How FX Volatility Affects Counterparty Risk in Forward Contracts
Summary
The document distinguishes the market-risk protection provided by an FX forward from the credit exposure that remains before settlement. Fixing an exchange rate can protect a party against adverse currency moves at delivery, but it does not ensure that the counterparty will perform. When the forward has positive value to one side, that side is exposed to the other party’s ability to pay over the contract’s life.
The responses explain that higher exchange-rate volatility can widen the distribution of future forward values and increase the chance of substantial exposure to the party that owes money. A simulated credit exposure profile would therefore incorporate currency volatility. This is a general relationship rather than a quantified result: the document gives no model calibration or specific exposure measure. Actual risk also depends on collateral arrangements and other contract terms, which are not analyzed in detail.
Key ideas
- An FX forward fixes the exchange rate for settlement but does not remove counterparty default risk.
- Counterparty exposure exists when the contract has positive value to one party before maturity.
- Higher FX volatility can widen the distribution of future contract values and increase potential exposure.
- Collateral arrangements affect the practical counterparty risk profile.

# Volatility and Counterparty risk for FX Forward # Volatility and Counterparty risk for FX Forward How does the change in FX volatility affect the counterparty risk of an FX-forward? Should it not be riskless since the forward itself is "protecting" the exchange rate fluctuations? ## Answer by sen_saven (score 2) https://quant.stackexchange.com/a/32983 I think the misunderstanding here is that the 'protection' that the FX Forward offers can turn into a counterparty risk in the end of the day. To put it simply, if you lock for yourself a nice rate and the market moves downwards then are you sure that your counterparty will be able to pay you on the maturity date? ## Answer by cykor21 (score 2) https://quant.stackexchange.com/a/33693 At a general level it is helpful to delineate market (price) risk and counterparty credit risk. And in terms of market risk, the FX forward protects you against unfavourable currency rate move at the delivery date. Counteparty credit risk exists over the life of the contract whenever forward value is positive to your side. And, yes, the higher the currency rate volatilty, the higher the counteparty credit risk should be. If you proceeded to calculate credit risk profile you, then volatility would enter into a simulation model of the currency rate and higher parameter values would result in wider forward value distribution. Intuitively, probability that the contract will be extremely positive to your side is higher when the volatility is higher. In reality things are more complicated when there is collaterisation scheme (as mentioned already), but you asked about a general relationship without further assumptions. ## Answer by rupweb (score 1) https://quant.stackexchange.com/a/32982 Well yeah the whole point of an FX forward is to insure the counterparty from FX and interest rate risk. The future cashflows are fixed whatever the FX and interest rate volatility. However, since no cashflows actually take place until value date then to deal with counterparty risk then collateral is usually required. I think that's going to be a requirement in Mifid II
