I think OP's point was that SEPA and IBAN are completely different things. SEPA is the Eurozone area that treats all transfers as domestic - usually free or near-free, and fast (max 1 day normally, max 10 seconds for instant transfer). IBAN is just a numbering scheme to uniquely identify bank accounts worldwide. It has nothing to do with transfers. The closest thing would be SWIFT, though that's just an information protocol and says nothing about fees or times.
