KB Kookmin Bank said on Thursday it ranked first across the financial sector in assets under default option pension products as of the end of the third quarter.

The default option system was introduced in 2023 to prevent retirement pension funds from being left idle at low interest rates and to improve returns.

According to the Ministry of Employment and Labor’s disclosure on the key status of the default option system for the third quarter of 2025, KB Kookmin Bank’s default option assets stood at 10.3 trillion won, the largest among 41 providers.

By product risk level, assets in stable investment-type portfolios or higher accounted for 16.8 percent of total default option assets, the highest share among banks.

Returns by investor risk profile were higher in portfolios with a greater share of investment products, in the order of aggressive, neutral, stable investment and conservative types.

A KB Kookmin Bank official said the bank is doing its best to provide optimal default option portfolios to help clients grow their pension assets steadily, and added it would continue to contribute to clients’ long-term asset formation based on differentiated management capabilities.
