The Euro Payments regulation was the foundation for the decision to create a Single Euro Payments Area (SEPA). The European Central Bank has created the TARGET2 interbank network that unifies the technical infrastructure of the 26 central banks of the European Union (although Sweden has opted out). SEPA is a self-regulatory initiative by the banking sector of Europe as represented in the European Payments Council (EPC). The European Union made the scheme mandatory through the Payment Services Directive published in 2007. Since January 2008, all countries were required to support SEPA credit transfer, and SEPA direct debit was required to be supported since November 2009. The regulation on SEPA payments increased the charge cap (same price for domestic payments as for cross-border payments) to €50,000.
