Britain's public finances are on an "unsustainable and ever-rising path," risking a humiliating bailout reminiscent of 1976, according to warnings from the Office for Budget Responsibility (OBR) and prominent economists. The OBR's assessment, unusually stark for the fiscal watchdog, suggests the UK must identify an additional £120 billion per year through tax increases or spending cuts to prevent national debt from spiraling out of control.
Heavyweight figures in economics have echoed these concerns. Ken Rogoff, former chief economist at the International Monetary Fund (IMF), has stated there is a "more than 50:50 chance" of a major UK debt crisis before the end of the decade. Sir Charlie Bean, a retired deputy governor of the Bank of England, has also warned that a bailout is a "material risk."
To put the required £120 billion annual fiscal adjustment into perspective, it is equivalent to the entire state education budget and nearly double the defense spending. The OBR cautioned that attempting to close this gap solely through further taxation risks "ever-increasing economic distortions and costs," potentially curtailing growth, crushing investment, and discouraging enterprise.
The current government's fiscal policies, including increases in employers' National Insurance contributions and new employment rights laws, have reportedly impacted recruitment. Data from the Office for National Statistics indicated a rise in the unemployment rate to 5 percent in May, up from 3.6 percent in 2022. Youth unemployment has seen a particularly sharp increase, reaching 14.7 percent, the highest since late 2014.
Previous budgets have contributed to the fiscal pressure. The October 2024 budget reportedly raised taxation by £40 billion annually and increased borrowing by £30 billion to fund welfare programs. A subsequent budget in November last year allegedly added another £30 billion in taxes to cover the rising costs of welfare payments. The projected tax burden is now anticipated to reach 40 percent of GDP.
Spending on welfare has surged, with the country spending £334 billion last year, exceeding income tax revenue of £331 billion. The number of individuals on Universal Credit has surpassed 8 million, while the cost of long-term sickness payments has accelerated. This expansion in welfare, coupled with rising debt servicing costs, has ballooned government borrowing. Initial OBR predictions foresaw an additional £323 billion in borrowing over five years, but after just two years of the current government, this forecast has soared to £583 billion, an 80 percent increase.
Britain's borrowing costs are higher than other G7 nations, with interest rates on ten-year government bonds around 5 percent. With nearly a third of government debt linked to inflation, the debt service bill amounts to £301 million daily. In the past year, £129 billion was borrowed, with 80 percent allocated to debt interest payments. Over the four years since the COVID-19 lockdown, more than four-fifths of government borrowing has been used to cover debt interest.
Economists warn that the UK's public finances are increasingly vulnerable to shifts in market sentiment. A growing portion of government creditors are speculative buyers like hedge funds, who may divest holdings rapidly if sentiment turns, potentially triggering a sharp increase in borrowing costs and leading to a "death spiral" of further borrowing to meet obligations. Such a scenario could necessitate another appeal to the IMF for a bailout, leading to severe austerity measures, currency devaluation, and a significant cost-of-living crisis.
