The Networks establish the base fees. Typically the Merchant has a contract with their Acquirer (the company which processes card transactions for the Merchant) which defines their fees.The fee is shared by the Acquirer, the Issuer (Chase), and the Network (VISA). But, yes, if the fee is lower, or capped, the issuer receives less.
