"Brazil is in the midst of deepening economic and political crises that are closely intertwined and unlikely to be resolved quickly. Given that Brazil is the world's 9th-largest economy and the 12th-largest U.S. trading partner, the country's deteriorating situation could impact U.S. businesses. The crises could also hinder Brazil's response to the Zika outbreak, its preparations for hosting the 2016 Summer Olympics in August, and its ability to address foreign policy concerns, such as stability in neighboring Venezuela."
