Circular CSSF 21/783 (outdated)

No description available.

AI Analysis

ESMA has withdrawn its MiFID II/MiFIR market data Guidelines because their subject matter has been transposed into Commission Delegated Regulation (EU) 2025/1156 on the obligation to make market data available on a reasonable commercial basis. As a result, CSSF Circular 21/783, which implemented those ESMA Guidelines in Luxembourg supervisory practice, will become formally outdated from 23 August 2026, requiring MiFID firms and trading venues to ensure their policies and commercial terms now fully align with the directly applicable RTS in the Delegated Regulation.
