UK inflation forecasts have surged to 2.6% by year-end, driven by escalating energy costs from the Iran conflict, complicating the Bank of England’s monetary policy. The Treasury’s revised data, released Wednesday, shows projections now exceed the OBR’s prior 1.9% estimate, with economist Andrew Wishart attributing the spike to prolonged geopolitical tensions. 2.6%, up from 2.4% just weeks ago, reflects fears that prolonged disruptions in the Strait of Hormuz could keep prices elevated through 2027.

The Bank of England faces mounting pressure to address inflation despite holding interest rates at 3.75%. Markets now price in a higher likelihood of rate hikes by year-end, reversing earlier expectations for cuts. Two-year fixed mortgages hit 5.3%, the highest since February 2025, as lenders factor in energy-driven cost pressures. Pimco’s Peder Beck-Friis warned that even stabilized energy prices could leave inflation near 3% by December.

Growth forecasts for 2026 have been slashed to 0.9%, below the OBR’s 1.1% projection and the BoE’s estimates. Unemployment is expected to climb to 5.3%, up from 5.2%, as businesses grapple with elevated operational costs. Ellie Henderson of Investec highlighted cascading risks: higher gas prices threaten fertilizer production, potentially spiking food costs and triggering consumer price feedback loops.

The war in Iran has become a focal point for economic policymakers, with energy prices acting as a key catalyst for inflation. While a swift resolution could ease near-term pressures, the ripple effects on global supply chains and domestic industries underscore the BoE’s delicate balancing act between curbing inflation and sustaining growth.
