Background
LSEG (London Stock Exchange Group) is a British financial markets infrastructure company headquartered in London, with revenues of approximately £8 billion. It operates the London Stock Exchange, the Refinitiv financial data and analytics platform (acquired from Thomson Reuters for $27 billion in 2021), the FTSE Russell index business, and LCH, one of the world's largest central clearing houses. LSEG ranks alongside Intercontinental Exchange and CME Group as a top-tier global market infrastructure provider.
Refinitiv's Eikon terminal and Workspace platform supply real-time pricing, news, and commodity data to financial institutions worldwide. Refinitiv's vessel-tracking intelligence — sourced from AIS feeds and commercial port data — is a component of the broader commodity and energy analytics suite used by oil traders, shipping Banks, and sanctions compliance teams alongside specialist platforms such as Kpler and MarineTraffic.
In the 2026 Iran blockade, LSEG's tanker-tracking data was cited as one of three independent sources confirming the transit of US-sanctioned Chinese tankers Rich Starry and Murlikishan through the Strait of Hormuz on 13-14 April, on the first day of CENTCOM enforcement. The 86% single-day drop in legitimate Hormuz traffic on 14 April was visible across all three platforms.
