Mr Peter Wilson > Katten > Chicago, United States > Lawyer Profile

CHICAGO, IL 60661-3693
United States

Work Department



The financial services industry is under constant scrutiny from regulators. Peter Wilson’s familiarity with the business of financial services firms, as well as the regulatory landscape, allows him to quickly assess clients’ potential legal exposure and identify the best solutions. He represents financial firms in regulatory inquiries, criminal investigations and high-stakes litigation, advising them on how to effectively interact with the government and to bring an efficient end to proceedings.

As a former attorney at the Consumer Financial Protection Bureau, Peter understands how regulators think and set priorities. He’s guided clients through probes by the Securities and Exchange Commission, the Commodity Futures Trading Commission, the Financial Industry Regulatory Authority and options and futures exchanges. With his ability to speak the language of the financial world and his fluency with its most esoteric products, he doesn’t need time to understand the issues his clients are facing.

Peter has represented clients accused of manipulating markets, defrauding investors and engaging in anticompetitive behavior. A significant part of his practice involves representing corporate boards and corporate monitors charged with investigating whether companies have installed sufficient controls to prevent misconduct.

His government experience, including his work enforcing the Dodd-Frank Act, positions him to craft arguments that resonate with regulators. In numerous situations, he has persuaded regulators to refrain from taking any action against his client, whether based on inadequate training given to an executive, unfairness concerns with applying an obscure regulation or other compelling reasons. Whatever the issue, Peter seeks to bring about speedy resolutions that allow businesses to keep operating as profitably as possible.
