Resilience under strain: an energy shock, an AI boom and what markets are pricing

Two shocks pulling in opposite directions

The IMF’s October 2026 World Economic Outlook carries a deliberately ambivalent title: resilience under strain. Global growth is projected to slow to 3.1 percent in 2026, from 3.5 percent in 2025, before recovering to 3.4 percent in 2027. Global headline inflation is projected to rise notably, to 4.7 percent this year, before easing to 4.1 percent next year. Slower growth combined with faster inflation is an uncomfortable mix, but the Fund does not describe a collapse. It describes an economy absorbing a shock while relying on buffers that are not unlimited. [1] [2]

The IMF’s chief economist, Silvana Tenreyro, framed the outlook as the net result of two forces. The first is the rise in energy and other commodity prices triggered by the war, which acts like a negative global supply shock: it raises prices and holds back activity at the same time. The second is the technology boom, mostly driven by artificial intelligence, which acts as a positive demand shock, lifting both prices and activity, particularly through investment and trade. [3]

This distinction matters for markets because the two forces do not land in the same places. A supply shock redistributes income from energy importers to energy exporters and squeezes households’ real incomes. A demand boom concentrated in technology favours the countries, sectors and firms that build the equipment. Global averages therefore conceal sharply different experiences, and a portfolio exposed to one force can look very different from one exposed to the other.

Where the divergence shows up in the numbers

The IMF’s statistical tables make the divergence concrete. Advanced economies as a group are projected to grow 2.1 percent in 2026. The United States is projected at 2.3 percent in both 2026 and 2027, the euro area at 1.1 percent and 1.2 percent, and Japan at 0.7 percent in both years. Emerging market and developing economies slow more markedly, from 4.5 percent in 2025 to 3.7 percent in 2026, before an expected rebound to 4.4 percent in 2027. [2]

The regional detail is more striking. The Middle East and Central Asia group is projected to contract by 0.3 percent in 2026, then grow 6.3 percent in 2027, a profile consistent with an economy disrupted by conflict this year and expected to recover if that disruption fades. Emerging and developing Asia remains the fastest-growing region at 5.1 percent, while Latin America and the Caribbean is projected at 2.3 percent and emerging and developing Europe at 1.7 percent. [2]

The Fund states plainly that energy-importing economies outside the technology value chain face the most difficult outlook. [1] That sentence is a useful map for investors. Countries that both import energy and lack a large role in AI hardware absorb the cost of the supply shock without receiving the offsetting benefit of the demand boom. Their currencies, bond spreads and equity valuations are the ones most directly exposed if commodity prices stay high.

Why inflation complicates the usual market reflexes

In a typical slowdown, investors expect central banks to cut rates and government bonds to rally. A supply-driven inflation shock weakens that reflex. With headline inflation projected at 4.7 percent globally, monetary authorities face pressure to avoid easing too soon, even as activity cools. [1] The IMF’s briefing explicitly calls for fiscal restraint to contain demand pressures at a time of high inflationary risks. [3]

For bond markets, this means growth disappointments do not automatically translate into lower yields. If inflation stays elevated, longer-dated yields can remain high because investors demand compensation for both inflation uncertainty and the volume of public borrowing. The IMF names higher borrowing costs and interest payments as a limit to resilience, warning that they could crowd out other spending and reduce buffers for future shocks. [3]

For equities, the implication is a narrower base of support. If earnings growth is concentrated among firms tied to AI investment while energy costs weigh on consumer-facing and energy-intensive sectors, headline indices can rise even while many companies struggle. Index performance then says more about a few large constituents than about the economy as a whole.

The AI boom as both support and vulnerability

The IMF credits the technology upturn with helping the global economy withstand geopolitics-driven disruptions. [1] Investment in data centres, chips and related equipment has supported trade and capital spending in a period when other drivers were weak. This is a real economic force, not merely a valuation story.

Yet the Fund also identifies the composition of growth as a limit to resilience. AI supply chains are highly concentrated in a few countries, sectors and firms, which creates potential chokepoints. [3] Among the downside risks, the outlook lists a reassessment of expectations surrounding artificial intelligence. [1] In plain terms, part of today’s growth depends on investors and companies continuing to believe that AI spending will pay off. If that belief weakens, investment could slow quickly and the markets most exposed to the theme could reprice.

The upside scenario is symmetrical. The IMF notes that stronger momentum in AI investment and productivity gains from AI could strengthen growth. [1] The honest conclusion is that the outcome is uncertain. The current evidence supports AI as a driver of investment; it does not yet establish how large the eventual productivity gains will be.

A risk balance tilted to the downside

The IMF judges risks to be skewed to the downside. Its list is specific: further escalation in conflicts, a reassessment of AI expectations, renewed trade tensions and fiscal vulnerabilities. [1] Tenreyro added extreme weather linked to El Niño, which could disrupt commodity markets further and exacerbate supply pressures. [3]

Several of these risks interact. A conflict escalation that lifts energy prices would raise inflation, which would keep rates higher, which would increase debt-service costs for governments already facing fiscal strain. An AI reassessment would hit precisely the investment that has been offsetting the energy shock. These are not independent coin tosses; they can reinforce one another, which is why the Fund emphasises building buffers now.

On the positive side, the outlook identifies a sustained easing of geopolitical and trade tensions as a possible source of stronger growth. [1] Markets that price only the downside scenarios could therefore be surprised if commodity pressures recede. The appropriate stance is to recognise both tails rather than treat either as certain.

Policy choices that shape market outcomes

Two analytical chapters accompany the forecast. Chapter 2 examines cost-of-living crises and concludes that governments should preserve price signals and rely primarily on temporary, targeted income support for the most vulnerable. [1] Broad energy subsidies or price caps may soften the immediate pain, but they weaken incentives to save energy and can be costly for public finances, a concern bond investors watch closely.

Chapter 3 studies corporate income tax policy and finds that its global effects depend on how changes are financed. Debt-financed tax cuts support domestic activity but can generate negative spillovers abroad in the short term. Over time, spillovers can become positive through cross-border knowledge transfer, but lower revenues can constrain domestic public investment, particularly in emerging market and developing economies. [1]

The common thread is fiscal credibility. The IMF urges fiscal frameworks to deliver better results when dealing with disruptive shocks and to build policy space through revenue measures. [1] For markets, governments that respond to the energy shock with targeted, temporary measures are likely to face less pressure on borrowing costs than those that commit to open-ended spending without financing.

What investors should watch

First, energy and commodity prices, since they drive the supply-shock half of the outlook and determine how much pressure falls on importers. Second, inflation data relative to the IMF’s projected path of 4.7 percent this year and 4.1 percent next year; a slower decline would keep central banks cautious. [1]

Third, signals about AI capital spending, including company investment plans and trade in technology equipment, because they underpin the demand-boom half of the story. Fourth, government bond yields and fiscal announcements, which show whether markets believe public finances can absorb higher interest costs. Fifth, the recovery assumption for the Middle East and Central Asia in 2027, which depends heavily on how the conflict evolves. [2]

None of these indicators provides a forecast on its own. Together they show which of the two forces is gaining the upper hand. The IMF’s message is that the world economy has adapted remarkably well, but that the margins which made adaptation possible are being used up. Investors who treat resilience as permanent risk being surprised; those who treat it as a buffer being drawn down are better prepared.

Limits of this analysis

IMF projections are conditional on assumptions about commodity prices, policies and the course of the conflict, and they are revised twice a year. Figures cited here come from the October 2026 publication and its statistical tables. This article explains how the projected forces could affect markets; it is not investment advice and does not predict the path of any specific asset price.
