South Korea is ramping up its cryptocurrency market oversight by integrating artificial intelligence tools to detect suspicious trading activities. The Financial Supervisory Service (FSS) is currently reviewing unusual price movements in the ZKsync token on Upbit, which occurred during a system maintenance window in early February 2026. This move is part of a broader strategy to enhance market integrity and prevent manipulation, with regulators viewing exchanges as critical financial infrastructure. The FSS's initiative includes upgrading its crypto intelligence system to automatically identify potential manipulation across various time frames. Additionally, the Financial Services Commission (FSC) is considering mechanisms for pre-emptive fund freezes to curb illicit activities during investigations. This regulatory push aligns with global trends towards stricter market surveillance and enforcement, aiming to set higher compliance standards for exchanges and market participants in South Korea.
