The Federal Reserve left interest rates steady in what was almost certainly Jerome Powell's final meeting as its leader, but there were the most internal dissents at a Fed meeting in 34 years.The big picture: The surprising dissents show that Kevin Warsh, whose confirmation to lead the Fed is pending in the Senate, will face significant internal resistance to delivering the interest rate cuts that President Trump desires.Driving the news: The central bank's policy committee left its target interest rate in a range between 3.5% and 3.75% for the third straight meeting to start 2026 and made only small changes to its policy statement.Three reserve bank presidents — Beth Hammack (Cleveland), Neel Kashkari (Minneapolis) and Lorie Logan (Dallas) — dissented not against the rate decision, but because they "did not support inclusion of an easing bias in the statement at this time."Governor Stephen Miran also dissented, but in the other direction, favoring an interest rate cut.The four total dissents were the most there have been at a Fed policy meeting since October 1992.State of play: There has been simmering resistance among Fed officials, especially at the reserve banks, to signaling that further interest rate cuts are anticipated, given five consecutive years of above-target inflation.Now, it has burst out into the open, in Powell's final meeting at the helm.Powell's term concludes May 15, and Warsh's nomination to be his successor advanced through the Senate Banking Committee Wednesday morning. Warsh appears on track to be confirmed by the full Senate well before the next Fed meeting in mid-June.Between the lines: The clause in the policy statement the three dissenting reserve bank presidents object to is language, repeated from recent statements, that in considering "the extent and timing of additional adjustments" to rates, the Fed will carefully assess data, the outlook and balance of risks.·The phrase "additional adjustments" implies a continuation of the rate cuts the Fed enacted late last year.The hawkish officials don't want to rule out that the possibility that the next move might be a rate hike, in light of elevated inflation and solid growth.The intrigue: It is unclear whether Powell will resign entirely from the Fed's Board of Governors when Warsh starts or will continue to occupy his seat as one of seven governors. That term extends until early 2028.He is likely to be asked about his plans at a news conference that starts at 2:30pm ET.The bottom line: Powell has largely kept an often-fractious committee together through intense policy debates over the last eight years. But Warsh is set to inherit some deep divides.
