[Edaily PARK JONG-HWA Reporter Kim Se-yeon] The three internet banks (KakaoBank Corp., Kbank, and Toss Bank) posted mixed results in the first half of this year. While KakaoBank Corp. and Toss Bank recorded their best results since their founding, Kbank saw a decline in net income compared to last year. Performance in the non-interest segment was the key factor that set these companies’ first-half results apart.

Toss Bank announced on the 31st that it posted a net income of 58.9 billion won in the first half of this year. This figure represents a 46% increase from the same period last year (40.4 billion won) and marks the bank’s best-ever half-year performance.

Toss Bank’s outstanding loan balance stood at 15.6373 trillion won as of the end of June, a 3.3% increase from the same period last year. Its non-interest income and expenses for the first half showed a loss of 3.5 billion won, narrowing the deficit by 23.5 billion won compared to the 27 billion won loss recorded a year earlier. This was driven by the strengthening of non-interest business segments, such as wealth management (WM) and the debit card business. As of the end of June, the cumulative sales volume linked to Toss Bank’s “Lump-Sum Investment” service reached 29 trillion won, an increase of approximately 12 trillion won compared to the same period last year, while debit card transaction volume rose by 27% over the same period. Toss Bank plans to fully launch its fund sales brokerage business in the second half of the year.

KakaoBank Corp. also posted a net income of 328 billion won in the first half of this year, setting a new record for its best-ever half-year performance. In particular, the expansion of non-interest income—including platform and fee revenue—to 589.5 billion won contributed to the strong results. KakaoBank Corp. is diversifying its revenue streams beyond interest margins through platform-based businesses such as loan comparison, payment processing, and investment services.

Among the three internet banks, Kbank was the only one to see its first-half net profit decline compared to a year ago. Kbank, which posted a record-high net profit of 84.2 billion won in the first half of last year—its best performance since its founding—saw its net profit drop to 60.1 billion won this year. This was due to a 68% decline in non-interest income, from 73.3 billion won to 23.3 billion won, driven by factors such as a decrease in gains from bond sales.
