Chancellor Rachel Reeves will deliver her Budget on Wednesday against a backdrop of rising unemployment and higher-than-forecast Government borrowing, but amid signs this year’s spike in inflation may have peaked.

Here, the PA news agency looks at five key economic indicators that are likely to shape both the content and the tone of Ms Reeves’ speech.

– Borrowing

Government borrowing for the current financial year is running at a higher level than forecast and is the highest on record outside the Covid-19 pandemic.

Borrowing stood at £116.8 billion for the seven months from April to October 2025, according to figures published last week by the Office for National Statistics (ONS).

This is £9.9 billion more than the £106.9 billion forecast for this period by the Office for Budget Responsibility (OBR) in March.

It is also the second-highest borrowing figure for April-October since comparable data began in 1993, behind only 2020.

The Government has overshot forecasts this year due to “a combination of lower-than-expected tax receipts and higher-than-expected borrowing by councils and other bodies outside of central government control”, according to the Institute for Fiscal Studies think tank.

It means that when the OBR publishes its new economic forecasts alongside the Budget on Wednesday, total borrowing for the current financial year is likely to be revised up, as it may be for subsequent years.

It is not unusual for a government to borrow in order to spend more than it receives in taxes and other income.

The last time the government spent less than it received was 25 years ago, in 2000/01.

However, borrowing is now running at a comparatively high level and the latest figures are a reminder of how economic forecasts can be subject to a lot of uncertainty.

Should borrowing continue to be higher than expected, Rachel Reeves may need to find additional ways to ensure she has enough “headroom” in her Budget to balance the nation’s finances.

– Economic growth

The OBR’s new forecasts on Wednesday are also likely to include revised estimates for economic growth in the UK.

Growth in 2025 has slowed as the year has gone on.

The size of the economy grew by 0.7% in January-March, by 0.3% in April-June and by just 0.1% in July-September, according to estimates by the ONS.

In addition, the economy is estimated to have contracted by 0.1% in September, driven by a fall in motor manufacturing due partly to the cyber attack on Jaguar Land Rover.

The OBR’s current forecast for growth across the whole of 2025 – published back in March – is 1.0%, rising to 1.9% in 2026.

The UK has recorded annual growth of less than 1% only five times in the past 30 years: in 2008 and 2009 (zero and -4.6% respectively, during the financial crash); 2011 (0.9%), 2020 (-10.0%, during the pandemic) and 2023 (0.3%).

The Chancellor already knows the new GDP forecast for 2025 and this will undoubtedly shape some of the tone of her Budget speech.

Responding earlier this month to the GDP figures for July-September, Ms Reeves said: “We had the fastest-growing economy in the G7 in the first half of the year, but there’s more to do to build an economy that works for working people.

“At my Budget later this month, I will take the fair decisions to build a strong economy that helps us to continue to cut waiting lists, cut the national debt and cut the cost of living.”

– Inflation

The UK’s overall rate of inflation stood at 3.6% last month, down from 3.8% in September, but above the Bank of England’s target of 2%.

It was the first time the rate had fallen month on month since May, suggesting inflation this year may have peaked.

The figure – based on the ONS Consumer Prices Index – is a measure of how much prices have risen on average year on year.

A fall from 3.8% to 3.6% means prices are not rising quite as fast as they were.

Any evidence that the cost of living is easing is good news for the Government and the latest figures will almost certainly be welcomed by Ms Reeves during her speech.

It could also mean the Bank of England is more likely cut interest rates from their current level of 4%, when it makes its next decision in December.

The Bank of England’s own forecasts suggest inflation is on track to fall to the 2% target by 2027.

This would mark a return to relatively low inflation in the UK and the end of a turbulent few years that saw the rate hit 11.1% in autumn 2022.

– Unemployment

Estimates of unemployment in the UK are produced by the ONS but are currently not classed as official statistics.

This is because the figures are based on a survey that has had a low response rate since the pandemic, meaning the data is unreliable and has to be treated with caution.

The trend suggested by the latest figures is that unemployment has risen over the past year, from 4.3% of people aged 16 and over in July-September 2024 to 5.0% in July-September 2025.

This is the highest rate outside the Covid-19 pandemic since 2016.

The OBR’s current forecast for the unemployment rate across 2025 is 4.5% and, given the data from the ONS, it seems likely this figure will be revised upwards on Wednesday.

Rising unemployment is not a backdrop any chancellor would choose for a Budget speech, especially given the confusion over how many people may or may not be out of work.

The unreliability of the unemployment figures has been criticised by many economists and statisticians – including Bank of England governor Andrew Bailey.

Ms Reeves is also facing other signs that point to a weakening jobs market, with the number of people on employee payrolls falling in most of the last 12 months, along with a slowdown in wage growth.

However, the proportion of the workforce classed as economically inactive – who are of working age and not in employment but not currently looking for work – has fallen slightly.

It stood at an estimated 21.0% in July-September 2025, down from 21.6% in the same period a year earlier.

– Retail sales

Lastly, the Chancellor is sure to have noted the latest retail sales figures.

The volume of sales fell 1.1% in October, the first monthly drop since May, according to the ONS.

It follows a strong rise of 0.7% in September, but the fall was larger than economists had forecast and could point to consumers being cautious with their money ahead of the Budget.

There was some feedback from retailers that people were waiting for November’s Black Friday deals, the ONS added.

Rob Wood, chief UK economist at Pantheon Macroeconomics, said: “We expect retail sales volumes growth to remain subdued in November as pre-Budget speculation reaches a fever pitch.

“We still think consumers should return to the high street when the Budget is passed and there is a little more clarity over fiscal policy.”

Some clarity should come on Wednesday, when the Chancellor gets to her feet in the House of Commons to deliver one of the most keenly-awaited Budgets in recent years.
