A USDA report highlights a decline in the United States' global export leadership in corn, cotton, and tree nuts due to increased competition from countries like Brazil, Argentina, the EU, and Australia. The report points out that the absence of new U.S. free trade agreements between 2012 and 2020 has limited export opportunities in emerging markets. Brazil's potential to become the world's leading corn exporter, alongside its increased dominance in soybean oilseed and cotton markets, is noted. The report also acknowledges the EU, Russia, and Ukraine's role in reducing U.S. wheat exports.
