President Trump's trade war is causing the global economy to slow, with growth now heading for its weakest pace since the COVID-19 pandemic, the OECD warned on Tuesday. The OECD cut its forecasts for most G20 economies and warned that easing trade tensions is key to boosting investment and keeping prices stable.

Economic growth will slow this year and next as the trade war hampers development in the United States and around the world, the Organization for Economic Cooperation and Development said.

Global economic growth is set to be slower this year largely because of Donald Trump's US tariffs, according to a leading international policy group. Worldwide growth is now expected to slow to a "modest" 2.9%, down from a previous forecast of 3.1%, said the Organization for Economic Co-operation and Development (OECD).
