National Bank Business Investment Account review

CanadaUpdated October 2026

National Bank’s Business Investment Account gives big-bank clients tiered interest that rises with the balance, from 1.25% under C$20,000 to 1.70% from C$100,000 and higher above. It suits businesses keeping reserves with National Bank, though smaller balances earn less than flat-rate fintech accounts.
