Canada's inflation trends are looking a lot like the trends in the United States. The headline inflation rate has rolled off relatively sharply. The year-over-year pace is 5.3%; that falls to 3.3% expressed at an annual rate over six months. The annualized pace logs a 1.6% gain over three months. Magically inflation goes from extremely strong to under the pace prescribed by its target. Canada’s CPIx, which excludes the most volatile components of inflation, shows a 4.9% increase over 12 months, a 3.7% annual rate increase over six months and a slightly slower 3.4% annual rate increase over three months. Those metrics track closely the U.S. CPI path. Meanwhile, Canada's core CPI rate (excluding food and energy) shows a 6% gain over 12 months, a 4.3% annual rate increase over six months and a 4.1% annual rate increase over three months that echoes the pattern of the U.S. core. Although Canada has a lower inflation rate on each of its shorter horizons compared with the U.S. core with the three-month inflation rate pace that's a percentage point below the 3-month pace in the U.S., Canada's year-over-year pace for the core is 1/2 of one percentage point higher than in the U.S. It's too soon to say exactly what this means in terms of policymaking and whether we should be paying more attention to the year-over-year pace or to the 3-month pace. But the differences here are not huge.
When the 3-month inflation rate drops sharply, it's an encouraging sign about where inflation is headed next. However, it is not a guarantee. The ‘problem’ with annualized 3-months inflation is that the series is volatile. A drop in inflation over 3 months is a welcome signal, but it is not one that can be relied on up. That is the policy dilemma.
Canada’s year-over-year inflation rate on the CPI peaked at 8.1% in June and has declined to a pace of 5.3% in February. The CPIx pace that excludes the six most volatile items peaked at 6.2% in June and is down to a pace of 4.7% in February. Canada’s core CPI peaked at 5.5% in July and is down to a 4.9% pace in February, the same as its year-on-year pace in January.
