PARIS, FRANCE / RankWire.AI / – In its latest assessment released from Paris in 2026, the OECD has increased its forecast for worldwide economic expansion in 2026 to 2.9%. This upgrade reflects a more robust global economy than previously anticipated. The organization’s projection for 2027, however, was slightly revised downward from 3.1% to 3.0%. Continued investment in artificial intelligence has played a significant role in bolstering trade and economic activity, although persistent inflation and rising energy prices remain considerable challenges for households and businesses across major economies.
Despite performing better than earlier estimates, global growth experienced a slowdown during the first half of 2026. The annualized growth rate dropped to 2.6%, compared to 3.6% in the latter half of 2025. Disruptions in energy markets were cushioned by increased oil inventories and higher production outside the Gulf region. Additionally, alternative supply routes helped maintain fuel flow to global markets. Weaker oil demand from China also contributed to offsetting pressures, as countries adjusted to higher prices and evolving supply dynamics.
Technology expenditures remained a vital factor supporting manufacturing and export sectors. Shipments of semiconductors surged notably in Korea and Japan, with China also showing gains in technology exports. Industrial production related to technology expanded across much of Asia. Similar investments bolstered activity in the United States and parts of Europe. Consumer confidence improved in several advanced economies after May, while unemployment rates stayed low in many regions, although rising fuel costs continued to diminish household purchasing power.
US Economy Dominates Growth Projections in Advanced Markets
Forecasts indicate that the United States economy will grow by 2.2% in 2026 and 2.1% in 2027. Investment in artificial intelligence sustains business momentum, although cautious consumer spending limits overall expansion. The eurozone is expected to see 1.0% growth in both years. Elevated energy prices and interest rates continue to exert downward pressure on regional demand. Japan’s economy is projected to increase by 0.8% in 2026, followed by a slight slowdown to 0.7% in 2027.
China is predicted to expand by 4.5% in 2026 and 4.2% in 2027. India’s growth is forecast at 7.1% for the fiscal year 2026-27 after a 7.8% rise in the previous year. The country’s economy is expected to grow by 6.5% during 2027-28. Indonesia is projected to see 5.2% growth in 2026 and 5.1% in 2027. Meanwhile, Mexico is forecasted to grow by 1.5% this year and 1.8% next year.
Energy Price Hikes Sustain Elevated Inflation Levels Among G20 Nations
Inflation remains a prominent concern within the OECD outlook. The G20 economies are projected to experience headline inflation of 4.1% in 2026, up from 3.4% in 2025. This rate is expected to decrease slightly to 3.6% in 2027. Advanced G20 nations are likely to see inflation at 3.2% this year and 2.6% next year. In the US, inflation is forecast to decline from 3.6% in 2026 to 2.6% in 2027, while the euro area is expected to record rates of 3.0% and 2.9%, respectively.
The OECD highlighted that increased energy costs have driven up household expenses and added inflationary pressures in many economies. Additionally, long-term government bond yields have risen as borrowing and debt servicing costs have climbed. OECD Secretary-General Mathias Cormann noted that global growth has been more resilient than initially expected, though still weaker compared to last year. The organization emphasized the importance of sustainable public finances and targeted temporary support measures. It also pointed out that boosting productivity, improving skills, diversifying energy supplies, and broader adoption of artificial intelligence are crucial areas for economic policy development.
