European Union regulators are focusing on pooled order books as they seek to enhance oversight under the Markets in Crypto-Assets (MiCA) framework. This move aims to address potential risks associated with the aggregation of orders from multiple trading platforms, which could impact market integrity and investor protection. The increased scrutiny is part of broader efforts to ensure comprehensive regulatory coverage of the rapidly evolving crypto market. The MiCA regulation, which is set to be implemented across EU member states, is designed to provide a unified regulatory approach to crypto-assets. By targeting pooled order books, regulators intend to prevent market manipulation and ensure transparency, thereby fostering a safer trading environment for investors.
