Research & Commentary: Interchange Fee Update

Published June 9, 2010

In an effort to force a reduction of what consumer advocates call “swipe fees” and depository institutions call “interchange fees,” many in Congress are proposing heavy regulation of these fees, which are charged for processing transactions through debit and credit cards.

A new amendment to the Restoring American Financial Stability Act of 2010, sponsored by Senator Dick Durbin (D-IL), would make substantial changes in how fees on debit card transactions and determined and imposed. Combining two of Senator Durbin’s previous amendments addressing interchange fees, the amendment would empower the Federal Reserve to regulate interchange fees and require those fees to be “reasonable and proportional to the costs of the issuer or the payment network.”

The amendment also gives merchants new flexibility in how they are able to manage the fees by changing merchant restraint rules for debit payments. The new rules would prohibit restrictions on both minimum and maximum transaction amounts for debit purchases, and would allow merchants to offer discounts designed to steer transactions towards other networks or to other forms of payment like cash or checking, which is currently disallowed by some networks.

Interchange fees are calculated as a percentage of the transaction amount using a formula incorporating several factors: account authorization costs, fraud and credit losses, and the average bank cost of funds. The fees change over time.

Retailers’ groups say the fees are unfair and that the mandated reduction would be good for the economy. The Merchants Payments Coalition (MPC), for example, argues that the fees amount to a hidden tax of nearly 2 percent on just about every credit card transaction.

Credit providers say the fees are needed to cover the risk of nonpayment, the costs of processing transactions, and the expenses of maintaining the credit system infrastructure. They argue that the fees are justified and fairly reflect the cost of building and maintaining the debit and credit networks that make instant credit possible and beneficial for retailers, consumers, and issuing banks alike. They note that merchants have never contributed a penny to the cost of building the networks and that their participation in those networks is optional.
