Financial derivatives exist in two broad structural categories: Over-the-Counter (OTC) instruments, negotiated bilaterally between two parties with bespoke terms; and exchange-traded instruments, standardised contracts traded on a regulated exchange. The distinction has profound implications for pricing, transparency, counterparty risk, margin, and regulatory treatment.
Exchange-traded derivatives
Exchange-traded derivatives are standardised contracts: fixed underlying, fixed notional, fixed expiry dates, fixed settlement terms. They trade on regulated exchanges (CME, ICE, Eurex, NYSE) through a central limit order book or other exchange mechanism. All trades clear through the exchange's affiliated clearing house (e.g. LCH, CME Clearing), which becomes the counterparty to every trade — eliminating bilateral counterparty risk.
Price transparency is complete: the exchange publishes real-time bid, offer, and last-traded prices. Margin requirements are standardised and published — every participant pays the same initial margin for the same contract. Settlement and processing are highly automated.
Exchange-traded derivatives include: equity index futures (FTSE 100, S&P 500, EURO STOXX 50 futures); interest rate futures (Euribor futures, Short Sterling futures); commodity futures; listed equity options.
OTC derivatives
OTC derivatives are negotiated directly between two counterparties — terms are flexible and bespoke. A 10-year interest rate swap can be for any notional, any effective date, any fixed rate, any payment frequency, any day count convention. This flexibility makes OTC derivatives essential for tailored hedging.
The cost of flexibility is complexity: OTC trades require bilateral legal agreements (ISDA), individual counterparty credit risk management (since there is no central clearing house unless voluntarily clearing), complex confirmation and lifecycle management, and — for uncleared trades — bilateral margin under CSAs.
The mandatory clearing mandate
Post-2008, regulators implemented mandatory central clearing for certain standardised OTC derivatives under EMIR (EU/UK) and Dodd-Frank (US). Vanilla interest rate swaps (IRS, OIS) in major currencies, and certain CDS indices, must be cleared through CCPs. Mandatory clearing moves these instruments closer to exchange-traded structures: they retain their OTC terms flexibility but gain the counterparty risk protection of CCP clearing.
The residual bilateral market
Complex, bespoke derivatives — long-dated exotics, structured derivatives with non-standard terms, illiquid reference assets — remain bilateral OTC and cannot currently be cleared. These trades require the full bilateral framework: ISDA documents, bilateral credit risk, UMR initial margin, and ongoing reconciliation. The margin cost of bilateral uncleared trades is a significant commercial factor, and mandates for wider clearing coverage continue to expand.
