THE NIGERIAN ECONOMY AND NAIRA     The Central Bank of Nigeria (CBN) recently devalued the Naira by seven percent against dollar in order to migrate towards a single exchange rate system for the local currency.      The currency exchange rate of Naira was at #197 to a dollar as at June 2015, but now exchanges at above #400.       However, the people are no longer dealing with the CBN official rate for transactions. Findings have revealed that Bureau De Change (BDC) operators get the dollar from the CBN at #393 but sell it for #494.       The major causes of the depreciation of Naira include the unnecessary importation of goods and services by Nigerians, and the deficit in local production and manufacturing of essential goods and services.       In order to prevent Naira from getting weaker, the government t must put the following into action. Firstly, the government must encourage the consumption of locally manufactured goods and services in order to reduce pressure on the Naira.
