This week, both the Bank of Canada and Federal Reserve Chair Kevin Warsh leaned hawkish, citing the same underlying story: energy costs from the renewed Iran conflict pushing inflation higher. But the freshest data in each economy is already telling a different chapter of that story. U.S. CPI cooled to 3.5 per cent in June from a 4.2 per cent peak in May, the first monthly decline in the annual rate in five months. The hawkish language landed the same week the inflation print it describes had already started to turn.
The U.S. Print That Undercuts the Talking Points
The June Consumer Price Index fell 0.4 per cent from May on a seasonally adjusted basis, the largest one-month decline since April 2020, according to the Bureau of Labor Statistics. Energy prices dropped 5.7 per cent for the month after climbing in each of the prior three months, as the temporary Hormuz ceasefire that held through most of June eased gasoline costs. Core inflation, which strips out food and energy, eased to 2.6 per cent year over year from 2.9 per cent, its lowest reading since before the May peak. Producer prices told a similar story, falling in June for the first time in nearly a year.
Chair Warsh's reaffirmed line this week, that the Fed has no tolerance for persistently elevated inflation, was calibrated to a 4.2 per cent print that is now a month old. Markets are not fully buying the hawkish framing either: futures pricing implies only about a 10 per cent probability of a rate hike at the Fed's next meeting, according to CME's FedWatch tool, even after the latest round of U.S. strikes on Iran pushed oil back above $80 this week.
Canada's Case Is Even Softer
The Bank of Canada's own numbers make a similarly qualified case for hawkishness. Canadian headline CPI reached 3.2 per cent in May, its fastest pace since December 2023, driven almost entirely by a 33.2 per cent year-over-year jump in gasoline prices. But the Bank's preferred core measures barely moved: trimmed-mean core inflation held at 2 per cent and median core at 2.1 per cent in the same report, both essentially at target. That is the signature of an energy shock passing through the headline number, not of broadening, demand-driven inflation.
Growth data adds to the case for caution rather than tightening. Canadian GDP was essentially flat in the first quarter before rebounding 0.5 per cent in April, the strongest monthly gain since July 2025, with a preliminary 0.1 per cent gain estimated for May. Economists surveyed by Bloomberg have trimmed their 2026 growth forecast to roughly 0.7 per cent. Employment has held up, with 18,200 jobs added in June following an 88,000 gain in May, but that is a labour market holding steady, not one overheating.
What the Inflation Arc Actually Shows
US headline inflation traced a clean arc this year, climbing for three straight months as the Hormuz conflict fed into energy prices, then reversing sharply once the interim ceasefire took hold in June, a shape that is easier to read on a single timeline than in separate monthly headlines.
Headline CPI accelerated for three straight months after the February 28 conflict onset before reversing in June as the interim ceasefire held. That reversal happened before this week's hawkish commentary from either central bank.
The Real Test Is the July Print
The gap between this week's hawkish framing and last month's cooling data is not necessarily a mistake by either central bank. Both Macklem and Warsh are setting policy for where inflation is going, not where it already was, and both have explicitly flagged the risk that renewed fighting reverses June's improvement. That risk is no longer hypothetical. WTI crude has climbed more than 11 per cent over the past three trading sessions on fresh U.S. strikes against Iran, and reports Thursday that Washington is weighing a strike on Iran's main oil export terminal raise the odds that July's energy costs look more like May's than June's.
The next data points that matter are Canada's June CPI, due July 20, and the U.S. July CPI, due August 12. If either shows energy costs reaccelerating, this week's hawkish rhetoric will look prescient rather than premature. If they do not, the gap between what the central banks said this week and what their own numbers showed will have been the more accurate signal.
