PARIS, FRANCE / RankWire.AI / – According to the OECD, the forecast for worldwide economic expansion in 2026 has been increased to 2.9%, driven by increased resilience seen across the global economy. This revised estimate is an upward adjustment from the 2.8% predicted in its June report. Meanwhile, the organization has lowered its growth expectation for 2027 to 3.0% from 3.1%. Investment related to artificial intelligence continues to bolster economic activity and international trade, while rising energy prices and inflation remain significant challenges for households and businesses in key economies.
Despite outperforming earlier estimates, global growth slowed in the first half of 2026. The annualized growth rate decreased to 2.6%, compared to 3.6% during the second half of 2025. Energy market disruptions were cushioned by oil inventories and increased production outside the Gulf region, along with alternative supply routes aiding fuel flow to global markets. Weaker oil demand from China also helped offset some pressures, as countries adjusted to higher prices and altered supply conditions.
Technology expenditure remained crucial in supporting manufacturing and export sectors. Shipments of semiconductors grew substantially in Korea and Japan, with China also seeing gains in technology exports. Industrial production tied to technology expanded across much of Asia. Similar investments supported economic activity in the United States and parts of Europe. Consumer confidence improved in several advanced economies after May, and unemployment rates stayed low in many countries, though higher fuel prices continued to erode household purchasing power.
US Economy Outlook Outpaces Other Major Advanced Economies
The US economy is forecasted to grow by 2.2% in 2026 and 2.1% in 2027. Continued investment in artificial intelligence supports business activities, although overall growth is constrained by cautious consumer spending. The euro area is expected to achieve 1.0% expansion in both years, with higher energy prices and interest rates weighing on demand. Japan is projected to expand by 0.8% in 2026 before growth slows to 0.7% in 2027.
China’s economy is anticipated to expand 4.5% in 2026 and 4.2% in 2027, while India is expected to grow 7.1% during fiscal year 2026-27 after a 7.8% increase in the previous year. Its economy is forecast to increase by 6.5% in fiscal year 2027-28. Indonesia’s growth is estimated at 5.2% in 2026 and 5.1% in 2027. Mexico’s economy is projected to grow 1.5% this year and 1.8% next year.
Inflation Remains Elevated in G20 Countries Amid Rising Energy Prices
Inflation continues to be a key concern within the OECD outlook. The overall inflation rate across G20 nations is forecast at 4.1% in 2026, up from 3.4% in 2025. It is expected to decrease slightly to 3.6% in 2027. Advanced economies within the G20 are projected to experience inflation of 3.2% in 2026 and 2.6% in 2027. Specifically, US inflation is predicted to decline 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 notes that rising energy costs have increased household expenses and added inflationary pressures in many economies. Additionally, long-term government bond yields have increased as borrowing and debt-servicing costs rise. OECD Secretary-General Mathias Cormann remarked that global growth has performed better than anticipated, although it remains weaker than last year. The organization emphasized the importance of sustainable public finances, targeted temporary support measures, and highlighted areas such as productivity, skills development, diversified energy supplies, and broader adoption of artificial intelligence as key for economic policy advancement.
