes their options, because it affects the pricing banks can offer and the forms of security available for surplus cash.

A different source of counterparty risk

An unsecured bank deposit exposes a treasurer to a single bank's credit risk, and FDIC insurance covers only $250,000 per depositor, per insured bank, for each ownership category. For most corporate balances, nearly all of the deposit sits above that limit. Secured lending through repo adds collateral, and central clearing adds a further layer of protection through margin and shared default resources. For organizations with strict counterparty limits, this can widen where cash can be placed without adding single-bank concentration. Our article on why diversification matters for corporate cash explains how these limits shape allocation.

Access has been the barrier

Direct CCP membership is designed for banks and large dealers and comes with demanding capital and operational requirements. Buy-side firms usually reach cleared repo through sponsored models, where a member bank acts as their sponsor. FICC's Sponsored Service has grown quickly ahead of the mandate and now has more than 2,850 sponsored members, according to DTCC's July 2026 survey. Those members are mostly money market funds, asset managers and hedge funds. Only a minority of dealers expect to offer clearing to clients, and access for corporate treasurers has been even more limited.

Accessing cleared repo through TreasurySpring

TreasurySpring has partnered with Eurex Clearing and Clearstream to make centrally cleared repo available to corporate cash investors in USD, EUR, and GDP. Our One+ cash investments are designed to provide access to over-collateralized, centrally cleared euro repo with next-day liquidity. Investors use the same platform as our other FTFs, with no clearing membership or additional operational setup required. Our guide to secured FTFs explains how collateral works across our secured products.

The limits of central clearing

Central clearing reduces counterparty risk, but it does not remove it. Risk concentrates in a small number of CCPs, which makes each one systemically important. Problems at a CCP could spread widely, which is why US regulators require recovery and wind-down plans for designated clearing agencies.

Margin models can also amplify stress, since CCPs may raise requirements during volatile markets, precisely when members have less cash to spare. Cleared repo typically accepts only high-quality government securities and cash as collateral, and clearing carries fees that someone has to pay. Treasurers should weigh these trade-offs against the protection clearing provides.

Putting CCP clearing in context

CCP clearing places a regulated institution between buyers and sellers, supported by margin and a layered default waterfall. It is already central to US derivatives markets, and the SEC's mandate will extend it across much of the Treasury cash and repo market over the coming year.

For treasurers, centrally cleared repo is another option for securing surplus cash, with its own balance of protection and limits. If you would like to understand how centrally cleared repo could fit into your cash strategy, contact our team.
