IMF cuts global growth forecast as Middle East war sends oil prices surging

The world economy is being tested again. The International Monetary Fund has trimmed its global growth forecast for 2026, warning that an oil-price shock triggered by war in the Middle East is rippling across economies worldwide and threatening to revive the inflation that policymakers had spent years trying to tame.

In its latest assessment, the Fund projects global growth of 3.1% in 2026 — 0.2 percentage points below its January estimate and slower than the 3.4% pace recorded in 2025. Global inflation, meanwhile, is now expected to average 4.4% this year, up from a January projection of 3.8%, as higher energy costs feed through into prices around the world.

The downgrade marks a sharp reversal from late 2025, when forecasters had anticipated falling commodity prices and a gentle easing of inflationary pressure. The outbreak of conflict at the end of February upended those expectations almost overnight, reminding markets how quickly geopolitical shocks can reshape the economic outlook.

The oil shock at the centre

At the heart of the revision is energy. Before the war, the World Bank had projected that global commodity prices would fall to a six-year low in 2026, with Brent crude expected to average around $60 a barrel — a five-year low — amid an anticipated oil glut. The conflict shattered that scenario, sending prices climbing and forcing institutions to redraw their models.

The IMF has sketched a series of scenarios that illustrate just how exposed the global economy is to further energy disruption. The picture darkens considerably if prices stay elevated, underscoring the fragility of a recovery that had appeared, only months earlier, to be settling into a stable groove.

• Baseline: global growth of 3.1% in 2026, down from 3.4% in 2025
• Inflation now seen averaging 4.4% in 2026, up from 3.8% in January
• Adverse scenario (~$100 oil): growth slows to 2.5%, inflation rises to 5.4%
• Severe scenario ($110 in 2026, $125 in 2027): growth near 2%, a 'close call' with recession
• Pre-war forecasts had pointed to falling commodity prices and a six-year low

A delicate moment for central banks

The renewed inflationary pressure poses an acute dilemma for central banks, many of which had begun easing interest rates on the assumption that price growth was returning to target. A fresh energy-driven surge in inflation could force policymakers to keep borrowing costs higher for longer, weighing on households and businesses already squeezed by years of elevated prices.

Emerging and developing economies are seen as particularly vulnerable. Higher oil prices raise import bills, strain public finances and can put downward pressure on currencies, while tighter global financial conditions make it costlier to service debt. The Fund has repeatedly cautioned that the burden of such shocks falls unevenly across the global economy.

“The global economy is being tested again, and the margin for error is narrow. A sustained oil-price shock would slow growth and reignite inflation at the same time.”

Trade tensions add to the strain

The energy shock is not the only headwind. Trade frictions and tariff uncertainty have continued to cloud the outlook, complicating investment decisions and supply chains across multiple regions. The combination of geopolitical conflict and protectionist pressures has left businesses navigating an unusually uncertain environment, with knock-on effects for global growth.

Economists warn that the interaction of these forces is what makes the current moment dangerous. An oil shock on its own is manageable; an oil shock layered on top of fragile trade relations and stretched public finances is far harder to absorb.

Background

The IMF publishes its flagship World Economic Outlook twice a year, with interim updates, and its forecasts are closely watched as a barometer of global sentiment. The world economy had been gradually recovering from the inflation surge that followed the pandemic and earlier energy disruptions, with growth stabilising and price pressures easing through 2025. The eruption of conflict in the Middle East at the end of February 2026 introduced a major new source of risk just as that recovery appeared to be consolidating.

What it means

Much now hinges on the path of oil prices. If the conflict de-escalates and energy markets calm, the baseline 3.1% growth scenario remains plausible. But a prolonged disruption that keeps crude elevated could tip the world towards a sharp slowdown, with the Fund's most severe scenario flagging a 'close call' with global recession. For governments and central banks alike, the coming months will be an exercise in managing risk amid an unusually unpredictable backdrop.
