The International Monetary Fund released three distinct scenarios for the path of global gross domestic product in 2026 and 2027 amid substantial uncertainty tied to the war in the Middle East. The scenarios differ by assumed conflict duration and the magnitude and persistence of energy market disruptions.
The IMF's central projection, described as the reference forecast, rests on the assumption that the conflict will be short-lived and that disruptions to energy supplies will fade relatively quickly. Two additional outlines capture progressively worse alternatives: an adverse scenario reflecting a longer and deeper conflict, and a severe scenario capturing much broader and more sustained disruption.
Key numerical parameters the fund published for each scenario follow in the table below. They show estimated global GDP growth, annual average oil prices per barrel and headline inflation for 2026 and 2027:
| IMF Scenario | 2026 | 2027 |
|---|---|---|
| REFERENCE FORECAST |
|
|
| ADVERSE SCENARIO |
|
|
| SEVERE SCENARIO |

The scenarios are intended to capture a range of plausible outcomes rather than predictions. The reference forecast reflects the IMF's baseline view under the assumption that energy market pressures will be transient. The adverse and severe scenarios illustrate how slower normalization or an intensification of hostilities could lift near-term oil prices and push headline inflation higher while trimming global growth.
For stakeholders tracking production rates, supply chains and working-capital dynamics, the three paths emphasize how differences in energy costs and inflation can translate into cash-flow effects. The scenarios also provide a framework for assessing risks to sectors sensitive to commodity prices and cyclical demand.
Summary
The IMF issued three scenarios for global GDP growth in 2026-27 tied to alternative assumptions on the duration and impact of the Middle East conflict. The reference forecast assumes a short-lived conflict and quickly fading energy disruptions; the adverse and severe scenarios assume longer, deeper disruptions, with higher oil prices and headline inflation and lower growth.
