ABUJA, Sept 1 (Reuters) - The Nigerian currency firmed
sharply on the black market on Tuesday, gaining 9.65% to 435
naira against the U.S. dollar, traders said, citing central
bank's move to resume forex sales to bureaux de change.
The currency, which had weakened to a low of 480 naira on
the black market in recent months, firmed from its previous
trade of 477 naira on Friday. On Monday, black market traders
had refused to show quotes as panic set in following the central
bank's announcement about retail currency operators on Thursday.
