What it is
A broker-dealer is a financial services firm that operates in two capacities: as a "broker" and as a "dealer." As a broker, the firm executes trades on behalf of its clients, charging commissions for this service. As a dealer, the firm trades securities for its own account, acting as a principal in transactions and profiting from the spread between buying and selling prices. Broker-dealers are typically registered with and regulated by the Securities and Exchange Commission (SEC) and FINRA (Financial Industry Regulatory Authority).
In the context of digital assets, the question of whether a firm acting as an exchange or platform is a broker-dealer depends on whether the digital assets it facilitates are deemed "securities." If crypto assets are classified as securities, then platforms trading them must register as broker-dealers or operate under specific exemptions. This classification issue is central to regulatory debates, as unregistered broker-dealer activity can lead to enforcement actions, impacting platforms and the availability of certain tokens for retail investors.
Why it matters
Understanding the broker-dealer concept helps you grasp why crypto exchanges face regulatory challenges and potential enforcement actions if they trade digital assets deemed securities without proper registration.
