Crypto Exchange Partnerships Fuel Fraudulent Account Surge

Banks Under Fire as Crypto Partnerships Fuel Surge in Fraudulent Accounts

SEOUL – south Korea’s leading commercial banks are facing increasing scrutiny following a dramatic uptick in fraudulent accounts linked to their collaborations with cryptocurrency exchanges. These partnerships,designed to streamline virtual asset transactions,are now at the center of a growing concern over financial security.

Data analyzed by the Maeil Business Newspaper, sourced from the Financial Supervisory service (FSS), reveals a stark correlation between bank-exchange partnerships and reported fraud cases. KB Kookmin Bank, wich initiated its collaboration with the crypto exchange Bithumb in late March 2025, has witnessed a meaningful escalation in fraud-related accounts. The bank’s figures show a concerning rise from 100 fraud-linked accounts in February to 148 in March,and a further spike to 208 by mid-July.

In contrast, NH Nonghyup bank, which previously partnered with Bithumb before transferring the agreement to KB kookmin bank, has seen a notable decrease in fraud incidents after severing ties. After peaking at 219 fraud-related accounts in April, the number plummeted to 89 in May and further declined to 68 in June, making it the lowest among the nation’s top five commercial banks. This trend suggests a direct link between the banking partnerships and the prevalence of fraudulent activities.

The allure for commercial banks is undeniable. These partnerships promise a consistent influx of low-cost deposits and offer a valuable avenue for customer base expansion. This potential for growth has fueled lobbying efforts by these lenders to relax existing regulations, which currently limit each cryptocurrency exchange to a single banking partner for issuing real-name, won-denominated accounts.

However,the escalating number of fraud cases has reinforced the resolve of financial authorities to maintain the current regulatory structure. According to FSS data compiled by Lee Yang-soo, a lawmaker from the People Power Party, the nation’s five largest banks – KB Kookmin Bank, Shinhan Bank, Hana Bank, Woori Bank, and NH Nonghyup Bank – recorded a total of 7,991 fraud cases involving bank accounts in 2024.

“Protecting customers must remain the banks’ core responsibility. Instead of chasing short-term gains through crypto partnerships, banks should focus on building stronger systems and safeguarding users,” lee emphasized. This statement underscores a critical debate: whether the pursuit of new revenue streams through cryptocurrency ventures outweighs the essential obligation of banks to ensure customer security and the integrity of the financial system.As the digital asset landscape continues to evolve, the challenge lies in balancing innovation with robust risk management and consumer protection.
