South Korean Banks Deploy AI to Handle Routine Financial Tasks
Kakao Bank's conversational AI service has attracted 3.4 million users in nine months, with roughly 10,000 new subscribers joining daily. The service handles transfers, account comparisons, loan calculations, and currency conversions through voice or text commands.
For managers overseeing shared accounts or group finances, the AI treasurer function automatically flags missed payments and tracks spending patterns. One 33-year-old office worker said the service simplified group account management by providing real-time alerts and spending analysis.
Who's Using These Services
Users under 20 make up 26.4% of Kakao Bank's AI users, while those 50 and older account for 25.1%. Kakao Bank deliberately lowered technical barriers so people with limited financial knowledge could access banking services.
The bank added a dedicated AI tab to its app homepage in December, which doubled daily new users from 7,000 to 25,000.
Banks Automating Loan Rate Requests
Shinhan Bank, NH Nonghyup Bank, and KB Kookmin Bank introduced an AI service that automatically requests interest rate reductions on behalf of borrowers. The feature had existed since 2019 but saw minimal adoption because customers had to gather documents and visit branches.
Under the new system, borrowers authorize banks to access their financial data once. AI then monitors credit scores and income changes, filing rate reduction requests automatically when repayment capacity improves. Each borrower can subscribe to this service at only one financial institution across the entire sector.
Pension Planning and Fraud Detection
Hana Bank launched an AI pension withdrawal advisor that recommends when and how much retirees should draw from Individual Retirement Pension accounts based on their financial situation. The tool also suggests how to allocate received funds.
Woori Bank introduced AI that screens incoming text messages for smishing scams and alerts users to suspected fraud. The bank also deployed AI counselors to handle routine questions about deposits, loans, and subscription products through mobile banking, replacing some branch consultation functions.
