The naira slipped N2.85 against the US dollar at Nigeria's official foreign exchange market on Tuesday, September 15, 2026, closing at N1,329.15 per dollar compared with N1,326.30 the previous day, according to Central Bank of Nigeria (CBN) figures. The marginal 0.2% decline came as JPMorgan formally included Nigerian local-currency government bonds in its newly launched Government Bond Index-Emerging Markets Edge (GBI-EM Edge), giving Nigeria a 7.4% weighting.
FX Market Activity Surges Despite Naira's Small Retreat
Despite the naira's slight depreciation, trading activity in the interbank market surged dramatically. Turnover climbed 174.16% to $262.12 million, up from $95.61 million recorded on Monday, while the number of transactions rose to 172 from 109, according to official data.
Analysts at Coronation Merchant Bank expect the naira to remain relatively stable in the short term, supported by the improvement in Nigeria's external reserves. The analysts also noted that the inclusion of Nigerian local-currency bonds in the FTSE Russell index could provide additional support for the naira over the medium to long term.
Mixed Movements Across FX Markets Last Week
According to a report by Coronation Merchant Bank, the naira recorded mixed movements across the foreign exchange market last week, with the official exchange rate weakening while the parallel-market rate appreciated. At the official market, the naira lost 0.40% week-on-week, with the dollar closing at N1,326.52 compared with N1,321.22 recorded in the previous week.
The currency posted its weakest daily performance on Wednesday, September 9, 2026, when the official exchange rate fell to N1,329.21 per dollar. Meanwhile, the naira strengthened in the parallel market, where the dollar rate declined to N1,385.00 from N1,390.00 a week earlier, representing a 0.36% week-on-week improvement.
Parallel-Market Premium Narrows
The movement in both markets reduced the gap between the official and parallel-market rates. The parallel-market premium narrowed to N58.48 per dollar from N68.78 in the preceding week, although the difference between the two exchange rates remained substantial.
Nigeria's external reserves climbed to $54.61 billion, providing a buffer for the currency. The JPMorgan index inclusion is expected to improve the visibility of Nigeria's domestic debt market among global investors and could support increased foreign portfolio flows into the country's local-currency bond market.
JPMorgan Index Details and Market Impact
The GBI-EM Edge index tracks local-currency sovereign debt from frontier markets, covers roughly $328 billion across 26 countries, and carries an 8% cap per country. Nigeria received a 7.4% weighting in the index, according to BusinessDay reports.
Analysts say foreign investors have not yet moved funds into Nigerian bonds despite the JPMorgan announcement, but the inclusion is expected to enhance the attractiveness of Nigerian debt instruments in the global market.
In a related development, a Federal High Court in Abuja sentenced two Bureau De Change operators to five years in prison each for running BDC businesses without a valid licence from the Central Bank of Nigeria. Justice Obiora Egwuatu handed down the sentences in two separate cases brought by the Economic and Financial Crimes Commission (EFCC), with T.M. Anamaeze as prosecutor in both cases.
