Britain is set to suffer the most severe economic shock among advanced economies this year, according to a stark warning from the International Monetary Fund, in a development that delivers a significant political and economic blow to the government.
In its latest assessment, the IMF downgraded the UK’s growth outlook for both this year and next, while also forecasting the highest inflation rate in the G7 and one of the weakest improvements in living standards globally.
The Fund further cautioned that escalating tensions in the Middle East could push the global economy towards recession.
The findings intensify pressure on Chancellor Rachel Reeves and Prime Minister Keir Starmer, whose handling of the economy is facing mounting criticism. The IMF said Britain’s slowdown would be sharper than that of its peers “as the impact of higher energy prices linger”, exposing what critics argue are deep vulnerabilities under the government’s approach.
Energy Dependence Exposed
A central weakness highlighted by the IMF is the UK’s reliance on imported energy, particularly gas. With most households dependent on gas for heating, and with limited storage compared with European counterparts, the country remains highly exposed to global price shocks.
Pierre-Olivier Gourinchas, the IMF’s chief economist, said: “The UK is highly reliant on gas for its energy mix.”
He added: “A lot of this gas is produced domestically, but there is still a part that is imported. And the part that is imported is at market prices – it’s much more expensive.
“And that sets the price for energy in the UK, in an environment in which gas reserves are relatively low when you compare them to other European countries.”
Rising energy costs are expected to weigh heavily on households for at least two years. Analysts warn that gas and electricity bills could rise by nearly 20 per cent this summer, pushing the average annual bill close to £2,000.
The situation has intensified criticism of Labour’s energy policies, particularly decisions linked to Energy Secretary Ed Miliband. There are growing calls to accelerate domestic energy production, including development of North Sea resources such as the Jackdaw gas field, which could supply up to 6 per cent of UK demand.
Weak Growth and Rising Inflation
The IMF now expects the UK economy to grow by just 0.8 per cent this year, down from 1.3 per cent forecast three months ago. Growth projections for 2027 have also been revised down to 1.3 per cent.
By contrast, the United States is expected to grow by 2.3 per cent this year.
Inflation in the UK is forecast to peak near 4 per cent, driven by higher energy and food costs. The IMF warned that fertiliser shortages and supply disruptions could lead to “substantial” food price increases.
This combination of weak growth and rising inflation presents a difficult challenge for policymakers. Megan Greene of the Bank of England said the situation “puts central bankers in the most awkward position possible”.
“We have had inflation above target for the best part of five years in the UK, so to my mind the inflationary piece of this is really important,” she said.
The Bank is now expected to hold interest rates at 3.75 per cent for longer than previously anticipated, with the possibility of further increases.
Living Standards and Jobs Under Pressure
Living standards are forecast to stagnate, with output per person expected to rise by just 0.3 per cent, one of the weakest performances among major economies. The Resolution Foundation estimates that higher prices will leave the average household £480 worse off this year.
Unemployment is projected to rise to 5.6 per cent, from 5.2 per cent, potentially pushing an additional 150,000 people out of work.
Political Fallout
The downgrade has prompted sharp criticism from opposition figures. Conservative leader Kemi Badenoch said: “When Conservatives left office, we had the highest growth in the G7… now we’ve been given the biggest downgrade.
Reeves and Starmer have driven the economy into the gutter and now the country is paying the price.”
Shadow chancellor Mel Stride described the IMF’s assessment as “a clear verdict on Rachel Reeves’s choices”, adding: “Her ‘plan’ to keep costs down has left us with the highest inflation in the G7, with businesses closing and the cost of living skyrocketing.
“The Conservatives urge international partners to see Rachel Reeves as a cautionary tale of what happens when a politician has no clue what they’re doing and chooses to hammer business relentlessly.”
Despite the criticism, Reeves defended the government’s approach, stating: “We entered this conflict in a stronger position because of the choices this Government took to build economic stability, but there is more to do.”
Global Risks Mount
Beyond the UK, the IMF warned that the global economy faces “tremendous” risks. A prolonged disruption in the Middle East, particularly involving the Strait of Hormuz, could trigger what it described as the “largest energy crisis in modern times”.
“A longer shutdown of the Strait of Hormuz and further damage to drilling and refining facilities would disrupt the global economy more deeply and for longer,” Mr Gourinchas said.
Under a severe scenario, oil prices could exceed $100 a barrel, pushing global inflation above 6 per cent and bringing the world economy close to recession.
Even in a more favourable outcome, global growth in 2026 is expected to slow to 3.1 per cent.
The IMF cautioned governments against broad subsidies to offset rising energy costs, arguing such measures are often inefficient. Instead, it recommended “narrowly targeted and temporary” support, a position that may limit the government’s options as pressure grows to support households and businesses.
