The world economy is decelerating faster than anyone in Davos predicted six months ago, and the causes are as old as macroeconomics itself: war, inflation, and the limits of central-bank magic.
International institutions and private forecasters have spent the past fortnight revising their 2026 growth estimates downward, some by as much as a full percentage point. The proximate trigger is the collapse of the Iran ceasefire and the resumption of hostilities that have sent oil prices lurching upward and shipping insurers scrambling. But the deeper story is structural: the post-pandemic sugar high has worn off, and policymakers are running out of ammunition.
The Iran factor
President Trump's declaration that the ceasefire is "over" and his threat of further strikes have injected fresh uncertainty into energy markets. Brent crude jumped sharply this week, and while prices remain below their 2022 peaks, the psychological effect on business confidence is disproportionate. Supply chains that had just finished recalibrating after the Strait of Hormuz disruptions are now bracing for another round of rerouting. European manufacturers, still nursing wounds from the energy shock of 2022-23, are particularly exposed; German industrial output was already contracting before the latest escalation.
Inflation's stubborn tail
Central banks had hoped to declare victory over inflation by mid-2026. Instead, core measures in the United States and the eurozone remain sticky, hovering above target. The Federal Reserve has paused its easing cycle, unwilling to cut rates while energy costs threaten a second-round price surge. The European Central Bank faces a grimmer calculus: growth is weaker, but inflation expectations are drifting upward. Neither institution has much room to stimulate demand without reigniting the price spiral they spent three years fighting.
Emerging-market fragility
The slowdown is not confined to the rich world. Emerging markets that depend on commodity imports—Turkey, India, much of Southeast Asia—are watching their current-account deficits widen as dollar-denominated oil bills climb. Meanwhile, commodity exporters like Brazil and Nigeria are discovering that higher prices do not automatically translate into fiscal windfalls when production is constrained and currencies are volatile. The IMF's latest regional updates read like a catalogue of downside risks.
Our take
Economic slowdowns rarely have a single villain, and this one is no exception. But the timing is brutal. Governments spent their fiscal reserves during the pandemic; central banks spent their credibility fighting inflation. Now, with geopolitical shocks multiplying and policy buffers depleted, the global economy is entering a rough patch with fewer shock absorbers than at any point since 2008. The optimists will point to resilient labour markets and household balance sheets. The realists will note that those strengths erode quickly once confidence cracks. Buckle up.
