The International Monetary Fund (IMF) has downgraded its global economic growth forecast due to the ongoing Iran war, warning that the conflict could push the world economy to the brink of recession if oil prices remain elevated. In its latest World Economic Outlook, the IMF presented three scenarios based on the war's duration and severity, with the most optimistic projection forecasting 3.1% global GDP growth in 2026, down from January's estimate of 3.3%. This scenario assumes a short-lived conflict and an average oil price of $82 per barrel in 2026, a decline from current levels near $100 per barrel. Without the Middle East conflict, the IMF stated it would have upgraded its growth outlook to 3.4% due to factors like lower interest rates and reduced US tariffs.
IMF Chief Economist Pierre-Olivier Gourinchas emphasized that the war poses a greater risk to the global economy than previous trade disruptions, such as President Donald Trump's tariffs. Under an "adverse scenario" of prolonged conflict, oil prices could average $100 per barrel in 2026 and $75 in 2027, leading to a 2.5% global GDP growth this year. The IMF's worst-case "severe scenario" warns of growth slowing to 2% in 2026 and 2027, with inflation exceeding 6%. The conflict has already driven up global inflation to 4.4%, up from the previous forecast of 3.8%. The IMF also highlighted financial stability risks, noting that the war has caused 8% declines in global equity prices and rising bond yields due to higher energy costs and inflation expectations.
Regional Impacts
The UK is expected to suffer the steepest economic downturn among G7 nations, with growth forecast to slow to 0.8% in 2026, a 0.5 percentage point downgrade from January. The IMF warned that UK inflation could reach 4%, double the Bank of England's target, while unemployment may rise to 5.6%, the highest since 2015. Chancellor Rachel Reeves acknowledged the war's economic impact but maintained that the UK is in a "stronger position."
In contrast, India's growth forecast was raised to 6.5% for 2026 and 2027, driven by strong domestic momentum and reduced US tariffs, despite the Middle East conflict. China's growth projection was lowered to 4.4%, missing the IMF's January estimate due to domestic slowdowns and war-related disruptions. The IMF also noted that a prolonged closure of the Strait of Hormuz could deepen economic instability, with inflation potentially rising to 5.4% in an adverse scenario.
Financial Market Risks
The IMF warned that the war has increased financial stability risks, including tighter funding markets and potential strain on non-bank lenders, hedge funds, and AI-driven borrowers. Rising debt-to-GDP levels and short-term securities issuance have heightened vulnerability to inflation-driven market volatility. The IMF cautioned that prolonged conflict could lead to abrupt financial tightening, triggering forced selling and outsized losses in leveraged markets.
The IMF urged global cooperation and adaptable policies to navigate the crisis, emphasizing the need for credible frameworks to mitigate long-term economic damage.
