General Index Limited (GX) is a data‑driven provider of regulated commodity price benchmarks and indices for global energy and related markets. Through its FCA‑authorised benchmark administration, the company produces transparent, methodology‑driven price assessments for crude oil, refined products, natural gas, LPG, and a range of energy transition and environmental markets such as hydrogen, biofuels, carbon, sustainable aviation fuel and Guarantees of Origin. Rather than relying on journalistic methods, General Index bases its benchmarks on large datasets of actual market activity, including more than 400,000 trades per month, which are processed using systematic methodologies to create robust, auditable indices used by producers, traders, refiners, utilities and end‑users for pricing, hedging and risk management. The company also offers delivery platforms such as GX Go that provide fast, accessible access to its pricing data, analytics and tools for customers that need real‑time or end‑of‑day commodity price information. Headquartered in London with additional offices in Houston, Krakow and Singapore, General Index positions itself as a transparent, customer‑centric alternative to traditional price reporting agencies in the global commodity and energy benchmark market.
