The Bank of England raised its key interest rate on Thursday for the first time in more than three years, lifting the base rate from 3.75% to 4%, and warned that inflation will climb to nearly 5% as the war in Iran drives up food, fuel, and energy prices across the UK and worldwide.
One policymaker voted to raise the key rate to 4.25%, according to CNBC. The move adds immediate pressure on households already squeezed by the cost of living.
Around 510,000 outstanding homeowner mortgages in Britain are on tracker deals that follow the Bank's base rate. UK Finance estimates those borrowers will see monthly payments rise by an average of £30.72. Another 470,000 homeowner mortgages sit on standard variable rates; if lenders pass on the full quarter-point increase, the average borrower pays an extra £14.28 a month, according to the banking trade body.
The roughly 87% of outstanding homeowner mortgages on fixed rates will not feel the hike immediately — but that protection is temporary. UK Finance says around 700,000 fixed-rate mortgages expire in the second half of this year, with another 2.3 million deals ending in 2027. Those borrowers will remortgage into a market already repriced for higher rates.
"Tracker borrowers will see payments rise almost immediately, while those coming off fixed deals face a mortgage market already repriced for higher rates," said Andrew Montlake, chief executive of mortgage broker Coreco.
The BBC spoke with Peter Gill, 48, who runs a small tiling business in Halifax and is one of the roughly 1.3 million Britons on a variable-rate mortgage. He told the BBC his monthly repayments will rise by around £45 following the quarter-point increase. With a combined household income of £45,000 and two children, Gill said increases in the national minimum wage have forced him to pay his staff more, raw material costs have climbed because of the war, and his family's food, gas, and electricity bills have all gone up. He says he now works "about six and a half days a week" to shield his family from the worst of it.
"From my point of view, inflation goes up which costs you, then interest rates go up and you have even less money," Gill told the BBC.
UK Finance is urging anyone who thinks they may struggle with higher repayments to contact their lender.
The Bank sharply increased its inflation forecasts alongside the rate decision, and the move was read as an attempt to get a grip on price growth linked to the Iran conflict. That conflict has pushed crude oil higher again: WTI traded around $90.60 a barrel in European trading late in the week, its second straight daily advance, according to market coverage. The ECB's chief economist, Philip Lane, warned that energy inflation would shape wage negotiations and price-setting. Eurozone producer prices rose 11.1% year-over-year in September.
The rate rise is not isolated. The Bank of Japan's minutes suggested members see room to accelerate rate increases if inflation overshoots expectations. Bank of Canada Governor Tiff Macklem told the House of Commons that further increases in interest rates could be necessary. Mexico's central bank unexpectedly cut its policy rate by 25 basis points to 6.25%.
In the US, New York Fed President John Williams said that with inflation having stayed excessively high for an extended period, this was an appropriate point at which to gather additional information.
Markets were uneven. Dow Jones futures sat near 51,170 after losing 0.85% in early European trading, while S&P 500 futures gained 0.06% to around 7,390 and Nasdaq 100 futures rose 0.90% to around 26,990. Bitcoin moved below $76,000 as crypto liquidations over 24 hours reached $1.08 billion. The yen gained ground on Thursday.
President Donald Trump said US approval was required before Iran could engage in activities connected with its nuclear program, according to the Times of Israel. It is not yet known how far the conflict will push energy prices, or how many more hikes the Bank of England will deliver over the next 18 months.
Our Take
Here's what the Bank of England just told every British household: the war in Iran is going to cost you, again, and the people who told you inflation was "transitory" are now raising your mortgage to fix it.
Notice who gets hit first. Not the bureaucrats in Threadneedle Street. Not the central bankers who spent years insisting the money printer was harmless. It's Peter Gill in Halifax, working six and a half days a week in a trade he's run for years, watching a £45 monthly increase land on top of higher staff costs, higher materials, and higher energy bills — all because a conflict an ocean away makes everything more expensive.
This is the same story Americans know from the Biden years: a central bank caught flat-footed, inflation allowed to run hot, and working families left holding the bill. The Bank of England's own forecast — inflation near 5% — is an admission that price stability was not defended when it mattered. Now the fix arrives as a rate hike, the bluntest instrument in the drawer, and the small business owner and the tracker borrower pay the price.
The contrast with the United States is the story here. Trump's second term has gone in the opposite direction: energy dominance, deregulation, tariffs used as leverage rather than apology. When Washington drills, prices come down. When London and Brussels lecture about net zero while war disrupts supply, families get £200-a-month mortgage shocks and a central bank scrambling to catch up.
Watch the 2.3 million fixed-rate deals expiring in 2027. That's the cliff. If the war drags on and the Bank keeps hiking, the squeeze moves from tracker borrowers to the whole market — and no politician who voted for the green agenda that left Britain dependent on volatile energy imports will be able to explain it away.
Americans should be paying attention. The lesson is simple: energy security is national security, and central banks cannot print their way out of a war. The countries that drill, build, and cut red tape will weather this. The ones that don't will keep sending the bill to the people who work six and a half days a week.
