From the Summary: "The U.S. merchandise trade deficit is a part of the overall U.S. balance of payments, a summary statement of all economic transactions between the residents of the United States and the rest of the world, during a given period of time. Some Members of Congress and other observers have grown concerned over the magnitude of the growing U.S. merchandise trade deficit and the associated increase in U.S. dollar-denominated assets owned by foreigners. This report provides an overview of the U.S. balance of payments, an explanation of the broader role of capital flows in the U.S. economy, an explanation of how the country finances its trade deficit or a trade surplus, and the implications for Congress and the country of the large inflows of capital from abroad. […] This report will be updated as events warrant."
