The naira on Friday depreciated to N1,487 per dollar at the parallel market from N1,485 per dollar recorded on Thursday.
However, the local currency appreciated at the Nigerian Foreign Exchange Market (NFEM), according to official data.
Figures from the Central Bank of Nigeria (CBN) showed that the indicative exchange rate for the naira improved to N1,417.95 per dollar on Friday, from N1,420 per dollar on Thursday, representing an appreciation of N2.05.
As a result, the margin between the parallel market rate and the official exchange rate widened to N69.05 per dollar on Friday, compared with N65 per dollar recorded the previous day.
Market analysts attribute the mixed performance of the naira to ongoing demand pressures in the parallel market, despite relative stability and improved liquidity at the official window.
The CBN has reiterated its commitment to sustaining reforms in the foreign exchange market aimed at improving transparency, boosting investor confidence and narrowing the gap between official and parallel market rates.
