How to manage business cash across multiple banks

Spreading business cash across more than one bank can add deposit protection, earn more interest on idle cash and reduce reliance on a single provider. The trade-off is more admin, so set clear roles for each account and track balances in one place.

Key takeaways

  • Give each account a clear job.
  • Keep idle cash where it earns interest.
  • Check deposit protection limits at each institution.
  • Track all balances in one place.

Deposit protection

In Canada, CDIC protects eligible deposits at member institutions up to C$100,000 per insured category. Businesses holding larger balances sometimes spread cash across institutions; check how each provider holds and protects your money, especially fintechs that hold funds through partner institutions.

A worked example

A business keeps two months of expenses in its main account, holds USD in a multi-currency account for US costs, and moves surplus reserve cash to an account that pays interest, reviewing balances every month.

Common mistakes

  • Leaving large balances idle in accounts that pay no interest.
  • Opening accounts without deciding what each one is for.
  • Losing track of balances across banks.
