The Commodity Futures Trading Commission named Marc H. Sielski as the agency’s executive director on Monday, succeeding John Einstman, who had served in the role on an acting basis since October 2025.
Sielski, based in Washington, will oversee the Commission’s administrative operations with a mandate focused on modernization, workforce effectiveness, and fiscal stewardship of public resources. In practice, the executive director runs the CFTC’s Division of Administration, which covers budget formulation, procurement, HR, IT infrastructure, business continuity, and security operations.
“I look forward to supporting the Commission by strengthening core administrative functions, enabling a high-performing workforce, and modernizing how we deliver services across the agency in a fiscally responsible manner,” Sielski said. “I am committed to building durable operating rhythms, strong internal controls, and a culture of continuous improvement to enhance operational excellence and help the CFTC deliver on its priorities.”
Chairman Selig said Sielski brings “decades of experience in financial services and management consulting, with a strong track record of improving organizational effectiveness, operational excellence, and enterprise transformation.”
Sielski’s background spans enterprise transformation, governance, procurement, finance, HR coordination, and technology. He holds a B.B.A. in Finance and Investments from Baruch College.
The move from an acting arrangement to a permanent appointment comes as the CFTC moves to upgrade internal operations in response to what the chairman called “rapidly evolving markets.” Einstman will remain with the Commission in a new, unspecified role.
