Federal prosecutors reportedly have opened a criminal investigation into whether Federal Reserve Chair Jerome Powell lied to Congress about the scope of the central bank’s renovation of its Washington, D.C. headquarters. The investigation, approved by a longtime ally of President Trump, “marks a critical test of central bank independence in the U.S. that goes well beyond a technical dispute over a building renovation,” says Virginia Tech economist David Bieri.

Since the 1951 Treasury–Fed Accord, the Fed’s independence has rested on more than law. It has depended on operational autonomy, financial self-funding, and — crucially — norms that protect central bankers from coercion by other branches of government. “Those norms are now being stress-tested,” says Bieri.

He sees central bank independence complex concept with at least three dimensions: 

  • Legal independence (what the statute says)

  • Operational independence (who controls interest rates and balance-sheet tools)

  • De facto independence (whether policymakers can act without intimidation)

While the subpoenas don’t change the letter of the law, “they directly pressure the Fed’s de facto and personal independence — precisely the channels through which modern democracies protect monetary policy from short-term political leverage,” says Bieri. That distinction matters: once policymakers face credible legal or personal retaliation tied to official testimony or policy outcomes, independence survives on paper but erodes in practice.

Unlike the European Central Bank, the Fed’s independence is not constitutionally entrenched, meaning its sovereignty is ultimately statutory and norm-based. Bieri fears that undermining those norms risks pushing the US toward the kind of politicized monetary governance seen in countries where inflation credibility has repeatedly collapsed, from Venezuela to Hungary.

“This episode is therefore not about transparency or oversight — which already exist through congressional testimony and reporting — but about where democratic accountability ends and political interference begins,” he says.
