Wetjen previously served as managing director and head of global public policy at the DTCC from 2011 – 2015.[2]

He joined the post-trade services utility in September 2015 after serving for four years as a commissioner at the Commodity Futures Trading Commission (CFTC). He stepped down from his role as commissioner in August 2015.[3]

In February of 2019 Wetjen was appointed chairman of the DTCC Deriv/SERV board of directors, replacing Larry Thompson, who retired in December 2018. Wetjen was appointed to the Deriv/SERV board in September 2018.


In May 2011, President Barack Obama nominated Wetjen to replace CFTC Commissioner Michael Dunn, who had served in the position since December of 2004.[4][5] He was sworn in as a commissioner on October 26, 2011.[6]

Upon Wetjen's confirmation in 2011, the Futures Industry Association (FIA) released a statement, saying that Wetjen's "commitment to a careful, measured and thoughtful process for consideration of regulatory matters is one that we can all endorse."[7]

He became acting chairman upon the end of Chairman Gary Gensler’s service in January 2014 [8] and remained acting chairman until the Senate confirmed Timothy Massad as the new chairman in June 2014. On Aug. 14, 2015 he announced his resignation from the CFTC, effective August 28, 2015.[9]

Wetjen was formerly a top aide to Senate Majority Leader Harry Reid (D., Nev.), beginning in 2004. Before that, he worked for Lionel Sawyer & Collins and specialized in regulatory issues affecting financial institutions. Early in his career, Wetjen focused on municipal finance transactions for the law firm Sherman & Howard.

He is also known for his work on the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which gave the CFTC new authority to oversee the over-the-counter derivatives market.
