Traders said the bank had sold less hard currency than would be expected at a special auction.
Nigeria's central bank has sold around $313 million in a two-month forward auction to clear backlog dollar demand, Citibank wrote in a note to clients on Thursday.
Last week, the central bank held a two-month dollar forward auction to clear a backlog of demand from airlines, manufacturers and other companies, as a currency crisis deepened. It later directed lenders to submit bids again on Monday, traders said.
Traders said the bank had sold less hard currency than would be expected at a special auction, and that bids had been accepted at around a range of 310-350 per dollar.
