Foreign Exchange Swap (FX Swap)
A Foreign Exchange Swap (FX Swap) is a financial derivative contract that combines a spot foreign exchange transaction with a simultaneous forward contract in the opposite direction. It involves two parties agreeing to exchange two currencies at one date and reverse the exchange at a future date, with the forward rate typically differing from the spot rate by the interest rate differential between the two currencies.
Understanding FX swaps
FX swaps are fundamental instruments in the foreign exchange (forex) market, primarily used for liquidity management and hedging purposes. The instrument consists of two legs:
- Near leg (spot transaction): Initial exchange of currencies at the current market rate
- Far leg (forward transaction): Reversal of the exchange at a pre-agreed forward rate
The pricing reflects interest rate differentials between currencies, making FX swaps closely linked to money markets and interest rate markets.

Risk considerations
Market risk
The primary risks in FX swaps include:
- Interest rate movements affecting forward rates
- Currency volatility impacting mark-to-market values
- Credit risk of counterparties
Settlement risk
FX swaps face settlement finality considerations, particularly in cross-border transactions. This risk is often managed through:
- Central clearing mechanisms
- Payment-versus-payment (PvP) settlement
- Netting arrangements
Pricing mechanics
The forward rate in an FX swap is calculated using the following formula:
Forward Rate = Spot Rate × (1 + Interest Rate Currency 1)/(1 + Interest Rate Currency 2)
This relationship, known as covered interest rate parity, ensures no arbitrage opportunities exist between money markets and FX markets.
Market impact
FX swaps can influence:
- Currency market liquidity
- Interest rate differentials
- Cross-border capital flows
The instrument's pricing and execution are subject to market impact models and require sophisticated transaction cost analysis.
Regulatory framework
FX swaps operate under various regulatory requirements:
- Trade reporting obligations
- Clearing requirements (where applicable)
- Risk management standards
- Capital adequacy rules
Modern FX swap markets increasingly rely on electronic trading protocols and automated execution strategies for efficient execution and risk management.
