When the Bank of Canada held at 2.25% on April 29, Governor Tiff Macklem articulated the dilemma with unusual candour: raising rates to slow energy-driven inflation could further weaken an already soft economy, while cutting to support growth risked pushing inflation persistently above target. The resolution of that dilemma depends on one variable above all others -- how long the Hormuz disruption lasts and what it does to oil prices over the coming months.
This morning's oil move is the first significant evidence that the disruption may resolve sooner than the BoC's April baseline assumed. WTI fell to $91.73, down more than 5%, after Trump declared the peace deal "largely negotiated" over the weekend. Brent fell to $98. The BoC's April 29 MPR projected Brent at approximately $90 in Q2, declining to $75 by mid-2027. A deal that reopens the Strait and confirms that trajectory would, on paper, validate the BoC's baseline -- and reduce, though not eliminate, the case for the October hike markets are currently pricing.
The problem is that the deal is not done. Secretary of State Rubio, speaking from New Delhi on Monday, called it "a work in progress." Iran's foreign ministry cited unresolved disagreements on the Strait's status. The oil market has moved on the probability of a deal, not the fact of one. The BoC will not move on probability either.
What the April CPI Data Tells the BoC
Statistics Canada reported April CPI at 2.8% year-over-year on May 19, up from 2.4% in March. The headline acceleration was almost entirely energy-driven: gasoline prices rose 28.6% year-over-year, and total energy inflation ran at 19.2%, the fastest since 2022. Excluding gasoline, April CPI rose 2.0% -- essentially at target.
This is the distinction Macklem flagged at the April 29 press conference. The BoC's concern is not what energy prices are doing to headline CPI -- that is expected, mechanical, and temporary if oil falls. The concern is whether energy-cost pass-through is beginning to show up in services and non-energy goods prices, producing the "broadening" that Macklem explicitly said would trigger a policy response.
TD Economics noted in its May 19 CPI commentary that services inflation actually cooled to 1.7% year-over-year in April, down from 2.6% in March. Core goods inflation picked up modestly to 1.6% from 0.9%. The broadening that would force the BoC's hand has not yet materialized. But shelter inflation is edging higher -- up to 1.8% year-over-year from 1.7% -- driven by utility costs rising 5.5% as energy prices pass through to electricity and fuel bills. That is the channel to watch through May and June.
The chart below shows Canada's CPI trajectory from February 2025 through April 2026, with the BoC's 2% target and control band marked, and the energy shock visible in the acceleration from February to April 2026.
Canada's CPI remained within the BoC's 1% to 3% control band throughout the period shown, but the April 2026 acceleration to 2.8% -- driven almost entirely by the energy shock from the Hormuz closure -- pushed the headline toward the upper half of the band for the first time since mid-2025. The March 4 closure is visible in the data with a one-month lag.
The Q1 GDP Picture and Why It Matters for June 10
Canada's Q1 2026 GDP is tracking approximately 1.7% annualized, according to RBC Economics, reversing the -0.6% contraction in Q4 2025. Statistics Canada's monthly data showed real output grew 0.1% in January and 0.2% in February, with a flash estimate for March pointing to essentially flat performance -- consistent with Q1 economy-wide expansion of approximately 0.4% on a quarterly basis.
The recovery is narrowly based and should not be mistaken for underlying strength. Household spending and government expenditure are the primary drivers. Residential investment remains soft as high borrowing costs and affordability constraints persist. Net exports are subtracting from headline growth as a surge in Q1 imports -- consistent with businesses stockpiling ahead of CUSMA uncertainty -- offsets export gains. And Canada's near-zero population growth in 2026 means the headline GDP figure understates the per-capita improvement but also limits the economy's structural capacity.
For the June 10 decision, the growth picture supports holding. The economy is growing but not robustly, and there is no case on growth grounds for hiking into the current momentum. The question is entirely on the inflation side: if today's oil decline holds and the peace deal hardens over the next two weeks, the April 29 BoC baseline -- Brent declining from $90 toward $75 by mid-2027 -- becomes more plausible, and the October hike markets are pricing becomes less certain.
Bank Earnings This Week as a Growth Signal
The macro picture gains additional texture this week from Big Six bank earnings. Scotiabank, BMO, and National Bank report Wednesday; CIBC, TD, and RBC report Thursday. The Q1 bank results in February were uniformly strong -- all six beat estimates, with wealth management and capital markets as primary drivers. The Q2 results covering the period through April 30 will be the first full-quarter read on how the energy price shock is affecting household credit quality.
The variable to watch is provisions for credit losses, the money banks set aside to cover sour loans. An increase in PCLs on the personal banking side would signal that elevated energy costs are beginning to stress Canadian household finances -- which is exactly the transmission mechanism the BoC is watching when it monitors whether energy inflation is "broadening." Strong earnings with stable PCLs would be a modestly hawkish signal for October. Rising PCLs alongside still-elevated inflation would restore the exact dilemma Macklem described on April 29.
