So here's where we are: the Justice Department is investigating Jerome Powell, the Federal Reserve chairman is crying foul about political interference, and Kevin Hassett—Trump loyalist and senior White House adviser—is telling everyone to calm down because this is really just about construction costs.

Hassett went on CNBC Monday and offered a narrative that directly contradicts Powell's. According to him, the DOJ probe has nothing to do with monetary policy or political revenge. Instead, it's about "dramatic cost overruns" on the Fed's $2.5 billion renovation project involving two office buildings.

"I don't think rate stance had anything to do with events," Hassett said, essentially swatting away Powell's accusation that the investigation is designed to intimidate the Fed into cutting rates faster.

Hassett, who serves as Director of the National Economic Council, went further. He suggested that the "big cost overruns look inconsistent with testimony," implying that Powell may have misled Congress during his June appearance before the Senate Banking Committee.

Powell Says This Is About Independence

Just one day before Hassett's appearance, Powell released a video statement revealing that the Fed had been served with subpoenas and faced threats of criminal charges related to his congressional testimony. He didn't mince words.

"This is about whether the Fed will be able to continue to set interest rates based on evidence and economic conditions—or whether instead monetary policy will be directed by political pressure or intimidation," Powell said. He called the DOJ move a "pretext" for undermining the Fed's independence.

For months, Hassett has hovered at the margins of this story—an influential adviser with Trump's ear who has consistently argued that the Fed should cut rates more aggressively. Now, with Powell under fire, Hassett is stepping into the center of the conversation.

Betting Markets See a Succession Fight Underway

Traders aren't waiting around to see how this plays out. On Polymarket, Hassett's odds of being nominated as the next Fed chair jumped to 43%, making him the new front-runner ahead of Kevin Warsh.

Powell's term doesn't officially expire until May 14, 2026, but markets are betting Trump might not wait that long. The odds of Trump suing Powell by March 31 rose to 27%. Even more striking: there's now a 70% chance that Powell gets removed not just as chair, but from the Fed board entirely.

What you're watching here are two competing visions of central banking. Powell has built his tenure around data dependence and institutional credibility, arguing that the Fed's independence is what gives its decisions weight. Hassett, on the other hand, has repeatedly said rates are too high and that the Fed risks strangling economic growth by being too cautious about easing.

Yardeni Warns: Markets Are Already Reacting

Veteran market strategist Ed Yardeni appeared on CNBC and didn't sugarcoat his view. "Clearly the market doesn't like it," he said, pointing to gold hitting all-time record highs as evidence that investors are spooked.

Yardeni said he expected some turbulence around the Fed chair selection process, but not this. "I did think we were going to have some turbulence related to the Fed, but I thought it was going to be when Trump actually picked his new Fed chair," Yardeni explained. "I didn't expect that he'd actually go through with trying to investigate Powell."

He also flagged the bond market as the next flashpoint. "It looks like this issue with the Fed could already cause the bond vigilantes to act up," Yardeni warned.

On monetary policy, he raised another concern: "If the Fed just continues to lower rates… because of pressure from the administration, that could create a melt-up," with liquidity flooding into markets rather than supporting the real economy.

Legal Experts: Investigation Is Easy, Conviction Is Hard

Jonathan Kanter, former assistant attorney general and now a law professor, offered perspective on what this investigation actually means. Speaking on CNBC, he noted that the referral appears tied to potential perjury before Congress.

"The bar for opening up a criminal investigation is very low," Kanter said. "The bar for convicting somebody for a crime is very high."

He described the path from investigation to conviction as steep and uncertain. "What it would take to go from, you know, a concern that perhaps he misrepresented something before Congress to actually a conviction is a very long road," Kanter explained.

Perjury cases based solely on testimony are rare and difficult to prove. "An investigation, lying before Congress, it's hard, it's unusual, and it's going to be very difficult," Kanter said.

Markets Move Fast: Gold Soars, Dollar Falls, Yields Rise

Investors didn't wait for clarity before repositioning. S&P 500 futures dropped 0.4%, while Nasdaq 100 futures fell 0.6%.

The dollar index tumbled 0.5%, heading toward its worst session since before Christmas. Longer-dated Treasury yields climbed, with the 30-year rate jumping 4 basis points to 4.86%.

Gold—as tracked by the SPDR Gold Trust (GLD)—surged 2.7% to $4,620, hitting a fresh record high. Silver rallied even harder, climbing 7% to over $84 per ounce.

For traders, the message is clear: Hassett isn't just commenting on the Powell investigation. He's offering an alternative narrative, and markets are pricing in the possibility that he's the next Fed chair. The succession fight isn't theoretical anymore—it's already showing up in the price action.
