CIBC economists say Canada's inflation is mostly a fuel story, unlike the broader US problem
The Federal Reserve's quarter-point rate increase in September has strengthened bets that the Bank of Canada will deliver a rate hike of its own on October 28.
New research from CIBC Capital Markets suggests mortgage brokers should not treat that move as a done deal.
In an October 6 report, Helen Lao, an economist at Toronto-based CIBC Capital Markets, argued that Canada and the US face the same energy shock from the Iran conflict, but their inflation problems are different in kind.
"But look past the headline decision and at what's driving it, and the case for a parallel Canadian hike at this moment gets much weaker," she wrote.
Canada's is narrow and largely fuel-driven, she wrote. America's is broad and more likely to stick.
The analysis runs against a shifting consensus. UBS, Manulife, Oxford Economics and Scotiabank have pulled their forecasts forward, and a growing number of major forecasters now expect an October increase from the current 2.25% overnight rate.

Why gasoline, not demand, drives Canada's inflation
Canada's consumer price index (CPI) rose 3% year over year in August, about one percentage point above the Bank of Canada's 2% target.
CIBC estimates that about 0.8 points of that gap comes from above-average gasoline prices. Spillover into airfares and travel tours adds another 0.3 points.
"In Canada, inflation is much less broad-based," Lao wrote.
Only 38% of the country's 55 major CPI components are rising faster than 3% a year, six points above the 1999–2019 average.
In the US, about half of the more than 100 categories in personal consumption expenditures (PCE), the Fed's preferred gauge, are running above that pace.
Gasoline makes up 4% of Canada's CPI basket and about 2% of US PCE.
"The result is that, should gasoline prices begin to abate, it could represent a more meaningful cure for headline inflation north of the border," the report said.
South of the border, tariffs and artificial intelligence (AI) demand explain about 0.9 points of the 1.4-point overshoot.
"The tariff shock has also landed far more heavily on US consumers than on Canadians," Lao wrote.
What a Bank of Canada rate hike would mean for brokers
CIBC expects one more Fed hike. The report said Canada "could follow suit in 2027."
The timing, the report said, "will be a made-in-Canada story that will reflect not only its more favourable starting point on underlying inflation, but also the potential challenges to growth in the face of elevated US tariffs and trade uncertainties ahead."
The central bank itself appears less patient. Governor Tiff Macklem, in his recent Halifax speech warning that growth could halve, said: "Two things probably have to happen if you're too slow: One is, you're going to have to raise rates very quickly."
Royal Bank of Canada (RBC) economists Nathan Janzen and Claire Fan, who see the Bank's next move as a hike rather than a cut, described the decision as finely balanced.
"Incoming data will matter for the October decision, with communications from the BoC continuing to suggest it will be a close call," they said.
For variable-rate clients, a quarter-point increase would pass directly through the prime rate, now 4.45%.
Fixed-rate borrowers are already feeling pressure as lenders reprice in step with rising bond yields.
The next signal arrives October 19, when Statistics Canada publishes September inflation data. UBS expects the annual rate to reach 3.3%.
