MARGIN

1- In savings collection, this is the difference between the rate paid to a customer and the rate at which the bank can invest the funds on the money market.
2- In lending, this is the difference between the rate charged to a customer and the rate at which the bank can refinance itself on the market for the same term.
3- In the case of variable-rate mortgages, the variable-rate adjustment may include a fixed amount of interest to be added to a reference rate or index. This is referred to as the revision margin or fixed portion (e.g. reference index + 2%). These elements are defined in the loan contract and the notice on rate revisions (see index).
