Canada's April CPI printed at 2.8% year over year on Tuesday, above March's 2.4% and below the consensus forecast of 3.1%. The headline number was driven almost entirely by energy: gasoline was up 28.6% year over year, the largest year-over-year gap in the data series. Excluding gasoline, the CPI rose a more modest 2.0% year over year, below March's comparable ex-gasoline reading. Energy as a whole was 19.2% higher than a year ago, the fastest pace since 2022.
So far, so expected. The more analytically consequential numbers were the core measures. CPI-trim, the Bank of Canada's preferred measure that strips out the most extreme price movements each month, fell to 2.0% in April. CPI-median fell to 2.1%. Both are now at five-year lows. The three-month annualized rates of both measures are at or below 2%. If those numbers were the only ones on the table, the June 10 conversation would be straightforward: core is where the Bank wants it, hold the rate.
Why the BoC Cannot Simply Look Through This
Governor Macklem's April 29 statement introduced a condition that complicates the look-through argument. The Bank agreed to look through the war's immediate impact on inflation, Macklem said, "but if energy prices stay high, we will not let their effects become persistent inflation." That framing creates an observable tripwire: if the energy shock persists long enough that inflation expectations begin to shift, the Bank will act regardless of what core measures are doing.
The chart above traces the divergence between headline CPI and core measures since the Hormuz closure began in March, alongside the rolling twelve-month history that provides context for how unusual the current split is. The gap between headline CPI at 2.8% and CPI-trim at 2.0% is now 80 basis points, the widest since the immediate post-pandemic reopening period in 2022.
Headline CPI (red) accelerated sharply after the Hormuz closure in March, while CPI-trim (grey dashed) and CPI-median (light grey dashed) continued their downward trajectory, falling to five-year lows in April. The 80-basis-point gap between headline and core is the widest since 2022 and reflects a supply-driven shock not yet transmitting into underlying price pressures.
The Bank's framework is built to distinguish between supply shocks, which should be looked through, and demand-driven or broad-based price increases, which require a policy response. The April data supports the look-through case on its face. But Macklem's conditional language was not a blank cheque. The condition is persistence. Energy above $100 per barrel for eleven weeks and counting is already testing the time horizon the Bank originally had in mind.
The June 10 Decision in Context
Bond markets as of this week price near-zero probability of a rate cut at the June 10 meeting, and approximately 1% probability of a hike. The base case embedded in current market pricing is a hold at 2.25%, consistent with the Bank's stated preference to look through the immediate energy impact while monitoring for second-round effects.
The complicating factors are three. First, the April CPI print, while below consensus, was still the highest headline reading in two years. Second, the CUSMA renegotiation window opens in June, adding tariff-path uncertainty to an already complicated picture. Third, the fuel excise tax suspension introduced in the Spring Economic Update, which took effect April 20 and runs through September 7, will mechanically reduce the headline CPI reading in May. That base-effect noise works in the Bank's favour and may allow another hold in June. But it also obscures the underlying trajectory, making July's decision, with a full MPR attached, arguably more consequential than June's.
Canada's GDP is tracking approximately 1.4% growth in Q1 2026 and is forecast at 1.2% for the full year. The unemployment rate is expected to average 6.5% in 2026 per the Spring Economic Update. A rate hike into that demand environment would be an unusual policy choice, which is why the market is not pricing one. But the Bank has signalled it is prepared to act, and the signal was not rhetorical.
