The South Korea Financial Supervisory Service has selected 42 highly indebted business groups as 2026 main debtor groups, based on their year-end 2025 group-wide borrowings and bank credit exposure. The designation applies to groups with borrowings above KRW 2.5569 trillion and outstanding credit extended from banks above KRW 1.5032 trillion. At the end of December 2025, banks' outstanding credit to enterprises totaled KRW 2,173.2 trillion, up KRW 168.9 trillion or 8.4% from a year earlier. The 42 designated groups accounted for KRW 386.9 trillion of that bank credit, up KRW 15.1 trillion or 4.1% year on year, while their total borrowings reached KRW 743.9 trillion, up KRW 35.1 trillion or 5.0%. Principal creditor banks will assess the financial stability of the selected groups and enter into restructuring and turnaround agreements with financially vulnerable groups to manage credit risk.
