Regulatory Action Overview
According to ChainCatcher, South Korea's Financial Commission (FSC) has filed lawsuits in two separate crypto market manipulation cases during its 12th regular meeting. The cases highlight sophisticated manipulation techniques involving substantial capital and directly harming domestic retail investors. The FSC also issued a public warning and committed to upgrading oversight measures, including enhanced reporting of large holdings and improvements to the market early-warning system.
Case One: Whale Cornering and Cross-Exchange Arbitrage
In the first case, a so-called 'whale' investor spent hundreds of billions of Korean won (roughly millions of RMB) to acquire approximately half of the total global circulating supply of a specific crypto asset. The investor first artificially drove up the asset's price on an overseas exchange, then exploited the price correlation between exchanges to sell the tokens at a high price on a domestic exchange. Local investors who followed the momentum ended up bearing the losses when the price corrected. This scheme — controlling supply to create cross-border price gaps — poses a serious threat to market fairness.
Case Two: API Wash Trading and Pump-and-Dump
The second case involves a token commonly referred to as a 'Kimchi coin.' The suspect used API channels to submit market buy and sell orders repeatedly within one second, generating fake trading volume and luring retail traders. Simultaneously, the suspect placed high-priced buy orders on a web interface to artificially inflate the price. Once buying pressure built up, the suspect sold off holdings in batches, executing a classic pump-and-dump. This technically sophisticated wash trading method, though not uncommon in Korea's crypto scene, was precisely identified and prosecuted in this instance, reflecting improved regulatory capabilities.
Regulatory Implications and Investor Warnings
The FSC explicitly warned investors to be wary of crypto assets whose prices and trading volumes spike suddenly without clear fundamental reasons — a typical sign of market manipulation. The agency announced it would strengthen the frequency and transparency of large-holder position disclosures and establish a more responsive market early-warning system to detect and deter similar manipulative behavior. These prosecutions add to the global trend of tightening enforcement against crypto market abuse, urging both trading platforms and investors to raise compliance awareness.
