Bank of Montreal raises prime rate to 4.70 percent: what it means for Bank of Montreal stock

Bank of Montreal (ISIN CA0636711016) raised its Canadian-dollar prime lending rate from 4.45 percent to 4.70 percent effective October 29, 2026, according to the bank's official release dated October 28, 2026. The change gives the bank's latest operating update a direct lending-rate reference.

Rate change takes effect October 29

The release distinguishes the announcement date from the effective date. BMO announced the move on October 28, 2026, while the 4.70 percent rate applies from October 29, 2026.

The central figure is the 25-basis-point increase from 4.45 percent to 4.70 percent. The release does not quantify the effect on BMO's earnings or loan demand, so the rate change is best read as a product-pricing update rather than an earnings forecast.

What does the rate mean for BMO?

BMO said it serves clients across Canada and the United States through personal and commercial banking, wealth management, global markets and investment banking. Its total assets were CAD 1.5 trillion as of July 31, 2026, according to the same company release.

Stock price and next signal

The prime-rate announcement adds a current operating data point, while the next earnings update will determine whether the bank's reported performance is changing alongside lending rates. At 11:07 a.m. CET on October 29, 2026, Bank of Montreal stock was trading intraday at EUR 156.80 at Lang & Schwarz.
