The IMF projects global growth of 3.1% in 2026 and 3.4% in 2027, but warns that expansion increasingly rests on a small number of firms, sectors and economies. The fund kept its 2026 forecast unchanged from April and lifted its 2027 estimate by 0.2 percentage points. It also raised its inflation forecasts as higher energy and food prices take a toll.
Growth and Concentrated Investment
The IMF expects the U.S. economy to grow 2.3% in both 2026 and 2027, the fastest pace among G7 economies. Its 2027 U.S. estimate rose 0.2 percentage points. The fund said the AI investment boom has helped counter the economic toll of the Middle East war and prolonged energy disruptions.
That support carries a concentrated risk. “Technology-related investment, while an important boon against the energy shock, is concentrating risks — making the global expansion heavily reliant on a small number of firms, sectors, and economies,” IMF economic counselor Silvana Tenreyro wrote in a blog post.
The IMF modeled what could happen if promised productivity gains fail to materialize and AI investment reverses. Under that scenario, an investment pullback and financial market correction could leave global GDP 1.1% below the fund’s baseline forecast by 2028. The projected U.S. GDP hit would be larger, at 1.8%.
The fund also sees another possible outcome. If AI investment strengthens and productivity gains arrive faster, global GDP could reach 0.6% above its baseline forecast by 2029. Continued AI investment could also fuel inflation and potentially prompt further interest rate hikes.
Energy Costs and Policy Buffers
The IMF forecasts global inflation of 4.7% in 2026, easing to 4.1% in 2027. Both projections rose from April as higher energy and food prices take a toll. The fund kept its growth outlook despite prolonged energy disruptions from the Middle East war.
Economies have weathered the energy shock partly by drawing down oil reserves and redirecting supplies. Global oil stocks are falling by roughly 2.7 million barrels a day, the IMF says. That raises the risk of a sharp price spike.
“Without shoring up supply capacity and replenishing policy buffers, the global economy could soon test the limits of resilience,” Tenreyro wrote. The statement identifies supply capacity and policy buffers as areas the fund says need strengthening; the forecasts don't specify a particular policy package.
Warnings Ahead of Finance Meetings
Global finance officials and central bankers are gathering in Bangkok this week for the IMF and World Bank’s annual meetings. The fund’s outlook sets out both the support AI investment has provided and the downside if investment reverses or energy pressures intensify.
The IMF said it has underestimated global growth in recent years, raising questions about whether economies have become better at weathering shocks. But resilience isn't a guarantee against the next crisis. Its projections place the immediate global growth outlook alongside risks tied to concentrated technology investment, rising inflation forecasts and declining oil stocks.
