As the countdown to Powell's departure begins, his most underrated "trump card" has emerged: adeptly navigating Capitol Hill to build a "firewall" protecting the Federal Reserve from political interference.
During his eight-year tenure, Federal Reserve Chair Powell has overseen multiple dramatic policy shifts. From swiftly cutting interest rates to near-zero levels and expanding asset purchases at an unprecedented pace following the COVID-19 pandemic's outbreak, to subsequently implementing the most aggressive interest rate hike cycle in forty years in response to soaring inflation, he has steered two major turns in U.S. monetary policy.
Throughout this process, Powell also made two significant adjustments to the Fed's policy framework while notably enhancing communication transparency, explaining policy intentions and action paths to the public more frequently than any of his predecessors. These measures constitute the most visible policy features of his term.
As his chairmanship concludes on Friday, external observers widely review his policy legacy. However, the capability that truly distinguishes him from his predecessors is not fully reflected in interest rate decisions or the policy framework.
Congressional relations have become the core "moat." Powell's continuous behind-the-scenes cultivation of relationships with Congress is considered one of his most prominent governance characteristics. In his view, Congress is not only a key channel for the Fed to accept oversight and accountability but also a crucial support force when political pressures intensify.
This orientation is closely linked to his professional background. As a native of Washington, D.C., Powell has worked in trading, served at the U.S. Treasury Department, and acted as a think tank analyst, contrasting sharply with predecessors like Yellen and Bernanke, who were known for their academic expertise.
Especially after tensions with then-President Trump early in his term, Powell placed greater emphasis on leveraging Congress to resist external interference, safeguarding the Fed's independence in interest rate decisions and economic judgments.
Thomas Drechsel, an assistant professor of economics at the University of Maryland, analyzed public schedule data and found that compared to Yellen and Bernanke, Powell's frequency of engagement with members of Congress was significantly higher. Particularly during the Trump administration, his meetings with members of both parties in the Senate and House of Representatives peaked.
Drechsel noted, "This interaction is systematic." He believes that, combined with Powell's career experience, such frequent communication has a certain inevitability; however, in the current political environment, its significance is particularly pronounced. "A reasonable explanation is that Powell actively engaged with Congress, perhaps precisely to protect the Federal Reserve."
Support and controversy coexist. This strategy has not eliminated all disputes. Ohio Republican Senator Bernie Moreno sharply criticized Powell during a 2025 Senate Banking Committee hearing. He stated that despite two previous meetings with Powell, it "did not change at all" his judgment that Powell is "highly politicized... and has caused significant harm to the Fed," a view shared by some Trump supporters.
Nevertheless, Powell has received support from certain members of Congress at critical moments. Drechsel's research data shows that he met with North Carolina Republican Senator Thom Tillis 11 times during his tenure. In a recent博弈 surrounding a now-withdrawn criminal investigation, it was Tillis who intervened to halt the advancement of nominee Kevin Warsh's confirmation when Powell was under pressure, until the government made concessions on related issues.
Warsh, who also has a legal background, is seen as having similar advantages in political communication. It is widely anticipated that he may continue Powell's practice of maintaining close interaction with Congress, especially as potential future changes in congressional control could affect the Fed's oversight structure, making this strategy an important balancing tool.
