OECD headline inflation declined to 4.0% in May 2025
Year-on-year inflation in the OECD as measured by the Consumer Price Index (CPI) declined to 4.0% in May 2025, from 4.2% in April. This marks the lowest level since June 2021 and represents a drop of 6.7 percentage points (p.p.) from the peak recorded in October 2022. While the pace of OECD headline inflation has moderated, average price levels continue to rise at almost twice the 2019 average rate and were 33.7% higher than in December 2019.
Year-on-year inflation in the G7 remained stable in May, holding at 2.4% for the third consecutive month. Inflation was stable or broadly stable in all countries except in Italy, where headline inflation slowed due to a 0.3 p.p. fall in core inflation and a decrease in energy prices. Across the G7 countries, core inflation remained the primary driver of headline inflation, except in Japan, where the combined contribution of food and energy inflation exceeded that of core inflation.

Artificial intelligence (AI) is a transformative technology capable of tasks that typically require human-like intelligence, such as understanding language, recognising patterns, and making decisions. AI holds the potential to address complex challenges from enhancing education and improving health care, to driving scientific innovation and climate action. But AI systems also pose risks to privacy, safety, security, and human autonomy. Effective governance is essential to ensure AI development and deployment are safe, secure and trustworthy, with policies and regulation that foster innovation and competition.Learn more

Despite progress in recent years, more work needs to be done across all OECD countries to secure gender equality, with women and girls still facing inappropriate disadvantages and barriers in most spheres of social and economic life. Gender equality must remain a priority, as a matter of basic human rights and long-term economic wellbeing and prosperity. It drives economic growth, strengthens democracy, enhances social cohesion and increases the well-being of all members of society.Learn more

Global value chains (GVCs) account for about 70% of international trade, as services, raw materials, parts, and components cross borders—often multiple times. As the trend toward cross-border supply chains increases, new challenges are emerging around sustainability, efficiency, and resilience. This growing complexity calls for policies that take a whole-of-chain approach to supply chain management and global trade.Learn more
