UK Government Borrowing Surges Past Expectations Ahead of Budget

The UK government's borrowing has exceeded expectations in August, increasing concerns about Prime Minister Andy Burnham's fiscal rules. Public sector net borrowing reached £18.3 billion ($24.5 billion), surpassing a Reuters poll of economists' forecast of £15.5 billion. This surplus pushes the deficit for the financial year to date above official forecasts and sets a challenging backdrop for Finance Minister John Healey's first budget next month.

The Office for National Statistics (ONS) revised up borrowing for each of the previous four months, with the April-August cumulative deficit standing at £77.3 billion. This is £8.1 billion higher than the Office for Budget Responsibility (OBR) had expected at this point in the year. The rise in gilt yields since the OBR's Spring forecast has halved Healey's fiscal wiggle room, leaving just over £10 billion of headroom against the government's primary fiscal rules.

Healey faces pressure to show how he can meet his fiscal rules without raising main taxes, having promised to control spending. The forecasts that underpin the budget will incorporate higher government borrowing costs and market expectations for rising Bank of England interest rates, cutting Healey's room to help families and businesses in the budget.
