The International Monetary Fund has upgraded the UK economic growth forecast for 2026 to 1.3% while warning that rising energy prices and interest rates will slow expansion down to 1.2% by 2027. John Healey faces mounting fiscal pressure ahead of the upcoming autumn budget.
IMF Growth Upgrades and 2027 Energy Pressures
The UK economy is forecast to grow by more than previously expected this year before higher energy prices and interest rates hit growth in 2027. According to the International Monetary Fund, the economy will expand by 1.3% in 2026—an increase from the 1% prediction issued in July. The revision reverses earlier downgrades prompted by the start of the US-Iran conflict, positioning the UK as having the second-fastest growing economy in the G7 along with Germany.
That momentum faces a clear ceiling. Growth is estimated to slow in 2027 to 1.2% as higher energy prices and long-term interest rates weigh heavily on household spending and business investment. Global economies have demonstrated a “remarkable capacity to absorb shocks” extending from the current Middle East conflict back through the COVID-19 pandemic and Russia’s invasion of Ukraine, though the IMF cautioned that fallout from ongoing Middle East hostilities remains highly uncertain

John Healey Confronts £35bn Fiscal Gap
John Healey is finalizing tax and spending plans for the upcoming October 28 budget amidst surging government borrowing costs that demand credibility with financial markets. Economists suggest Healey faces having to find £35bn to avoid cuts to public spending while meeting defence promises.
Healey acknowledged that conflicts in the Middle East and Europe are hitting people in the UK and around the world
but insisted that Britain’s economy is showing strong international resilience
. The government aims to provide some breathing space
for households during the winter months, even as public finance watchdogs urge fiscal repairs.
Despite the immediate fiscal squeeze, the IMF projected that the UK would have a sharp fall in borrowing and the lowest annual rate of borrowing of all G7 countries over the next five years. The UK is estimated to have the lowest annual deficit by 2031.
Political Crossfire Over Inflation and Tax Pressures
Andrew Griffith, Conservative shadow chancellor, warned that if Healey reaches for more tax rises
in his Budget, he is choosing slower growth and working people will pay for it

Meanwhile, households continue to face inflationary headwinds. The IMF projects inflation to average 3.3% this year and remain above the Bank of England’s 2% target in 2027 at 2.8%. The Bank of England itself has predicted inflation could rise above 4% at the beginning of next year – making it more likely that interest rates will rise.
