South Korean Regulators Forge Ahead with Custody Policy Reforms as Investor Losses Mount

Seoul scrambles to rewrite the rulebook as crypto custodianship failures leave a trail of red ink.

The Regulatory Reckoning

Mounting financial pain is forcing the hand of South Korea's financial watchdogs. The Financial Services Commission (FSA), facing intense public and political pressure, is now fast-tracking a comprehensive overhaul of digital asset custody regulations. The move comes after a series of high-profile platform failures exposed gaping holes in how investors' crypto holdings are safeguarded—or more accurately, weren't.

Closing the Vault

The planned reforms target the core infrastructure of trust. Expect stricter capital requirements for custodians, mandatory proof-of-reserves audits conducted by third parties, and a clear legal separation between client assets and platform operating funds. The goal is unambiguous: prevent another case where user funds simply vanish into thin air or get commingled for risky ventures. It's the financial equivalent of moving from a cardboard box under the bed to a bank-grade vault.

The Price of Progress

This regulatory pivot isn't born from abstract principle—it's a direct response to quantifiable losses that have shaken retail confidence. While the reforms promise a more secure future, they also signal the end of the wild west era for Korean crypto exchanges. Compliance costs will skyrocket, potentially squeezing out smaller players and consolidating power among the majors who can afford the new security overhead. Another classic finance tale: the little guy gets burned, so they build a bigger, more expensive fence that only the big guys can afford to maintain.

The FSA's commitment is a necessary step toward maturity, but it underscores a painful truth in crypto's growth: sometimes, the market only learns the value of a seatbelt after a major crash.

Koo says government only holds crypto from seizures or enforcement measures

Seeking to address concerns over recent failures, Koo said the government WOULD urgently strengthen its crypto security framework. The minister also emphasized that the state does not hold crypto as an investment, but only takes custody of assets acquired legally.

He commented on X: “For reference, the government does not hold digital assets other than those acquired in the course of legal enforcement processes such as seizure.”

Per last week’s report, in November 2021, Gangnam Police seized 22 Bitcoins during a probe into a hacking case linked to the A Coin Foundation. However, the officers entrusted a third-party company with the seized crypto and failed to keep the private keys, resulting in a loss of roughly $1.4 million at the time.

So far, the police have arrested a pair of individuals in connection with the case, and prosecutors are investigating potential bribery.

The private key lapse revealed shortcomings in the technical controls surrounding state-held digital assets. The incident, a Hansung University professor remarked, demonstrated the tax authorities’ fundamental ignorance of the workings of digital assets and inflicted losses of billions on the national budget.

Bithumb experienced $40 billion system failure  

South Korea’s Bithumb had major system bugs earlier in February that left the platform vulnerable to possible sabotage, and which permitted a misdirected transfer exceeding $40 billion.

During a promotional event, customers received 620,000 Bitcoins instead of 620,000 won ($426), driving Bitcoin’s price down by 17%. Most mistaken transactions were reversed on the platform, but approximately 13 billion won ($9 million) couldn’t be recovered because some users had withdrawn or sold the funds. 

Lee Chan-jin, head of the FSS, called the situation disastrous for anyone who mistakenly sold their credited Bitcoin, adding that prices have risen since Friday and that those ordered to return it risk losing money. The glitch also exposed serious problems with exchanges’ internal accounting systems, he added.

Meanwhile, legal analysts still differ on whether recipients who cashed out the crypto may face prosecution, given a 2021 Supreme Court decision that cryptocurrency isn’t deemed “property” under Korean criminal statutes.
