A forward contract does not “save” money by beating the market; it saves money by removing uncertainty. It allows you to lock in an exchange rate today for a payment you need to make in the future. This means that even if the currency market crashes before your invoice is due, your cost is already fixed at the agreed rate, protecting your profit margins from volatility.
However, it’s important to note,, if the market moves in your favour before settlement, you remain obligated to transact at the agreed rate and will not benefit from the improvement.
