Decoupled Inflation: Why Food Prices Defy Nigeria’s Monetary Tightening
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

CBN Retains MPR at 27.5% to Sustain Disinflationary Trend
The Central Bank of Nigeria (CBN) has announced the retention of the Monetary Policy Rate (MPR) at 27.5% following the conclusion of its 301st Monetary Policy Committee (MPC) meeting held on Tuesday, July 22, 2025. Addressing journalists after the meeting, CBN Governor Dr. Olayemi Cardoso stated that the committee’s decision was driven by the need to sustain the disinflationary trend and contain price pressures in the economy. “The decision was premised on the need to sustain disinflation and sufficiently contain price pressure,” Cardoso explained, noting the committee’s cautious optimism about recent economic indicators. All 12 MPC members voted unanimously to maintain the MPR at 27.5%, signaling a unified stance among policymakers amid persistent inflationary pressures and exchange rate volatility. The MPR, which serves as the benchmark interest rate, remains a critical tool in the apex bank’s efforts to rein in inflation, which, although slowing in recent months, is still above the CBN’s target range. Key decisions from the MPC meeting include: Retention of MPR at 27.5% Maintenance of the asymmetric corridor around the MPR at +500/-100 basis points Retention of Cash Reserve Ratio (CRR) at 50% for Deposit Money Banks and 16% for Merchant Banks Maintenance of the Liquidity Ratio at 30% Governor Cardoso emphasised that the current policy stance would continue to address both existing and emerging inflationary pressures. “The MPC will continue to undertake rigorous assessments of economic conditions, price developments, and outlook to inform future policy decisions,” he said. Analysts were divided ahead of the meeting, with some expecting a marginal rate hike to strengthen the naira and others predicting a hold decision due to concerns over sluggish economic growth. The decision to maintain rates reflects the CBN’s focus on balancing inflation control with economic stability as businesses and consumers navigate a challenging macroeconomic environment. Other potential adjustments to the CRR or Liquidity Ratio were not immediately disclosed at the time of the announcement. Overall, the unanimous vote underlines the Bank’s commitment to monitoring the effectiveness of current policies before making further adjustments, amid growing concerns about the trajectory of the economy if inflation remains unchecked.
