Reeves touts improving outlook, but watchdog warns UK’s fiscal cushion is thin as energy shocks hit markets

As Rachel Reeves told lawmakers that “inflation is down, borrowing is down, living standards are up and the economy is growing,” share prices in London were registering their steepest one-day fall in nearly a year and gas prices were jumping to three-year highs.

The chancellor’s first full Spring Statement-style event on March 3 was carefully staged to project stability. But the official forecasts released alongside it point to a more fragile picture: slower growth this year, higher unemployment, a record tax burden and only a narrow buffer against new shocks just as conflict involving Iran pushes global energy markets higher.

Growth downgraded, unemployment set to rise

The Office for Budget Responsibility (OBR), the United Kingdom’s independent fiscal watchdog, cut its forecast for real gross domestic product growth in 2026 from 1.4% to 1.1%. It now expects unemployment to peak at 5.3% next year, up from a 4.9% peak in its November projections.

At the same time, borrowing is projected to fall faster than expected, giving Reeves slightly more room to meet her self-imposed debt rules—a cushion the OBR warns could be quickly eroded if energy prices remain elevated.

“The conflict could have very significant impacts on the global and U.K. economies,” the watchdog said in its March Economic and Fiscal Outlook, referring to the escalation of hostilities involving Iran and U.S.-led forces in the Middle East.

Because its central forecast was closed before the latest surge in oil and gas prices, the OBR treated the situation as a downside-risk scenario rather than building it into its baseline.

Markets react as energy prices jump

By the close of trading on March 3, that risk was already being priced.

• The FTSE 100 fell about 2.75%, its largest one-day decline in 11 months.
• U.K. natural gas contracts for the month ahead jumped around 21% to 30%, reaching levels not seen in three years.
• Brent crude rose more than 6% to roughly $82.50 a barrel.
• 10-year gilt yields climbed back above 4.5%, as investors bet the Bank of England may keep interest rates higher for longer to guard against a renewed inflation spike.

Reeves opened her statement to the House of Commons by acknowledging “the unfolding conflict in Iran and the Middle East,” and pledged to “chart a course through that uncertainty, secure our economy against shocks and protect families from the turbulence we see beyond our borders.” But she announced no major new tax or spending measures, delivering what she has rebranded as a “Spring Forecast” rather than a second Budget.

A quieter fiscal event—by design

The chancellor has pledged to hold only one substantial fiscal event a year, in the autumn, after years in which successive chancellors used spring and autumn statements to unveil significant changes. The move is aimed at reassuring markets after the turmoil that followed the 2022 “mini-budget” introduced by then-Prime Minister Liz Truss and Chancellor Kwasi Kwarteng.

Analysts at the Institute for Government, a nonpartisan think tank, said Reeves “stuck to her commitment to avoid making news,” describing the low-key approach as a return toward international best practice in budget-making.

Inflation easing, but energy risks loom

The OBR expects consumer price growth to ease from 3.4% in 2025 to 2.3% in 2026, then fall back to the Bank of England’s 2% target from 2027 onward.

The Treasury says earlier decisions—freezing rail fares, extending a 5 pence-a-litre cut in fuel duty, providing £150 off household energy bills and holding prescription charges—will together trim inflation by about 0.4 percentage points in 2026–27.

Ratings agency Moody’s and other analysts have cautioned, however, that sustained higher energy prices linked to the Iran conflict could slow disinflation and delay interest-rate cuts.

Youth unemployment emerges as a key vulnerability

Overall unemployment is expected to rise from around 4.75% in 2025 to a peak of 5.3% in 2026 before gradually declining to about 4.1% by 2030. The OBR says much of the softness reflects new entrants to the labor force struggling to find jobs rather than widespread layoffs.

Among young people, the situation is more severe. The jobless rate for 16- to 24-year-olds has climbed to about 16%, approaching an 11-year high. Analysts attribute that to weaker hiring and higher employment costs following increases in the national minimum wage and employer contributions.

Think tanks say tackling youth unemployment will test the government’s promises on opportunity and skills, and expect Reeves to outline more detailed policy on apprenticeships and training in a forthcoming Mais lecture on economic policy.

Living standards: improving on average, uneven in practice

Reeves sought to highlight improving living standards, pointing to OBR figures showing GDP per head rising by about 5.6% over the course of this Parliament after falling during the last one. Treasury officials say that by the time of the next general election, expected in 2029, real household disposable income per person will be more than £1,000 a year higher than in the previous Parliament.

“After the toughest cost-of-living crisis in a generation, we are finally seeing real wages rising and families starting to feel the benefit,” Reeves said.

Economists note that such averages mask wide variation. Households with mortgages stand to gain from lower interest rates; Reeves said a typical new fixed-rate mortgage now costs more than £1,300 a year less than at the time of the 2024 election. Renters and those out of work—particularly younger people and low-income families—are less likely to feel an improvement soon.

Borrowing falls, but debt remains near historic highs

The OBR projects public sector net borrowing falling from about 5.2% of GDP in 2024–25 to 4.3% this year, then to 3.6%, 2.9%, 2.5% and finally 1.6% of GDP by 2030–31. Over the forecast horizon, borrowing is nearly £18 billion lower than expected in November, largely because falling inflation has reduced the cost of servicing index-linked debt and tax receipts have proved more resilient.

Public sector net debt, however, is set to remain close to historic highs. It is forecast to rise from around 94.5% of GDP in 2025–26 to a peak of about 96.5% in 2028–29, then edge down to roughly 95% by 2030–31.

The OBR notes that U.K. public debt has almost tripled as a share of GDP over the past two decades, and that debt interest payments have more than doubled since 2019–20 to about 3.6% of GDP.

Fiscal rules met—for now

Reeves has bound herself to fiscal rules requiring that public sector net debt be falling as a share of GDP in the fifth year of the forecast and that borrowing stay within set limits. The OBR judges those rules are currently met, with what it estimates as about £23.6 billion of “headroom” in 2030–31 against the debt target—slightly more than the £21.7 billion buffer estimated in November.

Several economists caution that the extra room is narrow and may prove short-lived. Pressures are building in multiple areas, including health, disability and incapacity benefits, local government finances and defense, where the government has signaled support for higher spending over the coming decade.

An expansion of funding for special educational needs and disabilities—including £3.5 billion of extra money for the Department for Education in 2028–29 and associated sums for devolved administrations—was one of the few specific measures referenced in the Spring Statement.

Record tax burden does the heavy lifting

The OBR projects the overall tax take to rise to about 38% to 38.5% of GDP by 2030–31, the highest share on record for the United Kingdom and up from around 33% in the mid-2010s.

Members of the watchdog’s Budget Responsibility Committee have said roughly two-thirds of that increase is the result of frozen income tax thresholds, which pull more earners into higher bands as nominal wages grow, rather than explicit rises in tax rates.

A strategy tested by shocks beyond Westminster

For now, Reeves is betting that a cautious, rules-based approach and a single big Budget each year will be enough to reassure investors and voters in an era of repeated external shocks. The durability of that strategy may depend less on the charts she presented in Parliament than on events thousands of miles away—and on whether the fiscal room she has gained on paper survives the next turn in global energy markets.
