as had been expected. The regulator justified the move by stating that inflationary pressures had increased sufficiently to warrant an rise in the cost of borrowing.

In a statement, the Bank of England reported that a majority of the members of its Monetary Policy Committee—8 votes to 1—supported the rate hike, the first such increase in more than three years. According to the Bank, the single dissenting member had called for a larger, half-percentage-point increase to 4.25%.

This decision comes at a time when the war in Iran—now in its ninth month—has driven up energy prices and pushed inflation in the UK to 3.5% as of September. This figure marks an 11-month high and sits well above the Bank of England’s 2% target.

The Bank of England forecasts that consumer price growth in the UK will accelerate to approximately 5% by the middle of next year. However, the pace of price increases is subsequently expected to slow as the impact of fuel costs on the 12-month inflation rate wanes and the tightening of monetary policy serves to "constrain inflation," the Bank added.

Although officials noted "limited evidence" of the energy shock having secondary effects on broader prices and wages, the Bank of England stated that "the degree of inflationary pressure in the pipeline is sufficient to justify an increase in Bank Rate." Stronger-than-expected overall economic activity also bolstered the case for a rate hike, the Bank of England said.
