PARIS, FRANCE / RankWire.AI / – The OECD has increased its forecast for global economic expansion in 2026 to 2.9%, citing a more robust world economy than previously anticipated. This adjustment marks a rise from the 2.8% predicted in the organization’s June report. Nonetheless, the OECD has reduced its 2027 growth estimate to 3.0% from 3.1%. Continued investments in artificial intelligence-driven sectors have kept production, trade, and overall economic activity buoyant. Meanwhile, rising energy prices and inflationary pressures persisted across key economies.
The September Interim Economic Outlook revealed that global growth slowed during the first half of 2026, with the annualized rate declining to 2.6%, compared to 3.6% in the latter half of 2025. Despite this slowdown, many energy-importing and exporting nations experienced stronger-than-expected economic activity. Contributing factors included substantial oil inventories, additional production outside the Gulf region, and alternative supply routes that mitigated the energy shock. Additionally, reduced oil demand from China contributed to balancing global energy markets.
The OECD emphasized that technology investment continues to be a vital driver of economic resilience. Semiconductor exports saw a sharp rise in Korea and Japan, while China also reported increased technology exports. Industrial output related to technology experienced rapid growth throughout much of Asia. Similar expansion was observed in the United States and several European nations. Consumer confidence improved in advanced economies after May, and unemployment rates remained low in many countries. However, elevated fuel costs continued to challenge household purchasing power.
US Economic Growth Gains Momentum While Eurozone Remains Flat
The US economy is forecast to expand by 2.2% in 2026 and 2.1% in 2027. This growth is supported by strong investment related to artificial intelligence, although slowing consumer spending and modest real income growth have limited overall gains. The euro area’s GDP is expected to increase by 1.0% in both years, with high energy prices and rising interest rates dampening activity across the region. Japan’s economy is projected to grow 0.8% in 2026 before easing slightly to 0.7% in 2027.
China’s economy is anticipated to grow 4.5% in 2026, then slow to 4.2% in 2027. India is expected to achieve 7.1% growth during the 2026-27 fiscal year, following 7.8% in the previous year. Growth projections for India’s 2027-28 fiscal year stand at 6.5%. Indonesia’s economy is forecasted to expand 5.2% in 2026 and 5.1% in 2027. Mexico’s economy is predicted to grow 1.5% this year and 1.8% in 2027.
Inflation in G20 Countries Rises Amid Energy Price Pressures
Inflation remains a significant challenge within the OECD outlook. The G20 economies are projected to experience a headline inflation rate of 4.1% in 2026, up from 3.4% in 2025, with a forecast decrease to 3.6% in 2027. Advanced economies within the G20 are expected to see inflation of 3.2% this year and 2.6% next year. The United States’ inflation rate is predicted to fall from 3.6% in 2026 to 2.6% in 2027, while euro area inflation is forecast at 3.0% and 2.9%, respectively.
The OECD highlighted that rising energy costs have driven up household expenses and renewed inflationary pressures in many countries. Additionally, long-term government bond yields have increased as public borrowing and debt servicing costs continue to rise. OECD Secretary-General Mathias Cormann noted that global growth has performed better than expected, though the economy remains weaker than last year. The organization recommends targeted, temporary support measures, sustainable public finances, and enhanced long-term productivity. It also encourages governments to focus on expanding skills, diversifying energy sources, and promoting wider adoption of artificial intelligence.
