Abstract
Recent macroeconomic data in Nigeria reveal a decoupling between headline inflation, which shows signs of moderation, and food inflation, which remains elevated. This divergence presents a critical challenge for monetary policymakers and calls for a nuanced understanding of inflation drivers in Nigeria. While monetary tightening by the Central Bank of Nigeria (CBN) has contributed to the decline in headline inflation, food inflation persists due to structural inefficiencies, supply chain disruptions, and cost-push pressures. This paper investigates the factors behind these diverging inflation trends and provides a forward-looking projection of the next Monetary Policy Committee (MPC) decisions with respect to the Monetary Policy Rate (MPR), asymmetric corridor, Cash Reserve Ratio (CRR), and Liquidity Ratio (LR).
1. Introduction
Inflation is a central concern for emerging market economies, especially where price instability directly impacts real income, food security, and macroeconomic confidence. In Nigeria, inflationary dynamics have been particularly complex. While headline inflation declined slightly to 22.22% in June 2025, food inflation remains alarmingly high, well above 30%, threatening social stability and economic progress.
This paper seeks to examine the reasons behind this dichotomy and assess how the Central Bank of Nigeria (CBN) is likely to respond in its next Monetary Policy Committee (MPC) meeting. The central question is: why is headline inflation falling while food inflation continues to rise? And what are the implications for monetary policy?
2. Inflation in Nigeria: Disaggregating the Indicators
2.1 Headline Inflation
Headline inflation measures the general change in the price level of all goods and services in an economy. It includes both volatile components (like food and energy) and core components (like services, rent, education, etc.). As a broad measure, it serves as the main indicator of inflation trends.
2.2 Food Inflation
Food inflation, a subcomponent of the Consumer Price Index (CPI), captures changes in the price of food items such as cereals, meat, oils, vegetables, dairy, and beverages. In Nigeria, food accounts for over 50% of the CPI basket, making it both a key driver and a lagging influence on headline inflation.
2.3 Recent Trends
- Headline Inflation (June 2025): 22.22%
- Food Inflation (June 2025): ~30–33%
- Core Inflation: Significantly lower than food inflation, due to reduced imported inflation and tight monetary conditions.
The data indicates that non-food components are decelerating, largely due to tighter liquidity, but food-related costs remain resistant to downward pressures.
3. Why Is Headline Inflation Declining?
3.1. Aggressive Monetary Tightening by the CBN
The Central Bank has pursued one of the most aggressive tightening cycles in its history. Since 2023, the Monetary Policy Rate (MPR) has been raised multiple times, reaching 27.50% as of the last MPC. In parallel, the Cash Reserve Ratio (CRR) has been raised to 50%, and the asymmetric corridor adjusted to +500/-100 basis points. These tools have:
- Curbed excessive liquidity in the financial system.
- Increased the cost of borrowing, reducing credit-fueled demand.
- Helped anchor inflation expectations.
- Encouraged foreign portfolio inflows that supported exchange rate stability.
3.2. Stabilization of the Exchange Rate
The foreign exchange market has experienced partial stabilization due to:
- Improved FX supply from autonomous sources.
- Reduction in CBN backlog obligations.
- Diaspora remittances.
- Slower speculative demand for USD.
The relative stability in the naira-dollar exchange rate has reduced the imported inflation pass-through, especially for non-food imports like electronics, vehicles, and raw materials.
3.3. Base Effects
High inflation in the base year (2024) due to fuel subsidy removal, exchange rate unification, and fiscal reforms means that year-on-year inflation rates now appear to moderate even if prices remain elevated.
- Why Is Food Inflation Still Rising?
4.1. Structural Insecurity in Food-Producing Regions
A key contributor to rising food prices is rural insecurity, especially in the North-East, North-West, and parts of the Middle Belt. Farmer-herder clashes, banditry, and kidnapping have forced many farmers to abandon agricultural production, reducing food output and increasing scarcity.
4.2. High Agricultural Input Costs
Despite FX rate stability, fertilizers, herbicides, pesticides, and farming equipment remain costly due to:
- Global supply chain disruptions.
- High import dependency.
- Transportation bottlenecks.
For instance, a 50kg bag of fertilizer now costs over ₦45,000, up from ₦18,000 two years ago. This raises the cost per hectare of production, which is passed on to consumers.
4.3. High Transportation and Logistics Costs
Fuel prices, driven by deregulated PMS pricing, now exceed ₦800–₦1,000 per litre in many parts of Nigeria. This disproportionately affects the food sector, as perishable goods require quick and safe transportation, often across long distances with poor road infrastructure.
4.4. Lean Season and Climate Challenges
From May to August, Nigeria enters the lean season, when stocks from the previous harvest are depleted and new crops are not yet ready. Additionally, irregular rainfall and climate-related flooding have damaged yields, especially in rice, maize, and vegetable farming.
4.5. Weak Storage and Distribution Systems
Post-harvest losses in Nigeria are estimated to exceed 30% due to poor warehousing, lack of cold chains, and inadequate market infrastructure. This exacerbates the mismatch between supply and demand, especially in urban areas.
5. MPC Decision in Hindsight: A Strategic Pause Amid Persistent Inflation
Following the publication of this analysis, the Central Bank of Nigeria’s Monetary Policy Committee (MPC) convened and resolved to maintain all existing monetary parameters. This decision confirmed the forecasted trajectory, and in hindsight, reflects a calculated move to observe the lagging effects of aggressive monetary tightening already undertaken.
- The MPC held the Monetary Policy Rate (MPR) steady at 27.50%, retained the Cash Reserve Ratio (CRR) at 50%, maintained the asymmetric corridor at +500/-100 basis points, and left the Liquidity Ratio unchanged at 30%.
- This unanimous hold signals a pause-and-assess stance, which carries several implications for the broader economy.
-
5.1. Monetary Policy Rate (MPR) Held at 27.50%
- By leaving the MPR unchanged, the CBN has signaled that it is confident in the disinflationary trend of headline inflation, but remains cautious about overtightening, especially given weak real sector growth and persistently high lending rates. The MPC appears to be allowing time for the effects of earlier hikes—cumulatively over 750 basis points since 2023—to filter through the economy.
- Implication: The hold provides relief to interest-sensitive sectors such as manufacturing and small businesses, preventing further contraction in credit availability. However, it also implies that inflation, especially food-driven, will continue to be influenced more by non-monetary variables.
-
5.2. Asymmetric Corridor Retained at +500/-100bps
- This wide corridor remains a tool for tight liquidity management without a headline rate hike. It allows the CBN to discourage frequent borrowing at the Standing Lending Facility while absorbing liquidity at a steep discount via the Standing Deposit Facility.
- Implication:This helps sterilize excess liquidity in the banking system subtly while avoiding shocks to investor sentiment. It reinforces a tight stance while keeping monetary operations flexible.
-
5.3. Cash Reserve Ratio (CRR) Maintained at 50%
- Despite calls from the banking industry to reduce the CRR burden, the CBN retained thevery high CRR of 50%, continuing its policy of aggressive liquidity sterilization through mandatory reserves.
- Implication:This decision reflects the CBN’s continued focus on inflation containment, even at the expense of bank profitability and private sector credit expansion. Banks will likely remain cautious in lending, particularly to high-risk sectors.
-
5.4. Liquidity Ratio Maintained at 30%
- This prudential ratio, which ensures banks maintain a buffer of liquid assets, was kept unchanged. Given the already constrained liquidity landscape, any tightening here would have created unnecessary strain.
- Implication:The stable liquidity ratio ensures that systemic liquidity remains adequate, especially in the face of heightened CRR constraints and volatile capital flows.
6. Broader Policy Implications
The Central Bank of Nigeria’s decision to maintain all key monetary policy tools, MPR at 27.50%, CRR at 50%, asymmetric corridor at +500/-100bps, and liquidity ratio at 30%, is a clear signal that the apex bank believes its current level of monetary tightening is adequate for now. However, the continued rise in food inflation suggests that the scope of monetary policy alone is insufficient to achieve full price stability.
This reinforces a fundamental truth: Nigeria’s inflation problem is now largely structural, and correcting it requires a multi-agency, cross-sectoral policy response. While monetary tools are effective in managing exchange rate volatility, aggregate demand, and speculative pressures, they are ill-suited for resolving issues such as insecurity in farming regions, inadequate rural infrastructure, and inefficiencies in food distribution.
The current environment calls for a shift in the burden of adjustment, from monetary to fiscal and sectoral reforms. The implications are as follows:
6.1. Rebalancing the Inflation Fight Toward Structural Solutions
Monetary policy has reached a point of diminishing returns. Further tightening would risk damaging credit creation and investment, particularly among SMEs. Instead, greater effort must now go into addressing the non-monetary drivers of inflation, such as:
- Rural insecurity,
- Post-harvest losses,
- Fuel-driven transport costs,
- Poor input affordability and availability.
These areas lie within the domain of fiscal policy, agricultural reform, and public investment.
6.2. Fiscal Coordination Must Intensify
The effectiveness of the CBN’s tight stance depends on whether fiscal authorities can intervene directly in the food supply chain. Coordinated investments in agricultural extension services, rural roads, irrigation, and market systems will relieve supply-side constraints that are immune to interest rate changes.
Without such fiscal support, the pressure to overextend monetary tools will persist, with negative consequences for credit, investment, and employment.
6.3. De-risking the Agricultural Sector
A critical implication of rising food inflation is the need to de-risk agriculture, both for producers and lenders. The government must support:
- Agricultural insurance schemes,
- Expansion of the Anchor Borrowers’ Programme in a more transparent and scalable form,
- Public-private partnerships to deliver mechanization and storage infrastructure.
By lowering risk, such measures can encourage private capital inflows into the sector and improve productivity.
6.4. Macroprudential Trade-offs for the Banking Sector
The sustained high CRR of 50% continues to constrain banking sector liquidity, with implications for credit to the real economy. While it supports disinflation, it also:
- Reduces net interest margins,
- Limits banks’ ability to finance SMEs and agribusinesses,
- May lead to informal lending channels at higher costs.
A tiered or targeted liquidity framework that incentivizes lending to priority sectors could improve the transmission of monetary policy without undermining macro stability.
6.5. Restoring Public Confidence and Market Anchoring
Finally, maintaining current rates signals policy consistency and discipline, which is vital for anchoring inflation expectations. However, sustained inflation, especially food inflation, can quickly erode public confidence if not addressed through visible improvements in supply and affordability.
This implies that the credibility of the CBN and broader macroeconomic management now hinges less on rate changes and more on inter-agency policy coherence
7. Conclusion
Nigeria’s current inflation profile reflects a classic case of demand-management tools being used to fight a supply-side problem. While tight monetary policy has contributed to a moderation in headline inflation, it has limited effect on food prices driven by security, logistics, and productivity challenges.
The next MPC is likely to hold the current monetary stance steady, while encouraging fiscal actors to address food supply challenges more directly. Until structural constraints are tackled, food inflation will remain a persistent threat to macroeconomic stability and human development.
8. Recommendations
High Food Inflation
Establish agro-security corridors and food transport protection systems to ensure safe access to farmlands and secure distribution of produce across the country.
Inadequate Input Access
Reintroduce targeted subsidies for critical agricultural inputs such as fertilizers, seeds, and mechanization services. Support domestic manufacturing of inputs to reduce dependence on imports and foreign exchange volatility.
Post-Harvest Losses
Invest in cold storage infrastructure, grain silos, and regional logistics hubs to minimize spoilage and improve food preservation from farm to market.
Monetary Policy Effectiveness
Recognize the limitations of interest rate tightening and complement it with fiscal interventions aimed at boosting food production and reducing structural bottlenecks in the supply chain.
CRR Impact on Banks
Consider adopting a tiered Cash Reserve Ratio (CRR) structure that offers relief to small and mid-sized banks, encouraging more credit flow to the real sector without undermining the CBN’s liquidity management objectives.
