The United States Senate confirmed Kevin Warsh as the 17th chair of the Federal Reserve on Wednesday in a 54-45 vote that fell almost entirely along party lines — the narrowest majority ever recorded for a Fed chairmanship confirmation. Warsh, 56, a former Fed governor during the 2008 financial crisis and ex-Morgan Stanley banker, will formally take office on Friday, succeeding Jerome Powell, whose eight-year tenure was marked by successive economic crises and a prolonged confrontation with the White House over the central bank's independence. Pennsylvania Democrat John Fetterman was the only senator to cross party lines, voting in favour of Trump's nominee.

The path to confirmation was far from straightforward. Republican Senator Thom Tillis of North Carolina had blocked the nomination for weeks while the Justice Department conducted an investigation into Powell over his Senate testimony about cost overruns at the Fed's Washington headquarters renovation. The probe was dropped in April, clearing the way for the vote. Federal prosecutor Jeanine Pirro has nonetheless warned the inquiry could be reopened if the Fed's inspector general finds evidence of misconduct. In an unusual move, Powell has said he will remain on the Fed's Board of Governors — retaining influence over interest rate decisions — until the internal investigation concludes. Only Marriner Eccles, in 1948, made an equivalent choice after leaving the chairmanship.

Warsh takes the helm at an exceptionally difficult moment for the independent agency. Inflation reached 3.8% in April, a three-year high, driven largely by a spike in energy prices following the closure of the Strait of Hormuz amid the US-Israel conflict with Iran. The Fed's rate-setting committee has kept its benchmark rate unchanged for three consecutive meetings, and last month saw the most dissenting votes within the committee in over three decades — a signal that Warsh may face internal resistance if he moves quickly to cut rates. Markets are currently pricing in no rate reductions for the remainder of the year.

The political backdrop adds further complexity. President Trump has repeatedly and publicly demanded interest rate cuts, reportedly joking — according to CNN — that he would sue Warsh if rates are not lowered. Senate Majority Leader John Thune praised Warsh as someone who understands both the broader macroeconomy and the concerns of ordinary working Americans. Critics, however, have raised sharp questions about his independence. Senator Elizabeth Warren, a Democrat from Massachusetts, called him a "sock puppet" for Trump during his confirmation hearing, and Democrats condemned his refusal to fully disclose the details of his personal wealth, estimated at over $100 million and including stakes in companies such as Polymarket and SpaceX. Warsh has pledged to divest all such holdings within 90 days of being sworn in.

For his part, Warsh told senators during his hearing that Trump "never once" asked him to commit to a specific interest rate decision and pledged to act as an independent actor. He has been a long-standing critic of the Fed's recent track record, particularly its slow response to the 2021–22 inflation surge, and has called for "regime change" at the institution — including fewer press conferences, reduced communications, and a smaller workforce. His first monetary policy meeting is scheduled for 16–17 June, when markets and governments worldwide will be watching closely for signals about the new Fed's direction.
