IMF holds 2027 global growth forecast at 3.4% as war, debt risks mount

The International Monetary Fund has maintained its 2027 global growth forecast at 3.4%, citing mounting risks from the Middle East conflict and rising public debt. The IMF had previously upped its 2026 growth forecast from 3.0% to 3.1% in July, attributing this to AI-related investments offsetting higher energy costs. However, despite outpacing the 3.5% growth seen in 2025, this projection still falls short of the impressive 3.5% growth recorded in the previous year.

During the IMF and World Bank annual meetings in Bangkok, the fund highlighted that global economic resilience is increasingly being tested. While technology investment and efforts to redirect energy supplies have helped cushion the impact of the Middle East conflict, these buffers are gradually diminishing. In fact, just 32 countries are projected to generate 95% of global growth, a significant drop from the 54 countries previously identified in April. Moreover, 47% of economies have seen their growth forecasts downgraded since April.

Oil reserves, alternative suppliers, and lower consumption have managed to prevent global growth from plummeting to 2.5% in 2026; however, these protections are waning. The IMF anticipates oil to average $96 a barrel in 2026, a 41% increase, before dipping to $87 per barrel in 2027. This projection assumes the Strait of Hormuz shipping resumes in March 2027 and conditions generally normalize by October.

If oil prices reach $130 per barrel by the first quarter of 2027, global growth would take a 0.2 percentage point hit in 2026 and a 0.5-point dip in 2027, with headline inflation surging to 5.2% in 2027 from 4.1% in 2025.

High public debt, deficits, and borrowing costs have constrained governments' capacity to mitigate another energy shock. The IMF has urged governments to rebuild fiscal buffers and stabilize debt levels, while also advising central banks to differentiate between temporary price increases and entrenched inflation. Ultimately, the outlook hinges on the restoration of energy flows and continued AI investment. A setback in either area could result in weaker growth and more persistent inflation.
