Canadian Inflation, Oil and the Loonie: Separating Gasoline from Underlying Price Pressure

Key takeaways

1. Canadian CPI rose 3.1% year on year in September after 3.0% in August, slightly below a 3.2% consensus; excluding gasoline it slowed to 2.2% (Statistics Canada; VFunded).

2. Brent fell 1.7% to $108.01 in Asian trade after the US waived sanctions and tariffs on Russia, which may increase Russian fuel exports (Reuters).

3. For oil-exporting currencies, separate the energy channel that lifts headline inflation from the underlying measures the central bank responds to.

The development

Statistics Canada reported at 12:30 UTC on Monday 19 October that the consumer price index (CPI) rose 3.1% year on year in September, after 3.0% in August. The acceleration was led by gasoline, up 27.8% year on year from 22.8%. Excluding gasoline, the CPI rose 2.2% after 2.4%. Energy prices rose 19.0%, while food purchased from stores slowed to 1.7%. On a seasonally adjusted monthly basis, the CPI rose 0.4% (Statistics Canada).

Market previews had expected 3.2% (VFunded calendar; Reuters described the print as slightly below expectations). The Canadian dollar pared earlier gains and was up 0.27% at C$1.41 per US dollar (Reuters). Oil was weaker: Brent fell 1.7% to $108.01 in Asian trade after President Donald Trump waived sanctions and tariffs on Russia that may lead to more Russian fuel exports (Reuters).

Market transmission

Oil reaches the Canadian dollar through two channels that can work against each other. Higher crude prices improve Canada's terms of trade, the ratio of export to import prices, which tends to support the currency. Higher fuel prices also lift headline inflation, which might suggest tighter monetary policy.

The Bank of Canada (BoC) looks through much of the energy effect if underlying inflation is contained. Monday's report showed exactly that split: headline up, ex-gasoline down. One strategist told Reuters that the softer report reduced pressure on the BoC to raise rates at next week's meeting. That reduced rate-hike channel explains why the currency gave back part of its gain even as headline inflation rose.

What to monitor next

• The BoC's preferred core measures, CPI-trim and CPI-median, as reported in the Statistics Canada release tables.

• The BoC decision next week, and market pricing for a hike.

• Brent and the US decision on Russian sanctions, which the administration said it would assess over the coming weeks.

• Canadian retail sales on Friday 23 October (Newsquawk) and Alberta's non-binding referendum result.

Reusable lesson

When a headline inflation figure is driven by one volatile item, rebuild the picture without it. A rising headline with a falling ex-energy rate usually signals less pressure on the central bank, not more. Apply the same check to any energy-exporting economy.

Invalidation and risk

A renewed oil spike, for example from Gulf shipping disruption, would raise both the terms-of-trade support and inflation risk at once. A stronger underlying reading in the BoC's core measures, or a broad dollar move, could also dominate the CPI signal.
