I think owning foreign currency in NK is probably grey-market normalised at this point. However I imagine it's predominantly RMB and USD. The requirement that everything be done by foreigners in Euros is probably serving the purpose you state though. I suspect authorities might look the other way at foreign currency in general, or specific currencies like those I specified, but Euros might be taken as evidence of unauthorised contact with foreigners since there's no other good reason to take them.
