Drop in cardholder rewards and loyalty programmes?
Tan said that Bank Negara had conducted a cost study on the banks’ excess interchange fee revenue. After accounting for the transaction related costs, this excess revenue is used mainly to fund cardholder rewards and loyalty programmes.
“Thus, the revision of the interchange fee rates after the framework, will not impact the banks’ profitability.
“Consumers are also better off as any reduction in the cardholder rewards and loyalty programmes would make payment card acceptance more affordable and lessen the pressure on merchants to pass on the cost by raising the price of goods and services,” he said.
Cardholder rewards and loyalty programmes are funded through the interchange fees, which constitute the main component of the MDR paid by the merchants.
Merchants are likely to recover such cost through higher prices of goods and services.
Consequently, consumers who do not use payment cards may end up subsidising the cardholder rewards and loyalty programmes enjoyed mostly by premium cardholders.

“Consumers are also better off as any reduction in the cardholder rewards and loyalty programmes would make payment card acceptance more affordable and lessen the pressure on merchants to pass on the cost by raising the price of goods and services,” he said.
