Recent upward revisions to UK CPI forecasts stem primarily from sustained energy price increases tied to the Middle East conflict, which has elevated wholesale oil and gas costs since early 2026. The September 2026 outturn reached 3.5%, with the Bank of England’s November Monetary Policy Report projecting a 2026 Q4 average near 3.8% and a peak near 5% in 2027 Q2 before easing. The Office for Budget Responsibility’s October outlook placed the 2026 annual average at 3.1%, while noting a 3.4% reading for 2027 amid higher energy pass-through and limited second-round wage effects. These developments, alongside the MPC’s 25-basis-point rate hike to 4% on November 5, have anchored trader consensus on the 3.5–3.9% range as the modal outcome, reflecting real-money aggregation of near-term data and policy responses.
