A string of hacking incidents in South Korea’s financial sector has led to confirmed personal data leaks at savings banks and mutual finance groups, prompting authorities to step up inspections and security requirements. Banks are moving to raise cybersecurity spending and expand fraud prevention systems using AI. Market volatility and a steep stock selloff also drew a policy response. Political debate intensified over postponing digital asset taxation and regulating exchange shareholders.

Joint lending between internet-only banks and regional banks is expanding from personal credit loans to business finance. South Korea\'s Financial Services Commission designated a joint corporate loan service by Toss Bank and Gwangju Bank as an innovative financial service, the second such case after KakaoBank and Busan Bank. The model splits screening and funding between two banks and aims to process many steps digitally. Authorities are also revising rules on in-person work for internet-only banks.
