The Bank of Canada is caught between two forces pulling in opposite directions, and the resolution of tonight's 8 PM deadline will do more to determine Canadian monetary policy over the next six months than any domestic data release on the calendar. On one side: an economy already in excess supply, with a contracting Q4, a soft labour market, and five straight months of PMI readings below 50. On the other: an energy-driven inflation shock that is just beginning to show up in the data and has not yet peaked.

This is the configuration central bankers refer to, carefully and reluctantly, as stagflation risk. It is the scenario monetary policy is least well-equipped to handle, because the conventional responses to inflation and the conventional responses to weak growth point in opposite directions.

What The Data Actually Shows

Canada's February CPI came in at 1.8% -- the softest reading since July of last year, and below the Bank of Canada's 2% target. That number was compiled before the oil shock fully worked its way through pump prices. Since February 28, gasoline has risen approximately 30% nationally to an average of $1.89 per litre. Diesel has surged roughly 38% to $2.32. Furnace oil is up approximately 30%.

TD Economics estimates that a sustained 50% rise in oil prices -- roughly where Canada sits today -- pushes overall inflation approximately 1.2 percentage points higher when fertilizer and transportation cost pass-through are included. Applied to February's 1.8% baseline, that implies a March or April CPI reading potentially approaching 3% before any base-effect adjustments. Desjardins economist Randall Bartlett has noted that food prices and global shipping costs are next in line to reflect the energy shock, as insurance premiums on shipping contracts and fuel surcharges work through supply chains.

The Boc'S Strategic Bind

Governor Macklem framed the March 18 decision carefully. The Bank will look through the immediate inflation spike from energy because, as Senior Deputy Governor Carolyn Rogers noted, the economy is not overheated the way it was entering 2022. There is genuine slack. Unemployment at 6.7% and five consecutive months of PMI contraction mean companies have limited ability to pass cost increases on to consumers. That is the disinflationary backstop Macklem is relying on.

The risk is duration. If the conflict extends into May or June -- which becomes more likely with each deadline extension -- the energy price signal stops being temporary and starts being persistent. Once inflation expectations begin shifting in households and businesses, the BoC loses the luxury of looking through the spike. Oxford Economics has put it plainly: the Bank is likely to wait out the storm, but the longer the storm lasts, the more compelled it becomes to raise rates to contain second-order effects. Vanguard Canada's Ashish Dewan has estimated that a conflict lasting more than two quarters could push the BoC toward a hike, with headline inflation potentially rising 75 basis points and core inflation 30 basis points above current levels.

THREE SCENARIOS FOR APRIL 29

The Bank of Canada's April 29 decision will be shaped almost entirely by what happens between now and then. Three scenarios bracket the range of outcomes. In the first, tonight's deadline produces a ceasefire framework and oil begins retreating from current levels. The March CPI print -- released before April 29 -- shows a spike but with a clear downward trajectory implied. Macklem holds at 2.25% with a dovish lean, possibly signaling a cut later in the year if growth deteriorates further. In the second, the deadline passes with another extension and negotiations continue inconclusively. Oil stays above $100. The March CPI print is alarming. The BoC holds but shifts its language materially toward a hiking bias. Markets begin pricing a May or June hike. In the third, tonight's deadline triggers a genuine escalation -- infrastructure strikes, Iranian retaliation, oil toward $130 or higher. The BoC faces a crisis-mode decision: hold while the situation develops, or move pre-emptively to anchor inflation expectations. This is the scenario where historical precedent offers the least guidance.

What is not in dispute is the structural position Canada occupies heading into tonight: a central bank at the lower end of its neutral range, an economy already running below potential, and an inflation shock arriving from outside its borders that it cannot directly address with monetary policy. The BoC can respond to the consequences of the oil shock. It cannot resolve its cause.
