Dollar supply in the official foreign exchange market rose by 180.59 percent to $440.13m on Friday. This is as the naira closed the week at N1435.53/$ on Friday after what was a turbulent week. According to data from FMDQ Security Exchange, forex turnover rose by 180.59 percent to $440.13m on Friday from $156.86m on Thursday. However, aside from commercial banks, the Central Bank of Nigeria, oil firms and multinationals also sell dollars at NAFEM. The improved liquidity is following moves by the Central Bank of Nigeria to stabilise the foreign exchange rate. Before closing at N1435.53/$ on Friday, the naira traded at an intraday high of N1526/$ and low of N838.96/$. Last week, the apex bank rolled out new circulars and guidelines to boost liquidity and narrow the gap between the parallel and official rates of the foreign exchange market. In its most significant foreign exchange guideline, last week, the CBN ordered banks to adjust their FX exposures. At the parallel market, on Friday, the naira closed at N1,420/$ with a steady demand for the greenback.
