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

The International Monetary Fund (IMF) maintained its 2027 global growth forecast at 3.4%, citing the Middle East conflict and increasing public debt as threats to the economic outlook. The IMF slightly raised its 2026 growth forecast to 3.1% from 3.0% in July, attributing this to AI-related investment offsetting higher energy costs.

Despite this, the growth projection is still below the 3.5% growth seen in 2025. In its World Economic Outlook released at the IMF and World Bank annual meetings in Bangkok, the IMF warned that global economic resilience was increasingly under pressure. They noted that technology investment and efforts to redirect energy supplies had helped cushion the impact of the Middle East conflict, but these buffers were beginning to fade.

The US and China account for more than three-quarters of global net import demand for chips and other AI equipment. Currently, just 32 countries are projected to generate 95% of global growth, down from 54 in April. Forty percent of economies had their forecasts downgraded since April, indicating a growing number of economies facing challenges.

While oil reserves, alternative suppliers, and lower consumption have prevented a further decline in global growth to 2.5% in 2026, these protections are weakening. The IMF projects oil prices to average $96 a barrel in 2026, rising nearly 41% from the previous year, but falling to $87 in 2027. This baseline assumes normal shipping resumes in the Strait of Hormuz by March 2027 and conditions broadly return to normal by October.

However, if oil prices reach $130 a barrel in the first quarter of 2027, global growth could decline by 0.2 percentage points in 2026 and 0.5 percentage points in 2027, while inflation could rise to 5.2% next year. High public debt, deficits, and borrowing costs are limiting governments' ability to cushion another energy shock. The IMF advised governments to rebuild fiscal buffers and stabilize debt, while suggesting central banks should differentiate between temporary price increases and entrenched inflation.

The IMF's outlook hinges on restored energy flows and continued AI investment. Should these setbacks occur, the result could be weaker growth and more persistent inflation.
