Bank of England Raises Key Interest Rate to 4 Percent Amid Energy Price Surge

The Bank of England raised its main interest rate from 3.75 percent to 4 percent on Thursday, marking its first rate hike since August 2023. The central bank acted after inflation reached an 11-month high of 3.5 percent in September, driven primarily by surging global energy prices resulting from the conflict in Iran and shipping bottlenecks in the Strait of Hormuz.

Members of the Monetary Policy Committee voted eight to one in favour of the quarter-point increase, with a single policymaker calling for a larger half-point adjustment. Updated quarterly forecasts released by the central bank indicate that inflation could rise to approximately 5 percent by mid-2027 as higher energy costs filter into household and commercial bills. Bank of England Governor Andrew Bailey stated that today’s increase shouldn’t be seen as the first in an inevitable long sequence of hikes, but added that unless the conflict in the Middle East is resolved, neither does it seem likely to be the last increase.

Alongside its inflation warnings, the central bank upgraded its economic growth projections for the United Kingdom. Gross domestic product is now expected to expand by 1.6 percent this year and 1.3 percent in 2027, up from the 1.1 percent growth previously forecast for both years in July. Officials also estimated that fiscal policy announced in the Budget would lower inflation by 0.25 percentage points by the second quarter of 2027, despite exerting a drag on growth over the medium term.

Prior to the outbreak of hostilities on 28 February, UK key rates had been falling from a 15-year peak of 5.25 percent. Market borrowing costs have since climbed, with benchmark two-year mortgage rates increasing by nearly half a percentage point since early September. Analysts at Investec noted that prolonged elevation of energy prices increases the risk that temporary cost spikes transform into broader wage and price pressures.

The central bank's decision follows parallel policy tightening by the US Federal Reserve and the European Central Bank, both of which recently raised rates due to energy-driven inflation. According to the Bank of England's latest Market Participants Survey, financial market participants expect the key interest rate to reach 4.25 percent at the committee's meeting in February 2027.
