South Korean banks' lending rates edged down in April amid a slight decline in deposit rates, central bank data showed Friday.

The average interest rate charged on new bank loans came to 2.74 percent in April, down 0.03 percentage point from the previous month, according to preliminary data from the Bank of Korea (BOK).

The BOK cut the key interest rate to a record low of 0.5 percent in May last year after delivering an emergency rate cut of half a percentage point in March to cushion the impact of the new coronavirus outbreak.

This week, the central bank kept the base rate steady, while upgrading this year's growth outlook to 4 percent.

The average rate for bank deposits, meanwhile, came to 0.84 percent in April, down 0.02 percentage point from a month earlier, the BOK said.

South Korean lenders' loan-deposit spread, a gauge of banks' profitability from lending, stood at 2.12 percent in April. (Yonhap)
