The Central Bank of Russia has published a draft ordinance to update how brokers, trustees, dealers, and depositories are classified as large, medium-sized, or small professional securities market participants. The proposal would replace thresholds that no longer reflect current market conditions and use a firm’s transaction volumes and the type of operations it conducts to determine its category, which would then drive the regulatory requirements and intensity of supervision that apply. The review follows a marked expansion in the market between 2020 and 2025, including growth in client numbers, transaction volumes, and assets held in client accounts. Under the proposed approach, revised thresholds would reduce excessive regulatory and supervisory pressure on firms with a small market share that do not present significant risks.
