The issuing bank (or card issuer) is the financial institution that issued the customer's credit or debit card. In the four-party payment model, the issuing bank represents the cardholder's interests: it extends credit (for credit cards), holds the customer's account funds (for debit cards), and approves or declines transactions.
The issuing bank's role in a transaction: 1. Receives the authorization request from the card network 2. Checks if the card is valid, not stolen, and has sufficient funds/credit 3. Applies fraud scoring and risk algorithms 4. Approves or declines the transaction 5. Places a hold on funds (for debit) or reduces available credit (for credit) 6. Pays the acquiring bank at settlement (minus interchange fees) 7. Pays itself back when the cardholder makes their monthly payment
The issuing bank is who the merchant's interchange fees ultimately go to. When Visa's interchange rate for a signature credit card is 1.65%, that 1.65% goes to the issuing bank as compensation for bearing credit risk, funding rewards programs, and extending credit.
Major issuing banks include Chase, Bank of America, Citibank, Wells Fargo, American Express, and Discover. Capital One is notable for issuing high-rewards cards, which carry some of the highest interchange rates — a reason merchants dislike premium cards.
Understanding the issuing bank's role helps merchants understand their costs. Rewards cards (Chase Sapphire, Amex Platinum, Capital One Venture) carry higher interchange rates because the issuing bank funds those rewards from interchange revenue. When your customers pay with premium rewards cards, you're subsidizing their airline miles and cash back.
This is why some merchants prefer cash discount or surcharging programs: to neutralize the cost difference between card types.
A customer uses their Chase Sapphire Preferred card (a premium rewards card): - Visa interchange rate: 2.10% + $0.10 (premium card rate) - This premium rate goes to Chase (the issuing bank) to fund rewards - Contrast: Customer's basic Visa debit card interchange: 0.05% + $0.22 (Durbin regulated) - The same $100 purchase costs the merchant $2.20 with the Sapphire vs. $0.27 with debit
Store credit cards (like Target Redcard or Amazon Prime Visa) are issued by partner banks — Synchrony Bank, Comenity Bank, or Chase are common. The retailer co-brands the card but the bank issues it.
Premium rewards cards carry higher interchange rates because the issuing bank needs that revenue to fund the rewards. Chase Sapphire cardholders earn valuable points; Chase funds those points from the interchange they collect on each transaction.
Liberty Bancard helps merchants understand how their card mix affects costs. Our statement analysis breaks down interchange costs by card type so you can see exactly how much premium rewards cards cost you — and evaluate whether a cash discount or surcharging program makes sense.
