South Korea's Financial Services Commission referred suspects in two crypto market manipulation cases to prosecutors Wednesday after discussions at its 12th regular meeting. The cases involve individuals accused of using different methods to distort crypto prices and profit from artificial market activity. The referrals continue South Korea's tightening oversight of virtual assets after years of heavy retail participation in crypto trading, with price manipulation a priority for regulators seeking to protect smaller investors.
FSC Accuses Whale of Cross-Exchange Price Manipulation
In one case, the FSC accused a crypto whale of using tens of billions of Korean won over roughly two months to manipulate the price of a token listed on both domestic and overseas exchanges. Based on current rates, 10 billion won is equivalent to about $6.4 million.
The suspect allegedly accumulated nearly half of the token's circulating supply, giving them significant control over available market liquidity. According to the FSC, the suspect then pushed the token price higher on overseas exchanges, encouraged domestic investors to buy, and later sold their holdings on a local exchange.
The alleged structure shows how manipulation can move across jurisdictions. A price increase on overseas venues can create the appearance of global demand, while domestic investors may react to the price movement without seeing how concentrated the supply has become.
Once the suspect sold into the demand they helped create, retail investors suffered significant losses, according to the regulator. The case highlights the risk of thinly traded tokens where a single large holder can restrict supply, influence price discovery, and exit before smaller buyers understand the source of the move.
Second Case Involves API Trading and Limit Order Tactics
The second case involved a different trading pattern. The FSC said another individual allegedly used API channels to repeatedly place small market buy and sell orders, creating the appearance of active trading. At the same time, the suspect allegedly submitted high-priced limit buy orders through a web channel to push the price higher.
That type of activity can create a false impression of liquidity and momentum. Small repeated trades may make a token look active, while aggressive limit orders can suggest stronger demand than actually exists. Other investors may then enter the market believing the price move is supported by genuine buying interest.
After attracting buyers, the suspect allegedly sold holdings in portions to realize profits. The staged selling approach can help avoid an immediate collapse while still allowing the manipulator to exit into artificial demand.
The case shows why regulators are paying closer attention to order-book behavior, API usage, and the difference between visible trading activity and genuine market interest.
FSC Warns Investors and Plans System Improvements
The FSC warned investors against chasing virtual assets whose prices and trading volumes rise sharply without a reasonable cause. "Investors should refrain from chasing virtual assets whose prices and trading volumes surge (or spike sharply) without any reasonable cause," the regulator said in a translated statement.
The agency specifically pointed to pump-and-dump schemes that reduce available supply to inflate prices before a sell-off. "In particular, the so-called 'pump-and-dump' schemes … artificially reduce available supply to inflate prices, and the subsequent sell-off often leads to a sharp price collapse," the FSC said.
The watchdog also said it plans to improve its warning system for highly concentrated crypto trading and strengthen its investigative framework to detect unfair practices more quickly.
