DATA & FIGURES
The £23.3bn borrowing figure for May is a significant increase from the expected £18.5bn, with debt interest costs higher than expected as financial markets responded to the Middle East conflict. Tom Davies, a senior statistician at the ONS, noted that borrowing in the first two months of the financial year was nearly £9bn higher than in the same period of 2025.
THE SCENARIO
The UK's higher-than-expected borrowing is largely attributed to the economic fallout of the Iran war, which has led to increased spending on debt interest, public services, and benefits. The conflict has also resulted in higher-than-expected inflation, which has boosted interest payments on inflation-linked government bonds.
DIRECT QUOTE
"The danger for Labour is that political uncertainty starts to carry a fiscal price. If investors begin to price in larger deficits or stickier inflation, gilt yields could move higher again, feeding directly into mortgage rates and debt interest costs." — Martin Beck, Chief Economist at WPI Strategy
BBN INSIGHT
