Gary Gensler — regulator and, yes, Goldman alum — has distinguished himself in Washington. As CFTC Chairman, he’s fought to impose stricter rules on OTC derivatives and recently proposed rules that would cut the leverage currency traders are allowed to deploy from 100:1 to 10:1. Lest we all forget how dangerous leverage can be when traders misuse it, there’s LTCM to serve as exhibit A. In a clear sign that Gensler is fighting the good fight, traders are screaming about the proposed rule. Fantastic.
