Assessment of the interchange fee and the interpretation of its role have prompted serious professional debate in recent years. Beyond the professional debate, competition proceedings were also launched in connection with interbank agreements related to the interchange fee and the setting of the fee, but so far specific regulation has been adopted only in a few countries. The first part of the study describes the function of the interchange fee and the related economic theories, followed by a discussion of issues arising in connection with the interchange fee from the point of view of competition authorities and regulators. The second part of the study presents the results of analyses relating to the Hungarian payment card market and interchange fees. On the basis of these results, we conclude that prudent regulatory intervention, taking into account both primary and secondary market effects, may be justified in relation to the interchange fee, due to the structure and level of development of the Hungarian market.

Összefoglaló A négyszereplős kártyarendszerekben alkalmazott bankközi jutalék (interchange-díj) a fizetésikártya-üzletágban a keres- kedőktől a kártyabirtokosok felé csoportosít át jövedelmeket. Az elmúlt években a jutalék megítélése, szerepének értel- mezése jelentős szakmai vita tárgyát képezte. A szakmai vita mellett több esetben versenyhatósági vizsgálatok is folytak a bankközi jutalékkal kapcsolatos bankközi megállapodások, illetve a jutalék mértékének meghatározásával kapcsolatban, konkrét szabályozásra azonban eddig csak néhány országban láthattunk példát. A tanulmány első része ismerteti a bank- közi jutalék működését és a kapcsolódó közgazdasági elméleteket, majd pedig versenyhatósági és szabályozói szempont- ból mutatja be a jutalék kapcsán felmerülő kérdéseket. A tanulmány második része bemutatja a magyar fizetésikártya- piaccal és a bankközi jutalékokkal kapcsolatos elemzések eredményeit. Ez alapján megállapítható, hogy a magyar piac szerkezete és fejlettségi szintje miatt indokolt lehet egy, a bankközi jutalékokkal kapcsolatos, körültekintő és mind az elsődleges, mind a másodlagos piaci hatásokat figyelembe vevő szabályozói beavatkozás. mnb occasional papers 96. • 2012 5 1 Introduction The interchange fee applied in relation to four-party card systems1 has been the object of intense debate recently and remains a contested issue in terms of regulation and competition law. The costs and price of the systems play an important role in relation to the competing payment systems in terms of both consumers and merchants using the systems and social welfare. Payment with payment cards at a system level constitutes an electronic payment system which is likely to produce potential savings. Payment card payments can support the development of the payment system; aside from modernisation of the system, however, it is unclear whether the various incentives in place in the current payment system genuinely orient parties in the direction of a socially optimal payment instrument. In the systems analysed, with the help of the interchange fee, the individual parties can choose to transfer costs, which may serve the interests of the entire system or the interests of particular parties. The interchange fee is the fee paid by the credit institution (acquirer bank) enabling the acceptance of payment cards to the credit institution issuing the card in the course of the card payment transaction. The interchange fee generates income transfer between card users, non- card users, merchants and banks, which may serve the optimisation of the system and also optimise the profit of the individual parties. Due to the high fees, the representative organisations of merchants who finance the system generally campaign to maximise or abolish the interchange fees. Numerous competition proceedings and regulatory initiatives have been launched in relation to the setting of the interchange fee. This study attempts to present the theoretical basis and the related regulatory and competition policy criteria regarding the interchange fee, and, after a brief description of the Hungarian card market, to discuss the development of these issues on this market. In the first part of the study, following the description of the basic concepts and operation of the four-party card system, we present the major results of economic theory relating to card markets. By examining the role and effect of the interchange fee under various assumptions, the models provide information on its assessment from a competition point of view and its possible regulation. In view of the fact that in addition to the many recently conducted competition proceedings, there are many such proceedings and lawsuits currently in progress in connection with the method of setting the interchange fee, it is essential to reference the relevant competition cases. There is special focus on proceedings conducted in the past and currently by the Directorate General for Competition of the European Commission against the major four-party card systems (Visa, MasterCard). The externalities identified in connection with the interchange fee have raised the need for regulation in many legal systems, and we thus consider it important to address the key issues and dilemmas arising in relation to regulation. We describe in detail the example of Australian regulation, which plays a pioneering role in this area. A brief overview of the market is necessary to understand trends observed on the Hungarian payment card market. Our study references the competition proceedings ending in 2009 (Vj-18/2008/341) and attempts at regulation in 2009 and 2010. The study ends with conclusions drawn from the above. 1 The four parties participating in the transaction are the merchant, the merchant’s bank (acquirer), the cardholder and the bank of the cardholder (issuer). 6 mnb occasional papers 96. • 2012 2 Development and operation of the interchange fee The interchange fee functions as a special element of four-party payment card systems.2 Thorough knowledge of the operation of four-party card systems is necessary for the assessment of the interchange fee. This chapter discusses the parties of the system, features of the transaction, function of the interchange fee and the related regulations.
