The Central Bank of Nigeria strengthened its exchange rate peg slightly to 196.98 naira against the dollar on the interbank market on Monday from 197 it set last week, traders said.
Traders said the regulator sent a message announcing the adjustment which is the eighth since the bank introduced tight currency controls in February.
The bank has resisted calls to further devalue the naira in the face of a plunge in vital oil revenues. It devalued the currency last November and later pegged the exchange rate in another de facto devaluation.
It instead resorted to rationing dollar supply by restricting access to hard currency for import of certain items, frustrating businesses.
Vice president Yemi Osibanjo has said Africa’s biggest economy will keep the currency restrictions for now to preserve the country’s foreign reserves but will eventually relax them.
On the parallel market, the naira closed flat at 224 to the dollar on Monday. The bank has been selling dollars twice a week to the parallel market since July, traders said, citing that the regulator is keen to narrow the spreads in both markets
