Abstract

This paper introduces a Large Language Model (LLM)-based multi-agent framework designed to enhance anomaly detection within financial market data, tackling the longstanding challenge of manually verifying system-generated anomaly alerts. The framework harnesses a collaborative network of AI agents, each specialised in distinct functions including data conversion, expert analysis via web research, institutional knowledge utilization or cross-checking and report consolidation and management roles. By coordinating these agents towards a common objective, the framework provides a comprehensive and automated approach for validating and interpreting financial data anomalies. I analyse the S&P 500 index to demonstrate the framework’s proficiency in enhancing the efficiency, accuracy and reduction of human intervention in financial market monitoring. The integration of AI’s autonomous functionalities with established analytical methods not only underscores the framework’s effectiveness in anomaly detection but also signals its broader applicability in supporting financial market monitoring.
