Share WITH the premium between the parallel market and the Investors and Exporters Foreign Exchange (IEFX) rate estimated at N71, the Naira-for-Dollar policy of the Central Bank of Nigeria (CBN) is likely to reduce the gap, say experts at Financial Derivatives Company (FDC) Limited. Already, Naira fell against the U.S. dollar at the Investors & Exporters (I&E) window of the foreign exchange market on Friday, data from the FMDQ Security Exchange where forex is officially traded showed. Also, the currency weakened at the parallel market. Naira closed at N410.00 at the trading session of the I&E window on Friday, a N1.00 or 0.25 per cent devaluation from N409.00 it closed at the previous session on Thursday.
