UK April Borrowing Jumps to £24.3bn, Debt Interest Hits Record £10.3bn

*TL;DR UK public‑sector borrowing surged to £24.3 bn in April, a £4.9 bn YoY rise, while debt‑interest payments hit a record £10.3 bn as retail sales fell 1.3%.

Context April’s borrowing level is the highest for the month since the Covid pandemic began in 2020. The Office for National Statistics (ONS) defines borrowing as the gap between government spending and tax receipts. Higher spending on benefits and other costs more than offset the rise in tax receipts.

Key Facts - Borrowing reached £24.3 bn, up £4.9 bn from April 2023 and above analysts’ forecasts. - Debt‑interest outlays climbed to £10.3 bn, a £0.9 bn increase YoY, setting a new monthly record. - Retail sales volumes slipped 1.3% in April, the steepest decline since May 2025, driven by a 10.2% plunge in motor‑fuel sales. - Net social benefits rose £2.7 bn, largely from inflation‑linked adjustments and the earnings‑linked rise in the state pension. - Government bond yields have risen since the Iran‑related oil price shock, pushing gilt (UK government bond) yields toward 4.5%, a level that could add roughly £15 bn to debt‑service costs in 2026/27 if sustained. - The FTSE 100 (^FTSE) slipped 0.4% on the day the borrowing data were released, while the iShares Core UK Gilts ETF (ticker: IGLT) gained 1.2% as investors priced higher borrowing costs.

What It Means The borrowing surge signals a widening fiscal gap that the Treasury must bridge without breaching its rule against day‑to‑day borrowing. Higher benefit payments and record‑high interest costs tighten the fiscal space, limiting room for further stimulus. Ruth Gregory, deputy chief UK economist at Capital Economics, warned that the numbers “highlight a deteriorating growth outlook and fragile fiscal backdrop for whoever occupies 10 Downing Street.” The ONS chief economist, Grant Fitzner, echoed the concern, noting that higher tax receipts were “more than offset by higher spending on benefits and other costs.” Retail‑sales weakness underscores consumer pressure from rising fuel prices and a broader cost‑of‑living squeeze. The 10.2% drop in motor‑fuel sales suggests motorists are curbing mileage after a March stock‑up, a trend that could dampen economic activity further. Higher gilt yields raise the cost of servicing debt, a risk amplified by political uncertainty surrounding the Labour leadership. Analysts at Pantheon Macroeconomics estimate that if current yields persist, debt‑interest expenses could be £15 bn higher than budgeted for 2026/27. The Treasury’s recent fiscal measures—VAT cuts on family tickets, free bus travel for under‑16s, and reduced import duties on basic foods—aim to ease household pressure but will need to be funded, potentially through tighter tax rules for oil and gas firms.

Looking Ahead Watch the OBR’s revised fiscal outlook in the autumn Budget and gilt‑yield movements ahead of the Bank of England’s next rate decision, as both will shape the trajectory of UK borrowing and debt‑service costs.
