The Bank of England cut interest rates on Thursday for only the second time since 2020 and said future reductions were likely to be gradual, as it saw higher inflation and economic growth after the new government's first budget.

The Monetary Policy Committee voted 8-1 to cut interest rates to 4.75 percent from 5 percent, a stronger majority than expectations in a Reuters poll for a 7-2 vote in favour of a cut. Catherine Mann dissented, preferring to keep rates on hold.

Sterling rose by almost half a cent against the US dollar immediately after the announcement. British government bond prices fell but quickly reversed that drop.

"We need to make sure inflation stays close to target, so we can't cut interest rates too quickly or by too much," BoE Governor Andrew Bailey said in a statement.

"But if the economy evolves as we expect it's likely that interest rates will continue to fall gradually from here," he added, broadly echoing his language after September's meeting.

The BoE predicted that finance minister Rachel Reeves' budget announced last week - which entails big increases in tax, spending and borrowing - would boost the size of Britain's economy by around 0.75 percent next year but barely improve annual growth rates in two or three years' time.

Her plan was likely to add just under half a percentage point to the rate of inflation at its peak in just over two years' time, the BoE said, causing inflation to take a year longer to return sustainably to its 2 percent target.

Reeves said families would welcome the BoE's rate cut.

The BoE's cautious language on the future interest rate cuts was similar to previous months, in keeping with investors' view that it is likely to cut interest rates more slowly than the European Central Bank.

The BoE did not refer to Donald Trump's US election victory, which has prompted a big reduction in bets that the Federal Reserve will cut interest rates aggressively.

The Fed is expected to reduce its benchmark policy rate by quarter of a percentage point later on Thursday.

After the BoE's rate cut, financial markets priced only around two interest rate cuts from the BoE in 2025 - compared with between two and three beforehand and down from around four before the budget.

The BoE said inflation was likely to rise to around 2.5 percent by the end of this year from 1.7 percent in September and hit 2.7 percent by the end of next year, before falling gradually below its 2 percent target by the end of the three-year forecast.

Government decisions to raise the cap on bus fares, hike value-added tax on private school fees and increase employers' social security contributions were likely to boost inflation.

With the latter measure combining with a 6.7 percent hike in the national minimum wage, the BoE said employers faced rising costs - although it could not be certain of the overall effect on inflation as employers might respond by sacking staff or accepting lower profits.

Two of Britain's biggest businesses, BT and Sainsbury's, said on Thursday that tax changes in the budget would fuel inflation.

While the BoE downgraded its forecast for average economic growth this year to 1 percent from 1.25 percent, reflecting recent revisions to past growth, it raised its forecast for 2025 to 1.5 percent from 1 percent.

"This reflects the stronger, and relatively front-loaded, paths for government consumption and investment more than offsetting the impact on growth of higher taxes," the BoE said.

While the BoE's forecasts for growth and inflation include the impact of higher spending and taxes, they do not include the effect of a big rise in market borrowing costs since the budget as it set those assumptions beforehand and did not update them.

If the now-higher market interest rates were factored in, the outlook for inflation and growth would likely be a bit lower.

The BoE repeated its message that monetary policy would need to stay "restrictive for sufficiently long" to return inflation sustainably to the 2 percent target. (Reuters)
