Britain’s Finances Under Fire as Global Turmoil Hits Home
As escalating tensions in the Persian Gulf saw key energy infrastructure targeted, the ripple effects of conflict have reached far beyond the immediate region, placing significant strain on the United Kingdom’s public finances. While global energy prices surged due to tit-for-tat strikes between Iran and Israel, the economic consequences for Britain have been particularly stark, exposing a vulnerability in its fiscal planning.
Chancellor Rachel Reeves, while on a trade mission in Madrid, found her government’s financial framework facing considerable pressure. Unlike many other major economies, Britain’s public finances have been left exposed to external shocks, such as the current surge in oil and gas prices driven by the Middle East conflict.
With the conflict now entering its fourth week, the clamour for further government intervention to cushion households from rising fuel bills is intensifying. Projections from Cornwall Insight, a consultancy, indicate that typical dual-fuel household energy bills could increase by £332 to £1,973 annually when the energy price cap is next reviewed in July.
A prolonged conflict in the Middle East carries the potential to trigger broader inflation, impacting everything from food prices to airfares. This, in turn, could compel the Bank of England to consider further interest rate hikes. Millions of borrowers and mortgage holders could face as many as four base-rate increases this year, pushing the benchmark borrowing cost back towards the 4.75 per cent mark, not far from the 5.25 per cent peak seen in 2023 when the Bank of England was battling double-digit inflation.
Traders have already begun to react to this precarious economic landscape. On Friday, a sell-off of gilts – government debt securities – intensified following the release of disappointing figures revealing a significant ballooning of government borrowing and debt interest costs in February.
The yield, or interest rate, on ten-year gilts climbed above 5 per cent for the first time since the 2008 financial crisis. Compounding these concerns, the national debt, measured as a proportion of the economy’s output (Gross Domestic Product), has doubled over the past 18 years, significantly increasing the overall debt burden.
This bond market sell-off is being widely interpreted as a critical verdict on the current state of the UK economy. As the guardian of the public purse, the Chancellor faces a challenging environment, ill-equipped to weather the gathering economic storm, let alone provide additional financial support.
Despite imposing substantial tax increases on businesses and individuals, the Chancellor’s decision to increase borrowing to cover rising welfare costs has left her with limited flexibility to meet her own fiscal objectives.
The Tightening Grip of Fiscal Rules
A key commitment is to balance day-to-day public service spending with tax receipts by the end of the decade, a crucial step to maintain investor confidence. However, after a recent adjustment to increase the fiscal headroom, or safety buffer, in the last Budget, the Chancellor has only £24 billion to work with – a historically low figure.
This amount is merely half the cost of the energy price guarantee that was implemented by the previous government following Russia’s invasion of Ukraine in 2022, which caused energy prices to skyrocket.
Shadow Chancellor Sir Mel Stride has voiced concerns, stating, “The fragility of our economy is about to be exposed.” Richard Hughes, a former head of the Office for Budget Responsibility, has also commented that the Chancellor’s fiscal rules are “among the loosest” since their introduction in 2010, designed to curb debt-fuelled spending, and have “done little” to enhance fiscal resilience. He suggested that a buffer exceeding £50 billion would provide the Treasury with more scope to respond to economic shocks.
The escalating cost of servicing the nation’s substantial debt is already eroding this slender financial buffer. Senior economist Dennis Tatarkov from KPMG has warned that if higher borrowing costs persist into the autumn, the headroom could shrink by an additional £10 billion.
Navigating Policy Dilemmas
The Chancellor is also facing pressure to reverse a planned 5 pence per litre increase in fuel duty scheduled for September. Such a move would likely be popular with motorists already grappling with elevated fuel prices.
However, extending the fuel duty freeze would push the total taxpayer support for drivers to an estimated £150 billion since its inception in 2011, according to Gideon Salutin of the Social Market Foundation think-tank. He further noted that maintaining the frozen fuel duty level would result in nearly £17 billion in additional losses for the government over the next four years.
Such a significant impact on public finances would undermine the Chancellor’s fiscal objectives and further erode investor confidence in Britain’s ability to manage its economy.
This is all before considering the planned increase in defence spending.
Sterling and the Shadow of Uncertainty
One significant “known unknown” is the performance of the British pound. Thus far, sterling has demonstrated relative resilience, holding steady at around $1.34 against a resurgent US dollar, which has strengthened globally as investors seek safe havens amidst the Middle East turmoil.
However, traders have been steadily increasing their bets against the pound, reaching levels not seen since just before the tumultuous Liz Truss mini-Budget in 2022. That period saw a sharp decline in sterling’s value, bringing it close to parity with the US dollar.
If these market expectations prove correct and the pound weakens again, it would lead to higher import costs. This would fuel inflation and likely result in even steeper borrowing costs for the government, businesses, and households as interest rates are raised to combat these increased import expenses.
Despite these concerns, some experts believe a repeat of the 2022 scenario, where UK assets like sterling and gilts collapsed simultaneously, is improbable.
Andrew Wishart, an economist at investment bank Berenberg, commented, “The Persian Gulf and Strait of Hormuz are critical for global energy supply, but not freight or manufactured goods.” He added that measures of container shipping and bulk shipping costs remain stable.
These costs had previously surged after COVID-19 restrictions were eased. Since then, the number of job vacancies has fallen by half, while unemployment has risen from 1.3 million to 1.9 million, reducing the risk of a renewed wage-price spiral, according to Wishart.
Nonetheless, he has revised his UK growth forecast for the current year downwards from 0.9 per cent to 0.6 per cent, citing the impact of rising energy prices. This projection is based on the Bank of England maintaining interest rates at 3.75 per cent. However, he cautioned that if interest rates were to rise, as investors anticipate, a recession could become a serious possibility. In such a scenario, without spending cuts or further tax increases, the government would likely miss its fiscal targets outlined in the autumn Budget.
The Treasury has stated, “We have the right economic plan and that includes this Government’s commitment to its non-negotiable fiscal rules being ironclad.”
While Chancellor Reeves may face pressure from her own party to once again bend the fiscal rules to accommodate further bailouts, financial markets are unlikely to be swayed. Investors are already demanding a higher return for lending to Britain than to any other advanced economy, and at levels significantly exceeding those seen during the Truss administration. This suggests that a premium for perceived economic policy missteps is making a return.
