The Bank of England will probably need to raise interest rates next month and again in early 2027 to combat rising inflation, its chief economist has said.Signalling a sharp rise in mortgage payments for an estimated 2.3 million homeowners who will have to refinance their loans next year, Huw Pill said that while the decision to nudge interest rates from 3.75% to 4% earlier this month was a “significant step” towards getting monetary policy into a better place, “we ⁠have further to go”.Pill told the Financial Times: “My view would be, we will see evidence that motivates further rises,” adding that the central bank would “do ‌what is necessary to get inflation back to 2% through time”.The chief economist is one of a number of the Bank’s policymakers who believe the UK economy has gained in strength over the last year, handing workers the power to bid up wages.Recent figures showed the economy grew by 0.7% in the third quarter, to give an annual rate of growth that was only surpassed by the US among the G7 group of wealthy countries.Huw Pill.

Pill said these expectations were “not outrageous”, hinting that he could vote for more substantial increases in the cost of borrowing at the next meetings of the Bank’s monetary policy committee (MPC) because the “ability to be ​modest [in the scale ​of rate rises] has diminished”.City analysts have interpreted the increasingly hawkish comments of Pill and other MPC members as making an interest rate rise in December almost inevitable. But there is disagreement about the strength of the economy, with many concerned that further increases in the cost of borrowing will hit the manufacturing sector and the construction industry, which has contracted for much of the year.Households are also likely to cut back on spending in the new year, when the energy price cap is expected to rise to almost £2,000 for a typical home and council tax bills increase by an average of almost 5%.
