Ultumus has announced a new collaboration with BMLL to integrate its ETF and index data into BMLL’s analytics platforms, enhancing data access and trading insights for market participants globally. The partnership brings together Ultumus’ reference and index datasets with BMLL’s harmonised, historical Level 1, 2, and 3 market data and analytics, supporting a wide range of ETF use cases across the investment ecosystem.
The partnership allows ETF issuers, banks, brokers, asset managers, exchanges, and regulators to access Ultumus’ ETF reference data through BMLL’s platforms, including the BMLL Data Lab and BMLL Vantage. These tools provide Python-based research environments and visual analytics on market microstructure, with ETF data available before market open each day across multiple regions.
“Real benefits for ETF issuers and the broader trading ecosystem”
A key focus of the collaboration is the impact of Ultumus’ Portfolio Composition File (PCF) service on ETF trading efficiency. By combining PCF data with BMLL’s high-resolution analytics, a leading European ETF issuer was able to identify a 16% reduction in spread threshold breaches and a 12% improvement in trading performance.
Bernie Thurston, CEO of Ultumus, commented, “At Ultumus, our focus is on delivering measurable value through data innovation. By utilising BMLL’s granular Level 3 data and analytics, we’re able to quantify how accurate, timely fund data improves trading outcomes and market efficiency for clients using Ultumus’ Portfolio Composition File (PCF) service. This collaboration underscores our commitment to innovation and to delivering real benefits for ETF issuers and the broader trading ecosystem.”
The integration enables BMLL’s global user base to access issuer-published ETF metrics alongside historical market data, expanding its data coverage and functionality. With coverage spanning over 100 global trading venues and the full MSCI World Index, BMLL’s infrastructure now provides deeper insight into ETF liquidity trends and performance benchmarks.
Paul Humphrey, CEO of BMLL, said, “Adding ETF data from Ultumus is part of BMLL’s ongoing strategy to broaden our content and data coverage globally, which already includes historical market data from over 100 trading venues and our equities offering covering 100% of the MSCI World Index. We’re very excited to collaborate with Ultumus as our global customer base is now able to use these combined data sets to deepen their understanding of ETF liquidity dynamics, how these shift over time, and gain insights that will help them differentiate themselves in a competitive landscape.”
The companies said the collaboration is already enabling ETF issuers to enhance market transparency and improve pricing precision. By linking PCF accuracy to market impact, the combined offering is positioned to support upcoming ETF launches and strengthen the feedback loop between data quality and execution outcomes.
