The Nigerian naira, on Wednesday, continued its downward slide to close at N707 a dollar at the parallel section of the foreign exchange market.
The figure represents N42 or 7.45 percent depreciation compared to the N658 it traded last week.
Traders at the parallel market bought the dollar at N690 and sold for N707.
At the official market, however, the buying price was N415.14/$while the selling price was N416.14 /$.
Low supply and availability of foreign exchange has been blamed for the slump of the naira.
Earlier on Wednesday, the Senate summoned Godwin Emefiele, governor of the Central Bank of Nigeria (CBN), over inflation and naira devaluation.
The lawmakers accused the apex bank governor of failing to defend the naira.
