Citadel CEO Ken Griffin has delivered a blunt warning to Donald Trump: stop meddling with the Federal Reserve or risk igniting a national debt crisis. Writing in a Wall Street Journal op-ed with University of Chicago professor Anil Kashyap, Griffin argued that political interference could erode trust in U.S. financial stability, sending borrowing costs sharply higher.
The remarks come as Trump has renewed his attacks on Fed Chair Jerome Powell, signaling that he would seek new leadership if re-elected. Griffin and Kashyap cautioned that such moves could weaken the Fed’s independence, spark fears of runaway inflation, and push investors to demand higher interest rates on U.S. debt.
A Warning on Market Trust
“Borrowing costs reflect trust. Undermine that trust, and the consequences are severe,” Griffin wrote. He emphasized that credibility at the Fed is not just an institutional matter, but a linchpin of global investor confidence in U.S. bonds and the dollar.
Any signal that the Fed is being politically controlled could lead to a sharp sell-off in Treasuries, forcing Washington to pay far more to finance its obligations. With debt already at record highs, Griffin warned that the country could slide into a debt spiral that undermines its economic future.
Trump’s Pressure on the Fed
Trump has long criticized Powell, whom he appointed in 2018, for being too slow to cut rates. More recently, he has floated names like former adviser Kevin Hassett as possible replacements. While presidents have authority over Fed appointments, Griffin argued that open campaigns to oust officials or dictate policy cross a line that markets view as dangerous.
“Trump’s pressure on the Fed isn’t just rhetoric,” Griffin noted. “It risks creating a perception that America’s central bank no longer operates independently, and that perception alone could raise interest costs.”
Wall Street Leaders Close Ranks
Griffin is not alone. A coalition of business leaders, including executives from JPMorgan Chase, Goldman Sachs, Citigroup, and Bank of America, have echoed concerns that Fed independence is non-negotiable.
Jamie Dimon of JPMorgan said that weakening the Fed would damage the dollar’s reserve currency status. Goldman’s David Solomon warned that political interference could reduce foreign demand for U.S. assets, increasing volatility across global markets.
Debt, Inflation, and Global Stakes
The warning comes as U.S. debt levels remain near historic highs, and inflationary pressures linger. Rising bond yields already reflect investor caution, and any new doubts about the Fed could amplify volatility.
Griffin emphasized that the stakes are geopolitical as well as economic. A compromised Fed could embolden rivals like China to push alternatives to the dollar, challenging America’s dominance in global finance.
What It Means Going Forward
For now, Powell remains in charge and the Fed continues to operate independently. But Griffin’s message highlights a growing unease among business leaders about Trump’s approach. The risk, he argued, is that political interference could destabilize bond markets, raise government borrowing costs, and ultimately lead to a U.S. debt crisis.
“The path forward requires discipline, not interference,” Griffin concluded.
