The United Kingdom borrowed more than anticipated in April, as elevated inflation increased the cost of pensions and benefits, while concerns over the Iran conflict and political instability added to debt servicing costs.
Borrowing Figures Exceed Expectations
According to the Office for National Statistics (ONS), public sector net borrowing—the gap between government expenditure and revenue—stood at £24.3 billion in April 2026. This marks an increase of £4.9 billion compared to April 2025 and is £3.4 billion higher than the forecasts provided by City economists and the Office for Budget Responsibility.
The rise in borrowing costs on financial markets pushed the UK's debt interest payments to £10.3 billion in April, up £900 million from the same month last year, setting a new record for any April.
Grant Fitzner, chief economist at the ONS, commented: "Borrowing this month was substantially higher than in April last year. Although receipts increased compared with April 2025, this was more than offset by higher spending on benefits and other costs."
Market Jitters and Political Uncertainty
The figures come amid a sharp increase in the UK government's borrowing costs on financial markets in recent weeks. With Prime Minister Keir Starmer's hold on power appearing to weaken, UK government bonds, known as gilts, have faced significant selling pressure.
In the context of turbulent global markets, investors worry that his successor as prime minister might increase borrowing. Earlier this week, the International Monetary Fund urged Britain to "stay the course" on Chancellor Rachel Reeves's plan to reduce government borrowing, cautioning that the government lacks the capacity to significantly add to its already high debt levels.
Martin Beck, chief economist at the consultancy WPI Strategy, noted: "A future prime minister may rail against being 'in hock' to the bond markets, but that’s a difficult argument to sustain for a government on course to borrow well over £100 billion this year and dependent on investor willingness to fund its deficit."
Impact of Inflation on Benefits and Pensions
Inflation-linked increases in many benefits and the pensions triple lock also contributed to the borrowing rise in April. The ONS reported that net social benefits paid by central government increased by £2.7 billion to £29.5 billion for the month.
These figures follow Britain's stronger-than-expected economic performance at the start of 2026, before the outbreak of the Iran war. Highlighting the economy's resilience, the ONS revised down its borrowing estimate for the financial year ending in March 2026 by £3 billion to £129 billion. This was 15% lower than the borrowing figure a year earlier and £3.7 billion below the official forecasts made by the OBR.
Lucy Rigby, the Chief Secretary to the Treasury, stated: "Earlier this week the IMF agreed we had the right economic plan to reduce the deficit. We are cutting borrowing and debt—with our actions reducing government borrowing by over £20 billion last year—while driving growth through £120 billion of additional capital investment over the parliament."
