The Bank of England yesterday warned the UK is facing its longest recession since records began, as it raised the interest rate by the most in 33 years.
It said the UK would face a "very challenging" two-year slump with unemployment nearly doubling by 2025.
Bank boss Andrew Bailey warned of a "tough road ahead" for UK households, but said it had to act forcefully now or things "will be worse later on".
It lifted the interest rate to 3% from 2.25% - the biggest jump since 1989.
By raising the rate, the Bank is trying to bring down soaring prices as the cost of living rises at its fastest rate in 40 years.
Food and energy prices have jumped in part because of the Ukraine war, which has left many households facing hardship and started to drag on the economy.
Definition of recession
The BBC explains a recession is defined as when a country's economy shrinks for two three-month periods - or quarters - in a row.
The Bank had previously expected the UK to fall into recession at the end of this year and said it would last for all next year.
But it now believes the economy already entered a "challenging" downturn this summer, which will continue next year and into the first half of 2024 - a possible general election year.
While it will not be the UK's deepest downturn, it will be the longest since records began in the 1920s, the Bank said.
The interest-rate announcement is the first since former Prime Minister Liz Truss and ex-Chancellor Kwasi Kwarteng unveiled their controversial mini-Budget in September.
Their plans for £45billion worth of unfunded tax cuts - much of which have been reversed - sent the value of the pound tumbling and sparked market turmoil, forcing the Bank of England to step in to restore calm.
Damage to UK's standing
Mr Bailey told the BBC he believed that the mini-Budget had "damaged" the UK's standing internationally.
He said that at a recent International Monetary Fund gathering in Washington "it was very apparent to me that the UK's position and the UK's standing had been damaged".
That same week, Mr Kwarteng was sacked as chancellor.
Chancellor Jeremy Hunt said: "The most important thing the British Government can do right now is to restore stability, sort out our public finances, and get debt falling so that interest-rate rises are kept as low as possible."
But shadow chancellor Rachel Reeves said families could not withstand such high rate rises "when we've got rising food prices, rising energy bills and now higher mortgage rates as well".
The latest rate hike - the Bank's eighth since December - takes borrowing costs to their highest since 2008, when the UK banking system faced collapse.
FTSE 100
The UK's top share index, the FTSE 100, was up 29 points at 7,217 shortly after opening this morning, following yesterday's 44-point gain.
Brent crude futures were up 1.91% at $96.48 a barrel.
