The energy supply shock following the onset of the Iran conflict is expected to significantly weigh on global growth while putting new upward pressure on inflation, according to the latest OECD Interim Economic Outlook.
The document projects global growth of 2.9 per cent in 2026 and 3 per cent in 2027.
Headline inflation in G20 nations is projected at 4 per cent in 2026, easing to 2.7 per cent in 2027.
