Typical. This is the same bozo government agency that allowed the CME/CBOT merger without concern for monopoly pricing....and less competition. They just keep trying to justify their existence (and salaries !).
The CFTC has as much a voice in two publicly traded exchanges merging as the FDIC has a say in two banks hooking up. That is none. Why should they? Ever hear of the FTC? These issues are their domain. If you have a beef with Chicago's pricing then either a. lease a membership or b. trade Eurex.
