Hello Anabasi,
First off, many thanks for your comprehensive response but I beg to disagree. I don't want to discuss semantics but facts. Neither Turkey nor NC are part of SEPA, let alone regulated by the ECB, so cannot have anything to do with SEPA. I don't know which bank you are using in NC but it seems impossible they provide SEPA payments unless they are running such operations from another banking institution in Europe (not just a correspondent bank in Europe, but originating the payment itself from there). If this is the case, you found a rare treasury which merges the privacy of a non AEOI/CRS country and the operability of an european one.
An IBAN account number does not entail having a SEPA compliant account. There are some countries which impemented IBAN (Turkey is one) but are outright outside SEPA and the EU banking system.
From the information posted in their website, these two banks you mentioned before (Iktisat and Creditw3st) don't even seem to be able to send/receive SWIFT transfers by their own (just like other banks with correspondent account) but the wire apparently must be received by a Turkish bank (under the NC bank account name) and then credited to the final NC bank customer using the details that must be included in an anciliary field of the MT103 message. That's what it's infered from the instructions in their site, I might be wrong there but I cannot tell as I'm not their customer.
I don't mean to say your claims are not true just that, at least, those are not 100% accurate. Again, If you found a bank in NC which provides a unique IBAN under the customer name and processes SEPA payments through it (from a bank in Europe) and direct SWIFT payments, I truly congratulate you.
