LCH is a clearing group within London Stock Exchange Group (LSEG). Its operating central counterparties, LCH Ltd in the United Kingdom and LCH SA in France, clear eligible transactions across several markets. Older contracts, filings, and articles may use the former name LCH.Clearnet; current official materials use LCH and identify the specific legal clearinghouse and service.
Key Takeaways
- LCH is a group and service brand, not one undifferentiated legal counterparty.
- LCH Ltd and LCH SA are separate clearinghouse entities with different locations, regulators, rulebooks, memberships, and service scopes.
- SwapClear, RepoClear, ForexClear, EquityClear, CDSClear, and other names identify clearing services rather than exchanges.
- The legal entity and service determine margin, collateral, default-fund, segregation, settlement, and recovery rules.
- Clearing through LCH can provide netting and standardized risk controls but does not eliminate market or liquidity risk.
- Current LSEG pages and rulebooks should replace historical LCH.Clearnet descriptions in operational analysis.
LCH Group Structure
The official LCH clearinghouse overview identifies two operating clearinghouses:
| Entity | Location and role | Examples of services identified by LSEG |
|---|
| LCH Ltd | UK-registered central counterparty | SwapClear, ForexClear, RepoClear, EquityClear, and listed-rates clearing |
| LCH SA | France-based central counterparty | CDSClear, RepoClear, fixed-income, and digital-asset clearing services |
Product eligibility and legal scope can change. The current rulebook, service procedures, and entity documentation control; a brand-level description is not enough for a trade, collateral, or default analysis.
Major Clearing Services
| Service | Broad market function | What to verify |
|---|
| SwapClear | Eligible over-the-counter interest-rate derivatives | Currency, product, client category, legal entity, and margin model |
| RepoClear | Eligible repos, government debt, and fixed-income transactions | Market segment, settlement venue, sponsored access, and netting rules |
| ForexClear | Eligible deliverable and non-deliverable foreign-exchange products | Product type, currencies, settlement, and clearing mandate |
| EquityClear | Eligible cash equities, equity equivalents, or related products | Trading venue, interoperability, settlement market, and entity |
| CDSClear | Eligible credit-default swaps and related credit products | Reference entity, product eligibility, membership, and legal entity |
| Listed rates | Eligible exchange-traded rates products | Contract, venue, clearing route, and cross-margin eligibility |
The current LCH services page should be used for the active service list. Not every product is available through both LCH Ltd and LCH SA.
How an LCH-Cleared Trade Works
- Eligible counterparties execute a trade through a supported venue or workflow.
- The trade is submitted to the applicable LCH service.
- The specific LCH legal entity accepts the transaction under its rulebook.
- The CCP becomes counterparty to the relevant clearing members.
- Positions are valued and eligible offsets are recognized under the service’s netting and margin methodology.
- Members meet variation-margin, initial-margin, collateral, settlement, and default-fund obligations.
- The service manages maturity, compression, settlement, transfer, or default events under its procedures.
Clients commonly access the CCP through clearing members. The clearing member, account type, and segregation model affect collateral and portability rights.
Worked Example: Offsetting Swap Risk
Assume a dealer clears two eligible interest-rate swaps through the same LCH service:
- pay fixed on USD 100 million of notional; and
- receive fixed on USD 70 million with closely matching terms.
The gross notional is USD 170 million, while the simple directional difference is USD 30 million. The service may recognize risk offsets when calculating portfolio exposure and margin.
Margin is not calculated by applying a flat percentage to USD 30 million. Differences in maturity, fixed rate, floating index, curve exposure, collateral, concentration, and stress behavior remain relevant. If the trades sit in different legal entities, services, accounts, or ineligible netting sets, the expected offset can also be unavailable.
Why the Legal Entity Matters
Writing only “cleared at LCH” can omit facts needed for legal and risk analysis. LCH Ltd and LCH SA operate under different supervisory frameworks and maintain separate rulebooks. Entity identification affects:
- governing law and regulatory authority;
- clearing membership and client-access route;
- default fund and default waterfall;
- eligible products and collateral;
- account segregation and porting;
- settlement systems and currencies; and
- recovery and resolution arrangements.
LSEG’s company-structure page summarizes the entities and regulators. Legal conclusions should be drawn from the current rulebook and transaction documents, not the marketing summary.
Risks and Limitations
- Margin liquidity: Variation and initial-margin calls can increase sharply during volatile markets.
- Model risk: Portfolio offsets and margin depend on risk assumptions, historical data, stress design, and concentration controls.
- Member default: The CCP may need to hedge or auction a large portfolio in an illiquid market.
- Operational dependency: Members depend on clearing, payment, collateral, messaging, and settlement systems.
- Legal fragmentation: Rights can differ by entity, service, account, and jurisdiction.
- Concentration: A major clearing service can become a systemically important point of dependency.
- Rule change: Product scope, collateral, fees, margin, and default procedures can change.
How to Review an LCH Reference
- Replace the former LCH.Clearnet label with the current name when appropriate, while preserving it in historical quotations or document titles.
- Identify LCH Ltd or LCH SA.
- Name the service and eligible product.
- Determine the clearing member, client status, and account-segregation model.
- Review the current general regulations, service procedures, default rules, and collateral provisions.
- Verify settlement venue, currency, margin methodology, and netting set.
- Date-stamp the rulebook version used in a legal, operational, or risk decision.

FAQs
Is LCH.Clearnet still the current name?
LCH.Clearnet is a former name that remains common in historical materials. Current LSEG materials use LCH and identify the operating clearinghouses as LCH Ltd and LCH SA.
Is LCH an exchange?
No. LCH operates central-counterparty clearing services. Trades can originate on supported exchanges, platforms, or eligible over-the-counter workflows before being submitted for clearing.
Does clearing two trades at LCH guarantee a margin offset?
No. An offset depends on the legal entity, service, account, product eligibility, netting set, portfolio risk, and current margin methodology.
