Mastercard, along with payment providers allpay, APS, PFS, and Sulion, are under investigation by the UK’s Payment Systems Regulator (PSR) regarding anti-competitive collaboration, per Reuters. The PSR said the firms agreed not to compete for each other’s customers on prepaid cards that the government used to distribute welfare payments to vulnerable groups like those who are homeless, victims of domestic abuse, and asylum seekers. All five firms were involved in this practice between 2012 and 2018, according to the complaint. Mastercard said that the incident involved two former employees and that it was isolated to UK prepaid cards, adding that it implemented internal controls and training to ensure that such practices don’t reoccur.
Mastercard is cooperating with authorities, but its involvement in the “cartel” might hinder growth potential in the UK, where it’s trying to catch up to Visa. The UK’s debit and prepaid card market is dominated by Visa, and Mastercard has worked to expand its footprint in the space: In February, NatWest, one of the UK’s largest banks, switched its debit cards over from Visa to Mastercard. It’s possible that the case has a negative financial impact on Mastercard because some issuers and merchants may decide to take their business elsewhere to avoid any association with the case, effectively throttling Mastercard's ambitions in the country. There could also be little impact on Mastercard’s business and growth potential, however, because of its decision to own up to the breach and the measures it put in place to prevent it from happening again.
The recent case adds to mounting scrutiny against certain card network practices.
