Title 15 › Chapter 2B— SECURITIES EXCHANGES › § 78dd

Last updated Apr 3, 2026|Official source

Summary

Brokers and dealers must not use the mail or interstate communications to make trades on a foreign exchange in securities of companies tied to the United States if those trades break rules the Securities and Exchange Commission (SEC) creates to protect investors or to stop people from evading U.S. securities laws. The rules in this chapter don’t apply to someone who only does securities business entirely outside the United States, unless they violate SEC rules written to prevent evasion. Rules added by the Wall Street Transparency and Accountability Act of 2010 do not apply to people who trade security-based swaps only outside the United States, unless they break SEC anti-evasion rules. That limit does not reduce the SEC’s authority under the law as it existed before July 21, 2010.
