Bank of England Rate Hike Back on the Table as Oil Shock Fans UK Inflation

The Quick Take

• City economists say a Bank of England rate hike in 2026 is back under consideration as oil disruption through the Strait of Hormuz threatens UK inflation
• Oil prices have spiked to levels seen during the Iran war, dampening market sentiment and complicating the BOE's monetary policy path
• Energy price shocks feeding into UK CPI could delay or reverse the BOE's expected rate cut trajectory for H2 2026

The Bank of England had been widely expected to continue its easing cycle through 2026 following a series of rate cuts from the cycle peak. However, the Iran war-era oil price spike — with crude rising sharply on Strait of Hormuz disruption fears — has introduced a stagflationary scenario that the BOE's Monetary Policy Committee must now navigate. City economists quoted in the report suggest the door to a rate hike has been reopened, which would mark a dramatic reversal from the trajectory the market priced just weeks ago.

The implications for UK gilt markets are significant: higher-for-longer BOE rates would keep 2-year and 5-year gilt yields elevated, pressuring mortgage refinancing costs and corporate bond issuance. UK housebuilders, leveraged consumer sectors, and highly indebted companies would face a renewed cost-of-capital squeeze. The FTSE 100, which has significant energy exposure through its oil majors, could see divergent performance — energy stocks benefit from oil price rises while consumer and financial shares face pressure from rate uncertainty and weakened demand.

The primary forward signal is the next UK CPI print — if energy pass-through pushes headline inflation back above 4%, the BOE's calculus shifts decisively toward holding or hiking rather than cutting. The Strait of Hormuz situation is the macro variable: any de-escalation in the Iran conflict that restores oil shipment flow would rapidly reduce inflation risk and allow the BOE to resume its easing path. Watch the next BOE Monetary Policy Committee meeting minutes for explicit language acknowledging the upside inflation risk.
