Introduction

Nigeria's inflation trajectory in September 2026 showed significant cooling, with the headline rate declining from the previous month's print. The National Bureau of Statistics reported a notable slowdown driven by easing cost pressures in key categories, even as some segments continued to show underlying strength.

What Happened

The Consumer Price Index slipped to 146.38 points from 146.30 points in August, reflecting a modest monthly shift. Headline inflation fell to 14.63 percent in September, down from 15.39 percent in August, representing a year-on-year decrease of 6.35 percentage points. Month-on-month, the headline rate dropped sharply to 0.06 percent from 0.71 percent in the prior period. Food inflation moderated to 19.59 percent year-on-year, down from 20.16 percent in the same period of 2025, and turned negative on a monthly basis, declining to -1.55 percent from 1.02 percent. Core inflation, however, moved higher, rising to 1.11 percent month-on-month from -0.06 percent in August, and stood at 12.95 percent year-on-year, down from 22.11 percent in September 2025.

Why This Matters

The divergence between falling food prices and rising core inflation indicates that the overall cooling is not evenly distributed across the consumer basket. Urban inflation remained elevated at 15.64 percent year-on-year, while rural inflation eased to 12.46 percent. State-level data revealed wide gaps, with Imo recording the highest year-on-year headline rate at 30.04 percent and Taraba the lowest at 1.78 percent. Month-on-month figures also varied significantly, as Imo posted 8.64 percent while Adamawa recorded a steep decline of -6.10 percent. These disparities highlight the uneven impact of price changes across regions and households.

Key Takeaways

  • Headline inflation cooled to 14.63 percent in September, the lowest level in several months.
  • Food price moderation was the primary driver, with year-on-year rates dropping and monthly figures turning negative.
  • Core inflation accelerated month-on-month, signaling that not all price pressures have eased.
  • Urban and rural inflation experiences diverged, with urban areas facing higher sustained rates.
  • State-level gaps remain pronounced, from 30.04 percent in Imo to 1.78 percent in Taraba.
  • Monthly trends show significant regional variation, with some states recording declines and others sharp increases.

Conclusion

The September inflation report presents a mixed picture of progress and persistent pressure. While the drop in headline figures and the monthly decline in food costs provide welcome relief, the acceleration in core inflation and wide state-level gaps underscore that the cost-of-living challenge remains complex. Continued monitoring of price trends and targeted policy responses will be essential to ensure that the current moderation translates into broader economic stability.
