The Confederation of British Industry's (CBI) monthly retail sales balance, a gauge of sales versus a year ago, fell in January to -50 from -32 in December, the lowest reading since January 2021 when Britain was in a COVID-19 lockdown.

The survey pointed to an equally dismal February.

During the survey's 40-year history, the retail sales balance has fallen as low as -50 only during the COVID-19 pandemic and the 2008-09 global financial crisis.

While Thursday's report is the latest sign that retailers are still feeling the strain from the rise in prices and interest rates over the last two years, other surveys have painted a healthier picture of the wider business economy.

"Looking ahead, demand conditions in the (retail) sector will remain challenging as higher interest rates continue to feed through to mortgage payments and household incomes," said Martin Sartorius, CBI principal economist.

The survey covered 52 retailers between Dec. 21 and Jan. 15.

Official data published last week showed British retailers suffered the biggest drop in sales for almost three years during December, raising the risk that the economy slipped into recession late last year.
