A brief payment delay on a covered bond from Norway’s Sør Boligkreditt that matured last month and which was due to an operational error has no credit impact and is extremely unlikely to happen again, according to Moody’s, which rates the issuer’s covered bonds Aaa.

Payment on a Nkr30m (Eu3.66m) maturing covered bond of Sør Boligkreditt, the issuer of Norway’s Sparebanken Sør, was delayed by three days over last weekend because an amendment to the structure three years ago was not correctly registered in a payment system, according to an official at the issuer.
