The Central Bank of Nigeria has responded to talks about the new naira notes being only redesigned in colour, stating that the change of ink “is in itself a security feature.” The CBN authorities also claimed that the bank had no luxury of time to execute a broad redesign, while claiming that it only wanted to tackle an identified problem. The CBN’s Director of Currency Operations, Ahmed Umar, said this at a three-day workshop organised by the Nigeria Deposit Insurance Corporation (NDIC).
