The UK's Q3 2026 (August) CPI month-on-month rate reached 0.5%, accelerating significantly from the previous 0.3% and meeting market expectations. This inflation rebound was primarily driven by the surge in energy and fuel prices sparked by Middle East geopolitics, with transport and housing service costs acting as the two main forces pushing up the data. The market expects the Bank of England to remain vigilant against second-round inflation effects and maintain a tight monetary policy in the short term to observe changes in wages and core prices.
