January 11, 2026, will be remembered as a watershed date in the history of the U.S. Federal Reserve. That evening, Jerome Powell released a two-minute video unprecedented in the 112-year history of the world's most powerful central bank. The Fed Chairman publicly announced that he was under criminal investigation by the Department of Justice, accusing the Trump administration of using the law as a political pressure tool to bend monetary policy to the White House's wishes.
For us investors operating in American markets, this institutional clash represents much more than a political skirmish. At stake is the very independence of the Federal Reserve, the cornerstone that for decades has ensured stability in financial markets and the credibility of the dollar as the world's reserve currency.
The Pretext of Restructuring
Formally, the DOJ investigation concerns Powell's testimony to the Senate in June 2025 regarding the renovation of the Fed's Washington headquarters. The project, which began with an estimated budget of $1.9 billion, has ballooned to $2.5 billion, drawing ire from the Trump administration, which accuses Powell of lying to Congress about the nature of the work.
Federal prosecutor Jeanine Pirro accuses the Fed of installing what it considers luxurious and unnecessary features: special elevators, decorative fountains, and rooftop garden terraces. Essentially, she alleges that Powell committed perjury, a criminal offense, by downplaying the expense to senators.
Powell, however, has no doubts: the restructuring is merely a pretext. In his video, he used precisely this word, "pretexts," to define the Justice Department's accusations. The real reason for the investigation, according to the Fed chairman, is different: to force him to lower interest rates in accordance with White House dictates rather than independent economic analysis.
A War Declared Months Ago
To fully understand this crisis, we need to revisit the tense months that preceded it. Donald Trump has never made a secret of his aversion to Powell, despite having appointed him to lead the Fed during his first term in 2017. The attacks have intensified throughout 2025, with the president using increasingly aggressive language toward the central banker.
The most emblematic moment of this tension materialized last July, when Trump personally visited the Fed's renovation construction site. In front of the cameras, the president challenged Powell's budget numbers, citing a figure of $3.1 billion that included a building completed five years earlier. Powell, visibly perplexed, corrected the president live on air, creating a moment of institutional embarrassment rarely seen in American history.
The Lisa Cook Case and the Assault on the Fed
The Powell investigation is not an isolated incident. It is part of a broader strategy by the Trump administration to seize control of the Federal Reserve. In August 2025, the president attempted to fire Lisa Cook, Biden's nominee for the Fed's governorship, accusing her of mortgage fraud for declaring two different properties as her "primary residence" in 2021, before even joining the central bank's board.
Cook has always denied any wrongdoing, and bank documents obtained by the press appear to contradict the accusations. The case ended up before the Supreme Court, which in October 2025 decided to keep Cook in his post pending a hearing scheduled for January 21, 2026. This ruling temporarily halted Trump's assault on the Fed's independence, but it leaves open the fundamental question: can a president remove central bank governors at will?
The Federal Reserve Act provides that governors can be removed only "for cause," meaning for just cause related to misconduct while in office. Trump maintains that Cook's alleged fraud, even if it occurred before his appointment, constitutes just cause. If the Supreme Court were to rule in his favor, it would set a precedent that would allow presidents to shape the Fed at will, compromising the independence that markets take for granted.
The Reaction of Markets and Politics
The Monday following Powell's announcement, markets reacted nervously. The Dow Jones opened down more than 400 points, a clear sign of investors' fears of the erosion of the Fed's independence. Volatility then eased throughout the day, but the message was unmistakable: Wall Street does not welcome political interference in monetary policy decisions.
The bipartisan reaction in Congress was also significant. While criticism from Democrats was to be expected, the stance taken by some Republican senators was more surprising. Thom Tillis of North Carolina declared he would oppose the confirmation of any Fed nominee, including the next chairman, until the legal issue is resolved. Kevin Cramer, while calling Powell a "bad Fed chairman," also clarified that he does not believe he is a criminal.
| Actor | Position |
|---|---|
| Trump | "I don't know anything about the investigation, but Powell is not good at the Fed and he's not good at building buildings." |
| Senator Tillis (R) | It will block all Fed appointments until the case is resolved. |
| Senator Cramer (R) | "Bad Fed Chairman, but not a criminal" |
| Former Fed Chairmen | Joint declaration signed against "unprecedented attack" on independence |
Particularly significant was the joint statement signed by all surviving former Federal Reserve chairmen. Greenspan, Bernanke, and Yellen called the DOJ subpoenas an unprecedented attempt to use judicial attacks to undermine the central bank's independence, comparing the situation to that of emerging markets with weak institutions.
What This Means for Investors
For those operating in American markets, this institutional clash requires serious reflection on systemic risks. The independence of the Federal Reserve is not an abstract concept: it is the foundation upon which the credibility of American monetary policy rests, and consequently, the stability of the dollar and global financial markets.
In the short term, we should expect volatility related to developments in the matter. The Supreme Court hearing on the Cook case on January 21st represents the next crucial event. A ruling favorable to Trump would open up worrying scenarios for the Fed's autonomy, while a confirmation of existing protections would offer markets temporary reassurance.
Powell's term expires in May 2026, and Trump has already announced his choice of successor. If the new Fed chairman is perceived as subordinate to the White House, markets could price in an additional risk premium on US Treasuries and the dollar. International investors could begin diversifying their reserves, with long-term implications for the dominance of US assets in global portfolios.
A Look to the Future
Jerome Powell closed his video with words that sound like a manifesto of institutional resistance. He recalled having served under four administrations, Republican and Democratic, always carrying out his duties without fear or political favoritism. He concluded by stating that he will continue to do the job for which the Senate confirmed him, with integrity and commitment to the American people.
These are important words, revealing Powell's determination not to give in to pressure. But they also reveal the seriousness of the situation. Never before has a Fed chair had to publicly defend his independence from such direct attacks from the executive branch.
For us investors, the lesson is clear: America's institutional architecture, taken for granted for decades, is under pressure. This doesn't mean it will collapse, but it does mean we must incorporate into our risk models the possibility of structural changes that until recently seemed unthinkable. The independent Fed we've always known may not be the one we'll have tomorrow. And this, however the clash between Powell and Trump ends, is already a momentous shift in itself.
