Exchange-traded vs OTC
Exchange-traded derivatives are standardised contracts that trade on an organised venue (ASX 24, CME, EUREX) with a central counterparty clearing every trade. Over-the-counter (OTC) derivatives are privately negotiated bilateral contracts, customisable in size, tenor, and underlying, but historically exposed to bilateral counterparty risk. Since the G20 Pittsburgh reforms of 2009, standardised OTC products such as plain-vanilla interest rate swaps must be centrally cleared and reported to trade repositories, narrowing the gap between the two segments.
Why it matters
Exchange-traded contracts are like buying a Coke from a vending machine. The product is standard, the price is on a screen, and the machine guarantees delivery once you insert your coin. OTC contracts are like commissioning a tailor. You specify the size, fabric, and finish, you agree a price face-to-face, and you rely on the tailor to deliver. The tailor's reputation matters because if they go bankrupt mid-job you lose the deposit. That trust-based bilateral nature is precisely why OTC trades carry counterparty risk and why the post-GFC reforms pushed standardised OTC into central clearing.
Worked examples
ASX SPI 200 futures versus a bespoke AUD/USD forward. A fund manager wants exposure to the broad Australian equity market through ASX SPI 200 futures, and separately wants to hedge a US$47.3 million receivable due in 89 days through an AUD/USD forward with an investment bank.
The ASX SPI 200 futures trade is exchange-listed, with a standard contract size of A$25 times the index level, fixed quarterly expiry dates, full margining, and novation to ASX Clear (Futures). The AUD/USD forward is OTC. The bank quotes a custom-dated forward for the exact US$47.3 million amount on day 89, settling against an agreed reference rate. The fund manager faces the bank's credit risk, normally mitigated by an ISDA Master Agreement with a Credit Support Annex requiring collateral when mark-to-market crosses a threshold.
Plain-vanilla interest rate swaps post-2009. A USD 5-year fixed-for-floating swap.
The swap is OTC negotiated but centrally cleared through a CCP such as LCH SwapClear or CME. The dealers agree the trade bilaterally, then submit it to the CCP, which novates the contract. Both sides post initial and variation margin to the CCP. Bespoke or exotic OTC products such as a long-dated AUD inflation swap may remain uncleared, subject to higher Basel III capital charges and bilateral margin requirements under the BCBS-IOSCO framework.
Common mistakes
- ✗OTC markets are unregulated. Post-GFC, standardised OTC contracts must be centrally cleared, reported to a trade repository, and uncleared OTC trades face mandatory bilateral margin requirements. ASIC and APRA supervise OTC activity in Australia.
- ✗Exchange-traded means zero default risk. Default risk is massively reduced by novation and daily margining, but a CCP failure is theoretically possible. CCPs themselves are now treated as systemically important financial market infrastructure.
- ✗OTC contracts are always larger than exchange contracts. While bespoke OTC trades can be very large, OTC notional outstanding dwarfs exchange-traded notional largely because of long-dated interest rate swaps, not larger individual deal sizes.
Revision bullets
- •Exchange: standardised, listed, CCP-cleared, transparent
- •OTC: customisable, bilateral, ISDA-documented
- •Futures trade on exchange; forwards and most swaps are OTC
- •G20 Pittsburgh 2009 pushed standardised OTC to central clearing
- •Trade repositories now report OTC trades for transparency
- •ISDA Master Agreement governs bilateral OTC contracts
