SEPA transfers *within* Norway takes 2-3 working days and you should expect at least that long for payments to arrive from Sweden.
If that is the case for you, I advice you to file a complaint with the Norwegian Financial Authority (Finanstilsynet).
SEPA is required by EU regulation to take maximum D+1. If you make the transfer before your bank's cut-off time for the day, normally 14-ish, the money shall arrive no later than the day after. In my experience SEPA transfers are often faster (hours) if your bank is a direct participant in the European interbank clearing system TARGET2.
Interesting, I had no idea. I assume Justcoin is guilty of some of the delay. Can Andreas or Klaus comment on this? But, I will test the my banking delay directly by performing a domestic SEPA transfer to/from accounts I control. That should give me an idea of the actual SEPA related latency only.
I would like to emphasize that minimizing these banking delays is important to anyone trading in bitcoins.
Another protip: If you trade privately via SEPA, and the transfer takes longer than the expected D+1, it is probably fraud or phishing. I reported two such cases to my bank upon reception of the money, before sending any bitcoins of course, and I was right both times.
I don't understand. You received the money, but it was still fraud?
I don't trade privately via SEPA, for the reason that I am under the impression that SEPA transfers are reversible and subject to possible chargeback (and for quite a long time after payment was received). Do you know if that is correct? What is the risk of accepting SEPA payments vs a wire?
