Trump's attempt to remove a Fed governor has become the most expensive test of central bank independence in modern history.

The cost of President Donald Trump's bid to fire Federal Reserve Governor Lisa Cook has exceeded $1 million in legal and security fees, a legal filing shows, as the Supreme Court prepares to rule on a case that could reshape the central bank's independence.
"The case is potentially the most important legal case in the Fed's 113-year history," Fed Chair Jerome Powell said, underscoring the stakes of the constitutional standoff.
Cook, the first Black woman ever appointed to the Fed Board, has racked up more than $1 million fighting Trump's attempt to remove her, according to the filing. Trump sent a firing letter on Aug. 25, 2025, citing alleged mortgage fraud involving two properties she designated as primary residences in loan applications dating back to 2021. Cook has denied any wrongdoing, and no criminal charges have been filed against her. She acknowledged the designations were "improper" but maintains they were not unlawful.
The case, known as Trump v. Cook, threatens to upend a century of precedent shielding the Fed from political interference. If the Supreme Court upholds Trump's power to fire a Fed governor without cause, future presidents could pressure the central bank to align monetary policy with political cycles — potentially eroding the credibility that underpins the dollar's role as the world's reserve currency.
A $1 million price tag for a constitutional question
Cook was sworn in on May 23, 2022, after being appointed by President Joe Biden. Her term is set to run until 2038. She did not go quietly after receiving the firing letter, instead pursuing legal action to block her dismissal. The case escalated to the Supreme Court, where oral arguments were heard on Jan. 21, 2026. A ruling is expected imminently.
The legal and security costs disclosed in the filing include fees for Cook's legal team and additional security measures she has required since the firing attempt, reflecting the personal toll of the standoff. No criminal charges have been filed against Cook in connection with the mortgage allegations.
A pattern of pressure on the Fed
Trump's attempt to remove Cook is part of a broader campaign against the central bank's independence that has spanned his return to power. During his first term, Trump appointed Powell as Fed chair but quickly turned on him, writing on social media in August 2019: "My only question is, who is our bigger enemy, Jay Powell or Chairman Xi?" He later accused the Fed board of having "no 'guts,' no sense, no vision!" for not matching negative interest rates used in Europe and Japan.
After returning to the White House, Trump escalated from rhetoric to action. He ordered a Department of Justice investigation into whether Powell had lied to Congress about cost overruns in a long-running renovation project at the Fed's Washington headquarters. He also attempted to fire Biden appointee Cook based on the mortgage fraud allegations — a move that has been put on hold while the Supreme Court considers whether the attempted firing was justified under the law.
The current fed funds rate stands at 4.25 percent to 4.50 percent, unchanged since the 25-basis-point cut in December 2024. Overnight index swap markets price a 58 percent probability of a hold at the next meeting in July, according to CME FedWatch data.
What a ruling against Cook would mean
A Supreme Court decision allowing Trump to fire Cook without cause would mark the most significant legal shift in the Fed's governance since the Banking Act of 1935 established the current structure of the Board of Governors. That law gave governors 14-year terms and removed the Treasury secretary from the board, creating the institutional firewall that has allowed the Fed to set interest rates without regard to electoral cycles.
If the court sides with Trump, the immediate impact would be felt in bond markets, where the term premium on long-dated Treasuries could rise as investors price in a higher risk of political interference in monetary policy. The last time the Fed's independence was seriously questioned — during the Nixon administration's pressure on then-Chair Arthur Burns to keep rates low ahead of the 1972 election — inflation averaged 6.2 percent over the following two years, compared with the current 3.8 percent annual CPI reading.
The broader implication extends beyond Cook. If the president can fire a Fed governor at will, the central bank's ability to make unpopular decisions — raising rates to cool inflation even when it hurts the incumbent party — would be compromised. That dynamic could force the Fed to lean hawkish in its communications to compensate for the perceived loss of independence, effectively tightening financial conditions without moving rates.
