UK Chancellor John Healey is preparing a cautious first budget, with fiscal headroom under pressure from higher borrowing costs and new spending commitments ahead of a planned October 28 announcement.
The government inherited a £23.6 billion fiscal headroom against its borrowing rule, but that buffer is estimated to shrink by around £9 billion due to rising debt-servicing costs and additional expenditure commitments. The yield on 30-year UK government debt has increased to approximately 5.79% from 5.75%, reflecting elevated borrowing costs.
Defense spending remains a key fiscal challenge. Current expenditure stands at about 2.6% of gross domestic product, with plans to raise it to 3.5% of GDP in the 2027 spending review. Meeting a 3% defense spending target by 2030 would require an additional £10 billion in funding, according to estimates.
Healey has emphasized fiscal discipline, mandating that all spending announcements include funding sources. The government is also exploring whether fiscal rules permit increased infrastructure borrowing without breaching targets. Potential revenue measures under consideration include higher taxes on banks, given their recent strong profits, and increased levies on windfall profits at fossil fuel companies such as BP.
BP reported more than doubling its profit between April and June amid elevated oil prices, underscoring the revenue potential of higher taxes on the sector. The budget represents Healey’s first major fiscal test as the Labour government, led by Prime Minister Andy Burnham, seeks to maintain its recovery in opinion polls while balancing economic pressures.
