The Senate confirmed Kevin Warsh as Federal Reserve chair on Wednesday by a 54-45 vote, the closest confirmation margin in the modern era of the central bank. Warsh, 56, takes over from Jerome Powell, whose term as chair expires Friday. His first FOMC meeting is June 16-17. The circumstances of his arrival are not what the White House imagined when it nominated him.
Trump appointed Warsh in part because he had argued publicly that the Fed had room to cut rates. On Tuesday, U.S. CPI came in at 3.8% year-over-year, the highest since May 2023. On Wednesday, U.S. PPI came in at 6.0% year-over-year, the highest since December 2022, and nearly triple the consensus forecast on a monthly basis. By the time the Senate vote concluded, CME Group's FedWatch tool showed traders pricing a roughly 39% probability of at least one Fed rate hike by year-end 2026, up from near zero at the start of the year.
What Warsh Actually Inherits
The inflation data Warsh inherits has two components that matter differently for policy. The headline driver is energy: gasoline prices surged 28.4% year-over-year in the CPI release, a direct consequence of the Strait of Hormuz closure that began in late February. Energy goods accounted for roughly three-quarters of the PPI goods advance in April. This component is supply-side, identifiable in origin, and in principle self-correcting if the geopolitical situation resolves.
The more concerning element is what is happening outside energy. Core CPI, excluding food and energy, rose 0.4% month-over-month in April, above the 0.3% consensus and the highest monthly reading since January 2025. Services drove nearly 60% of the PPI advance. Shelter costs rose 0.6% in April after easing in prior months. These are not Strait of Hormuz numbers. They reflect a broader price environment that was already running above the Fed's 2% target before the Iran war began, and they complicate the narrative that inflation will simply retreat when the energy shock fades.
The chart above shows U.S. CPI and core CPI year-over-year from January 2024 through April 2026, with the Warsh confirmation date and the Iran war onset marked.
The headline CPI acceleration from 2.8% in February to 3.8% in April is almost entirely Iran-war-driven energy inflation. Core CPI, which strips out food and energy, rose more modestly from 2.6% to 2.8% over the same period, but its 0.4% monthly gain in April is the most important number for Warsh's first meeting calculus.

The BoC's Specific Problem With the Warsh Confirmation
The Bank of Canada's June 10 decision arrives five days before Warsh chairs his first FOMC meeting on June 16-17. That sequencing creates a specific analytical problem for Governor Macklem. The BoC held at 2.25% on April 29, signalling it saw roughly equal risks of needing to cut (if trade restrictions bite the economy) or hike (if energy inflation broadens). Markets before this week's data were pricing an 80% probability of no change on June 10, with only a 5% probability of a hike.
That calculus shifts meaningfully with Warsh at the Fed. The BoC's credibility depends in part on not being seen to diverge dramatically from U.S. monetary policy, particularly in an environment where a weaker CAD would itself import additional inflation through higher import prices. If Warsh's first meeting signals a hawkish tilt, a BoC cut in the same month becomes nearly impossible to defend publicly. The BoC is not the Fed's shadow, but the transmission mechanism from U.S. rate expectations to Canadian bond markets is real and fast.
The Canadian April CPI print, due May 19 from Statistics Canada, will arrive between now and the June 10 decision. The BoC projected April Canadian CPI at approximately 3%, reflecting the full pass-through of gasoline prices that were already surging in March. If the actual print comes in above that projection, the June 10 hold becomes even more firmly cemented. The conversation about a BoC hike, which was fringe in January, is no longer fringe.
What the Warsh Era Means for Canadian Rate Markets
Warsh is not an unknown quantity. During his first stint at the Fed from 2006 to 2011, he was a consistent dissenter against quantitative easing, arguing the balance sheet expansion had gone too far. He has since called for "regime change" at the central bank and proposed changes to how the Fed communicates. None of that necessarily translates to a hawkish rate path in 2026. His stated position has been that there is room to cut, and he has promised to exercise independent judgment rather than follow White House direction.
The analytical reality he faces is more constrained. At his first meeting, Warsh will have in front of him a 3.8% headline CPI, a 6.0% PPI, a core CPI that is re-accelerating, and a committee that already included three members at the April meeting who indicated their next move could as easily be a hike as a cut. Cutting rates into that data environment would be extraordinarily difficult to justify. Holding is the base case. The question Warsh's arrival adds to the Canadian portfolio equation is what happens to Government of Canada bond yields if U.S. rate hike probabilities continue to rise.
