The United Kingdom has experienced the steepest reduction in economic growth projections among major wealthy nations, as the International Monetary Fund revised its outlook downward on Tuesday. This adjustment reflects the country’s significant vulnerability to inflationary pressures stemming from the ongoing conflict involving Iran.
Finance Minister Rachel Reeves, arriving in Washington for the IMF’s Spring Meetings, criticized the United States for lacking a clear exit strategy in the Iran conflict, calling it a “folly”. The IMF now anticipates the UK economy will expand by only 0.8% in 2026, a notable decline from the earlier forecast of 1.3%. This downgrade is the largest among the Group of Seven economies, placing the UK on par with Germany and slightly behind France, but ranking lowest in per capita growth within the G7.
The IMF attributed the dimmer outlook to the U.S.-Israeli war with Iran, which initially caused natural gas prices—critical to the UK—to double. Additionally, the Bank of England’s slower pace in reducing interest rates due to the energy price shock has contributed to the subdued forecast. The Fund warned that global growth predictions might be further lowered if the conflict persists.
Prior to the forecast release, Reeves expressed her frustration and anger over the U.S. failure to establish clear war objectives or an exit plan, emphasizing the negative impact on families in both the UK and worldwide. This economic setback threatens the commitments made by Prime Minister Keir Starmer and Reeves to accelerate growth and enhance living standards.
The IMF also projects the UK’s unemployment rate to increase to 5.6% in 2026, up from 4.9% in 2025. Meanwhile, the Conservative Party criticized Reeves’ policies, including increased employer taxes, as factors contributing to the growth downgrade and rising unemployment. A recent survey revealed that confidence among major British companies has plummeted to its lowest level since the COVID-19 pandemic began, while public inflation expectations have surged.
Looking ahead, the IMF expects the UK’s economic growth to rebound to 1.3% in 2027, though this remains 0.2 percentage points below previous estimates. Inflation, which has been the highest in the G7 for much of the past four years, is forecast to peak near 4% and average 3.2% throughout 2026, only returning to the Bank of England’s 2% target by the end of 2027. This contrasts with the IMF’s earlier forecast that inflation would fall to 2.5% in 2026.
The IMF’s outlook aligns with the Organisation for Economic Co-operation and Development’s recent downgrade of the UK’s 2026 growth prospects, which was the largest among major economies, alongside a faster anticipated rise in inflation.
Reeves is expected to announce measures this week aimed at assisting businesses burdened by high energy costs and has indicated that targeted support for low-income households is under consideration. IMF Chief Economist Pierre-Olivier Gourinchas highlighted the challenge Reeves faces in balancing economic support with fiscal responsibility, noting the market’s sensitivity to UK fiscal developments amid increased government borrowing costs since the conflict began.
