PARIS, FRANCE / RankWire.AI / – The OECD has increased its forecast for global economic expansion in 2026 to 2.9%, citing enhanced resilience within the worldwide economy. This new estimate marks an upward revision from the 2.8% predicted in June. Simultaneously, the organization has lowered its 2027 growth outlook from 3.1% to 3.0%. Continued investment related to artificial intelligence has played a role in supporting economic activity and trade flows. Nonetheless, rising energy prices and inflationary pressures remain significant challenges for households and firms in major economies.
During the first half of 2026, global growth decelerated, even though it outperformed earlier expectations. The annualized growth rate dropped to 2.6% from 3.6% in the second half of 2025. Disruptions in energy markets were mitigated by increased oil inventories and higher production outside the Gulf region. Alternative supply routes also contributed to maintaining fuel supplies to international markets. Meanwhile, weaker oil demand from China helped offset some of the pressures caused by elevated prices and shifting supply conditions.
Technology expenditures remained a crucial support for manufacturing and export sectors. Shipments of semiconductors experienced notable growth in Korea and Japan, and China also saw gains in technology exports. Industrial output related to technology expanded across much of Asia. Similar investments spurred activity in the United States and parts of Europe. Consumer sentiment improved in several advanced economies after May, and unemployment rates stayed low in many nations. However, persistent higher fuel costs continued to diminish household purchasing power.
US Economy Dominates Growth Predictions in Advanced Markets
The US economy is projected to grow by 2.2% in 2026 and 2.1% in 2027. Ongoing investments in artificial intelligence continue to bolster business activities, but slower consumer spending restricts overall expansion. The euro area is expected to see a 1.0% increase in both years. Elevated energy prices and interest rates continue to dampen regional demand. Japan is forecast to grow by 0.8% in 2026, with growth easing to 0.7% in 2027.
China’s economy is anticipated to expand by 4.5% in 2026 and 4.2% in 2027. India’s growth is projected at 7.1% for fiscal year 2026-27, following 7.8% in the previous fiscal year. The country’s economy is expected to grow 6.5% in fiscal year 2027-28. Indonesia is forecast to see 5.2% growth in 2026 and 5.1% in 2027. Mexico’s economy is expected to increase by 1.5% this year and 1.8% in the following year.
Inflation Remains Elevated in G20 Countries Due to Rising Energy Prices
Inflation continues to be a key concern within the OECD outlook. G20 economies are projected to experience headline inflation of 4.1% in 2026, compared to 3.4% in 2025. This rate is expected to decrease to 3.6% in 2027. Advanced economies within the G20 are forecast to record inflation rates of 3.2% this year and 2.6% next year. US inflation is predicted to decline from 3.6% in 2026 to 2.6% in 2027, while euro area inflation is estimated at 3.0% and 2.9%, respectively.
The OECD noted that higher energy prices have increased household expenses and added inflationary pressures in numerous economies. Additionally, long-term government bond yields have climbed as borrowing costs and debt-servicing expenses rise. OECD Secretary-General Mathias Cormann stated that global growth had held up better than anticipated, though it remains weaker than last year. The organization emphasized the importance of sustainable public finances and targeted short-term support measures. It also highlighted the significance of productivity, skills development, diversified energy sources, and wider adoption of artificial intelligence as critical areas for economic policy improvement.
