The global economy has avoided the sharp downturn many feared after the war in the Middle East drove energy prices higher. But the apparent resilience is becoming harder to sustain. Growth is being supported by an artificial-intelligence investment boom and still-strong trade in technology goods, while governments, households and central banks absorb the costs of energy volatility, high debt and renewed inflation.
The International Monetary Fund projects global growth of 3.1% in 2026 and 3.4% in 2027, with the later figure modestly upgraded from its previous forecast. Yet the Fund also expects headline inflation to rise to 4.7% this year before easing to 4.1% in 2027. Its assessment is therefore less a declaration of recovery than a warning that growth is holding up unevenly and remains vulnerable to fresh shocks. The IMF outlook
Why growth has held up
Three forces explain the economy’s resistance. First, companies continue to spend heavily on data centres, chips, software and electricity infrastructure linked to AI. That investment has created demand across parts of the technology supply chain and helped offset weakness in more interest-sensitive sectors.
Second, trade has been stronger than expected. S&P Global reported that world trade volumes grew by more than 7% year on year in the third quarter to date, the fastest pace since 2021. Its global composite purchasing managers’ index also improved for a sixth consecutive month in September. Those figures suggest that tariffs and supply-chain adjustments have slowed, rather than stopped, cross-border commerce. S&P Global’s October outlook
Third, policymakers have so far contained the first-round effects of the energy shock. Stockpiles, public support measures and diversified supply networks have reduced the immediate risk of shortages. In advanced economies, inflation outside energy has remained more contained than during the post-pandemic surge, helping preserve consumer demand.
The shock beneath the headline numbers
Energy remains the central vulnerability. The United Nations estimates that Brent crude has risen roughly 40% since February to about $100 a barrel, with diesel, jet fuel and heating oil increasing even more sharply. Higher fuel costs move quickly through transport, food production and manufacturing, placing pressure on household budgets and business margins. The UN economic update
The consequences will not be evenly distributed. Energy-importing economies face a direct deterioration in their trade balances, while poorer households devote a larger share of income to essentials. The World Bank projects global growth at only 2.5% in 2026 and warns that developing economies could experience their weakest per-capita income growth since the pandemic. Its more pessimistic forecast reflects the fact that a global average can conceal significant losses in living standards. The World Bank’s Global Economic Prospects
Public finances add another constraint. Governments have used subsidies and fiscal support to cushion consumers, but borrowing costs remain elevated. In the United States, federal net interest outlays reportedly exceeded $1 trillion in fiscal 2026, while the deficit widened to nearly $2 trillion. Rising debt-service costs make it more difficult for governments to respond to the next shock without either raising taxes, cutting spending or accepting higher inflation.

AI boom or new financial risk?
AI investment is a genuine source of productivity potential, but its role in the current cycle is double-edged. The boom supports capital spending and exports today; its longer-term value depends on whether companies can generate sufficient revenues and productivity gains to justify the investment.
A sharp reassessment of AI-related shares has already exposed that uncertainty. Investors are questioning the sustainability of debt-financed infrastructure expansion and the valuations of firms whose profits may arrive years in the future. If spending slows abruptly, the impact could spread from chipmakers and data-centre operators to equipment manufacturers, utilities and highly leveraged borrowers.
Optimists argue that AI could eventually lift productivity, lower costs and create new demand, giving central banks more room to tolerate growth. Skeptics counter that the benefits may be concentrated among a small number of firms and economies, while the financial risks are widely distributed. Neither outcome is settled: the next phase will depend on adoption, financing conditions and whether productivity gains appear outside the technology sector.
What comes next
The immediate test is whether energy inflation broadens into wages, services and expectations. If it does, central banks may face the uncomfortable choice of keeping rates high or raising them even as growth weakens. S&P Global expects further rate increases from the Federal Reserve, European Central Bank and Bank of Japan before year-end, a prospect that would tighten conditions for households, companies and heavily indebted governments.
The more hopeful scenario is a contained energy shock, continued technology investment and gradual disinflation. The darker one combines a prolonged Middle East conflict with renewed trade tensions, an AI investment reversal and sovereign-debt stress. The IMF warns that escalation could keep food and energy prices volatile, weaken fiscal balances and reduce growth.
For now, resilience is real—but conditional. The world economy is not collapsing; it is operating with less room for error. The next shock will reveal whether AI-led investment has created a durable new engine of growth or merely bought time while older vulnerabilities deepen.
