GB: Public Sector Finances
| Actual | Previous | Revised | |
| Public Sector Net Borrowing | £18.0B | £1.1B | £2.8B |
| Ex-Public Sector Banks | £18.0B | £1.1B | £2.8B |
Highlights
The UK's public finances in August 2025 revealed mounting fiscal pressures. Borrowing reached £18.0 billion, the highest August figure in five years and £3.5 billion more than a year earlier. Over the financial year to date, borrowing stood at £83.8 billion, making it the second-highest AprilAugust total since records began in 1993, surpassed only during the extraordinary pandemic year of 2020.
Much of the strain is tied to the current budget deficit, which hit £13.6 billion in August and £62.0 billion across the year so far, £13.8 billion above last year's equivalent period. This suggests that the rising cost of day-to-day government operations continues to outpace revenue collection.
Debt levels also remain historically elevated. Net debt, excluding public sector banks, was 96.4 percent of GDP, edging higher than last year and echoing ratios last seen in the early 1960s. Meanwhile, net financial liabilities were 84.5 percent of GDP, lower than debt but still widening year-over-year.
The central government's net cash requirement was £11.1 billion, almost unchanged from August 2024. Overall, the figures show fiscal space tightening, with the government balancing high borrowing needs against the challenge of stabilising debt at near-record levels.
Definition
The public sector net borrowing requirement (PSNB) is the difference between the sector's receipts and expenditure and so provides a simple measure of government fiscal policy. In response to the global economic crisis in 2008/09 the UK government introduced a number of measures designed to show the underlying state of public sector finances by omitting temporary distortions caused by financial interventions. It bases its fiscal policy on these measures. To this end, the underlying gauge of government borrowing watched most closely by financial markets is the PSNB-X which takes overall net borrowing (PSNB) but excludes public sector banks.
Description
Changes in public sector finances can be used to determine the thrust of the government's fiscal policy. Generally speaking when the government has a rising deficit (or falling surplus) it is loosening its fiscal stance with a view to boosting economic activity. When its deficit is falling (or surplus rising), fiscal policy is being tightened in order to slow economic growth. However, sometimes changes in government financial positions can be due to factors outside of the government's control and do not signal an explicit shift in policy. This means that great care is needed in interpreting the data.
