The price of foreign currencies. If it costs $.42 to buy one Swiss Franc, the exchange rate is .4200. As one currency is inflated faster or slower than the other, the exchange rate will change, reflecting the change in relative value. The currency being inflated faster is said to be becoming weaker because more of it must be exchanged for the same amount of the other currency. As a currency becomes weaker, exports are encouraged because others can buy more with their relatively stronger currencies. The CENTER ONLINE Futures Glossary
