As noted earlier, a change in the exchange rate can, in the short run, affect the demand for and supply of commodities, and the competitiveness of US agriculture. When the US dollar strengthens or gains in value, it causes importers to pay more for the US dollar to buy US commodities.
The exchange rate is important because it allows for the conversion of one country's currency into that of another, thereby facilitating international trade for purchases of goods and services and/or transfer of funds between countries, and it allows price comparison of similar goods in different countries.owever, when the US dollar is strong, US businesses and consumers can purchase foreign goods and services at cheaper exchange rates (e.g., US$1 = 104 yen). This encourages foreign imports because US importers can pass on some of the cost savings to US consumers in the form of lower prices.
