GB: Public Sector Finances
| Actual | Previous | Revised | |
| Public Sector Net Borrowing | £12.6B | £14.3B | £12.8B |
| Ex-Public Sector Banks | £12.6B | £14.3B | £12.8B |
Highlights
The latest UK fiscal data showed that monthly borrowing in March 2026 fell to £12.6 billion, reinforcing a broader annual improvement as total borrowing declined to £132.0 billion, modestly outperforming expectations from the Office for Budget Responsibility (OBR). At 4.3 percent of GDP, the deficit is narrowing towards pre-pandemic norms, signalling tighter fiscal control without abrupt retrenchment.
The most notable shift lies in the current budget deficit, which dropped sharply by one-third to 1.7 percent of GDP. This suggests improved discipline in day-to-day spending, often a more politically and economically sensitive component of fiscal policy. The reduction implies that consolidation is being driven less by capital cuts and more by operational efficiency or revenue gains.
However, structural pressures remain evident. Public sector net debt has edged up to 93.8 percent of GDP, maintaining levels not seen since the early 1960s, while broader liabilities have risen further. This divergencefalling deficits alongside elevated debtreflects the lagged effects of past borrowing and ongoing financing needs.
In summary, the fiscal stance appears cautiously stabilizing as short-term metrics are improving, but long-term sustainability remains contingent on sustained growth and continued fiscal discipline.
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.
