The UK economy is expected to grow faster in 2026 than the International Monetary Fund predicted in July. According to the BBC and the Guardian, the IMF’s latest forecast puts growth at 1.3%, up from 1%. But the improved outlook for this year comes alongside a downgrade for 2027 and a warning that higher energy costs and long-term interest rates will weigh on household spending and business investment.
The new estimates appear in the World Economic Outlook, the IMF’s assessment of prospects for the global economy. The Guardian reports that it was published on 13 October in Bangkok. The Fund raised its forecast for UK gross domestic product (GDP) growth in 2026 by 0.3 percentage points. For 2027, it now expects growth of 1.2%, down from its previous forecast of 1.3%.
A stronger forecast does not end the pressure on household budgets
An upgrade to the GDP forecast does not mean every household’s finances will improve. In the IMF’s assessment, energy costs and the cost of long-term borrowing remain a burden on the British economy, constraining spending and investment. All the growth figures are forecasts, rather than final economic results.
The BBC also reports that the Fund expects average UK inflation to reach 3.3% in 2026 and 2.8% in 2027. That would mean prices rising more slowly, but inflation would remain above the 2% target set by the Bank of England, the UK’s central bank. For people living in Britain, the distinction matters: lower inflation means slower price increases, not a return to earlier price levels.
Energy remains a major risk
The outlook for the global economy has also improved slightly. According to the Guardian, the IMF raised its global growth forecast for 2026 from 3% to 3.1%, while leaving its estimate for 2027 unchanged at 3.4%. The Fund judges that the world has weathered the effects of the conflict in the Middle East better than feared so far. Rerouted oil supplies and the use of strategic reserves have helped limit the impact of disruption on prices.
That resilience has limits, however. According to the report cited by the Guardian, dwindling energy stocks, high debt and budget deficits are restricting the scope to protect consumers from further price spikes. A prolonged stalemate or further escalation of the conflict could push up energy and food prices. Disruption to energy infrastructure, cyberattacks and extreme weather could intensify those effects. These are risks identified by the Fund, not events it considers inevitable.
The Guardian reports that the IMF forecasts global inflation of 4.7% in 2026 and 4.1% in 2027, with the estimate for next year raised from 4%. The Fund advises central banks not to overreact to short-lived inflation spikes, while remaining ready to act quickly if price pressures become persistent. For the UK, the latest forecast therefore offers moderately good news for 2026, without removing the risks to growth and household budgets in the following year.
