Kbank’s Upbit Customer Deposits Total $2.2B
Kbank, an internet-only bank in South Korea, is facing criticism due to its relatively high proportion of cryptocurrency customer deposits compared to other banks. Kbank reportedly manages approximately KRW 3 trillion (equivalent to $2.2 billion) in deposits from customers of cryptocurrency exchange Upbit, which accounts for about 18% of its total customer deposits.
This percentage stands out, being notably higher than other banks that provide accounts to the other four crypto-to-fiat exchanges in Korea. That is according to a report by Maeil Business Newspaper, which obtained documents submitted to lawmaker Kim Hee-gon by the Financial Services Commission (FSC).
According to Korean law, crypto exchanges must secure real-name bank accounts from banks to offer crypto trading services against the Korean won. Kbank offers its accounts to Upbit, the dominant player in the Korean crypto market.

Notable exposure to crypto exchange
The FSC documents showed that Kbank’s Upbit customer deposits totaled KRW 3.09 trillion, making up 18% of its total deposits, which amount to KRW 17.2 trillion.
In a striking contrast, Nonghyup Bank had 0.2% of its deposits, equivalent to KRW 557.8 billion, in Bithumb, which is the nation’s second-largest cryptocurrency exchange. Kakaobank, another internet-only bank, had 0.3% (KRW 112.2 billion) of its deposits in Coinone. Shinhan Bank held 0.01% (KRW 43 billion) in Korbit, and Jeonbuk Bank had a similarly small 0.02% (KRW 4.2 billion) in Gopax.
Lawmaker Kim pointed out that Kbank has become a bank dedicated to crypto trading. Kim proposed that financial authorities take proactive measures to assess the potential risks that may emerge when Kbank utilizes Upbit customer deposits as a basis for offering credit loans. Such risky financial practices could potentially result in higher loan defaults and the emergence of a greater number of individuals with poor credit histories, which could ultimately jeopardize the stability of the financial market.
Regulatory gap
The current Financial Transaction Reporting Act mandates that virtual asset service providers (VASPs) segregate customer deposits from their own assets as a measure to combat money laundering. However, it has been noted that there are regulatory gaps stemming from the absence of specific guidelines for the custody of these deposits.
According to the Financial Supervisory Service (FSS), Nonghyup and Kakaobank store deposits in separate accounts within the bank. On the other hand, Kbank and Jeonbuk Bank keep deposits in corporate accounts under their respective exchange partners’ names.
When deposits are stored in separate accounts within the bank, only the bank has access to those funds, and they are essentially operated in a manner similar to a trust, preventing the bank from using the funds arbitrarily. In contrast, funds held in corporate accounts can be used by the bank as a source for lending. Lawmaker Kim warned that in scenarios such as exchange bankruptcies or similar situations, banks holding customer funds in corporate accounts could face difficulties in ensuring customer protection.
Each of these banks receives reserve funds from crypto exchanges in anticipation of potential compensation requirements in the event of unforeseen losses. The FSS states that as of the end of last month, the reserve amounts held by each bank were as follows: Kbank had KRW 200 billion, Nonghyup Bank had KRW 100 billion, Kakao Bank had KRW 73 billion, and both Shinhan Bank and Jeonbuk Bank had KRW 30 billion.
Kbank’s Upbit customer deposits are approximately 72 times larger than Shinhan Bank’s Korbit customer deposits. However, the reserve amounts held by Kbank are only 6.7 times greater than those held by Shinhan. Lawmaker Kim emphasized the importance of banks maintaining reserve funds that are proportional to the customer deposits held in their partner crypto exchanges.
Signs of recovery
Meanwhile, the Korean cryptocurrency industry, which faced a downturn in the latter half of last year due to events like the Terra collapse and FTX’s bankruptcy, has exhibited signs of recovery in the first half of this year.
The Financial Intelligence Unit (FIU) of the FSC recently reported that the cryptocurrency market cap in South Korea has reached KRW 28.4 trillion as of the end of June this year. This reflects a 46% increase compared to the end of last year when it stood at KRW 19.4 trillion. Additionally, the total operating profit of domestic exchanges surged by 82% to KRW 227.3 billion over the past six months, compared to the previous figure of KRW 124.9 billion.
The total market’s max drawdown (MDD) was 62%. MDD assesses the extent to which an asset has declined in value from its highest point to its lowest point within a specific time frame, before experiencing a recovery. The FIU considers this MDD to be high, urging investor caution.
