As a government of the country, Nigeria has the power to regulate the price of Naira to dollar and can make it equal if they wish to. I was come across a news before or heard from someone saying that there was a time Nigeria Naira to Dollar was equal I.e $1 = N1; that happened long time ago when the Naira was very much of value at that time. Dependency on imported goods is amongst the reason our Naira is depreciating and also the monopoly that is happening in the black market is also having an effect on the price.
