South Korea maintains single-bank policy for crypto exchanges
South Korean financial regulators have decided, at least for the time being, to maintain the current policy requiring cryptocurrency exchanges to partner with only one bank, according to a report from the Seoul Economic Daily.

Dominance and money laundering concerns
A government official cited concerns that allowing multiple banking relationships could potentially strengthen market dominance by leading platforms and increase money laundering risks. Regulators plan to revisit the issue after monitoring new developments following upcoming regulations that will permit institutional participation in the crypto market.
This decision runs counter to a recent proposal put forward by the People Power Party (PPP) ahead of the presidential election that seeks to eliminate the one-bank-per-exchange requirement. Bizwatch reported that while the crypto industry initially supported the removal of this restriction unanimously, opinions have recently diverged among market participants.
Divided industry
Major exchanges offering Korean won-based trading are mostly against the potential policy change. Except for Upbit, the country's largest platform, competitors express concern that modifying the rules could weaken their existing banking relationships if more financial institutions choose to partner with the market leader.
Conversely, crypto-only exchanges, which cannot offer Korean won trading services, generally favor eliminating banking restrictions. These platforms believe relaxed regulations could create more opportunities to establish banking partnerships. Under current rules, virtual asset service providers must secure real-name accounts from a local bank to offer Korean won trading, placing those without such accounts at a competitive disadvantage.
Banks also want change
Korean commercial banks align with crypto-only exchanges in supporting the easing of banking regulations. Jung Jin-wan, CEO of key financial institution Woori Bank, recently called for allowing multiple banks to serve individual crypto exchanges. He argues that the current one-bank-per-exchange system not only undermines systemic stability but also limits customer choice.
While an official from a crypto-to-fiat exchange acknowledged the need for eventual reform of the one-bank-per-exchange system to improve customer options and market development, they also pointed out that industry stakeholders hold different views depending on their position in the market. The official said that dominant platforms perceive minimal practical benefits from permitting multiple banking relationships.
