KB Kookmin Bank said on May 4 it will move to supply 1.53 trillion won worth of private mid-interest-rate loans this year.

In the first quarter, it supplied 306.8 billion won to mid- and low-credit borrowers, posting the largest performance in the banking sector. That was about 48 percent of the total supply volume from the four major commercial banks.

Private mid-interest-rate loans are unsecured credit loan products offered to customers in the bottom 50 percent of personal credit scores at rates below a certain level.

KB Kookmin Bank plans to expand supply, focusing on a dedicated credit assessment model and refinancing loan products, to improve access for mid- and low-credit borrowers. Earlier, it introduced a credit assessment model reflecting alternative information for "thin filers" with limited financial histories, and has expanded loan limits during screening.

It also launched the "KB Kookmin Do-yak Loan," which converts loans from non-bank financial institutions into loans with lower interest rates, and lowered the threshold for use by easing income and employment requirements.

It will also launch a "youth-only Saehui-mang Holssi" product that provides up to 5 million won for young people aged 34 and under. Additional benefits, including higher limits and lower interest rates, will be provided to borrowers who repay diligently and those who complete financial education.

A KB Kookmin Bank official said the bank will expand support for financially vulnerable groups and strengthen its role in inclusive finance.
