Statistics Canada confirmed August CPI held at 3.0% year over year, unchanged from July. Core measures excluding gasoline came in at 2.4%, a full point above the Bank of Canada's 2% target. The Bank held its policy rate at 2.25% on September 2 for a seventh consecutive decision. Twenty-four hours from now, the U.S. Federal Reserve is expected to move the opposite direction, on a driver both countries share.
Two Central Banks, One Oil Shock, Two Responses
The mechanism connecting these decisions is the same Strait of Hormuz closure and Saudi pipeline strike driving WTI crude up 24% since late August. In Canada, that shock shows up as gasoline inflation of 22.8% year over year, decelerating slightly from July's 25.7% but still the single largest contributor to the headline number. CIBC Economics reads the Canadian core measures as evidence the energy shock has not broadened into the rest of the basket, comfort the Bank cited in its September 2 hold.
The Fed is reading the same oil price through a different transmission. Markets are pricing roughly 87 to 88% odds the Federal Open Market Committee raises its target range at Wednesday's meeting, a reversal of the easing cycle that took the Fed from 4.00 to 4.25% in September 2025 down to its current 3.50 to 3.75% range by December. A hike this week would be the first increase since the current tightening cycle began, driven by the same oil-price pass-through into U.S. headline inflation that Canada is managing with a hold instead.
Why the Transmission Differs
The Bank of Canada's own language explains the asymmetry. Its September 2 statement flagged that new U.S. tariffs and Canadian counter-measures, following the breakdown of trade talks, have introduced growth risk the Fed does not carry in the same form: a domestic economy facing both an inflationary oil shock and a contractionary trade shock at once. Governor Macklem's Bank has chosen to hold rather than tighten into that second risk, with analysts noting the Bank may eventually need to cut if the trade war weighs further on consumer spending and employment.
The Fed faces the oil shock without the same trade-war drag on its own economy, leaving inflation control as the dominant consideration. That is the entire explanation for why two central banks looking at the identical crude oil chart are about to move in opposite directions within the same week.

What the Divergence Means for the Five-Year
Government of Canada bond yields take their cue from the Bank's own rate path more than from the Fed's, so a U.S. hike this week does not mechanically move Canadian yields the way a BoC decision would. But a Fed hike into an oil shock the Bank of Canada is holding through widens the policy gap between the two countries, a gap that has already been pressuring the Canadian dollar toward its recent one-month low near 1.39 per U.S. dollar. A wider rate gap typically means more of that currency pressure, not less, heading into the Bank's October 28 decision.
