On September 18, the Commodity Futures Trading Commission amended its Rule 3.10(c) to exempt from registration as a futures commission merchant or introducing broker foreign firms that solicit or accept orders from U.S. persons for execution on U.S. markets. The exemption, which is limited to those foreign firms that have obtained relief from registration pursuant to CFTC Rule 30.10, codifies a series of no-action letters issued by CFTC staff over the last few years.
