For much of 2024 and 2025 Nigeria’s currency has slid and bounced but never quite found firm footing. The Central Bank has deployed reserves, tightened rules, opened windows and spoken of market reform. Yet the naira remains vulnerable. This is not a story of a single failed manoeuvre. It is a tangle of policy signals market structure fiscal stress and incentives that together keep pushing the currency down.
This investigation shows how repeated central bank interventions have treated symptoms not causes. The CBN can supply dollars at moments of strain and sometimes calm markets. Nevertheless, reforms need to fix chronic foreign exchange shortages. They must align fiscal incentives and dismantle parallel channels. Otherwise, the interventions will keep buying time rather than securing a durable rate.
Below we set out the data, the institutional responses three regional case studies and a pragmatic policy road map.
1. What the CBN has actually done and what those actions buy
Since the exchange market reforms of 2023, the CBN has used a combination of direct sales to authorised dealers. It has intervened in the Investors and Exporters window. Additionally, it has implemented regulatory changes to tighten the supply side.
The central bank now publishes daily NFEM rates and has been more transparent about market operations. Yet interventions remain episodic and conditional on reserve availability and oil receipts.
As reserves recovered through 2025 the CBN could afford larger sales and reassurances to markets. The central bank reported a multiyear high in foreign reserves in November 2025. This was due to stronger oil receipts and improved balance of payments flows.
CBN announcements about licensing and stricter oversight of foreign exchange dealers serve a purpose. They aim to shrink illicit channels. They also aim to bring more turnover into formal venues.
Recent regulatory moves included licensing a new cohort of authorised bureaux de change under tougher capital rules. These moves also included an explicit ban on street trading of forex. Those steps aim to shore up transparency. However, they do not raise long term dollar supply to match demand on their own.
2. The market signal. Official rates and parallel reality
Official daily NFEM rates now sit in a band. This band reflects a volume weighted average of trades in the formal market. The CBN posts the daily NFEM series and traders watch it closely for the official closing and mean rates. But the market is still segmented in practice. Traders and corporates price risk around the ease of accessing dollars on the day not the theoretical average.
The naira was quoted in the official market at recent close. It was in the mid one thousands per dollar. This shows a fragile stability after central bank actions. The CBN rate tables show daily fluctuations. They also reveal that the official figures are sensitive to short term flows. The figures are affected by technical operations.
3. Why interventions fail to produce lasting appreciation
There are six structural reasons the naira keeps slipping despite interventions
Supply shortages beyond the bank’s balance sheet
The CBN can draw on reserves to sell dollars. But reserves are finite and influenced by oil export receipts foreign portfolio inflows and sovereign obligations. Sustained supply gaps from trade deficits or weak oil production cannot be filled from reserves alone without costly depletion.
Market segmentation and parallel channels
Even after unification reforms large pockets of demand meet supply off market. Informal trade in cash and unlicensed bureaux still transmit dollar demand into premium segments. Tightening licences helps. However, it will not erase the incentives for parallel activity. This is true unless formal channels supply more competitive pricing. Faster execution is also required.
Fiscal behaviour and import appetite
A government running sizeable primary deficits will keep pressure on FX. An economy that continues to import large volumes of goods will also keep pressure on FX. Where fiscal revenues fall short, reserves are implicitly substituted for external financing. This substitution weakens the currency unless imports or fiscal deficits are compressed.
Expectation and pass through
When agents expect further depreciation they hedge by buying foreign currency now. That creates a self fulfilling cycle where interventions calm markets temporarily but do not change expectations anchored in structural weakness.
Policy inconsistency and signalling problems
Frequent shifts between tightening and easing occur. Mixed public messages from fiscal and monetary authorities also appear. These issues undermine credibility. Markets interpret mixed signals as higher risk and price the naira accordingly.
Domestic inflation and real exchange rate pressures
High domestic inflation reduces the real value of the naira. It makes imports more expensive. Even if nominal interventions limit volatility, they do not lower the real exchange rate on their own. Inflation must be brought under control for that to happen.
4. Data deep dive — turnover reserves and market mechanics
Turnover in the foreign exchange market has expanded since unification reforms. Monthly FX turnover rose appreciably in 2025 reflecting heavier activity in the I&E window and greater participation by authorised dealers. But higher turnover does not automatically mean deeper durable supply. Much of the turnover is intra day or speculative and does not represent fresh non oil earnings.
External reserves are a partial buffer. By late 2025 reserves had recovered strongly compared to the lows suffered earlier in the year. That recovery has allowed larger but selective interventions. The empirical pattern shows that a central bank can smooth volatility. Nonetheless, it cannot change the long run supply demand balance alone.
Exchange rate path
The naira’s depreciation in the prior two years erased real exchange rate gains. It also pushed importers and corporates into defensive mode. Large year on year movements create enormous wealth transfers and fiscal windfalls in some months and heavy losses in others. This volatility further reduces the appetite of long term dollar holders to sell into a fragile market.
5. Case study 1 — Import dependent manufacturing firm in Lagos
A mid sized manufacturer in Lagos sources critical inputs from Asia and invoices in dollars. Before 2023 the firm managed FX risk by transacting in the forward market and using authorised dealers. In 2024 the firm found delivery windows unpredictable and began to access dollars through parallel channels at higher cost.
When the CBN announced a targeted sale to manufacturers the firm secured dollars for one shipment and paused dollar purchases. But the pause was temporary. The real problem was the mismatch between predictable purchase schedules and episodic public sector sales. This mismatch caused the firm to prefer self-insurance.
Outcome
The CBN sale reduced the firm’s immediate cost of imports. But unless the firm can rely on a regular supply through the formal channel it will hedge again. This pattern replicates across sectors and explains why interventions produce short lived relief.
6. Case study 2 — Small trader and the bureau de change
Street level foreign exchange trading remained an accessible source of dollars for many traders. This accessibility persisted despite licence revocations in 2024 and 2025. The recent clean up aims to professionalise the sector. Licensing of 82 authorised bureaux de change under stricter capital rules supports this goal.
Higher capital requirements mean fewer small operators in the short term. There is also an interim vacuum. This vacuum can push activity back into informal corners.
Outcome
The licensing drive is sensible for transparency. But the immediate effect can be to reduce the number of outlets and increase location frictions for buyers. If formal channels do not step in quickly the parallel market will simply find new ways to trade.
7. Case study 3 — Foreign portfolio investor and the sovereign signal
Portfolio flows matter. When sovereign debt markets are attractive and macro indicators look credible foreign portfolio inflows ease pressure on the naira. Conversely when yields fall or policy unpredictability rises those investors reduce exposure.
A surge in inflows helped build reserves in 2025 but these capital flows are fickle. They can reverse sharply on external shocks leading to quick currency depreciation despite earlier interventions. The CBN can only partially offset these reversals with sales.
8. Institutional reactions and political economy
The CBN governor has repeatedly emphasised a willingness to allow market determined rates. He also aims to preserve the role of the central bank in smoothing volatility. Fiscal authorities have welcomed reserve gains but public statements have not always signalled coordinated fiscal consolidation.
International institutions have urged reforms to sustain stability and to tie monetary policy to clearer inflation and fiscal anchors.
The evidence shows a repeating pattern. Interventions stabilise and then fade. They are indispensable in a shallow market. But they are not a substitute for policies that change the fundamentals. The naira falls when supply demand and expectations tilt against it. The central bank can smooth that fall. It cannot prevent it without partners in fiscal policy, trade incentives, and market structures.
The choice is plain. Use interventions while pursuing deep reforms or accept higher long run volatility and the economic pain it brings.
This lack of alignment matters. Markets price the weakest link. If fiscal incentives encourage heavy import demand, currency risk premiums remain high. These premiums also stay elevated if safety nets are insufficient to handle subsidy removal shocks.
9. Why more interventions today may cost more tomorrow
Each reserve sale acts as a temporary cushion. It raises the probability of future constraints if flow fundamentals do not change. Repeated use of reserves without accompanying structural reforms can:
- Weaken shock absorption capacity for larger external events
- Encourage moral hazard where large importers expect periodic public sales rather than market procurement
- Mask necessary adjustment that would rebalance trade patterns and domestic production incentives
At the same time doing nothing is also costly. Unchecked volatility damages households and firms and can trigger inflation spirals and social stress.
10. What success looks like — a practical reform road map
The path to a durable currency stabilisation combines short term management with medium term structural change. Below are pragmatic steps that would reduce the need for repeated interventions
1. Anchor fiscal credibility
Commit to a clear fiscal rule or timetable that narrows the primary deficit. Reduce reliance on reserves to fund recurrent spending. Publish a medium term revenue plan that links oil receipts and non oil measures to spending.
2. Deepen formal dollar supply channels
Make it easier for exporters to repatriate foreign exchange. Offer incentives for diaspora remittances to use formal channels. Expand trade finance and confirmed credit lines for importers to reduce urgent spot demand.
3. Strengthen licensed market makers and BDC capacity
Phase the BDC licensing reforms to preserve access while raising standards. Support consolidation and digital platforms. These platforms connect many small buyers to licensed sellers. They do so without creating friction that pushes trade to the street.
4. Improve policy communication and coordination
The CBN and the ministry of finance should publish a joint FX strategy. Clear signals on when the central bank will intervene and on the fiscal path reduce speculative demand.
5. Tackle inflation and monetary consistency
Bring inflation down incrementally with a credible monetary anchor. Rate moves should be predictable. They should be part of a longer plan to restore real interest parity. This will reduce pass through to the exchange rate.
6. Expand non oil export capacity
Longer term diversification that raises dollars from services and manufacturing is essential. The policy toolkit should include export subsidies that are time bound and monitored to avoid rent seeking.
7. Build market based hedging instruments
Encourage the development of forwards and swaps. Make sure they have transparent clearing. This will allow corporates to hedge. It will also reduce spot pressure.
11. A note on political feasibility
Some reforms are politically hard. Fiscal consolidation and subsidy reform impose near term costs. Licensing changes can be resisted by entrenched networks. That is why sequencing and communications matter.
Pairing reforms with targeted social support and clear timelines can lower political resistance. It can also reduce the temptation to use reserves as a quick fix.
12. Conclusion — interventions buy breathing space not a cure
The evidence shows a repeating pattern. Interventions stabilise and then fade. They are indispensable in a shallow market. But they are not a substitute for policies that change the fundamentals.
The naira falls when supply, demand and expectations tilt against it. The central bank can smooth that fall. Nevertheless, it cannot prevent it without partners in fiscal policy, trade incentives, and market structures.
The choice is plain. Use interventions while pursuing deep reforms or accept higher long run volatility and the economic pain it brings.
