U.S., global growth outlooks slashed on tariff impacts

The OECD has significantly lowered its global and U.S. GDP growth forecasts for 2025 and 2026, citing the negative impacts of tariffs, tighter financial conditions, and weakened confidence; global GDP growth is now projected at 2.9% for both years, while U.S. growth is forecast at 1.6% and 1.5% respectively. The report also highlights a heightened risk of persistent inflation, with OECD-wide inflation expected to be 4.2% this year, although the forecast hinges on the uncertain future of current trade barriers, the reversal of which could improve economic prospects.

Analysis

The Organisation for Economic Co-operation and Development (OECD) has significantly revised its economic outlook downwards, reflecting a notably pessimistic stance compared to its cautious assessment three months prior. Global GDP growth forecasts have been reduced to 2.9% for 2025 (from 3.1% projected in March) and to 2.9% for 2026 (from 3.0%). The U.S. outlook is similarly affected, with its growth projections cut to 1.6% for 2025 (revised from a previous forecast of 2.2%) and 1.5% for 2026 (revised from 1.6%). These downgrades are attributed by the OECD to the pervasive impacts of tariffs, tighter financial conditions, weakened business and consumer confidence, and elevated policy uncertainty, which collectively pose substantial risks to growth. Compounding these concerns, the OECD has flagged a heightened risk of persistent inflation, now forecasting OECD-wide inflation for its 38 member countries at 4.2% for the current year, a 0.5 percentage point increase from its outlook six months ago. The forecast's primary uncertainty hinges on the future of trade barriers; the report notes that an early reversal of recent tariffs could materially improve growth prospects and alleviate inflationary pressures. Despite the generally gloomy projections, the OECD still anticipates at least marginal economic expansion in nearly all member countries this year (except Austria) and growth across all members, including Austria, in 2026. The provided signals indicate a strongly negative sentiment (-0.65 score) and a pessimistic tone, with a market impact score of 0.6 suggesting these revisions are likely to weigh on investor sentiment.

Key Decisions for Investors

• Investors should exercise increased caution towards assets highly sensitive to global and U.S. economic growth, given the OECD's significantly downgraded forecasts and the cited macroeconomic headwinds.
• It is crucial to closely monitor developments in international trade policy and tariff rates, as these are identified as key variables that could substantially alter economic prospects and market direction.
• Portfolio strategies should consider the heightened risk of persistent inflation, potentially by evaluating investments in inflation-hedging assets or companies with strong pricing power.
