The European Securities and Markets Authority (ESMA) is an independent EU authority that works to safeguard the stability of the European Union's financial system by enhancing investor protection and promoting stable and orderly financial markets. ESMA achieves this by regulating the securities and markets industry, ensuring transparency and efficiency, and reducing systemic risk. It also contributes to the single rulebook in the European Union by promoting consistent and harmonized regulation and supervision across member states. ESMA works closely with national competent authorities and other EU institutions to develop and enforce regulations, standards, and best practices for the securities and markets industry. Through its work, ESMA aims to promote a level playing field and ensure the integrity and transparency of the EU's financial markets.
