"Given the current situation on interest rates, I think that we could generate profits in 2020," Shim told Yonhap News Agency in an interview last Friday, two days before the bank launched its operations.

Shim said the bank is reviewing plans to launch a credit card business "as early as possible."

In just two days since launching operations on Tuesday, K-Bank, formed by a consortium of KT Corp., Woori Bank and 19 other companies, attracted more than 60,000 accounts.

The pace of growth in K-Bank's customer base appears to be faster than originally expected. The average monthly number of new Internet banking accounts by the nation's 16 commercial banks stood at about 12,000.

Internet banks offer banking and other financial services without physical branch networks.

K-Bank, which is open around the clock, offers ordinary deposits, time deposits and loans with more favorable interest rates than the ones offered by traditional banks.

Among the new services by the Internet banks are new credit assessments based on big data, wealth management by artificial intelligence systems and voice recognition banking services.

One of key hurdles for K-Bank's potential growth is a law that bars a non-financial firm from owning more than 4 percent of stake at a financial firm.

Shim urged lawmakers to ease the law to allow the bank to raise new capital.

K-Bank was launched with a paid-in capital of 250 billion won.

To increase lending and meet the capital adequacy ratio established under the Bank of International Settlements, Shim said the bank must decide on a capital hike before next year's annual shareholder meeting. (Yonhap)
