Government borrowing in May hit the highest since the Covid crisis but was lower than the UK’s fiscal watchdog had forecast.
Borrowing reached £15bn last month, which was £800m higher than May last year.
It means that the public sector spent more than it received in taxes and other income, leading the government to borrow billions of pounds.
It is the third highest figure for May since records began in 1993, surpassed only by the pandemic years.
However, borrowing was £600m less than the Office for Budget Responsibility (OBR) had expected.
With the general election fast approaching, whichever party wins will face similar challenges on tax, spending and debt, economists have warned.
“Government borrowing holds steady but the fiscal Pandora’s box awaits for the next chancellor”, said Michal Stelmach, senior economist at KPMG UK.
“Interest rates are set to remain higher, debt more difficult to bring down and spending pressures continue to mount.”
While there were some “bright” spots in May’s borrowing figures, according to Simon Wells, chief European economist at HSBC, he pointed out that government debt was at an “extraordinary” level – and the highest since the 1960s.
Government debt as a percentage of UK economic output – commonly known as gross domestic product – was at 99.8% last month.
Mr Wells told BBC Radio 4’s Today programme: “What has happened is public sector debt has ramped up, first through the global financial crisis and then again through Covid so it is at historically high levels.”
High levels of debt means that public sector finances are “vulnerable” to higher interest rates which makes repayments more costly. Mr Well warned that large debt leaves less “headroom” to deal with any future crisis.
The Bank of England had been raising interest rates in an effort to bring down UK inflation but one knock-on effect of this is the government having to pay more interest on debt.
Last month, the interest payable on central government debt was £8bn which was one of the highest amounts on record.
