OECD Economic Outlook (June 2026): energy shock slows growth, two scenariosThe future is hard to read, so the OECD showed two possible futures
On June 3, 2026 the OECD published its Economic Outlook. It says the conflict in the Middle East has become the dominant force shaping global prospects through an energy shock and inflationary pressure. Global growth slows from 3.4% in 2025 to 2.8% in 2026 and picks up to 3.1% in 2027 if the disruption is time-limited, and falls to 2.1% in 2026 and 1.8% in 2027 if it is prolonged.
Key points
- Time-limited disruption scenario: global growth of 2.8% in 2026 and 3.1% in 2027; the United States 2.0% and 1.8%, the euro area 0.8% and 1.2%, China 4.5% and 4.3%
- Prolonged disruption scenario, with disruptions persisting well into 2027: global growth of 2.1% in 2026 and 1.8% in 2027; the OECD area 0.9% and 0.5% (against 1.5% and 1.7% in the time-limited case)
- G20 consumer price inflation rises from 3.4% in 2025 to 4.0% in 2026 and eases to 3.1% in 2027 in the time-limited scenario; it would rise significantly higher in the prolonged scenario
- On policy, fiscal support should be targeted and temporary; central banks need not respond to a supply-driven rise in prices while inflation expectations stay anchored, but a response may become necessary if broader price pressures intensify
What to do in practice
- Estimate your cash flow once for the case where disruption is prolonged, with higher purchase prices and interest rates
- Check later publications to see which scenario events are closer to
The conflict in the Middle East is casting a shadow over the world economy. The OECD, an international organisation, gave two outlooks: one in which the disruption ends fairly soon and one in which it drags on. If it ends soon, world growth in 2026 is 2.8%; if it drags on, 2.1%, a big difference.
Points
- The conflict in the Middle East has pushed energy prices up and made prices of goods rise more easily
- If the disruption ends soon, world growth is expected to be 2.8% in 2026 and 3.1% in 2027
- If it drags on, growth is expected to be much weaker: 2.1% in 2026 and 1.8% in 2027
What the words mean
- scenario
- a storyline of the future, thought through as “what if this happens”
- prices
- the general level of the prices of goods and services in shops
The evolving conflict in the Middle East has become the dominant force shaping global economic prospects, prompting an energy shock that is driving inflationary pressures and is projected to have adverse impacts on growth, according to the OECD’s latest Economic Outlook. Under the assumption of a lasting resolution of the conflict – the “time-limited disruption” scenario –the OECD projects global growth slowing from 3.4% in 2025 to 2.8% in 2026 before picking up to 3.1% in 2027.
