Canada’s major bank stocks faced renewed selling pressure on Friday after Statistics Canada reported a 2.4% month-over-month surge in producer prices for March — the sharpest single-month increase in recent memory — driven largely by energy and chemical cost escalation tied to the ongoing Iran conflict. Royal Bank of Canada (TSX: RY) and Bank of Montreal (TSX: BMO) each declined approximately 0.5%, while Toronto-Dominion Bank (TSX: TD) also inched lower. The data reignited concern that the Bank of Canada may be forced to consider rate increases after a prolonged easing cycle, which would directly pressure bank net interest margins and loan growth.

The producer price spike matters for banks because it feeds into broader inflation expectations. The Bank of Canada cut rates to 2.25% earlier in the cycle to stimulate a slowing economy, and market consensus had broadly expected rates to stay flat through mid-2026. A sustained producer price trend — particularly one driven by energy costs that feed into virtually every sector — complicates that outlook. Higher rates would slow mortgage origination, compress consumer credit demand, and potentially increase provisions for credit losses as household balance sheets come under stress. RBC’s own chief risk officer flagged earlier this year that retail loan losses were expected to remain elevated through 2026 due to lagged effects of prior rate hikes and ongoing mortgage renewal shocks.

That said, Canada’s Big Six entered 2026 in strong fundamental shape. RBC reported Q1 2026 revenue growth of 7.3% and net income up 13% year-over-year. TD posted adjusted EPS of $2.44, up 12%, with particularly strong performance in U.S. banking and wealth management. BMO beat analyst expectations despite restructuring charges, driven by cleaner credit trends and improved revenue diversification. All six banks beat consensus estimates in the first quarter, and capital ratios remain well above regulatory minimums.

The next major catalyst for Canadian bank stocks is Q2 2026 earnings, expected to begin reporting in late May. Between now and then, any Bank of Canada communication that signals rate hike consideration will be the defining variable.
