UK May Borrowing Hits £23.3bn, Exceeding Forecasts and Pushing Debt to 95% of GDP

AI Summary
Net borrowing in May 2026 rose to £23.3bn, £5.4bn above the previous year and £5.6bn beyond the OBR’s forecast. The surge lifts total fiscal year borrowing to £46.3bn and pushes national debt to 95.1% of GDP, the highest level since the early 1960s.

UK public finances showed a sharp jump in borrowing for May 2026, with net borrowing reaching £23.3bn, well above the Office for Budget Responsibility’s forecast and pushing national debt to its highest share of GDP since the early 1960s.

May Borrowing Surpasses OBR Forecasts

The Treasury reported that May’s borrowing was £5.4bn higher than a year earlier and £5.6bn above the Office for Budget Responsibility (OBR) projection of £17.7bn. This marks the largest May‑month borrowing since the 2020 Covid‑19 lockdown.

Fiscal Numbers Reveal Record Debt Levels

  • Fiscal year borrowing (April‑June) now stands at £46.3bn, £7.7bn over the OBR’s forecast.
  • National debt has risen to 95.1% of GDP, a ratio not seen since the early 1960s.
  • Debt‑interest payments jumped by £4.1bn to £11.7bn due to higher RPI‑linked inflation.
  • Central government spending on goods and services increased by £2.2bn to £39.6bn.
  • Net social benefits rose by £1.2bn to £28.4bn, driven by inflation‑linked and earnings‑linked pension adjustments.

Implications for UK Fiscal Policy and Markets

The widening gap between actual borrowing and the OBR’s outlook raises concerns that the government could breach the fiscal rules set by Chancellor Rachel Reeves. Analysts warn that higher debt servicing costs and limited fiscal space may constrain future policy choices, increase pressure on gilt yields, and heighten market scrutiny ahead of the Autumn Budget.

Outlook: What Next for Government Borrowing?

Unless there is a significant shift in spending discipline or a boost in tax receipts, borrowing is likely to remain above forecast for the remainder of the financial year. The upcoming budget will be pivotal in determining whether the Treasury can rein in the deficit, adjust fiscal rules, or resort to additional borrowing to meet public‑service demands.
