OECD Interim Economic Outlook (September 2026): growth held up better than expected, but risks persistThe world economy did better than expected, but worries remain

On September 23, 2026 the OECD published its Interim Economic Outlook. It says the global economy has weathered the energy supply shock from the conflict in the Middle East better than expected, but continued inflationary pressures and uncertainty weigh on the near-term outlook, and projects global growth of 2.9% in 2026 and 3.0% in 2027. G20 inflation is projected at 4.1% in 2026 and 3.6% in 2027.

Change in the global outlook (OECD)
June 2026September 2026
World growth 20262.8%2.9%
World growth 20273.1%3.0%
G20 inflation 20264.0%4.1%
G20 inflation 20273.1%3.6%

Key points

  • Global growth is projected at 2.9% in 2026 and 3.0% in 2027; the United States at 2.2% and 2.1%, the euro area at 1% in both years, China at 4.5% and 4.2%
  • G20 inflation is projected at 4.1% in 2026 and 3.6% in 2027, higher than previously projected, reflecting the surge in global energy prices
  • The oil shock was cushioned by alternative supply routes, inventory drawdowns including the co-ordinated release of strategic reserves, extra production outside the Gulf and lower oil demand; strong AI investment also supports trade and growth
  • Downside risks include fiscal pressures from rising long-term sovereign bond yields, AI investment that increasingly relies on external financing and could amplify a market correction if expected returns do not materialise, and weather-related pressure on food prices
Who is affected: Owners and accounting staff who want to check outlooks for interest rates, prices and the economy as assumptions for investment and funding

What to do in practice

  • Review borrowing terms and repayment plans for a period of rising long-term interest rates
  • Note what changed since the June outlook, and follow later revisions

The OECD, an international organisation, says the world economy handled the energy shock from the conflict in the Middle East better than expected. But prices are rising more easily again, and the “cushions” that softened the shock are wearing thin, so it is too early to relax.

What the OECD said
  • Applies: World growth held up better than expected
  • Applies: The cushions that softened the shock are wearing thin
  • Does not apply: There is no longer any worry about the pace of price rises
  • Applies: Investment in AI is supporting growth

Points

  • World growth is expected to be 2.9% in 2026 and 3.0% in 2027
  • Prices are expected to rise 4.1% in 2026 and 3.6% in 2027, higher than previously thought
  • Investment in AI is supporting world trade and growth
For example: On a rainy day an umbrella and raincoat may keep you dry, but as they wear out you start to worry about the next rain.
