According to Reuters, the prospect of a trade war is threatening the global growth outlook, which otherwise is on course for a 40-year low in unemployment, the OECD said on Wednesday.
Global growth is set to nudge up from 3.8 percent this year to 3.9 percent in 2019, the Organization for Economic Cooperation and Development forecast in its biannual Economic Outlook.
The Paris-based policy forum made up mainly of developed countries had in March penciled in an estimate of 3.9 percent for both years but trimmed its outlook for 2018 due to a weak start to the year because of temporary factors like bad weather.
The OECD said budgetary easing had taken over from central bank stimulus as the main motor of global growth with three fourths of its member countries now estimated to be loosening purse-strings, led by massive U.S. tax cuts.
Against that backdrop, the overall OECD unemployment rate was seen falling to five percent by the end of 2019, hitting the lowest level since 1980 and setting the stage for so-far elusive growth in workers' wages.
“In spite of all this good news, risks loom large for the global outlook. What are these risks? First and foremost, an escalation of trade tensions should be avoided,” acting OECD chief economist Alvaro Pereira wrote in an introduction to the organization’s biannual Economic Outlook.
The warning comes as European governments brace for the expiration of temporary exemptions on new U.S. steel and aluminum tariffs on June 1, which has outraged Washington's closest allies.
Though the number of trade restrictions has crept higher over the last decade, further measures could create a significant drag on growth because the global economy is now more interconnected than ever before, the OECD said.
With tax cuts boosting U.S. investment, the world's biggest economy was forecast to grow 2.9 percent this year and 2.8 percent next year.
As a result the Federal Reserve was expected to keep gradually increasing its interest rates, bringing the Fed funds rate to 3.25 percent by the end of 2019.
The euro area economy was seen growing 2.2 percent this year and 2.1 percent in 2019 as the labor market and wages recover. The European Central Bank was seen halting bond purchases this year and increasing its negative deposit rate in the second half of 2019.
Outside the euro area, the OECD marginally raised its outlook for Britain to 1.4 percent growth this year and 1.3 percent in 2019. The Bank of England was expected to only gradually raise interest rates given the uncertainty over Brexit.
Japanese growth was seen at 1.2 percent both this and next year as growing labor shortages force companies to increase business investment and hire more workers.
