Little details that matter

Promotion period: 

From April 1, 2026, to July 2, 2026.

 

Eligible account for the promotion:

U.S. dollar Business Investment Account (BIA) held at National Bank. Accounts opened either before or during the promotional period are eligible.

 

Promotional rate offered: 

Benefit from a 0.75% annual interest rate increase on deposits made into your eligible account during the promotional period, up to a maximum of $1,999,999.99. 

 

The standard interest rate will apply to amounts deposited during the promotional period exceeding $1,999,999.99, as well as to funds already in the account before the promotion began.

 

After the promotional period, all funds in the account will revert to the standard interest rate without the promotional increase.

 

If applicable, a withdrawal made from the eligible account during the promotion period will be deducted from the eligible promotional rate amount deposited during the promotion. 

 

Deposits eligible for the promotion: 

Deposits from an amount held in the client's business current account in the same currency at National Bank. 

 

Illustrative example: 

(Hypothetical rates as of April 1, 2026)

An existing client with a balance of $10,000 in the eligible account before the start of the promotion makes a deposit of $5,000 on April 1, 2026. If the client maintains this balance, they will benefit from an annual interest rate* of 0.95% + the promotional increase of 0.75% = 1.70% on their new deposit of $5,000 during the promotional period. They will benefit from the annual interest rate* of 0.95% on the $10,000 in the account before the start of the promotion, as well as the annual interest rate bonus of 0.05% calculated on the minimum monthly balance maintained in the account during the month.

 

Additional conditions: 

Holding a business current account in the same currency at National Bank is required to benefit from the promotion, as only transfer transactions are available for the Business Investment Account. 

 

Closing the current account will result in the automatic closure of the Business Investment Account without further notice.

 

Unless otherwise indicated, the promotion cannot be combined with any other benefit, offer or promotion.

 

The promotion may be modified or withdrawn without notice. 

 

*This is an assumption because annual interest rates may vary. The Business Investment Account operates by tier and rates are posted on this webpage. 

1. Annual interest rate calculated daily. Rates are subject to change without notice.
 

2. Rate bonus calculated on the minimum monthly balance. Rates are subject to change without notice.
 

3. The rate bonus depends on the account's minimum balance for the month. The bonus is calculated using the number of days in the month and the balance tiers and rates presented in the above table. The more funds you have, the higher your return, since the interest and the rate bonus are tied to your account balance. What’s more, your funds remain accessible at all times.
 

4. The closure of this same current account will result in the closure of the BIA without further notice.
 

5. Our automated telephone service is only available for the CAD currency. 
 

6. Assisted transactions are those performed at a counter in branch, with a representative over the phone or through our automated telephone service.
 

7. Overdraft protection applies to Canadian dollar accounts only. Overdraft protection does not cover overdrafts caused by electronic funds transfers (EFTs). There must be sufficient funds in the account for a company to complete EFTs.
