From the Document: "The U.S. economy, which outperformed other developed economies in 2018 with an estimated 2.9% rate of growth, is projected by the OECD [Organization for Economic Co-operation and Development] and the IMF [International Monetary Fund] to experience a slower growth in 2019 and 2020. Similarly, the Federal Reserve forecasted in March 20, 2019, the U.S. economy would grow by 2.1% in 2019, down from a previous forecast of 2.3%. Some economic indicators suggest the U.S. economy remains comparatively strong, but a deterioration in the economies of major trading partners could negatively affect the U.S. economy and alter these forecasts. Broad financial and economic linkages tie the U.S. and global economies, which means the United States affects and is affected by events in the global economy. These effects are reflected in capital flows, the international exchange value of the dollar, interest rates, and U.S. trade balances."
