UK Deficit Surge Pressures Reeves Over Potential Tax Rises and Spending Cuts

The British government has been confronted with a swelling fiscal deficit, prompting renewed debate over the direction of tax and spending policy under Chancellor Rachel Reeves. According to the latest data, government borrowing in the six months to September reached £99.8 billion—£7.2 billion higher than projected by the Office for Budget Responsibility. This figure marks the highest half-year borrowing since the extraordinary conditions of 2020, and only the second time such levels have been recorded since monthly figures began in the early nineties.

Rachel Reeves has acknowledged that Brexit, in addition to previous austerity measures and reductions in capital spending, has had a larger-than-expected impact on the economy. Addressing business leaders in Birmingham, the Chancellor emphasised the government’s commitment to rebuilding relations with the European Union to ease the strain on public finances. Reeves also hinted that the Office for Budget Responsibility may lower economic forecasts in the forthcoming budget, while reiterating her determination to accelerate economic growth.

The cost of servicing public debt has become an urgent concern, with annual debt interest payments exceeding £100 billion. Sir Robert Chote, former chief of the OBR, has cautioned that politically difficult spending cuts may be needed to avoid a fiscal crisis. A recent report from the Policy Exchange think tank, which Chote endorsed, recommends a range of highly sensitive measures, including freezing the state pension, raising the retirement age to 70, freezing working age benefits, tightening disability benefit eligibility, and replacing the NHS with a Dutch-style insurance model.

These proposals—if considered—would represent a significant shift in the UK’s approach to the welfare state and public services, underscoring the seriousness of the fiscal challenge. The debt to GDP ratio now stands at 95.3 per cent, the highest since the early 1960s, raising questions about the government’s ability to finance its commitments without new sources of revenue.

Labour’s leadership has become more vocal about what it sees as the lingering economic impact of Brexit, with Reeves seeking to counter criticism over potential tax increases by highlighting the need to reduce the burden of additional costs on UK businesses and workers. National insurance contributions collected from companies have risen, yet increases in public spending—particularly on benefits and debt interest—continue to overshadow these gains.

Amid forecasts that revenue gains alone will not bridge the fiscal gap, pressure is mounting on Reeves to consider increases to one or more of income tax, VAT, or national insurance. Such a move would break key manifesto pledges but is looking increasingly probable given the scale of the deficit. The months ahead will test the government’s resolve and shape the future of fiscal policy in the United Kingdom.
