Global growth is projected to hold steady at 2.6% in 2024 before edging up to an average of 2.7% in 2025-26. That is well below the 3.1% average in the decade before COVID-19. The forecast implies that over the course of 2024-26 countries that collectively account for more than 80% of the world’s population and global GDP would still be growing more slowly than they did in the decade before COVID-19.
Overall, developing economies are projected to grow 4% on average over 2024-25, slightly slower than in 2023. Growth in low-income economies is expected to accelerate to 5% in 2024 from 3.8% in 2023. However, the forecasts for 2024 growth reflect downgrades in three out of every four low-income economies since January. In advanced economies, growth is set to remain steady at 1.5% in 2024 before rising to 1.7% in 2025.
This year, one in four developing economies is expected to remain poorer than it was on the eve of the pandemic in 2019. This proportion is twice as high for countries in fragile- and conflict-affected situations. Moreover, the income gap between developing economies and advanced economies is set to widen in nearly half of developing economies over 2020-24 —the highest share since the 1990s. Per capita income in these economies—an important indicator of living standards—is expected to grow by 3.0% on average through 2026, well below the average of 3.8% in the decade before COVID-19.
Global inflation is expected to moderate to 3.5% in 2024 and 2.9% in 2025, but the pace of decline is slower than was projected just six months ago. Many central banks, as a result, are expected to remain cautious in lowering policy interest rates. Global interest rates are likely to remain high by the standards of recent decades—averaging about 4% over 2025-26, roughly double the 2000-19 average.
The latest Global Economic Prospects report also features two analytical chapters of topical importance. The first outlines how public investment can be used to accelerate private investment and promote economic growth. It finds that public investment growth in developing economies has halved since the global financial crisis, dropping to an annual average of 5% in the past decade. Yet public investment can be a powerful policy lever. For developing economies with ample fiscal space and efficient government spending practices, scaling up public investment by 1% of GDP can increase the level of output by up to 1.6% over the medium term.
The second analytical chapter explores why small states—those with a population of around 1.5 million or less—suffer chronic fiscal difficulties. Two-fifths of the 35 developing economies that are small states are at high risk of debt distress or already in it. That’s roughly twice the share for other developing economies. Comprehensive reforms are needed to address the fiscal challenges of small states. Revenues could be drawn from a more stable and secure tax base. Spending efficiency could be improved —especially in health, education, and infrastructure. Fiscal frameworks could be adopted to manage the higher frequency of natural disasters and other shocks. Targeted and coordinated global policies can also help put these countries on a more sustainable fiscal path.
