BMO Bank has two very different savings tiers: standard branch savings at 0.01% APY and BMO Alto High Yield Savings at 4.50%+ APY. The gap is enormous. Any BMO customer seeking meaningful savings growth should open BMO Alto — which is available to anyone, with or without a BMO branch account.

Bottom line: Use BMO Alto (4.50%+ APY) not standard BMO savings (0.01%). BMO Alto is open to anyone, no branch account required.

  3. Link BMO Alto to your BMO checking via ACH
  4. Transfer savings to checking 1–3 days before needed expenses
