At the parallel market, the naira shed three points to exchange at N378 to the dollar at the close of trading on Friday afternoon, against N375 it closed with on Thursday, representing a depreciation of 0.8 per cent.
It also weakened further against the pound sterling and the euro as it exchanged at N487 and N405 respectively against N485 and N405 it traded respectively on Thursday.
However, the Nigerian currency maintained losses at N375, N485 and N405 respectively against the dollar, pound sterling and the euro at the Bureau de Change segment of the market.
Currency traders expressed worry over the extension of losses of the naira against other currencies in nearly all the segments of the foreign exchange market.
Four weeks into its implementation, the naira appeared lonely in the face of its trial by macro-economic elements as forces beyond it seemed bent on prolonging its trial.
