Statistics Canada reported on October 19 that September CPI rose 3.1% from a year earlier, a tenth below the 3.2% consensus. The core measures the Bank of Canada watches told a different story: CPI-trim slowed to 1.8% and CPI-median to 1.9%, both under the 2% target. Nine days later the Bank raised its policy rate to 2.5%.
Why a Central Bank Hikes Into Soft Core Inflation
The decision rests on mechanism rather than the current print. In its October 28 statement the Bank said it acted to reduce the risk that continuing high energy prices spread broadly to the prices of other goods and services. It added that further increases could be needed but that Governing Council agreed to proceed carefully given the uncertainties.
The Monetary Policy Report raised the forecast for 2027 inflation to 3.1% from 2.0% and moved the return to the 2% target to the middle of 2028. Governor Tiff Macklem said the main argument for an increase was that energy prices are higher, are expected to stay higher, and that cost pressures are building.
Core measures are the test of whether that spread has begun, and so far it has not. CPI-trim has fallen from 3.1% in September 2025 to 1.8%, and CPI-common slowed to 2.4% from 2.6%. The hike is a pre-emptive move against second-round effects, not a response to broad price pressure already in the data.
Headline CPI crossed above CPI-trim in March 2026 and the gap reached 1.3 percentage points in September, the pattern of an energy-led rise rather than a broad one.
Total CPI moved above CPI-trim in March 2026 and the gap reached 1.3 percentage points in September. CPI-trim excludes the 40% of the basket with the most extreme monthly price changes.
What Macklem Told Parliament on November 3
Appearing before the House of Commons Standing Committee on Finance on November 3, Macklem said further rate hikes may be needed because the war in the Middle East is keeping energy prices higher. The Bank sees GDP growing 1% in 2026 and about 2% in both 2027 and 2028, after growth of 3.3% in the second quarter and an estimated 2% in the third. Growth is expected to slow in the fourth quarter on new US tariffs before recovering in 2027.
He also said higher oil prices and refinery margins are raising costs for consumers and businesses, with greater pass-through to inflation expected over the coming months. Scotiabank Economics noted that monthly GDP has come in softer than expected since the hike, and that the Bank has stressed data dependency and the lagging effects of rate increases.
Oil gave a mixed signal this week. Reuters reported that oil fell more than 7% on Monday on hopes for an end to the war with Iran, and Scotiabank Economics noted prices were about 2% higher on Tuesday.
The Transmission Runs Through the Five-Year Yield
The Government of Canada five-year yield closed at 3.51% on November 3, up 0.03 percentage points on the day and down 0.11 points over the past month. It remains 0.80 points above its level a year ago, according to Trading Economics. The 10-year yield stood at 3.79%.
Fixed mortgage rates are priced off the five-year yield, while variable-rate mortgages and home equity lines follow the policy rate directly. Households renewing a fixed-rate mortgage face a benchmark 0.80 points higher than a year earlier, and variable-rate borrowers face the possibility of a further increase.
The data calendar tests the Bank framing quickly. Budget 2026 is tabled on November 5, with the Parliamentary Budget Officer warning that deficits will average $3 billion higher annually over five years. The Labour Force Survey for October follows on November 6, and the next CPI release is due November 16. A CPI-trim reading back above 2% would be the first evidence that the spread of energy costs has started.
