John Avery discusses opportunities in big data and graph analytics for financial services. Big data involves storing, processing, and analyzing large amounts of structured and unstructured data across distributed systems. It can help financial firms reduce the effort to analyze more data and enable new types of analyses. Graph analytics uses relationships in data to power applications in areas like risk management, trading, and regulatory compliance. Firms should explore applying these technologies to problems like counterparty risk analysis, market surveillance, and systemic risk oversight.
