Global economic growth is expected to take a hit, in part as a result of President Donald Trump’s tariffs, if major nations remain mired in unresolved trade disputes, the Organization for Economic Cooperation and Development said in a report released Tuesday.

President Donald Trump’s trade war will wreak greater economic damage than previously expected, both in the United States and everywhere else, according to new forecasts by the Organisation for Economic Co-operation and Development.

President Donald Trump’s turbulent tariffs are projected to cause a sharper slowdown in economic growth in the U.S. than expected.
