South Korea uncovers 40 crypto manipulation cases, refers 30 to prosecutors

South Korea’s Financial Services Commission and Financial Supervisory Service have completed investigations into more than 40 suspected cases of cryptocurrency market manipulation since the Virtual Asset User Protection Act took effect in July 2024, with over 30 cases referred to prosecutors.

The announcement, made on July 20 by the Financial Services Commission (FSC) and the Financial Supervisory Service (FSS), shows the government’s increasingly aggressive approach toward eliminating unfair trading practices in one of Asia’s largest crypto markets.

The cases span price manipulation, fraudulent trading, misleading promotions, and sophisticated trading schemes that allegedly generated billions of won in illicit profits.

Regulators reveal the scale of crypto market abuse

The enforcement update comes exactly two years after South Korea implemented the Virtual Asset User Protection Act, legislation designed to strengthen investor protection and establish a legal framework for policing digital asset markets.

According to the FSC, authorities have completed investigations into over 40 unfair trading cases, with more than 30 referred to prosecutors or investigative agencies.

The investigations identified 25 suspected offenders, while the average illicit profit per case reached approximately 1.4 billion won (around $1 million).

Most of the investigations involved market manipulation, although regulators also uncovered fraudulent schemes involving misleading social media promotions, coordinated trading activity, and deceptive practices linked to token issuers.

Among the manipulation techniques cited by regulators were: High-frequency API-driven trading to artificially influence prices. Coordinated “racehorse” trading designed to push tokens into top-performing rankings.

“Cage” manipulation exploiting temporary deposit and withdrawal restrictions on exchanges. Large-scale coordinated trading involving so-called crypto “whales.”

Lastly, false information campaigns designed to inflate token prices before insiders sold their holdings.

The findings reinforce regulators’ longstanding concern that market abuse in crypto increasingly mirrors sophisticated manipulation techniques seen in traditional financial markets.

AI surveillance becomes the next phase of enforcement

South Korean authorities say enforcement will become even more technology-driven.

The FSC announced plans to strengthen market surveillance by expanding the use of artificial intelligence, digital forensics, and enhanced monitoring systems capable of detecting suspicious trading activity more efficiently.

 “Financial authorities will continue strengthening efforts to eradicate unfair trading in the virtual asset market, including improving market surveillance and investigation efficiency through AI.” Financial Services Commission, official press release.

Since the law took effect, exchanges have also been required to operate continuous abnormal transaction monitoring systems while reporting suspicious activity directly to regulators.

Authorities say this coordinated monitoring framework has significantly accelerated investigations compared with previous years.

Tougher oversight raises compliance pressure

For crypto investors, the latest enforcement figures underscore South Korea’s determination to transform its digital asset market into one governed by rules comparable to traditional financial markets.

The Virtual Asset User Protection Act prohibits insider trading, market manipulation, and fraudulent transactions, with violators facing criminal penalties, substantial fines, and administrative sanctions depending on the severity of misconduct.

Regulators believe stronger enforcement is essential as institutional participation in digital assets gradually expands across Asia.

The latest announcement also follows several high-profile enforcement actions in South Korea’s crypto sector over the past year, reinforcing a broader regulatory shift toward stricter supervision of exchanges and trading platforms.

“The financial authorities have investigated more than 40 unfair trading cases since the law took effect and referred over 30 cases involving market manipulation and fraudulent trading to investigative agencies.”

What crypto investors should watch next

For crypto investors, South Korea’s latest enforcement campaign represents more than a domestic regulatory update.

The country remains one of the world’s most active digital asset markets, often influencing regional trading sentiment and regulatory policy across Asia.

A more aggressive enforcement environment could improve market integrity over the long term, but it may also increase compliance costs for exchanges, token issuers, and trading firms operating in the jurisdiction.

The FSC has indicated that additional investigations are ongoing and that authorities will continue expanding surveillance capabilities as digital asset markets evolve.

That suggests market participants should expect faster detection of suspicious trading patterns and more frequent enforcement actions against individuals and organizations found violating the law.
