The UK government's coffers have been stretched to breaking point, as borrowing surged to an eye-watering £23.3 billion in May, catapulting beyond even the most pessimistic forecasts. This colossal sum represents a 30% (£5.4 billion) increase on last year's equivalent figure and shatters the Office for Budget Responsibility's (OBR) projection of £17.7 billion by a staggering £5.6 billion.
This unprecedented borrowing spree has propelled the current financial year's government borrowing to £46.3 billion, surpassing OBR forecasts by a substantial £7.7 billion. The Office for National Statistics (ONS) highlighted that the first two months of this financial year have seen nearly £9 billion more borrowed than in 2025, with increased expenditure across debt interest, public services, investment, and benefits outweighing higher tax receipts.
The broad implications are stark: the UK's national debt now stands at a record-breaking 95.1% of Gross Domestic Product (GDP), its highest level since the early 1960s. This raises long-term concerns about economic stability and underscores the substantial challenges facing policymakers in maintaining fiscal sustainability. The ongoing high levels of borrowing will exert significant pressure on future government spending decisions and policy.
Economists have expressed deep unease regarding the public finances, with Martin Beck, chief economist at WPI Strategy, describing the underlying picture as “uncomfortable”. He noted that the deficit remains substantial, debt interest continues to consume a large portion of government revenue, while the overall tax burden is set to reach post-war highs. This limits the scope for easy solutions through increased borrowing or taxation.
Joe Nellis, an emeritus professor and economic adviser at MHA, echoed these sentiments, stating that the UK's public finances are “not in comfortable territory”. He underscored the ongoing difficulty of balancing essential public sector spending requirements with the government's commitment to maintaining a sustainable financial path. These latest figures suggest difficult choices lie ahead for the Treasury and the government for the remainder of the financial year.
