Steven Terner Mnuchin, commonly known as Steve Mnuchin, is an American investment banker, film producer, and former government official who served as the 77th United States Secretary of the Treasury from 2017 to 2021 under President Donald Trump. Born into a prominent Jewish family in finance—his father, Robert Mnuchin, was a longtime Goldman Sachs executive—Mnuchin grew up on New York's Upper East Side. He graduated from Yale University in 1985, where he served as publisher of the Yale Daily News. Mnuchin began his career at Goldman Sachs in 1985, spending 17 years there as a partner and eventually becoming chief information officer, specializing in mortgage-backed securities trading. After leaving Goldman Sachs in 2002, he co-founded the hedge fund Dune Capital Management, serving as co-CEO and chairman, and diversified into the entertainment industry by producing and financing major films such as 'The Lego Movie' (2014), 'Mad Max: Fury Road' (2015), and 'Suicide Squad' (2016). In 2016, he joined Donald Trump's presidential campaign as national finance chairman, raising significant funds, and later contributed to the transition team. As Treasury Secretary, Mnuchin played a central role in implementing the Tax Cuts and Jobs Act of 2017, negotiating trade deals, and overseeing the economic response to the COVID-19 pandemic, including the CARES Act. His tenure was marked by controversies, including criticism for using military aircraft for personal trips costing taxpayers approximately $800,000 and allegations of conflicts of interest due to his finance background. Post-administration, Mnuchin has returned to private sector activities, including investments in cryptocurrency and continued involvement in film production. He remains a key figure in Republican finance circles and has been speculated as a potential candidate for political office, though he has not pursued it as of recent reports.
