Protection from foreign currency risk is the quasi-forward purchase of foreign currency which gives you the option of contracting the purchase of foreign currency on a specific date in the future, according to a pre-agreed price and in a pre-agreed amount.
This means that you pay the agreed amount in RSD funds onto at the account held with the bank on the contracted transaction date. This same day, the bank will transfer these funds into a term deposit account. This means that you have a guaranteed fixed FX rate on the contracted transaction date set for you to purchase foreign currency in the future.
