UK inflation could soar above 22% next year if energy prices continue their upward spiral, US investment bank Goldman Sachs has warned.

Iran PressEurope: Highlighting the pressure on households and businesses, the US investment bank said inflation could peak at 22.4% next year if wholesale gas and electricity prices continue to spiral over the winter.

In a scenario where prices “remain elevated at current levels”, economists at the bank said the Ofgem energy price cap for household bills could rise by more than 80% in January. This would “imply headline inflation peaking at 22.4%”.

Inflation rose above 10% for the first time since the early 1980s in July, fuelled by surging wholesale energy prices and the rising cost of basic essentials. Inflation hit a post-war record of 24.5% in August 1975.

The forecasts for inflation hitting levels unseen since the oil shock and industrial strife of the 1970s come as pressure mounts on Liz Truss, the Conservative leadership frontrunner, to clarify her plans for supporting households and businesses.

Amid concerns over the impact of rising gas and electricity bills, charities have warned many families could be plunged into destitution this winter.

Wholesale gas prices in the UK have climbed by 145% since the start of July amid fears of shortages this winter as Russia throttles supplies to Europe. Goldman said it did not expect the recent leap in European gas prices to persist, meaning inflation was likelier to peak at close to 15% early next year.

However, the bank’s analysts said they viewed persistently high gas prices as an “upside risk to our forecast,” suggesting there was potential for a significantly higher inflation rate than anticipated.

Gas prices have fallen back in recent days after Germany’s economy minister said its storage facilities had reached 85% of their capacity, ahead of expectations. The EU is also preparing to make “emergency interventions” which could help bring down current soaring prices.

The Goldman forecast is the latest eye-watering estimate for UK inflation, surpassing predictions made by the US bank Citi for an 18.6% peak next year. The Bank of England has forecast a peak above 13%.
