LAGOS, March 24 Nigeria's naira firmed to 390
per dollar on the black market on Friday, up 2.6 percent from
its previous session and near the central bank's rate for
consumers, traders said.
The central bank has been intervening on the official market
to try to narrow the currency spread with the black market rate,
which was 520 to the dollar a month ago after it devalued the
naira for retail customers to 375.
On the official interbank market, the currency was quoted at
307 on Friday. February's partial devaluation effectively
created multiple exchange rates in Africa's biggest economy.
