Commission Delegated Regulation (EU) 2025/1156 on regulatory technical standards for making market data available on a reasonable commercial basis

The European Commission adopted Delegated Regulation (EU) 2025/1156 to establish regulatory technical standards requiring market data providers, including trading venues, APAs, CTPs, and systematic internalisers, to make market data available on a reasonable commercial basis. The regulation mandates specific cost calculation methodologies, limits margins to operating profit expressed as a percentage of costs, and prohibits discriminatory fee structures and onerous contractual terms such as excessive audit burdens. It further requires that data be offered unbundled, on a per-client basis to prevent double billing, and sets a deferred application date to allow market participants time to revise agreements.
