South Korean Banks Concede Remittance Market to Crypto Exchanges
What You Need to Know
- Crypto exchanges processed 163.55 trillion won in cross-border transfers in 2024, exceeding South Korea’s five largest banks.
- Cross-border crypto volume surged 380% from 2022 to 2024, while major banks grew remittance volume only 20% over same period.
- Lower crypto remittance fees than traditional banks drove adoption among South Koreans abroad and Southeast Asian traders.
- South Korean banks acquired stakes in crypto exchanges rather than competing on fees, mirroring China’s mobile payment disruption pattern.
South Korean crypto exchanges processed more cross-border transfers last year than the country’s five largest banks, a first, and the gap is already wide enough that banks are responding by buying into the exchanges they cannot beat.
The five major won-denominated exchanges recorded 163.55 trillion won ($125.8 billion) in cross-border volume in 2024, a 380% increase from 34.02 trillion won in 2022. Over the same period, the five biggest banks grew their foreign-currency remittance volume by just 20%, reaching 159 trillion won. The driver, according to Dongguk University professor Hwang Seok-jin, is straightforward: crypto remittance fees are materially lower than bank rates, and South Koreans abroad alongside traders in Southeast Asia and the Middle East have voted accordingly with their flows. This pattern echoes what happened with mobile payments in China a decade ago, where WeChat Pay and Alipay displaced bank transfer rails not through regulation but through price and speed, until banks eventually acquired stakes in the disruptors.
The response from South Korean banks has been acquisitive rather than defensive, which suggests they have already conceded the fee competition.
Hana Bank committed roughly 1 trillion won ($720 million) for a 6.55% stake in Dunamu, Upbit’s parent. KBank, already Upbit’s banking partner, has completed testing for a wallet-based remittance system using Ripple’s Palisade software, targeting transfers to the UAE and Thailand. Toss Bank, with over 15 million customers, announced a deal with Solana focused on cross-border payments and settlements. Samsung Securities, Samsung SDS, and Samsung Card jointly took a 4% stake in the same platform. A Tiger Research survey of 150 institutions found competition concentrating around stablecoins, security token offerings, and crypto asset custody, which maps exactly to where margin is likely to migrate once remittance volume is commoditized.
The Regulatory Bottleneck
The one variable that could reshape this entire picture is stalled. South Korea’s Digital Asset Basic Act, which would introduce licensing, disclosure requirements, insider trading prohibitions, and a 50 billion won ($35 million) capital floor for stablecoin issuers, has been delayed by the National Assembly until at least late this year following the June 3 local elections. The holdup is a jurisdictional dispute between the Financial Services Commission and the Bank of Korea over stablecoin oversight: the BOK wants bank consortia to hold majority ownership of stablecoin issuers, the FSC considers that arrangement anticompetitive. Until that is resolved, the capital commitments from Samsung, Hana, and Toss are being placed into a regulatory environment that remains undefined on its most consequential question.
