The Bank for International Settlements Innovation Hub published a technical white paper detailing Project Rio, a real-time market monitoring platform developed with central banks to support oversight of fast-paced electronic markets, particularly foreign exchange. The platform is designed to stream, process and visualise high-frequency market data to produce actionable insights on liquidity, trading activity and risks with latency below two seconds. Project Rio uses modern open-source technology and a modular, scalable architecture that separates data ingestion, processing, storage and visualisation to enable flexibility and adaptation to new markets and instruments. An intuitive dashboard, developed with central bank user feedback, is intended to integrate into existing workflows and help bridge machine-speed markets and human decision-making.
