Inflation expected to jump in March as Iran oil shock enters price data

OTTAWA — Statistics Canada will reveal the early impacts of the Iran war’s oil price shock on inflation when the agency reports its consumer price index for March on Monday.

A Reuters poll shows economists widely expect the headline inflation rate rose to 2.5 per cent in March, up from 1.8 per cent in February, according to LSEG Data & Analytics.

RBC senior economist Claire Fan said the bank is also expecting a 0.7-percentage-point jump in the headline inflation rate in March.

“Most of that will just be driven by elevated gasoline prices as well as diesel prices,” she said.

The price of oil has surged in recent weeks after Iran responded to attacks from the United States and Israel by shuttering the Strait of Hormuz, where a fifth of the world’s fuel normally transits.

Fan said the acceleration would be even higher, but the removal last year of the consumer carbon price is still taking some steam out of the annual price comparisons.

She said she expects the headline rate will top three per cent in April when the end of the carbon tax drops out of the inflation calculation.

Prime Minister Mark Carney announced earlier this week that the federal government will remove excise taxes on fuel starting Monday through to Labour Day, a move expected to take 10 cents off the price of a litre of gas and four cents per litre off diesel.

With the tax break coming into effect mid-month, April’s inflation figures won’t see the full benefit of that relief, Fan noted. But by May, she projects the headline inflation rate will be two tenths of a point lower than it would’ve been otherwise with the excise tax removed.

Bank of Canada governor Tiff Macklem said last month he’s also expecting a near-term jump in inflation, but suggested the central bank would look through the initial price shock from the Iran war as monetary policymakers gear up for their interest rate announcement on April 29.

Global oil prices tumbled more than 10 per cent early Friday after Iran said that the Strait of Hormuz is now fully open, allowing tankers to exit the Persian Gulf again and carry crude to customers worldwide.

Beyond the pumps, Fan said she’s watching for how higher energy costs could filter into other parts of the consumer basket. She said the price of jet fuel has seen “quite a substantial increase” in the Middle East conflict, which could spread in the form of higher air freight costs and pricier airfares for consumers.

“But even there it potentially could take a couple of months for that to start actually showing up in consumer prices here in Canada,” she said.

Fan said she expects food inflation to cool somewhat in March, due in part to other past tax changes from the federal government.

Ottawa’s two-month “tax holiday” ending mid-February 2025 applied to restaurant food and some groceries. Food inflation has been higher in recent months, in part because of comparisons to the tax break’s artificially lower prices from a year ago.

Come March, those comparisons will normalize, which Fan said will deliver some relief in food inflation even as items like beef and coffee continue to face price hikes.
