Exchange rate movements influence U.S. export competitiveness
Agricultural goods can be broken into distinct categories based on value or level of processing. Bulk goods, like grains and oilseeds, are sold in large quantities at relatively low per unit costs. They also tend to be relatively standardized products. U.S. and foreign products in these categories are more readily substituted for each other, as changes in exchange rates alter relative prices among suppliers. Higher value goods, like meats, fruits and vegetables, and processed goods, are differentiated by factors such as brand, quality, or sanitary and phytosanitary standards. As a result, they may be less likely to be substituted across origins on the basis of price or relative price in the case of exchange rates. The U.S. trade weighted exchange rate index from the Federal Reserve Bank of Saint Louis has shown strong dollar appreciation since 2014, resulting in declining exports for both categories (bulk exports declined by 9 percent and high-value products fell by 10 percent). Typically, bulk goods would decline further than high-value goods during appreciation, but the 2012-13 U.S. drought had a significant impact on the supply of several major crops. As a result, export volume decreased, but value remained high because of higher commodity prices. By 2014, production of key bulk commodities like corn and soybeans recovered and have since continued to grow, drawing down prices. As prices have fallen and stocks have been replenished, export volume has increased, dulling the perceived impact of a rising dollar.
