In CBO’s newly published economic projections, higher trade barriers—in particular, increases in tariff rates—implemented by the United States and its trading partners since January 2018 reduce the level of real (that is, inflation-adjusted) U.S. gross domestic product by roughly 0.3 percent by 2020.
If current laws governing federal taxes and spending generally remained in place, the economy would expand by 2.3 percent this year and then grow at an average annual rate of 1.8 percent over the next decade, CBO projects.
