By Barry R. Temkin and Michelle Atlas* Following the ﬁnancial crisis of 2008, the role of Chief Compliance Ofﬁcer for ﬁnancial institutions has been redeﬁned, most notably by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. A review of recent regulatory enforcement actions reveals a trend of increased scrutiny of Chief Compliance Ofﬁcers of futures commission merchants, investment advisors, broker-dealers, and other ﬁnancial services entities. It is difﬁcult to predict how much the regulatory environment will relax under the Trump Administration. Donald Trump has announced an intention to repeal Dodd-Frank, as well as other signature Obama initiatives. Moreover, Mary Jo White, the aggressive, proenforcement chair of the Securities and Exchange Commission, has departed, leaving multiple vacancies on the commission.
