The OECD said headline consumer-price inflation across its member economies reached 4.6% in May 2026, up from 4.3% in April, as higher energy prices fed into the annual comparison. [1] The number is a snapshot, not a universal household experience: energy exposure, subsidies and exchange rates differ sharply across countries.

Shock transmission is the story

The OECD’s June outlook links the renewed pressure to the Middle East conflict and an energy shock. In its time-limited disruption scenario, G20 inflation is projected to rise to 4.0% in 2026 from 3.4% in 2025 before easing in 2027. [2] That path describes a potential unwinding, not a guarantee.

For businesses, the transmission chain is familiar but uneven. Fuel and electricity raise transport and production costs; firms then decide how much to absorb, pass through or postpone. Households feel the result through food, travel, heating and services at different speeds.

Resilience does not mean no pain

The heads of the IMF, World Bank, WTO and IEA said on 8 July that the global economy had been broadly resilient to the Middle East war shock, while stressing that effects were uneven across energy, food, commodities and activity. [3][4] Resilience at the global level can coexist with a difficult quarter for energy-intensive firms or low-income consumers.

What to watch

The key indicators are not only the headline rate. Watch core inflation, wage settlements, freight and energy contracts, and whether expectations stay anchored. The OECD data make a simple point: once an energy shock enters prices, the policy problem becomes a balance between preventing second-round inflation and avoiding a deeper growth slowdown.
