Outstanding overdraft-account balances at South Korean banks reached ₩69.7283 trillion at the end of July, up ₩6.0874 trillion, or 9.6%, from the end of last year. Account numbers increased only 0.5% to 4,893,636, lifting the average balance per account 9.0% to approximately ₩14.25 million. Growth accelerated between April and July, which accounted for 95.0% of the cumulative increase, even as stocks underwent a correction in July. Five major banks—KB Kookmin Bank, Shinhan Bank, Hana Bank, Woori Bank and Kakao Bank—contributed ₩4.9847 trillion, or 81.9%, of the increase. The figures point to heavier borrowing by existing users rather than broad account growth, as leveraged investing and worsening household cash flow increased demand for credit lines. Average overdraft interest rates rose to 5.64% at the end of July from 3.94% at the end of 2021. Separate Financial Supervisory Service data showed ₩132.1 trillion in committed limits at the end of August, including ₩67.9 trillion in unused capacity, while a separate August balance series showed a decline to ₩64.2 trillion and a utilization rate of 48.6%. The delinquency rate on other loans, including credit loans, reached 0.90% at the end of May before falling after banks wrote off and sold delinquent debt.
