The U.K. government borrowed £23.3 billion ($30.77 billion) in May, marking a second consecutive monthly increase and suggesting significant difficulty in achieving planned budget deficit reductions.
This figure, reported by the Office for National Statistics on Friday, represents a £5.4 billion increase from May 2025 and is the second-highest May borrowing on record, surpassed only by the Covid-19 pandemic-affected 2020. It also overshot the Office for Budget Responsibility's (OBR) projections by £5.6 billion.
The surge in borrowing is primarily attributed to a £4.1 billion rise in interest payments on government debt, exacerbated by the U.K.'s higher proportion of inflation-linked bonds and price increases stemming from the Middle East conflict. Concurrently, tax revenue growth has slowed, and the U.K. economy contracted in April, reflecting diminished household and business confidence alongside elevated energy costs.
The Organization for Economic Cooperation and Development (OECD) forecasts U.K. economic growth at just 0.9% for this year, a notable deceleration from 1.4% in 2025 and below the OBR's 1.1% forecast, which will further depress tax revenues. This fiscal strain presents a considerable challenge for the government, particularly as Prime Minister Keir Starmer faces a leadership challenge from Andy Burnham, who has affirmed support for existing fiscal rules aiming to balance day-to-day spending with tax revenues by the decade's end.
