Upgraded their outlooks for this year and next, but see economic trouble around 2020 and after.

The International Monetary Fund has upgraded its economic outlook for the United States in 2018 and foresees a strong year for the global economy as well. The IMF predicted Tuesday that the U.S. economy will grow 2.9 percent this year, up from the 2.7 percent it had forecast in January and from the 2.3 percent growth the economy achieved last year. The U.S. economy will enjoy a boost through 2020 from tax cuts President Donald Trump signed into law in December, the IMF predicts.

The lending agency kept its forecast for worldwide growth this year at 3.9 percent, which would be its fastest pace since 2011. The world's major regions are expanding in unison for the first time in a decade, aided by low interest rates and a revival in global trade.
