566,000 Foreign Crypto Accounts in South Korea, Only 90 Trade

Lack of trading does not mean the accounts are empty. Foreign customers collectively held approximately KRW2.58 billion in cash deposits across the five exchanges at the end of July. Their cryptocurrency holdings were considerably larger at approximately KRW30.36 billion. That creates an unusual structure where a substantial pool of assets remains registered to a user group that has almost disappeared from day-to-day market activity.

The distinction affects how the size of South Korea's crypto market is measured. Registered account totals overstate the number of investors capable of participating, the data shows. Only about one in every 6,300 foreign accounts recorded any activity during July.

The restrictions emerged from a broader effort to bring cryptocurrency trading within the country's anti-money laundering framework. South Korea's Financial Services Commission required virtual asset service providers to register with the Korea Financial Intelligence Unit. Exchanges seeking to offer won markets needed relationships with banks capable of providing verified real-name accounts. Banks were expected to assess factors including exchange transparency and exposure to financial crime.

The changes dramatically reshaped the domestic industry. By the end of 2021, won-based exchanges accounted for roughly 95% of South Korea's average daily crypto trading volume, according to the Korea Financial Intelligence Unit's first comprehensive survey of the sector. The concentration meant access to a real-name banking relationship effectively determined whether an exchange could compete for the majority of Korean trading activity. For foreign users, the same infrastructure became a barrier. Passing exchange-level KYC alone is insufficient when the user cannot satisfy the banking requirements needed for normal won trading.

South Korea's crypto industry now has an economic reason to revisit the restrictions. Industry participants cited by Yonhap argue that opening domestic exchanges to foreign investors could bring additional capital into the country and expand the tax base.

There is also a market-structure argument. South Korea has historically developed a large domestic crypto market. Restricting overseas participation separates won markets from a significant part of global liquidity.

Removing those barriers would not simply reactivate all 566,352 accounts. Many may belong to users who have long since moved elsewhere. Any liberalization would still require exchanges and banks to satisfy anti-money laundering and identity requirements.

The more relevant question is whether South Korean policymakers eventually create a workable path for verified foreign investors to obtain the banking access needed to trade. Until then, the country's 566,352 foreign crypto accounts will remain a misleading measure of international participation. The 90 active accounts provide a much closer indication of how little foreign activity currently reaches its major exchanges.
