The Bank Insurance Model ('BIM'), also sometimes known as 'Bankassurance', is the term used to describe the partnership or relationship between a bank and an insurance company whereby the insurance company uses the bank sales channel in order to sell insurance products.

BIM allows the insurance company to maintain smaller direct sales teams as their products are sold through the bank to bank customers by bank staff.

Bank staff and tellers, rather than an insurance salesperson, become the point of sale/point of contact for the customer. Bank staff are advised and supported by the insurance company through product information, marketing campaigns and sales training.

Both the bank and insurance company share the commission. Insurance policies are processed and administered by the insurance company.

BIM differs from 'Classic' or Traditional Insurance Model (TIM) in that TIM insurance companies tend to have larger insurance sales teams and generally work with brokers and third party agents.

An additional approach, the Hybrid Insurance Model (HIM), is a mix between BIM and TIM. HIM insurance companies may have a sales force, may use brokers and agents and may have a partnership with a bank.
