OECD lowers global outlook as Trump trade war hits US growth

The OECD has revised its global economic growth forecast downward, projecting 2.9% growth for both 2025 and 2026, down from previous estimates of 3.1% and 3.0% respectively, citing the escalating U.S. trade war as a primary drag. The U.S. economy is now expected to grow by only 1.6% in 2025 and 1.5% in 2026, a significant cut from prior forecasts, as tariffs squeeze consumer spending and corporate investment; the OECD warns that increased protectionism could further depress growth and fuel inflation, potentially reducing global economic output by 0.3% after two years if tariffs are broadly increased.

Analysis

The Organisation for Economic Cooperation and Development (OECD) has significantly revised its global economic growth forecasts downwards, projecting a slowdown to 2.9% in both 2025 and 2026, a reduction from its March estimate of 3.0% growth for 2025. This dimmer outlook is primarily attributed to the escalating impact of the U.S. administration's trade war. The U.S. economy is expected to bear a substantial brunt, with its growth forecast for 2025 slashed to 1.6% from a previous estimate of 2.2%, and projected at 1.5% for 2026 (down from a prior 1.6% forecast). The OECD attributes this U.S. slowdown to tariffs squeezing consumer purchasing power and policy uncertainty dampening corporate investment, assuming tariffs in place as of mid-May persist through 2026. A stark warning accompanies this outlook: an additional 10 percentage point increase in U.S. bilateral tariffs on all countries could reduce global economic output by approximately 0.3% after two years and fuel inflation. Furthermore, U.S. fiscal health is a concern, with the budget deficit projected to reach 8% of GDP by 2026, driven by extended tax cuts and weaker economic growth. In this environment, the Federal Reserve is anticipated to keep interest rates on hold through the current year before potentially cutting the fed funds rate to a 3.25-3.5% range by the end of 2026. Conversely, China's economy is forecast to grow 4.7% in 2025 and 4.3% in 2026, partially insulated by government stimulus, while the Euro area's growth is projected at a stable 1.0% in 2025 and 1.2% in 2026. The overall sentiment reflected in these revisions, rated as moderately negative, underscores increased global economic fragility.

Key Decisions for Investors

• Investors should exercise increased caution with assets highly sensitive to global economic growth, particularly those with significant exposure to the U.S. market, given the OECD's downward revisions and the pronounced U.S. slowdown.
• Closely monitor developments in U.S. trade policy and any new tariff implementations, as these are identified as primary risks to global growth and potential catalysts for heightened market volatility.
• Consider implementing defensive portfolio adjustments or hedging strategies to mitigate risks associated with potential stagflationary pressures stemming from increased tariffs and slowing economic activity, especially in the U.S.
• Evaluate geographic allocations, as the OECD projects relative resilience in China and stability in the Eurozone compared to the U.S., which may present diversification opportunities.
• Factor in the potential for U.S. Federal Reserve interest rate cuts towards the end of 2026, which could significantly influence fixed income valuations and currency market dynamics, warranting adjustments to interest-rate-sensitive positions.
