Bank of England Set to Raise Rates to 4% as Iran War Reignites Inflation

The Bank of England is expected to raise UK interest rates from 3.75% to 4% at its next meeting — the first increase in more than three years. Most analysts expect the move, according to the BBC's reporting, after the Bank held rates at its previous six meetings.

The expected hike caps a sharp reversal. At the start of 2026, markets expected two cuts this year, with the first arriving in March or April. The US-Israel conflict with Iran changed that calculus entirely, pushing up energy and fuel costs worldwide and reigniting inflation.

Why is the Bank turning hawkish again?

The Bank's base rate is what it charges other banks and building societies to borrow, and it filters through to mortgages, credit cards and savings. The Bank moves the rate to keep inflation at or near its 2% target — raising rates when prices climb too fast, cooling demand in the process.

UK inflation tells the story of why policy is tightening. CPI peaked at 11.1% in October 2022 after Russia's full-scale invasion of Ukraine, then fell significantly. But it's climbing again: 3.5% in the year to September 2026, up from 3.1% the previous month and well above target. The Office for National Statistics blamed the acceleration on sharp rises in petrol and diesel prices.

The rate history matters for context. The base rate hit 5.25% in August 2023 and stayed there until August 2024, when cutting began. Five cuts brought it to 4%, followed by holds in September and November 2025, a cut in December 2025, and holds in January, March, April, June, July and September 2026. Given the current uncertainty, many analysts expect a rise at the November meeting and again early next year.

What does this change for mortgage holders?

Just under a third of households have a mortgage, according to the government's English Housing Survey. The impact splits three ways:

• About 500,000 homeowners are on tracker mortgages that follow the Bank rate. A 0.25 percentage point rise adds roughly £31 a month to a typical loan, though the exact figure depends heavily on loan size.
• Another 500,000 sit on standard variable rates, waiting to see whether their lender passes on any rise. A 0.25 point increase typically means £14 more per month.
• Some 87% of mortgage customers hold fixed-rate deals, so their monthly payments don't move immediately — but their next deal will.

Lenders have largely priced a November hike into current offers. As of 3 November, according to financial information service Moneyfacts, the average two-year fixed residential mortgage rate stood at 5.97%, the average five-year fix at 5.99%, and the average two-year tracker at 4.67%.

The squeeze point: about 800,000 fixed-rate mortgages with rates of 3% or below are expected to expire every year on average until the end of 2027. Those borrowers face sharply higher refinancing costs.

What about savings, credit cards and loans?

The base rate also shapes borrowing and saving returns. Lenders can raise rates on credit cards, new bank loans and car loans when Bank hikes make funding more expensive — and cut them when policy loosens.

Savers get the upside. As of 3 November, Moneyfacts put the average easy access rate on a £10,000 balance at 2.56%, with easy access cash ISAs averaging 2.77%. Lock money away for a year and the average return rises to 4.47%. Rate changes particularly affect people who rely on savings interest to top up their income.

How does the UK compare globally?

The UK has run one of the highest rates in the G7 in recent years. The European Central Bank cut its main eurozone rate from an all-time high of 4% starting in June 2024, reaching 2% in June 2025 — then reversed course, raising to 2.25% in June 2026 in reaction to the Iran war and again to 2.5% in September.

The US Federal Reserve raised rates for the first time in three years at its September meeting — the third under new chair Kevin Warsh — lifting its target to 3.75%-4% from 3.5%-3.75%, after three cuts since September 2025. President Donald Trump had repeatedly attacked previous chair Jerome Powell for not cutting.

Warsh said the rise came because "inflation is too high and has been for too long," calling it a "sober" and "responsible decision." Trump backed Warsh after the announcement but labelled the Fed's rate-setting board "hostile."

The practical takeaway for UK households: with analysts pencilling in a further rise early next year, the window of cheap fixed-rate refinancing has closed, and roughly 800,000 borrowers a year coming off sub-3% deals are walking into a market priced near 6%.
