UK government borrowing in April hit its highest level since the height of the Covid pandemic, official figures confirmed this week, rattling financial markets and handing the opposition fresh ammunition against Chancellor Rachel Reeves’s fiscal management. The Office for National Statistics recorded borrowing significantly above forecast, driven by a combination of higher debt interest payments, rising public sector pay costs, and weaker-than-expected tax receipts. The figure arrived just as the Labour government was attempting to present its economic stewardship as responsible and sustainable — and just weeks before a spending review that was already expected to be difficult. The pound dipped and gilt yields edged higher in the immediate aftermath, though both settled before close.
The received wisdom
The mainstream centre-left framing is that the numbers reflect structural inheritances from the previous Conservative government rather than Labour policy choices. Thirteen years of chronic underinvestment in public services, the Liz Truss mini-budget that sent interest rates spiralling, and a public sector pay gap that reached crisis point under the Tories — all of these, on this account, land on Reeves’s desk as baseline pressures that any incoming government would face. The progressive version goes further: borrowing to invest is economically rational when the alternative is continued public service degradation; the markets that periodically panic about UK debt are the same markets that were comfortable funding US deficits of comparable scale for decades. Austerity, the argument runs, has been tried and found wanting. What is needed is a serious industrial strategy and a growth agenda, not a return to spending restraint that failed to deliver solvency the first time.
A different read
The “inheritance” framing has grown thin through repetition. The BBC’s reporting on the April borrowing numbers came alongside coverage of a Labour government that has been in office for nearly a year, raised employer National Insurance contributions in ways that independent forecasters say will dampen hiring, and has yet to produce a credible medium-term fiscal path that does not rely on optimistic growth assumptions or redefine what counts as investment spending.
The structural argument for borrowing-to-invest is sound in principle but requires a theory of the investment. Borrowing to fund genuinely productivity-enhancing infrastructure — grid upgrades, housing supply, transport connectivity in second-tier cities — can generate returns that service the debt. Borrowing to fund current account spending on public sector wages, or to maintain a welfare state that was designed for demographics that no longer exist, does not have that profile. The uncomfortable question for Labour, as it was for the Conservatives before them, is which category most of the actual spending falls into.
There is also a longer historical pattern worth naming. The UK has been running structural current account deficits for most of the past two decades, across governments of both parties. The explanation that each side reaches for is that the other party created the problem, but the persistence of the deficit across multiple administrations and ideological flavours suggests something deeper: a political culture in which no government has been willing to tell voters that the public services they expect and the tax burden they are prepared to accept are not in equilibrium. Thatcher cut some things and borrowed for others; Blair borrowed and called it investment; Osborne cut and called it structural reform while missing most of his own targets; Truss cut catastrophically; Sunak stabilised at the cost of visible public service deterioration. Reeves inherited an impossible position but is also reaching for the same rhetorical toolkit as her predecessors.
The markets are a lagging indicator here. The gilt market has not yet priced in the risk of a genuine UK fiscal credibility problem, partly because the US deficit situation provides constant comparison comfort and partly because the Bank of England’s inflation-fighting credibility provides a floor. But the April numbers are a reminder that the floor has a price, and that the cost of debt service is now the fastest-growing line item in public expenditure — a dynamic that, left unaddressed, crowds out exactly the investment spending that Labour is banking on to generate the growth that makes the numbers add up.
What to watch
Watch the spending review in June: the allocations will reveal whether the government is genuinely accepting the constraint or hoping that growth materialises fast enough to make the constraint irrelevant. Watch gilt yields through the summer — if they drift meaningfully above 5% on 10-year paper, the conversation about fiscal credibility will become unavoidable rather than opposition noise. And watch whether Reeves makes any move to revisit the employer NI increase in response to weaker-than-expected labour market data; a reversal would be a significant concession that the growth assumptions built into the Budget were wrong.
