Nigeria’s foreign exchange reserves have soared to a six-year high, hitting $42.225 billion as of September 25, 2025, according to data from the Central Bank of Nigeria (CBN). This milestone marks a significant increase of $692 million in just 18 days and reflects a steady upward trend since mid-July 2025. The last time reserves approached this level was in September 2019, when they stood at $41.992 billion.
Key Drivers Behind the Surge
Despite fluctuations in global crude oil prices, which have dipped below the 2025 budget benchmark of $75 per barrel, Nigeria’s oil sector remains a cornerstone of its foreign exchange earnings, contributing roughly 90% of the total. Experts point to several factors fueling this reserve growth:
- Increased Oil Production: Higher crude oil output has bolstered export revenues, significantly boosting foreign exchange inflows.
- Improved NNPC Management: Enhanced transparency and efficiency at the Nigerian National Petroleum Corporation (NNPC) have played a critical role, according to Dr. Muda Yusuf, an economist and former Director General of the Lagos Chamber of Commerce and Industry.
- Macroeconomic Reforms: A more stable economic environment has restored investor confidence, driving autonomous inflows from sources such as diaspora remittances and non-oil exports.
- Reduced Fuel Imports: The local supply of refined petroleum products, notably from Dangote’s refinery, has eased pressure on the foreign exchange market by lowering import bills.
- External Borrowing: Foreign currency loans have further strengthened reserves, as these funds are held by the CBN while expenditures are primarily in naira.
Expert Insights
Dr. Yusuf emphasized the role of a liberalized foreign exchange market in attracting inflows. “The improved macroeconomic environment is fostering confidence, which is driving autonomous inflows from diaspora remittances and export proceeds,” he noted. He also highlighted the positive impact of CBN reforms, which have curbed speculative activities in the forex market.
Damilare Asimiyu, Research Head at Afrinvest, underscored the robustness of Nigeria’s reserves, which now provide over nine months of import cover—a strong indicator of external sector stability. “Resilient portfolio inflows, sustained oil output, and stronger remittances are key drivers,” Asimiyu said.
Abubakar Ardo, a Bureau De Change operator, attributed the reserve growth to tighter CBN policies, including stricter forex access and import monitoring, alongside rising diaspora remittances and renewed foreign investor interest in Nigerian assets due to attractive bond yields.
CBN’s Role and Outlook
CBN Governor Olayemi Cardoso, speaking after the 302nd Monetary Policy Committee meeting, reported that reserves had climbed to $43.05 billion by the end of August 2025, bolstered by a 20.46% growth in the oil sector in Q2 2025. He emphasized that ongoing reforms have stabilized the economy and restored confidence in the naira. “Nigerians can trust the CBN. FX and reserve stability are here to stay,” Cardoso affirmed.
Looking ahead, sustaining this growth will depend on maintaining reforms, ensuring oil production stability, and managing debt sustainability, as foreign loan repayments could strain reserves. Dr. Yusuf noted, “The oil and gas sector remains critical, and we must ensure debt service commitments don’t undermine these gains.”
A Stronger Economic Position
With reserves now exceeding nine months of import cover, Nigeria is in a robust position compared to other emerging markets, where six months is considered a benchmark for stability. The combination of higher oil revenues, prudent CBN policies, and growing investor confidence signals a positive trajectory for Nigeria’s economic resilience.
