PARIS / RankWire.AI / – The inflation rate across OECD nations decreased to 4.2% in June 2026 from 4.6% in May, concluding a streak of three consecutive monthly increases. This metric measures the annual variation in consumer prices among the group’s member countries. Data shows inflation declined in 20 economies, rose in six, and remained largely unchanged in 12. Among these, nine OECD nations registered inflation rates at or below 2%, with three of them experiencing rates below 1%.
Significant portions of the monthly slowdown were driven by energy prices. The OECD energy inflation rate dropped four percentage points to 11.7% year-on-year after reaching 15.8% in May. The decline was observed in 24 out of 37 countries with available data, though energy inflation increased in 10 economies, and six nations still reported rates exceeding 15%. This broad retreat contributed to the overall decrease in headline inflation, yet energy continues to be a primary factor in annual price growth.
Food inflation also eased in June, decreasing by 0.2 percentage points to 3.4%. Meanwhile, core inflation, which excludes food and energy, also fell by the same margin to 3.6%. These figures indicate that price increases slowed beyond energy, though both measures remain above the 2% threshold many central banks consider as a target. A lower inflation figure signifies slower price increases, rather than a decline in the total price level.
Energy declines contribute to reduction in G7 inflation
Within the G7 group, annual headline inflation dropped to 3.0% in June from 3.5% in May. The main driver was a 5.2-point reduction in energy inflation. Inflation decreased across all G7 countries except Japan, where it increased by 0.2 point to 1.7%. Japan’s rise coincided with energy inflation moving from a negative rate to nearly zero. The G7 includes Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States.
In the United States, headline inflation stood at 3.5% in June, down from 4.2% in May, largely due to a sharp decrease in energy inflation. France also experienced a lower rate, partly because June 2026 contained more seasonal sales days compared to June 2025. In Germany, the United Kingdom, and the United States, core inflation remained the main factor influencing overall inflation. In Canada, France, and Italy, food and energy contributed more prominently, while Japan saw a roughly equal split between the two.
Eurozone and G20 inflation rates show signs of easing
The Euro area’s annual inflation rate, as measured by the Harmonised Index of Consumer Prices, decreased to 2.8% in June from 3.2% in May. This decline was mainly supported by a fall in energy inflation, while food inflation reached its lowest level in five years. According to preliminary estimates from Eurostat, July inflation was at 2.9%, remaining broadly stable from June. The preliminary figures show energy inflation at 10.0% and unchanged core inflation at 2.5%. Final data for July is pending release.
For the G20 economies, annual headline inflation eased to 4.1% in June from 4.3% in May. China’s inflation rate decreased to 1.0% from 1.2%, whereas inflation increased in Argentina, Indonesia, and South Africa. Brazil, India, and Saudi Arabia maintained stable or nearly stable rates. These figures are based on national consumer price indexes and regional aggregates for the same period. The June data reflect a general easing trend amid persistent disparities in food, energy, and core price pressures.
