Central Counterparties and Novation
A CCP steps into the middle of every cleared trade so that neither original party ever has to trust the other again — the mechanism that does it, novation, is what makes modern derivatives and repo markets survivable when a large member fails.
Two banks agree an interest rate swap. Bank A now cares, for the next ten years, whether Bank B can still pay. If Bank B goes bankrupt in year six, Bank A is an unsecured creditor standing in line with everyone else. Multiply that by every dealer trading with every other dealer, thousands of bilateral threads, and a single large failure can freeze the whole web — which is close to what happened when Lehman Brothers collapsed in 2008 and nobody knew who was exposed to whom.
A central counterparty, or CCP, exists to cut that web apart. When a trade is submitted for clearing, the CCP performs novation: the original contract between A and B is legally torn up and replaced with two new ones — A now faces the CCP, and the CCP faces B. Neither original party has a contract with the other anymore.
Novation replaces one bilateral trade with two trades against a single, heavily collateralised middleman. The buyer no longer needs to know or trust the seller — only the CCP.
Why swapping one counterparty for another helps
It looks like nothing has changed — A and B still have offsetting exposure to someone. The difference is who that someone is. The CCP:
- Is a member of the market for exactly this purpose, capitalised and regulated to survive individual member defaults.
- Collects margin from every member, every day, so its own exposure to any one firm is collateralised in near-real time (see Initial Margin and Variation Margin at a CCP).
- Multilaterally nets exposures. If A owes the CCP on one cleared trade and is owed on another, the CCP can net those into a single number instead of two separate uncollateralised threads.
- Stands behind a default with a pre-funded waterfall of resources — its own capital, then a mutualised default fund contributed by all members — rather than leaving A to sue B's estate (see CCP Recovery, Resolution and Skin in the Game).
The effect is that a member's failure is contained and absorbed by the system that was built for it, instead of cascading unpredictably through whoever happened to be on the other side of that member's trades.
What actually gets cleared
| Product class | Typical CCP | Cleared since |
|---|---|---|
| Listed equity options and futures | OCC, CME, Eurex | Decades — the original use case |
| Interest rate swaps (major currencies) | LCH SwapClear | Mandatory since ~2013 post-crisis reform |
| Credit default swap indices | ICE Clear Credit | Mandatory since ~2013 |
| Repo (US Treasury) | FICC | Long-standing, expanding under 2024 SEC mandate |
| Cash equities | DTCC (NSCC) | Standard for US equity settlement |
Not everything clears. Bespoke, illiquid, or highly structured derivatives often stay bilateral because a CCP will only take on a trade it can risk-manage and, in a default, actually re-hedge or auction off to other members.
A common confusion is treating "cleared" as a synonym for "riskless." Clearing does not remove counterparty risk — it concentrates and collateralises it in one place. The CCP itself becomes a systemically important node, which is precisely why regulators scrutinise CCP risk management as closely as they once scrutinised individual dealers.
Access to a CCP is normally restricted to clearing members — well-capitalised banks and broker-dealers who meet the CCP's financial and operational requirements. A trading firm without membership clears through one of them, a relationship covered in Clearing Members and Client Clearing.
