The OECD forecasts U.S. economic growth will slow to 1.6% this year due to President Trump’s tariffs, reaching just 1.5% in 2026. Global growth is also predicted to decelerate, hampered by trade uncertainty and policy shifts.

• Trump’s tariffs are the highest since 1938.
• China’s growth will also slow to 4.3% by 2026.
• Eurozone growth is expected to modestly improve.
