David Rosenberg: The Canadian Banks have entered bubble territory. It’s time to take some profits

The market is rewarding Canada for a very narrow kind of quality: oligopolistic cash generation with low earnings dispersion. That tends to create a self-reinforcing flow loop — index funds, dividend mandates, and low-volatility allocators all concentrate into the same financial complex — but it also means the headline index can look healthier than underlying earnings breadth. In other words, this is less a broad risk-on signal than a liquidity/mandate trade that can persist for quarters even if the real economy is mediocre.

The second-order effect is that leadership in the banks can crowd out everything else listed domestically: smaller financials, rate-sensitive real estate, and cyclicals tied to domestic growth typically lag when the banks become the only credible source of index alpha. If the trade is driven by stability rather than acceleration, multiple expansion can outrun fundamentals; that leaves the group vulnerable to any normalization in credit, mortgage delinquencies, or a faster-than-expected policy easing cycle over the next 1-3 months.

Contrarian read: the consensus may be treating bank-led index strength as evidence of economic durability when it may simply reflect a defensive premium and limited alternatives in the local market. The setup is vulnerable over 6-18 months if loan-loss provisions rise or if U.S. growth/AI leadership re-accelerates, pulling global capital back toward higher beta markets. Falsifiers: a clear tick-up in Canadian bank impairment charges, a sharp drop in 2-year yields, or any guidance reset on net interest margin.
