PARIS, FRANCE / RankWire.AI / – The OECD has upgraded its projection for worldwide growth in 2026 to 2.9%, citing stronger resilience in the global economy. This marks an increase from its June forecast of 2.8%. Conversely, the organization has lowered its 2027 growth estimate to 3.0% from 3.1%. Continued investment in artificial intelligence has supported economic activity and trade, although persistent high energy prices and inflation remain significant pressures for households and businesses across leading economies.
During the first half of 2026, global expansion decelerated but outperformed earlier predictions. The annualized growth rate dipped to 2.6% from 3.6% in the second half of 2025. Energy market stability was aided by oil inventories and increased production outside the Gulf region, alongside alternative supply routes ensuring fuel flow to global markets. Reduced oil demand from China also helped offset some pressures as nations adjusted to elevated prices and shifting supply dynamics.
Technology expenditure continued to be a vital driver for manufacturing and exports. Semiconductor shipments surged notably in Korea and Japan, with China also posting gains in technology exports. Across much of Asia, technology-related industrial output expanded, while similar investments bolstered activity in the United States and parts of Europe. Consumer confidence improved in several advanced economies after May, and unemployment stayed low in many nations, although rising fuel costs continued to squeeze household budgets.
US Economy Sets the Pace for Growth Forecasts in Major Advanced Markets
The US economy is projected to grow by 2.2% in 2026 and 2.1% in 2027. Investment in artificial intelligence remains a key factor supporting business activity, even as subdued consumer spending limits overall expansion. The eurozone is expected to achieve 1.0% growth in both years. Rising energy costs and interest rates continue to dampen regional demand. Japan’s growth forecast is 0.8% for 2026, slowing to 0.7% in 2027.
China is forecast to grow 4.5% in 2026 and 4.2% in 2027. India’s expansion is projected at 7.1% in fiscal year 2026-27 after last year’s 7.8%, with growth slowing to 6.5% in 2027-28. Indonesia is expected to see 5.2% growth in 2026 and 5.1% in 2027. Mexico’s economy is forecast to increase by 1.5% this year and 1.8% next year.
Inflation Remains Elevated in G20 Countries Amid Rising Energy Costs
Inflation continues to be a key concern in the OECD outlook. G20 economies are expected to see headline inflation of 4.1% in 2026, up from 3.4% in 2025, and a decline to 3.6% in 2027. Advanced G20 nations are forecast to experience inflation rates of 3.2% this year and 2.6% next year, with the US expected to see a drop from 3.6% in 2026 to 2.6% in 2027. The euro area’s inflation is projected at 3.0% and 2.9%, respectively.
The OECD attributes higher energy prices to increased household expenses and inflationary pressures in many regions. Rising long-term government bond yields reflect growing borrowing and debt-service costs. OECD Secretary-General Mathias Cormann noted that global growth has held up better than initially expected but remains weaker than last year. The organization emphasizes the importance of sustainable public finances, targeted temporary support, and highlights productivity, skills, diversified energy sources, and broader adoption of artificial intelligence as critical policy areas.
