Just because a manufacturer only deals in contracts paid in U.S dollars, that doesn't mean it is immune to foreign exchange risk. For example, a firm's supply chain may have a manufacturer buying vehicle fleets from Japan, steel from India, or oil and gas from Russia. Even if the contract includes language that payment will be made in U.S. dollars, the actual pricing calculation component will stem from the underlying value of currencies in Japan, India or Russia. A close evaluation of supply chain contracts with business partners in foreign lands can minimize currency risk.
