UK Public Sector Borrowing Hits £24.3 Billion in April, Highest Since 2020

UK public sector borrowing in April climbed to £24.3 billion, the largest sum for that month since 2020, according to official data. This total, an increase of £4.9 billion from a year prior, exceeded expectations and underscores the precarious fiscal landscape.

Separately, retail sales volumes experienced their sharpest decline in almost a year during April, primarily due to a surge in petrol prices impacting demand for motor fuel.

Economic Outlook Deteriorates

Ruth Gregory, deputy chief UK economist at Capital Economics, noted that the latest figures "highlight the deteriorating growth outlook and fragile fiscal backdrop that will face whoever is in 10 Downing Street".

Grant Fitzner, chief economist at the Office for National Statistics (ONS), explained that April's borrowing was "substantially higher" year-on-year because increased tax receipts were "more than offset by higher spending on benefits and other costs". Net social benefits rose by £2.7 billion, largely driven by inflation-linked increases to benefits and an earnings-linked rise in the state pension. Debt interest payments also hit a record high for April at £10.3 billion, up £0.9 billion from the previous year.

Geopolitical and Domestic Pressures

The escalation of the Iran war has prompted analysts to revise down UK economic growth predictions. Households face higher fuel bills, and the Bank of England is no longer anticipated to cut interest rates. Weaker economic growth is expected to result in slower increases in overall tax revenues, although the government may see additional income from taxes on petrol and North Sea oil and gas.

Borrowing costs, reflected in government bond yields, have risen since the conflict began. Financial markets suggest the Bank of England may need to increase rates to control inflation. While borrowing costs have generally increased for most governments following the Iran war, the domestic political uncertainty surrounding the leadership of the Labour party has also been cited as contributing to higher UK costs.

Rob Wood, chief UK economist at Pantheon Macroeconomics, estimated that "debt interest costs in 2026/27 will be about £15 billion higher than assumed in the Budget if gilt yields hold at current levels for the rest of the year". He added that "political risk" has further elevated the UK's borrowing costs, expecting them to remain "more elevated than they otherwise would be this year".

Government Response and Future Challenges

The government recently announced measures to counter the rising cost of living, including VAT cuts on family day out tickets, free bus journeys for under-16s in England during August, and reductions in import taxes on some basic foods. These initiatives are partially funded by changes to tax rules for certain UK-based oil and gas companies.

Dennis Tatarkov, senior economist at KPMG UK, warned that lower growth forecasts mean "public sector borrowing is likely to remain elevated in the medium term, potentially forcing the chancellor's hand to make more tweaks to fiscal policy at the time of the autumn Budget". The Office for Budget Responsibility's (OBR) forecast of £23.6 billion headroom against the government's borrowing rule was made before the Iran war, suggesting a less favourable current outlook.

Chief Secretary to the Treasury Lucy Rigby stated the government is "cutting borrowing and debt – with our actions reducing government borrowing by over £20 billion last year", emphasising the importance of fiscal rules amidst global instability. Shadow chancellor Mel Stride highlighted the record debt interest spending, linking it to market concerns over potential leadership changes. Liberal Democrat Treasury spokesperson Daisy Cooper criticised the figures as "a clear sign of this government's failure to get Britain's economy growing again", while Reform UK deputy leader Richard Tice blamed "wasteful overspending" and welfare.

ONS retail sales data showed a 1.3% fall in volumes for April, the largest monthly drop since May 2025, reversing a previous rise. This was led by a 10.2% decrease in motor fuel sales, suggesting "motorists were conserving fuel after stocking up in March". Clothing sales also declined, partly attributed to "variable weather conditions".
