IMF World Economic Outlook: Risks behind the Stock Market

When markets want to turn the page

A war in the Middle East, rising energy prices, heavy public deficits: in theory, all of this should weigh on stock screens. However, investors have mostly focused on the idea of a temporary shock. Stocks rebounded after the de-escalation announcements, and in some places, Wall Street even regained its pre-conflict levels. The message is clear: markets are betting on a quick return to calm, not on a lasting crisis.

This is where the gap between two worldviews comes into play. On one side, a finance that looks at profits, interest rates, and capital flows. On the other, economists who scrutinize second-round effects: more expensive energy, more persistent inflation, more fragile credit. The first camp sees resilience above all. The second camp sees the points of rupture.

IMF sees beyond the rebound

The International Monetary Fund revised its outlook in its latest April 2026 World Economic Outlook report. Its central scenario now expects global growth of 3.1% in 2026 and 3.2% in 2027, on the condition that the conflict remains limited in time and scope. The institution adds that global inflation should slightly rise in 2026 before easing in 2027.

The issue is not only the war itself. The IMF highlights several existing vulnerabilities: high public debt, trade tensions, stretched financial valuations, and sometimes eroded institutional credibility. In other words, the geopolitical shock does not hit a healthy system. It adds to existing imbalances, making contagion more likely.

In his presentation, Chief Economist Pierre-Olivier Gourinchas even warned that with a sustained increase in energy prices, financial conditions could tighten further. The risk is not just a slowdown. It is also a more classic chain reaction: higher costs, squeezed margins, more expensive credit, then slowed investment.

Why the Stock Market can rise when the economy slows down

At first glance, the paradox is surprising. But it is quite simple. The stock market does not reward the state of the actual economy in the short term. It values what matters for future profits: the speed of exiting crisis, the ability of companies to absorb costs, and the idea that a shock will remain contained. If investors believe that oil prices will normalize quickly, they buy. If they think a worst-case scenario remains unlikely, they buy even more.

In this context, the big winners are not the same across sectors. Energy majors, some defense groups, and actors capable of setting their prices can benefit from the tension. Potential losers are more numerous: airlines, chemicals, distribution, small businesses highly dependent on raw materials, and modest households that are quicker to feel the impact of rising fuel and food prices. The geopolitical shock is never evenly distributed. It first hits those with the least margin.

Financial imbalances, the other fault line

The debate is not just about “Stock Market versus IMF”. It mainly pits two time frames against each other. Markets look at the coming quarter. The IMF looks at the mechanism of risk accumulation. In its diagnosis, the combination of high debt and risk appetite can act as an amplifier. When everything is fine, it fuels the rise. When the climate changes, it accelerates the correction.

This is where the most fragile products of the moment come into play: heavily indebted private equity, cryptocurrencies, leveraged strategies, complex financing. As long as money flows, they give the impression of a robust system. But at the first serious shock, their illiquidity can become a collective problem. The IMF does not say that a crisis is certain. It says the ground is more slippery than it seems.

For states, the calculation is brutal. An economy shaken by energy and inflation often requires a trade-off between supporting purchasing power, defense spending, and controlling public finances. The IMF also emphasizes that an increase in military budgets can support short-term activity, but it can also exacerbate inflationary pressures and displace social spending. The immediate gain could therefore result in later fiscal tensions and social discontent.

Who wins, who loses, and what to watch

On the winning side in the short term are markets betting on a quick de-escalation, investors exposed to large values capable of absorbing shocks, and energy producers if prices remain high. On the losing side are energy importers, fuel-intensive sectors, households exposed to price increases, and fiscally fragile countries. The same shock can enrich portfolios and impoverish households at the same time.

The real issue now is not whether indices can still break records. They can. The real question is whether markets are not anticipating a return to normalcy too quickly. If the conflict persists, if oil remains above central banks’ comfort levels for a prolonged period, or if financial chains react poorly, the scenario of softness could quickly crack.

In the coming days, three things to watch are the evolution of the conflict, energy prices, and the next central banks’ reaction. As long as these three variables have not regained a semblance of stability, screen optimism will remain fragile. And the IMF will continue to look beyond the rebound.
