OECD raises global growth outlook to 2.9% as world economy weathers Iran war energy shock

The global economy has proven more resilient than many analysts feared, with the Organisation for Economic Co-operation and Development revising its 2026 growth forecast upward to 2.9%, citing a better-than-expected absorption of the energy disruption triggered by the ongoing conflict involving Iran. The modest upgrade offers a degree of reassurance to policymakers, even as the organisation highlighted a cluster of risks that could yet derail the recovery.

The OECD’s updated assessment reflects growing confidence that energy markets have adjusted more smoothly to the geopolitical shock than initial projections suggested. Supply chain adaptations, shifts in energy sourcing and a degree of demand softening have collectively cushioned the blow, according to the report. The revision, while incremental, marks a meaningful departure from the more pessimistic scenarios that had circulated in financial markets earlier in the year.

Persistent risks cast shadow over improved outlook

Despite the upgraded headline figure, the Paris-based organisation was careful not to project undue optimism. Officials warned that inflation has remained stickier than desired across a number of major economies, complicating the task of central banks attempting to calibrate interest rate policy. Rising bond yields, which increase borrowing costs for governments and businesses alike, were also flagged as a structural concern that could weigh on investment and consumer spending in the months ahead.

The spectre of a prolonged or escalating conflict in the Middle East remained central to the organisation’s risk assessment. A longer war, officials indicated, could reignite upward pressure on energy prices, potentially unwinding some of the stabilisation that underpins the improved forecast. The 2.9% growth projection, while an improvement, still represents a relatively subdued pace of expansion by historical standards, and the margin between the baseline scenario and more adverse outcomes remains uncomfortably narrow, according to reports.

European economies, many of which are heavily exposed to energy import costs and trade flows through the broader Middle East corridor, are watching the situation with particular attention. The war has already reshaped energy procurement strategies across the continent, accelerating some existing trends toward diversification while also imposing short-term costs on industry and households. The OECD’s findings are likely to inform upcoming discussions among European finance ministers as they finalise budget frameworks for the coming year.

Bond markets reacted cautiously to the revised figures, with analysts noting that the combination of a marginally better growth outlook alongside persistent inflation does little to simplify the decisions facing the European Central Bank and other major monetary authorities. The question of when and how quickly to ease policy remains fiercely contested, and the OECD’s report is unlikely to resolve that debate conclusively.

Looking ahead, the organisation stressed that the durability of the current resilience depends heavily on factors outside the control of any single government or institution. Energy market stability, the trajectory of the Iran conflict and the pace at which inflationary pressures ease will all play determining roles. Policymakers were urged to maintain fiscal prudence while preserving space to respond should conditions deteriorate. For now, the slightly brighter growth number offers a measure of relief — though, as the OECD made clear, it is relief that remains firmly conditional.
