• All main measures of core inflation were soft again last month
  • Headline and core measures are tracking in line with BoC’s January MPR
  • The BoC will want a lot more evidence this isn’t just another temporary soft patch
  •  Mild reaction in Canadian markets
 
  • Canadian CPI m/m % / y/y %, NSA, January:
  • Actual: 0.0 / 2.3
  • Scotia: 0.1 / 2.4
  • Consensus: 0.1 / 2.4
  • Prior: -0.2 / 2.4
  • Trimmed mean CPI m/m % SAAR: 1.1 (prior revised to 0.55% from 1.1%)
  • Weighted median CPI m/m % SAAR: 1.6 (prior unrevised from 0.5%)
  • Traditional core ex-food & energy % SAAR: 1.5 (prior unrevised to 3.1%)

Canadian core measures of CPI inflation were soft again last month. Markets reacted by driving a slight decline in Canadian government bond yields including about a 2bps drop in the 2s yield and a mild depreciation of the Canadian dollar of about a quarter of a cent to the USD.

All three measures of core CPI were soft in m/m terms at a seasonally adjusted and annualized rate (SAAR). See charts 1-3. Traditional core (ex-food and energy) was up by only 1.5% m/m SAAR. Weighted median CPI that captures inflation at the 50th-percentile point of the basket was up 1.6%. Trimmed mean CPI that lops off the top and bottom 20% of the basket after sorting from highest to lowest weighted contributions was up by just 1.1%. Only trimmed mean CPI was revised for the prior month to 0.55% from 1.1%).

Why such a mild reaction? One reason is that the market has been trained to understand that the BoC is on a prolonged hold as it evaluates upside and downside risks and the combination of cyclical and structural drivers alongside potential changes to fiscal policy and trade policy. That’s a patient debate and reacting in overly hasty fashion could be disastrous.

Another reason is that the numbers are of no clear surprise to the BOC. The January MPR had 2.0% y/y for headline CPI and the first month of the quarter was 2.3%. There are a lot of transitory factors from a year-ago that will be working through. One is that upward HST relief effects on y/y total CPI start to expire next month and more fully by March after which the elimination of the consumer portion of the carbon tax turns y/y upward.

Further, trimmed mean CPI and weighted median CPI were expected by the BoC to average 2.5% y/y and the January figure is at about that.

There is also the important issue of requiring much more data to avoid being fooled by a potentially temporary soft patch. Something similar was witnessed in early 2024, for instance, after which the m/m SAAR measures of core inflation all took off higher. Short-sighted markets react to short-term data. Central banks should not.

The gyrations in services versus core goods (ex-food and energy) inflation also merit caution. Services inflation had skyrocketed in December and fell back in January (chart 4). Most of that services acceleration and then deceleration was in services ex-shelter (chart 5). Core goods inflation was previously soft and suddenly accelerated by the most since mid-2025 (chart 6).

Breadth is also still rising (chart 7). It’s not alarming, but if it continues, then it will be of rising concern to the BoC.

There may also be other temporary distortions. The heat is finally coming out of how CPI measures rented accommodation. This follows a large surge on the back of an influx of temporary residents made up of international students, temporary foreign workers and asylum seekers. Tighter immigration policy has tamped down the temporary resident numbers and cooled rental market pressures until a new equilibrium is achieved.

There could also be temporary weather effects that tamped down many prices as consumers stayed in from one of the coldest and snowiest winters in years.

On the flipside is that the high seasonal adjustment factor applied to traditional core CPI suggests that this measure of inflation would have been softer if an SA factor would have been more in line with prior months of January (chart 8). There is a recency bias to how SA factors are calculated that is somewhat unthinking and automatic.
