Foreign Exchange Markets and Currency Forwards › Limitations and Considerations

Currency forward hedging, while powerful, comes with important limitations that practitioners must understand.

Hedging eliminates both downside and upside. A fully hedged position cannot benefit from favorable currency movements. If you believe you have skill in forecasting currencies, or if you simply want exposure to currency as an asset class, full hedging may not be appropriate. The decision to hedge involves balancing risk reduction against the cost of forgone potential gains and the direct costs of implementing the hedge.

Forward hedging addresses transaction risk but not economic risk. If you are a manufacturer with ongoing foreign currency revenues, you face economic exposure that simple forward contracts cannot fully address. If EUR/USD moves permanently lower, the company's competitive position changes in ways that one-year rolling forwards cannot hedge. Managing economic exposure often requires operational changes, such as relocating production, adjusting pricing, or sourcing inputs differently, rather than purely financial hedges.

Counterparty risk exists in OTC markets. Unlike exchange-traded futures, currency forwards are bilateral OTC contracts. If your counterparty defaults, you may be left unhedged at the worst possible time (when markets have moved against your counterparty). Post-2008 reforms requiring central clearing and margin for many derivatives have reduced but not eliminated this risk.

Rolling hedges can be expensive in certain rate environments. When interest rate differentials are large and persistent, the cumulative cost of rolling forward hedges can significantly erode returns. If you hedge exposure to a high-yielding emerging market currency, you might pay 5-10% annually in roll costs, fundamentally changing the risk-return profile of the investment.
