Citadel founder and CEO Ken Griffin has publicly criticised President Trump’s efforts to undermine the Federal Reserve, highlighting potential risks for investors and businesses in an opinion piece for the Wall Street Journal.

In the article, co-authored with University of Chicago economist Anil Kashyap, Griffin called the president’s attempts to influence monetary policy “a risky game” that could erode market confidence and drive higher long-term interest rates.

The duo warned that politicising the Fed could backfire, stoking inflation and increasing borrowing costs, ultimately creating headwinds for corporate profits. Griffin’s commentary is notable for being one of the few direct critiques of Trump from a major US corporate leader, and comes despite him having voted for the president in the past.

The debate over central bank independence is intensifying, with Treasury Secretary Scott Bessent proposing a narrower remit for the Fed to prevent “mission creep” while preserving its policy tools.
