It has been a keen contest between the naira and the U.S dollar in the Nigerian black market following an instability in the exchange rate.
The naira has recovered by just N3 against the dollar in the parallel market today, 17th of March, 2016. The naira exhanged for N323 yesterday but goes for a sum of N320 today. It is hoped that the value of the currency in exchange for the dollar will continue to rise as the Nigerian economy currently struggles.
