Why is UK inflation still high?

- Published
Prices in the UK rose by 3.8% in the year to September, matching the rate recorded in July and August.
It means inflation remains well above the Bank of England's 2% target.
The Bank moves interest rates up and down to try to keep inflation at that level. It has cut rates five times since August 2024 to bring rates down to 4%.
What is inflation?
Inflation is the increase in the price of something over time.
For example, if a bottle of milk costs £1 but is £1.05 a year later, then annual milk inflation is 5%.
How is the UK's inflation rate measured?
The prices of hundreds of everyday items, including food and fuel, are tracked by the Office for National Statistics (ONS).
This virtual "basket of goods" is regularly updated to reflect shopping trends, with virtual reality headsets and yoga mats added in 2025, and local newspaper adverts removed.

The ONS monitors price changes over the previous 12 months to calculate inflation.
The main inflation measure is called the Consumer Prices Index (CPI), external, and the latest figure is published every month.
What is happening to UK inflation?
CPI was 3.8% in the year to September 2025, the same as in the 12 months to July and August.
This figure is the highest recorded since January 2024, when the rate was 4%.
However, inflation remains well below the 11.1% figure reached in October 2022, which was the highest rate for 40 years.

The Bank also considers other measures such as "core inflation" when deciding whether and how to change rates.
This doesn't include food or energy prices because they tend to be very volatile, so can be a better indication of longer term trends.
Core CPI was 3.5% in the 12 months to September, down slightly from 3.6% recorded in the year to August.
Why are prices still rising?
Although inflation has fallen significantly since the October 2022 high, that doesn't mean prices are falling - just that they are rising less quickly.
Inflation soared in 2022 because oil and gas were in greater demand after the Covid pandemic, and energy prices surged again when Russia invaded Ukraine.
It then remained well above the 2% target partly because of higher food prices.
These continue to be a significant factor in the current inflation figures.
In August, food price inflation had risen for the fifth month in a row to stand at 5.1%. Economists said supermarkets were passing on the cost of government increases in the minimum wage and National Insurance Contributions to shoppers through higher prices.
However, inflation for food and non-alcoholic beverages was down in the year to September at 4.5%. September's figure also reflected a smaller fall in petrol prices and airfares than in the same period last year.
Why does putting up interest rates help to lower inflation?
When inflation was well above its 2% target, the Bank of England increased interest rates to 5.25%, a 16-year high.
The idea is that if you make borrowing more expensive, people and businesses have less money to spend. People may also be encouraged to save more.
In turn, this reduces demand for goods and slows price rises.
But it is a balancing act - increasing borrowing costs risks harming the economy.
For example, homeowners face higher mortgage repayments, which can outweigh better savings deals.
Businesses also borrow less, making them less likely to create jobs. Some may cut staff and reduce investment.
In recent months, inflation has remained above the Bank's target at the same time as the economy has remained relatively flat and the jobs market has softened.
Therefore, the Bank has chosen to cut rates, despite high inflation, in an attempt to encourage people to spend more and get businesses to invest and create jobs to boost the economy.
What is happening to UK interest rates and when will they go down again?
The Bank of England began cutting rates in August 2024, and has made five cuts to bring the rate down to 4%, where they have remained.
Bank of England governor Andrew Bailey has repeatedly said that future cuts would be made gradually and carefully.

At the Bank's November meeting, rate setters voted 5-4 to hold rates at 4%,
That had been widely predicted, given that inflation is still above the Bank's target.
Bank governor Andrew Bailey said he would "prefer to wait and see" whether price rises continue to ease during the rest of 2025.
Economists think the vote split means a cut at the Bank's next meeting on 18 December is reasonably likely.
But that decision will be made after the Budget on 26 November, so will depend in part on what Chancellor Rachel Reeves announces.
She has not ruled out raising income tax, National Insurance or VAT - a move that would breach the manifesto pledge Labour issued before the 2024 general election.
The Bank also has to consider the wider global economy. Mr Bailey has repeatedly warned about the unpredictable impact of US tariffs.
Are wages keeping up with inflation?
The latest official figures, external show that regular pay in Great Britain grew by more than inflation between June and August.
Average annual growth in pay (excluding bonuses) during the three-month period was 4.7%, down from 4.8% in the three months to July.
After taking inflation into account, wages grew by 0.9% between June and August.

Annual average regular earnings growth was 6% for the public sector and 4.6% for the private sector.
Meanwhile, separate ONS figures showed, external the estimated number of vacancies in the UK fell by 9,000 (1.3%) to 717,000 between July and September 2025.
Vacancy numbers have now dropped compared with the previous three months for more than three years.
The unemployment rate was 4.8% in the three months to, external August - up from 4.7% in the three months to July and the three months to June.
This the highest figure since June 2021, which will also factor into the Bank of England's rate decisions.
What is happening to inflation and interest rates in Europe and the US?
The US and EU countries have also been trying to limit price increases, but both have lower central bank interest rates than the UK.
The inflation rate for countries using the euro was 2.2% in September, up from 2% in August, according to EU data, external.
In June 2024, the European Central Bank (ECB) cut its main interest rate from an all-time high of 4% to 3.75%, the first fall in five years.
By June 2025, after several further cuts, its key rate stood at 2%, where it has remained.
Inflation in the US rose to 3% in September, up from 2.9% in August, and above the US central bank's 2% target.
In October, the Federal Reserve said it was lowering the target for its key lending rate by 0.25 percentage points, which put it in a range of 3.75% to 4%.
The move was the bank's second rate cut in a row, after holding for most of 2025, and is expected to bring down borrowing costs across the US.
The Fed has repeatedly come under attack from US President Donald Trump for not cutting rates.
