IFS: budget will be ‘work of fiction’ without clear plan to cover UK’s £35bn spending pressures

Britain’s leading independent fiscal analysts have cautioned that the upcoming budget could lack credibility without explicit plans to manage substantial financial pressures facing public services. The Institute for Fiscal Studies raised concerns that failing to address approximately £35bn in spending demands would result in the appearance of unachievable spending commitments.

The financial challenges stem from multiple sources. Higher inflation triggered by the Middle East conflict has eroded the purchasing power of government budgets, forcing difficult choices about service quality and funding. Additionally, the government’s commitment to increase defence spending to 3% of GDP by 2030 adds to these pressures. The institute calculated that adequately compensating for inflation while meeting defence pledges would require either tax increases or benefit reductions totaling around £35bn.

The IFS emphasized that the chancellor faces a fundamental decision: either increase funding for existing service commitments, accept real-terms cuts to departmental budgets, or delay decisions until a subsequent spending review. The thinktank warned that simply leaving spending totals unchanged while inflation eats away at their value would implicitly constitute a choice to reduce service quality or quantity, whether the government explicitly intended this or not.

The fiscal environment has grown more challenging following market volatility linked to international developments. Bond market turbulence has increased government borrowing costs, potentially reducing the chancellor’s fiscal flexibility by approximately £4bn by 2029-30, though higher inflation would provide some offsetting tax revenue gains. The IFS director stated that setting out unrealistic plans without intention to deliver them would undermine governmental credibility with financial markets and the public.

The Treasury responded that the chancellor remains committed to fiscal discipline and meeting established fiscal rules, noting that updated forecasts would be published alongside the budget later this month.
