19b-4 Rule

Definition

The 19b-4 Rule governs how self-regulatory organizations propose changes to their operational rules. It mandates that exchanges file these proposed rule alterations with the Securities and Exchange Commission (SEC) for public review. The SEC then evaluates these submissions to ensure adherence to federal securities laws, particularly concerning investor protection and market fairness. This regulatory procedure is especially pertinent to the introduction of new financial instruments, including those tied to digital assets.
