PARIS / RankWire.AI / – Global economic activity within the OECD region experienced a slight uptick in the second quarter of 2026, driven by growth in most member nations reporting data. The gross domestic product increased by 0.5% compared to the previous quarter, surpassing the 0.4% rise observed in the first quarter. According to the Organisation for Economic Co-operation and Development, 27 out of 30 countries with available data saw economic expansion, while three recorded no change quarter-over-quarter.
Ireland achieved the highest quarterly growth, with GDP climbing 3.9%, followed closely by Israel with a 3.6% increase, both significantly above the overall OECD average. Conversely, Austria, Belgium, and Chile reported stagnation in economic output during the second quarter. On an annual basis, the entire OECD area’s GDP rose 2.3%, up from 1.7% in the first quarter, indicating a faster pace of growth year-over-year.
In contrast, the Group of Seven major economies experienced a slight slowdown. The combined G7 GDP grew by 0.3% in the second quarter, down from 0.4% in the previous period. Germany and Italy each saw a 0.2% increase, while Japan’s economy expanded by 0.3%. The United Kingdom and United States both registered growth of 0.4%, with Canada seeing a more robust 0.8% rise, and France returning to growth with a 0.2% increase.
Mixed Outcomes for G7 Economies in Q2
Several key economies experienced slower growth as shifts occurred in domestic demand and trade components during the period. Japan’s private consumption remained unchanged, while inventories and investment declined. In the United Kingdom, weaker private consumption coupled with reduced government expenditure dampened quarterly growth. The United States also faced slower export activity, inventory reductions, and lower government consumption, contributing to the overall deceleration among G7 nations.
Canada stood out among G7 members, jumping from zero growth in the first quarter to a substantial 0.8% increase in the second. France showed signs of recovery after contracting 0.1% earlier in the year, with its economy growing 0.2% in the second quarter. These results contrast sharply with Ireland and Israel, which posted rapid gains, while Austria, Belgium, and Chile experienced no change from the previous three months.
OECD’s Yearly Growth Accelerates to 2.3%
On an annual basis, the broader group of member countries demonstrated a quicker pace of economic growth. The OECD’s GDP was 2.3% higher than in the second quarter of 2025, compared to a 1.7% increase during the first quarter. Within the G7, the United States registered the strongest year-on-year growth at 2.1%, whereas Japan’s annual increase was the lowest at 0.5%.
The OECD characterized its second-quarter estimates as provisional, based on data from countries with available GDP figures. Its August 24 release covered 30 member economies, providing both quarterly and yearly comparisons. The organization plans to release its next quarterly GDP update on November 19, 2026. Despite the softer combined performance of the G7, overall growth across the OECD region remains slightly stronger according to recent data.
