Kakao Pay Faces ₩15 Billion Fine Over Alleged Unauthorized Data Transfer to China’s Alipay
SEOUL, South Korea — April 9, 2025 — South Korea’s Financial Supervisory Service (FSS) has moved to impose a ₩15 billion (approx. $11.2 million USD) penalty on fintech platform Kakao Pay Corp. following allegations of unlawful user data sharing with Alipay, a Chinese digital payments giant affiliated with Ant Group, the fintech arm of Alibaba Group Holding Ltd.
The penalty comes after an extensive investigation into Kakao Pay’s handling of personal information, in which the FSS determined that the company had transferred the private data of over 40 million users—reportedly 40.45 million accounts—to Alipay without explicit user consent. This alleged breach occurred over a five-year period, from April 2018 through May 2023, and violates South Korea’s Credit Information Use and Protection Act.
Regulatory Oversight Intensifies in the Fintech Sector
The FSS held a sanctions deliberation committee earlier this month to review the violations. While the 15 billion won fine targets the company, the watchdog also indicated leniency toward individual employees, suggesting lighter disciplinary measures for staff involved in the process.
The Financial Services Commission (FSC), South Korea’s top financial policymaking body, is now tasked with determining whether to uphold or adjust the proposed sanctions based on both the FSS’s findings and Kakao Pay’s official explanation, which is still pending final submission.
This development is part of a broader regulatory tightening across Asia, where governments are increasing scrutiny on data privacy, especially concerning cross-border data transfers involving Chinese tech companies. The South Korean government, in particular, has grown increasingly vigilant following concerns about foreign influence and data security risks.
Kakao Pay’s Strategic Ties with Alipay Under the Microscope
Founded in 2017, Kakao Pay is a subsidiary of Kakao Corp., the tech conglomerate behind the popular messaging app KakaoTalk. It has been a key player in South Korea’s fast-growing digital payments market, facilitating mobile transactions, investment products, and insurance services.
Kakao Pay has maintained a strategic partnership with Alipay since its early days. Alipay was an early investor, and the collaboration enabled Korean users to process international transactions with greater ease. However, the relationship has raised questions about data sovereignty and whether Chinese tech firms have indirect access to Korean users’ financial data.
Industry experts point out that Kakao Pay may have underestimated the regulatory boundaries surrounding sensitive user data, especially as global standards for data protection and consent continue to tighten.
Kakao Pay Responds: “We Will Cooperate Fully”
In a brief statement issued Wednesday, Kakao Pay spokespersons said the company is “closely reviewing the FSS findings” and will “actively engage in the process to clarify the facts and take corrective measures.”
They further emphasized Kakao Pay’s commitment to data privacy and compliance, stating that user trust remains the company’s “top priority.”
Repercussions and Investor Sentiment
News of the proposed fine sent Kakao Pay’s shares (KRX:377300) falling by 3.2% in early afternoon trading on the KOSPI, reflecting growing investor concern about potential reputational and regulatory risks.
Market analysts at NH Investment & Securities warned that while the fine is manageable financially, the long-term impact on user trust and global expansion efforts, especially in China and Southeast Asia, could be more substantial.
