Policy experts warn Burnham against exceeding regional borrowing limits

Prime Minister Andy Burnham is likely to face pressure to raise taxes or cut public spending if he wants to fund new cost-of-living measures, according to a report published Wednesday by the Institute of Economic and Social Research (Niesr).

The institute said the government does not have enough fiscal headroom to rely on higher borrowing. Instead, it said ministers will have to make difficult choices across budgets to keep wider manifesto commitments on track.

Fiscal room narrows as inflation stays elevated

In the institute’s projections Niesr linked the constrained outlook to persistent inflation, which it said is being driven by the ongoing conflict in Iran. In the institute’s projections, inflation continues to rise until February 2027 and reaches a peak of 3.8 percent.

That path, the repoSources said, would also limit the speed and timing of monetary easing. Niesr’s assessment is that interest rate cuts are unlikely to begin until 2028, reinforcing the pressure on public finances through higher debt-servicing costs.

Debt management challenged by repeated economic shocks The repoSources said the current environment leaves the government with less scope to manage debt, which it described as having moved higher following successive economic shocks. With inflation remaining sticky and borrowing costs elevated, the institute argued that relying on additional debt would be difficult to justify within the fiscal constraints it described.

Niesr said this backdrop complicates efforts to introduce

Niesr said this backdrop complicates efforts to introduce new support measures aimed at the cost of living. It framed the policy choice as a trade-off: either find additional revenue, reduce spending elsewhere, or make structural changes that lower the long-run cost of existing commitments.

Reform options raised for welfare, pensions, and local taxation To reconcile competing pressures, the think tank pointed to several possible areas for reform, including the welfare bill, the pension triple lock, and council tax structures. The report did not present these as the only options, but as examples of policies that could be adjusted to create budget space without expanding borrowing.

The institute’s warning lands alongside the administration’s pledge not to increase income tax, VAT, or national insurance for working people. Niesr said that if structural reforms are not pursued, the government could ultimately face a choice between allowing debt to rise further or breaking those manifesto promises.

The report’s central message is that the combination of persistent inflation, delayed prospects for rate cuts, and limited fiscal capacity leaves little room for easy solutions. Niesr said the government will need to decide how to balance cost-of-living plans against the budget constraints it outlined.

Implications

Country Impact: Niesr says the government’s ability to add new cost-of-living initiatives is limited by tight fiscal capacity. The report points to difficult trade-offs between higher taxes, spending reductions, or structural reforms to maintain commitments.

Industry Impact: Any shift in welfare policy, the pension triple lock, or council tax structures could change the operating environment for public-service delivery and local authorities. The report frames these areas as potential sources of budget savings or rebalancing without additional borrowing.

Market Impact: The combination of persistent inflation and delayed interest rate cuts, as outlined by Niesr, suggests higher borrowing costs could remain a constraint in the near term. The report argues this limits scope for debt-funded policy expansion and increases pressure for budget-neutral measures.
