UK Government Borrowing Exceeds Forecasts, Posing Challenges for Healey's Budget

Government Borrowing and Fiscal Outlook

By Andy Bruce

MANCHESTER, England, Sept 22 (Reuters) - Britain's government borrowed more than expected in August, pushing the deficit for the financial year to date further above official forecasts and adding to a tough backdrop for finance minister John Healey's first budget next month.

Public sector net borrowing stood at £18.3 billion ($24.5 billion) in August, the Office for National Statistics (ONS) said on Tuesday, above all forecasts in a Reuters poll of economists which had pointed to a £15.5 billion deficit.

Market Reaction and Investor Sentiment

With investors worried about the possibility of further borrowing by the new government, gilt futures sank 20 ticks after the data before recovering, and yields in the cash market rose modestly as it opened.

Upcoming Budget and Fiscal Policy Challenges

Healey presents his budget on October 28. He is under pressure to show how he can meet his fiscal rules without raising the main taxes, having promised to control spending that Tuesday's data showed is being pushed higher by inflation.

Impact of Global Events on Borrowing Costs

British government bond yields have soared since the onset of the Iran war pushed up global oil and gas prices, reflecting the risk of a damaging rise in inflation caused by Britain's reliance on imported energy.

Budget Forecasts and Constraints

The forecasts that underpin the budget will incorporate the higher government borrowing costs as well as market expectations for rising Bank of England interest rates, cutting Healey's room to help families and businesses in the budget.

Taxation Options and Political Promises

Prime Minister Andy Burnham has ruled out raising the rates of income tax, value-added tax, corporation tax or social security contributions, so Healey may have to lean on capital gains, property and wealth taxes to raise revenue.

Fiscal Headroom and Borrowing Revisions

FISCAL HEADROOM HAS FALLEN MARKEDLY

"Medium-term borrowing prospects look far more challenging than in March," said Matt Swannell, chief economic adviser to the ITEM Club, a consultancy.

The ONS revised up borrowing for each of the previous four months of the 2026/27 financial year, with the April-August cumulative deficit this year standing at £77.3 billion.

Although £2.2 billion less than at the same point in 2025/26, it was £8.1 billion higher than the Office for Budget Responsibility (OBR) had expected at this point in the year.

Borrowing for the previous 2025/26 year was revised up by £4.5 billion to £134.3 billion.

Government Response and Fiscal Rules

In response to the data, deputy finance minister Emma Reynolds reiterated that the government was committed to meeting the fiscal rules with a "buffer against uncertainty".

That buffer stood at more than £24 billion in March.

"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," Swannell said.

Robert Wood, chief UK economist at Pantheon Macroeconomics, said: "The government will also face significantly higher spending pressures if it tries to meet its well-flagged priorities of boosting investment in housing, reforming social care, and increasing defence spending."

Inflation and Government Spending

INFLATION RATCHETS UP GOVERNMENT SPENDING

An ONS statistician said that while tax receipts had looked strong, this had been offset by rising government spending on goods and services and welfare benefits linked to inflation.

The current budget deficit — or the difference between day-to-day spending and tax revenue, which the government must balance in 2029/30 — stood at £51.9 billion in the year to date.

Again, that was higher than the OBR's forecast for £47.1 billion at this point in the year.
