Rachel Reeves Wrecked the UK Economy – But She’s Saved Her Nastiest Surprise Until Last
Rachel Reeves leaves behind a deeply complicated economic legacy. Her supporters can point to stronger-than-expected growth, falling borrowing in some periods and a series of investments designed to improve Britain’s long-term prospects. Her critics, however, see something very different: higher taxes, weak productivity, stubborn inflation, rising debt and a Treasury with painfully little room for manoeuvre.
And now comes the twist.
The most uncomfortable part of Reeves’s economic legacy may not be what she did while Chancellor. It may be what the next government has been left to deal with after she departed.
Britain’s public finances have just delivered a nasty warning. In July 2026, the government unexpectedly recorded a £1.8 billion borrowing deficit, despite unusually strong self-assessed income-tax receipts. The shortfall was considerably worse than economists had expected and pushed total borrowing for the financial year to £56.7 billion, £2.3 billion above the Office for Budget Responsibility’s forecast.
For Prime Minister Andy Burnham and Chancellor John Healey, the timing could hardly be worse.
Their first Budget is approaching, and the Treasury needs to finance an ambitious political programme while dealing with debt approaching £3 trillion, elevated borrowing costs and a shrinking amount of fiscal headroom.
This is where Reeves’s final surprise begins to look rather less like a political footnote and rather more like a financial time bomb.
The economy is not actually in ruins
There is an important problem with the claim that Reeves simply “wrecked” the UK economy.
The latest evidence does not support such an uncomplicated conclusion.
Britain’s economy grew by 0.6 per cent in the first quarter of 2026, making it the fastest-growing economy in the G7 during that period. Reeves seized on the figures as evidence that her strategy was beginning to work, while the International Monetary Fund subsequently upgraded its forecast for Britain.
More recently, the economy expanded by 0.4 per cent in the second quarter, while indicators of services activity and consumer confidence showed further signs of improvement.
So the argument is not that Reeves presided over an economic catastrophe in the conventional sense.
The more interesting question is whether the improvements came at a price.
And that price may now be landing on Burnham’s desk.
The tax burden became the defining feature
Reeves entered the Treasury promising economic stability and an end to what Labour described as the chaos of the previous Conservative government.
Her first major Budget, however, involved around £40 billion in tax increases. Reeves argued that the measures were necessary because the public finances were in a worse condition than Labour had anticipated and because the government needed to finance public services.
The political problem was immediate.
Britons were told that higher taxes were necessary to create stability and eventually generate growth. But businesses and households still had to absorb the additional costs.
For companies, higher employment costs and taxes created concerns about investment and hiring.
For households, tax rises and frozen thresholds threatened to reduce disposable income.
For the government, meanwhile, the additional revenue was never going to solve every problem.
That is because Britain’s spending commitments are enormous.
Pensions are expensive. The NHS requires huge sums. Defence spending is under pressure. Local authorities are struggling. Debt interest absorbs substantial amounts of taxpayers’ money.
A government can raise taxes, but it cannot tax its way out of every structural problem.
And then came the productivity problem
One of Reeves’s biggest headaches was productivity.
For years, Britain has struggled to generate the kind of sustained productivity growth that would allow wages and living standards to rise rapidly without creating inflationary pressure.
The OBR’s pessimistic productivity assumptions forced Reeves into difficult choices. But now an intriguing development has emerged: new research suggests that some of the gloomy productivity data may have been misleading.
A recent analysis from the Centre for Economic Performance at the London School of Economics found evidence that UK productivity may have been growing at around 1.6 per cent annually since mid-2024, considerably faster than earlier estimates. The research suggested that weaknesses in the Labour Force Survey may have distorted the picture.
That matters enormously.
If productivity was stronger than Reeves believed, some of the painful fiscal decisions made on the basis of weaker forecasts may have been unnecessarily restrictive.
But there is a darker implication.
The government has already made decisions based on the data it had available at the time.
You cannot simply rewind the Budget.
You cannot return taxes once they have been collected.
And you cannot easily reverse spending decisions once expectations have been created.
The real surprise may be fiscal headroom
Perhaps the nastiest inheritance is not a single tax or spending measure.
It is the disappearance of fiscal flexibility.
Before Burnham’s government arrived, Britain’s fiscal headroom was already under pressure. Rising gilt yields, inflation and higher debt-servicing costs have made borrowing more expensive. Recent estimates put the government’s remaining room against its fiscal rules at somewhere around £10 billion to £15 billion, although the precise figure is highly sensitive to economic forecasts.
That is an astonishingly small cushion for a country with a debt burden approaching £3 trillion.
And Burnham has promised plenty.
He wants to reduce household energy costs.
He wants cheaper buses.
He wants greater regional investment.
He wants to tackle rough sleeping.
He wants to expand his programme of devolution.
He wants stronger public services.
All of those things cost money.
The Treasury’s answer has been increasingly blunt: new commitments need to be paid for by savings elsewhere.
That means Burnham may soon discover that his government’s greatest opponent is not sitting on the opposition benches.
It is sitting inside the spreadsheet.
Reeves’s critics will say: “We told you so”
This is where the political consequences become particularly uncomfortable.
Conservatives and other opposition parties can now argue that Labour’s tax-and-spend strategy has left the country with higher debt and insufficient room to respond to new problems.
But the argument is not quite that simple.
Reeves herself spent much of her time insisting that fiscal discipline was essential. She repeatedly argued that Labour’s policies were designed to create economic stability and that borrowing would fall over the course of the Parliament. In one statement earlier this year, she highlighted the fact that borrowing had fallen by £20 billion compared with the previous year.
Her supporters therefore have a strong counterargument.
The economic problems facing Burnham are not entirely Reeves’s creation.
Some are structural.
Some are global.
Some are the consequence of higher interest rates.
Some are connected to international instability.
And some are simply the accumulated cost of decades of difficult political choices.
Yet political responsibility does not work like an economics textbook.
The person who inherits the problem still has to solve it.
The October Budget could expose everything
John Healey’s first Budget, scheduled for October 28, could therefore become the moment when Reeves’s legacy is properly tested.
Healey needs to satisfy financial markets.
He needs to fund Burnham’s commitments.
He needs to address defence spending.
He needs to maintain confidence in the government’s fiscal rules.
And he needs to avoid making tax increases so unpopular that the new government begins its premiership looking indistinguishable from the government it replaced.
That is an extraordinarily difficult balancing act.
There is already speculation about tax rises and targeted levies, including potential measures affecting banks and energy companies.
But raising taxes carries its own risks.
JPMorgan chief executive Jamie Dimon has already warned against higher bank taxes, arguing that Britain risks damaging its competitiveness and encouraging financial-sector jobs to move elsewhere.
So even supposedly easy tax targets come with economic consequences.
The irony is that Reeves may eventually look better
There is another possibility — and it is one that her critics may find particularly irritating.
If Burnham’s government struggles with the public finances, Reeves’s reputation could improve retrospectively.
Politicians are often judged differently once they leave office.
A Chancellor who appears excessively cautious at the time can later be remembered as the person who understood the dangers.
If Healey has to raise taxes, cut spending or abandon parts of Burnham’s programme, Reeves’s warnings about fiscal discipline may suddenly seem considerably more reasonable.
That would be an extraordinary reversal.
The politician accused of wrecking the economy could eventually become the politician who warned everyone about the consequences.
But Reeves still carries responsibility
None of this means Reeves should be absolved of criticism.
Her economic strategy was controversial.
The tax burden increased.
Growth forecasts were repeatedly revised.
Productivity remained disappointing in official assessments.
And the government’s fiscal position remains vulnerable to shocks.
Even the March 2026 outlook saw the OBR reduce its forecast for annual growth to 1.1 per cent, while expecting unemployment to rise to 5.3 per cent before improving later.
Those are hardly figures that justify triumphant claims of economic transformation.
But nor do they justify saying Britain has been economically destroyed.
The reality is more uncomfortable.
Reeves inherited a difficult economy.
She made controversial choices.
Some of those choices may prove defensible.
Others may prove costly.
And some of the assumptions behind them may now be turning out to have been wrong.
The final verdict is still to come
Rachel Reeves may have left the Treasury, but her economic story is nowhere near finished.
The strongest evidence suggests that Britain is neither the economic disaster her fiercest critics describe nor the spectacular success her supporters sometimes portray.
It is an economy with genuine strengths and serious vulnerabilities.
Growth has surprised on the upside.
Productivity may be stronger than previously thought.
Consumer confidence has improved.
But debt remains enormous, borrowing costs are uncomfortable, fiscal headroom is limited and the government faces a long list of expensive commitments.
That is the real “nastiest surprise” Reeves may have left behind.
Not a secret tax.
Not a hidden Budget measure.
Not one final political ambush.
It is something much more difficult to escape: a government with ambitions that are far larger than its financial room for manoeuvre.
Burnham now has to make the numbers work.
Healey has to find the money.
And Reeves, having left the Treasury, can watch from the sidelines as her successors discover just how unforgiving Britain’s public finances can be.
If the October Budget forces painful choices, the new government may spend months blaming the inheritance.
But eventually, the excuses will run out.
And that is when the real judgment on Rachel Reeves’s economic legacy will begin.
