South Korea’s FSS Deploys AI to Detect Crypto Market Manipulation

South Korea’s Financial Supervisory Service (FSS) has rolled out AI-driven surveillance within its Virtual Assets Intelligence System (VISTA) to detect and prioritize market manipulation in the country’s expanding crypto sector. The upgraded system uses automated, sliding-window analysis of real-time transaction data—price moves, volatility, volume spikes and short-lived anomalies—to flag likely wash trading, pump-and-dump schemes and coordinated trades across related accounts. Internal tests reportedly recovered all previously known manipulation periods and identified additional suspicious windows missed by manual review. Funding is secured for phased AI enhancements through 2026 to add network-detection of coordinated accounts, large-scale analysis of trading-related text (narrative engineering), and tracing of fund origins; regulators are also considering proactive measures such as temporary transaction or payment suspensions to prevent laundering of illicit gains. Strengths include continuous monitoring, faster prioritization of high-risk intervals and improved detection of subtle patterns; limitations remain — off-platform coordination, narrative-driven manipulation and false positives still require human review. The move signals tighter enforcement, greater exchange cooperation requirements and increased cross-venue monitoring. For traders: expect heightened surveillance, faster regulatory responses to suspicious flows and increased compliance pressure on exchanges, which could reduce manipulative spikes but also increase short-term volatility around enforcement actions.
