IFS Warns Healey's Budget Paves Way for Brutal Spending Review 2026

The Institute for Fiscal Studies (IFS) has warned that John Healey's budget has paved the way for a "brutal" spending review next year, as it failed to cover a £28bn shortfall in the public finances needed to avoid a return to austerity.

The leading tax and spending experts said the chancellor had left himself a mountain to climb by ducking several big decisions in his debut tax and spending statement. The warning comes amid febrile bond markets and rising inflation, which is driving up the cost of delivering public services.

What the IFS Said About Healey's Budget

A day after Healey's address to the Commons, the IFS said the chancellor had left plans for overall departmental spending across the rest of the parliament broadly unchanged in cash terms. But with inflation surging, this effectively pencils in large cuts in the run-up to the next general election.

Helen Miller, director of the IFS, said avoiding a return to austerity for unprotected government departments could require a £17bn top-up to spending plans for 2030-31. That is before taking into account an additional £11bn needed to fund a commitment to increase defence spending to 3% of GDP.

"It effectively implies that some public services will see real-terms cuts in next year's spending review," she said. The IFS's intervention highlights the tough choices facing the government as it tries to balance the books while maintaining public services.

Why the £28bn Shortfall Matters

The £28bn shortfall is the gap between what the government needs to spend to maintain public services and what it has currently budgeted. Without additional funding, departments will face real-terms cuts, which could lead to a reduction in the quality and availability of public services.

This is particularly concerning given Labour's promise that there would be no return to austerity. The IFS's warning suggests that the government may struggle to keep that promise, especially with the additional pressure of rising defence spending.

The situation is complicated by the war in the Middle East, which has fuelled a surge in inflation. Higher inflation increases the cost of delivering public services, meaning that even maintaining current spending levels in cash terms amounts to a cut in real terms.

The Impact on Public Services and Austerity

If the spending review next year does not provide additional funding, unprotected government departments could see their budgets cut in real terms. This could lead to a return to austerity, with fewer resources for schools, hospitals, and other public services.

The IFS's analysis suggests that without a significant top-up, the government will have to make difficult decisions about where to allocate scarce resources. The £17bn needed for 2030-31 is just to avoid real-terms cuts for unprotected departments, and the £11bn for defence spending adds further pressure.

This could have political consequences, especially as Andy Burnham's government prepares for the next general election. Voters may hold the government accountable if public services deteriorate.

Key Takeaways from the IFS Analysis

• The IFS warns that Healey's budget leaves a £28bn shortfall, paving the way for a brutal spending review.
• Avoiding austerity for unprotected departments could require a £17bn top-up for 2030-31.
• An additional £11bn is needed to fund the commitment to increase defence spending to 3% of GDP.
• Rising inflation, partly driven by the Middle East war, is increasing the cost of public services.
• Labour's promise of no return to austerity is under threat.

Comparing Spending Plans and Needs

The table above summarises the key figures from the IFS analysis. The £28bn shortfall is the overall gap, while the £17bn and £11bn are specific top-ups needed to avoid cuts and meet defence commitments, respectively.

What to Watch Next

All eyes will be on the spending review next year, where the government will have to set out detailed departmental budgets. The IFS's warning puts pressure on the chancellor to find additional funding or face accusations of breaking Labour's promise on austerity.

With bond markets febrile and inflation high, the government's fiscal credibility is also at stake. Any sign that it is not serious about balancing the books could lead to higher borrowing costs, further squeezing public finances.
