The South Korean Fair Trade Commission (FTC) has initiated a re-investigation into allegations of collusion regarding the loan-to-value (LTV) ratios among the country's four major banks, specifically targeting KB Kookmin Bank and Hana Bank. This inquiry follows suspicions that these banks may have coordinated their LTV policies, which are crucial for determining the maximum amount of loan a borrower can secure against their property. The FTC aims to ensure compliance with fair trading practices and prevent anti-competitive behavior in the banking sector.
