South Korea’s FSS Unveils AI Upgrades to Detect Crypto Abuse

South Korea’s financial watchdog is expanding its use of artificial intelligence to police digital asset markets, signaling a move toward automated, data-driven enforcement as trading activity grows more complex. The Financial Supervisory Service (FSS) announced an upgrade to its Virtual Assets Intelligence System for Trading Analysis (VISTA), adding an automated detection algorithm designed to identify potential price-manipulation periods without manual intervention. The system employs a sliding-window grid search to comb through every sub-period within a dataset, offering a more exhaustive view of manipulation windows than traditional methods. The upgrade comes with a 170 million won budget for 2026 and is set to roll out in stages through the year, with additional features planned later. It sits alongside broader AI monitoring initiatives in Korea’s financial world, including plans for an AI-driven stock market monitor by the Korea Exchange and discussions of a pre-emptive payment-suspension mechanism to block suspicious transactions.

Key takeaways

• The FSS expanded VISTA with an automated detection module that searches for manipulation windows using a sliding-window grid approach, reducing reliance on manual review.
• Performance tests reportedly showed the system captured all previously identified manipulation periods and flagged additional suspicious intervals that were hard to detect with traditional analysis.
• The 2026 budget for AI upgrades stands at 170 million won, with phased deployments planned through the end of the year.
• Future upgrades target networks of coordinated trading accounts, automated analysis of abnormal trading-related text across thousands of assets, and tracing the origin of funds used in manipulation.
• The push aligns with a broader regulatory effort in Korea to apply AI surveillance to crypto and broader markets, including a planned pre-emptive freeze mechanism and an AI-based stock market monitoring system by the Korea Exchange.

Market context: The upgrade reflects a broader trend of AI-based market surveillance expanding beyond crypto into traditional capital markets in Korea, as regulators seek faster detection of manipulation and easier enforcement, potentially shaping liquidity and risk sentiment in digital-asset trading.

Why it matters

The move marks a shift from labor-intensive, case-by-case investigations to automated, scalable oversight. For exchanges and firms operating within South Korea’s crypto ecosystem, the enhanced capabilities could shorten investigation cycles, improve the accuracy of flagging suspicious activity, and normalize a higher baseline of regulatory scrutiny. Yet as automated tooling accelerates detection, questions naturally arise about due process, transparency, and the limits of algorithmic enforcement in rapidly evolving markets.

Investors may experience a more predictable regulatory environment as manipulation signals are identified and acted upon with greater speed. At the same time, the deployment of AI-driven surveillance carries implications for how liquidity is managed and how market participants calibrate risk, particularly in periods of heightened volatility or unusual cross-asset activity. The initiative sits within a broader global trend toward technology-enabled oversight, where regulators are increasingly relying on data-intensive tools to monitor complex trading networks and to trace the flow of funds in ways that were not feasible a few years ago.

Beyond crypto, Korea is expanding AI-based monitoring into stock markets, with regulators aiming to detect and deter price manipulation more efficiently. The convergence of crypto and traditional markets under a shared AI-aided regulatory umbrella underscores a future in which automated signals, risk scoring, and pre-emptive intervention could become the norm rather than the exception. As these systems mature, stakeholders—ranging from exchanges and developers to traders and institutions—will need to adapt to tighter, faster feedback loops and a heightened emphasis on data provenance and auditability.

What to watch next

• Stage-by-stage rollout of the VISTA upgrades through 2026, with specific milestones announced by the FSS.
• Details on tools to identify networks of coordinated trading accounts and to analyze abnormal trading-related text across thousands of assets.
• Progress and regulatory guidance on the proposed payment-suspension mechanism to block transactions preemptively in suspected manipulation cases.
• The Korea Exchange’s deployment of an AI-driven market monitoring system and any observed impact on stock manipulation detection.

AI-powered oversight expands as Korea upgrades crypto surveillance

In Seoul, regulators are moving toward a model where automated intelligence conducts the initial sweep of market activity, flagging anomalies for human review rather than awaiting manual detection from the outset. The FSS’s VISTA upgrade represents a deliberate shift toward machine-assisted enforcement, tying together data-rich analysis with structured investigations to improve both speed and accuracy in identifying manipulation schemes.

Central to this upgrade is the sliding-window grid search technique. By analyzing every possible sub-period within a dataset, the system can pinpoint precise windows where price actions might indicate manipulation, such as spoofing, layering, or wash trading. This approach eliminates the need for investigators to eyeball timeframes and instead offers a quantitative map of suspicious activity across a trading history. According to the FSS, tests conducted on completed cases validated that all previously known manipulation periods were detected, while the algorithm also surfaced additional intervals that traditional analysis had missed.

The upgrade’s scope extends beyond detection alone. The FSS has earmarked a 170 million won budget for 2026 to fund phased AI enhancements, with the expectation that new modules will be rolled out over the course of the year. Future capabilities include automatically identifying networks of coordinated trading accounts, scanning thousands of crypto assets for abnormal trading-related text, and tracing the origin of funds used in manipulation. These features align with a broader regulatory ambition to close gaps in enforcement through data-driven tools, rather than relying solely on post-hoc investigations after irregular activity has already occurred.

The initiative is not isolated to the crypto realm. Korea’s financial watchdogs are coordinating AI-enhanced surveillance across capital markets to bolster early detection of manipulation. On the same day the FSS highlighted its VISTA upgrade, the Financial Services Commission announced that the Korea Exchange will operate an AI-driven market monitoring system intended to strengthen early detection of stock price manipulation. The parallel developments—crypto- and equity-market AI surveillance—signal a national push toward a unified, tech-enabled enforcement framework.

Amid these developments, local reporting surfaced a potential pre-emptive tool: a payment-suspension system that could block transactions before illicit proceeds are laundered. While such a system would require careful governance and clear due-process protections, its consideration illustrates the regulators’ willingness to leverage technology to disrupt illicit activity at or before the point of execution. Taken together, the moves depict a regulatory environment that is becoming faster, more anticipatory, and more capable of handling the complexity of modern digital markets.

For participants in Korea’s crypto space, the implications are nuanced. Automated detection can improve the integrity of markets by narrowing the window for manipulation and by providing timely, auditable signals for enforcement. Yet as enforcement tools become more sophisticated, firms will need robust data governance, transparent audit trails, and clear communication from regulators about how alerts translate into actions. The balance between rapid intervention and fair process will be a focal point as these AI-enabled systems mature and begin to interact with real-world market dynamics.

As AI continues to permeate financial supervision, observers will watch how these technologies influence liquidity, price discovery, and market resilience. If the early tests hold, the FSS and its Korean counterparts could set a precedent for how AI-driven surveillance shapes regulatory practice across regions facing parallel challenges in crypto and traditional markets alike. The coming months will be telling as deployment advances, new capabilities come online, and regulators translate automated insights into concrete policy and enforcement steps.
