Canada's annual inflation rate climbed to 3.2% in May, its fastest pace since late 2023, driven almost entirely by a single line item. Gasoline prices rose 33.2% year over year, the direct consequence of the Strait of Hormuz disruption that has defined Canadian energy costs since February.
Strip out gasoline and the picture looks very different. The Bank of Canada's preferred core measures, CPI-trim and CPI-median, came in at 2% and 2.1% respectively in May, both essentially unchanged from April and sitting almost exactly on the Bank's 2% target. The headline number and the underlying number are telling two different stories, and the Bank of Canada has said clearly which one it is listening to.
Why the Bank Has Held Five Times in a Row
The Bank of Canada held its policy rate at 2.25% on June 10, the fifth consecutive hold since October 2025. Governor Tiff Macklem was explicit about the reasoning: the Bank is looking through the near-term impact of energy prices on headline inflation and will not let higher energy prices become persistent inflation.
That stance has been defensible specifically because the core measures have stayed anchored. A central bank can tolerate a temporary, externally driven spike in headline inflation if the broader economy is not generating inflation on its own. Canada's real GDP edged down 0.1% in the first quarter, following a 1.0% annualized decline in the fourth quarter of 2025, a technical recession by most definitions. A soft economy generating 2% core inflation gives the Bank room to hold rather than hike into a weakening labour market.
The Timing Problem Nobody Has Flagged Yet
Oil has fallen below $70 a barrel this week for the first time since before the conflict began, as tanker traffic through the Strait of Hormuz continues to recover. That decline should show up directly in June's gasoline inflation figure, and by extension in June's headline CPI print.
The problem is sequencing. June CPI data will not be released until July 20, five days after the Bank of Canada's July 15 rate decision. The most encouraging headline inflation news of the year, the unwinding of the exact gasoline shock that pushed May's number to a 29-month high, will not exist yet in any form the Bank can cite on decision day. The Bank will walk into July 15 with May's 3.2% print as its most recent hard data, even though the oil market has already moved on from the story that produced it.
This is not a reason to expect a hike. Bond markets currently price a high probability of no change on July 15, with only a 2% implied probability of a 25-basis-point increase. But it means the Bank's July 15 communication will likely lean more heavily on forward-looking language, what it expects June and July data to show, than on the backward-looking CPI print actually in hand, because the print in hand is the most stale and least representative one would want to use to justify the call the data is widely expected to support.
Where the Fed Pulls the Other Way
The Bank of Canada's comfort with holding sits in direct contrast to its counterpart south of the border. The Federal Reserve under Chair Kevin Warsh struck a notably more hawkish tone at its June meeting, with the dot plot showing nine of eighteen committee members projecting at least one rate increase before year end. The U.S. Dollar Index broke above 100 for the first time since May 2025 on that signal alone.
The Fed and the BoC are reacting to the same global event, the Hormuz-driven oil shock and its unwind, but reaching different conclusions about what it means for policy. The Fed's focus on core PCE, due Thursday and expected to edge up to 3.4%, is centred on a stickier domestic inflation picture less tied to the energy swing than Canada's core measures have been. Canada's core inflation has stayed anchored through the same oil shock that is feeding U.S. hawkishness.
The result is a widening gap between where North American short-term rates are expected to go, a gap that is already visible in the bond market: the Government of Canada 10-year yield fell to 3.36% this week even as U.S. Treasury yields have been pulled higher by Fed repricing, a divergence in direction that has not been this pronounced since the conflict began.
Canadian headline inflation has tracked the oil shock closely since February, while the Bank's core measures have stayed within a narrow band near target throughout the same period.
CPI-trim excludes the most extreme monthly price changes to isolate underlying inflation pressure. The gap between headline and core widened to its largest point of the cycle in May, entirely on gasoline.
What the July 15 Decision Actually Hinges On
Markets imply roughly a 15% chance of a hike by the September 2 decision, up from near zero earlier in the cycle, which reflects accumulated uncertainty about whether elevated headline inflation eventually broadens into core measures rather than any specific data point pointing that direction yet. For July 15 specifically, a hold remains the heavily favoured outcome.
The more useful question for advisors is not whether the Bank holds on July 15, it almost certainly will, but what language it uses to describe the gap between May's stale 3.2% print and the oil market's subsequent reversal. A Bank that explicitly flags the expected June reversal in its statement is signalling more confidence in a near-term hold path than one that stays silent on the timing mismatch.
