Britain’s total public debt has ticked over the symbolic £3 trillion mark, roughly $4 trillion, for the first time, Reuters reported, citing official data. The rapid rise in sovereign liabilities has been driven chiefly by persistent increases in government spending. Net government borrowing reached £24.52 billion in September, well above most analysts’ forecasts. The cumulative budget shortfall swelled to £97.8 billion, about £6 billion higher than the government had planned, though roughly £4.4 billion below the level recorded a year earlier.
The debt shock is unfolding alongside intensifying inflationary pressures. The Office for National Statistics reported that consumer inflation accelerated to 3.5% year‑on‑year in September, marking the sharpest monthly uptick since October 2025 and the third consecutive monthly rise. The Bank of England left its policy rate unchanged at 3.75% in September but warned that upside risks to prices persist.
Officials point to the protracted Middle East conflict as the main catalyst for the current instability, which has driven a sharp increase in prices for crude and refined products. Higher energy costs are feeding directly into producers’ bills and household expenditures in the UK. After inflation climbed to 3.1% in August and then jumped in September, the BoE warned that the trend of rising prices for goods and services is likely to continue into the coming quarters. That dynamic will make it harder for the Labour government to contain the deficit and stabilize the record stock of public debt.
