Middle East Conflict Renders Rachel Reeves' Spring Statement Outdated
UK Chancellor Rachel Reeves would not have chosen to deliver her Spring Statement against the backdrop of a fresh threat to the global economy. While she announced having the "right economic plan for the country" in a "yet more uncertain world," the escalating conflict in the Middle East will undoubtedly complicate Britain's economic prospects. The latest economic forecast by the independent Office for Budget Responsibility, to which she was responding, may already be obsolete.
Immediate Economic Disruption
It was too late for the OBR calculations to include potential shocks in global supply chains or spikes in energy prices resulting from US-Israeli strikes on Iran. At a press conference following Reeves' statement, an OBR representative warned that the conflict could have "a very significant impact." They added that even before this crisis unfolded, the UK faced an unusually high degree of economic uncertainty.
Otherwise, the OBR report—little changed from autumn—paints a mixed picture for the UK economy. Weaker economic and job growth are somewhat balanced by prospects of lower inflation and reduced interest rates. The government's future "headroom" for extra spending is only slightly better than previously thought, with government debt projected to remain at 95% of GDP by 2031.
Energy Market Volatility
The OBR noted that this high debt level relative to other countries makes the UK more vulnerable to external risks. Yet Reeves told MPs bullishly: "We beat the forecasts last year [...] we will beat them again," asserting that stronger government finances would allow Britain to weather the storm and maintain current spending plans.
However, the war could significantly affect those spending plans and government hopes of tackling the high cost of living. Oil and gas prices are already soaring, while stock markets decline. The OBR itself accepts that "significant risks, including from conflict in the Middle East," can dramatically alter its projections.
For example, gas prices have spiked after major Middle East supplier Qatar closed its main refinery following Iranian attacks. The effective closure of the Strait of Hormuz threatens the huge flow of oil to major Asian economies including China, Japan, Korea, and Taiwan.
Broader Economic Consequences
Although the UK government has capped household gas prices, a long-term wholesale gas price increase would boost inflation and reduce chances of further interest rate cuts by the Bank of England. While Britain gets relatively little gas directly from the Middle East, gas and oil prices are set internationally. Europe's greater dependence on gas from that region means supply disruption could threaten both higher inflation and lower growth in the UK's largest export market.
This situation could pose an existential threat to high-performing Asian export economies that drive global growth. A worldwide slowdown would have serious consequences for the UK economy, which remains highly dependent on foreign trade. US President Donald Trump's dissatisfaction with Prime Minister Keir Starmer's conditional support for his war may threaten restoration of Britain's favourable tariff deal.
Domestic Fiscal Challenges
A weaker UK economy—already growing at just over 1% annually—would have major consequences for government spending, tax receipts, and fiscal headroom. This could mean both lower tax revenues and increased borrowing, with government debt financing costs rising and reversing recent falls.
These developments may make it difficult for the government to contemplate electorally beneficial tax cuts ahead of the 2029 general election. It might even have to extend the freeze on tax thresholds further, squeezing workers' pay packets.
These negative developments come as the government faces major additional spending pressures it has tried to delay in hope of a stronger balance sheet later. These include costly reforms to increase spending on students with special educational needs and disabilities, plus plans to reduce student debt. Other long-term challenges include providing social care for an ageing population, meeting ambitious housing targets currently behind schedule, and supporting cash-strapped local government.
Defence Spending Implications
Rising geopolitical tensions could force the government to accelerate plans boosting UK defence spending from 2.5% to 3.5% of GDP, at an estimated cost of £40 billion. This could well necessitate tax rises or further cuts in other departments.
A short and decisive war might lessen all these pressures. However, uncertainty itself can inhibit investment and threaten Britain's ability to tackle its long-term productivity problem—the key to raising living standards. The Middle East conflict has thus created immediate challenges for Chancellor Reeves' economic strategy, potentially rendering her Spring Statement outdated almost as soon as it was delivered.
