Korea online-only banks near 60 million customers as focus shifts from scale to profitability

South Korea’s three online-only banks have more than 58 million customers and are nearing 60 million, helped by mobile-based services. Customer growth has not automatically translated into stable profitability, and the key second-half task is diversifying revenue. KakaoBank, K Bank and Toss Bank are expanding products, partnerships and new customer segments. They also face pressure to sustain lending to mid- to low-credit borrowers while managing asset quality and non-interest income.
