Real vs Technical Inflation: Which Should Guide Monetary Policy in Nigeria?

Why It Matters

Relying on understated technical inflation may cause policymakers to under‑react to household cost‑of‑living crises, deepening inequality and undermining sustainable growth.

Key Takeaways

• CPI rebasing cut headline inflation to 15.15% by Dec 2025.
• Food inflation stayed above 26% despite technical decline.
• CBN’s policy rate remains at 27%, anchored on CPI data.
• IMF warns inflation could hit 16% in 2026.
• Hybrid policy recommended: combine technical data with real‑world signals.

Pulse Analysis

The 2024 CPI rebasing aligns Nigeria’s inflation measurement with international best practices, updating the consumption basket to reflect current spending patterns. By shifting weight away from food and non‑alcoholic beverages toward services such as restaurants and transport, the statistical series shows a sharper disinflation trend. While the methodological overhaul improves comparability across periods, it also creates a statistical illusion: headline inflation appears to have fallen dramatically, even as underlying price pressures, especially for essential goods, remain stubbornly high. Analysts caution that policymakers must understand the distinction between a technical metric and the lived experience of consumers.

Real inflation in Nigeria is driven largely by supply‑side constraints. Food price inflation stayed above 26% after rebasing, fueled by exchange‑rate volatility, agricultural bottlenecks, and security challenges that disrupt supply chains. These factors disproportionately affect low‑income households and micro‑small‑medium enterprises, which together account for nearly half of GDP and almost 88% of employment. The divergence between technical CPI figures and on‑the‑ground price dynamics risks misreading the economy’s health, leading to delayed credit easing or insufficient social protection measures.

For monetary policy, the Central Bank’s 27% policy rate reflects a tight stance anchored to the rebased CPI, yet the IMF’s warning of a possible 16% inflation spike in 2026 underscores the limits of a purely data‑driven approach. A hybrid framework that blends technical inflation data with real‑time market surveys, food‑price indices, and qualitative signals can better calibrate policy levers. Coordinated fiscal actions—targeted transfers, climate‑resilient agriculture, and exchange‑rate management—are essential to address supply‑side shocks. By marrying statistical rigor with ground‑level realities, Nigeria can navigate the inflation‑growth trade‑off while protecting household welfare.
