Nigeria’s inflation rate ticked up in May, as stubborn price pressures in Africa’s 4th-largest economy fail to cool down, complicating expectations that policymakers could soon pivot toward lower interest rates.
Data released by the National Bureau of Statistics (NBS) showed headline inflation rose to 15.93% in May 2026 from 15.69% in April, marking a reversal after months of moderation. While the increase was relatively modest, it underpins the struggle of the Bola Tinubu-led government to make the impact of its economic reforms reflect on the cost of living of Nigerians.
The Consumer Price Index (CPI), which measures the average change in prices of goods and services, climbed to 140.7 points in May from 138.3 points in April, reflecting continued increases in the cost of living for households and operating costs for businesses.

A closer look at the figures, however, suggests the inflation story is becoming more nuanced. The month-on-month inflation rate slowed to 1.75% in May from 2.13% in April, indicating that while prices are still rising, the pace of those increases is easing.
The divergence between annual and monthly inflation readings suggests that Nigeria remains caught between lingering structural inflationary pressures and emerging signs of stabilization.
Food Prices Remain Elevated
Food inflation, one of the most closely watched indicators given its direct impact on household welfare, stood at 16.96% year-on-year in May. Although still high, the figure represents a significant decline from 24.55% recorded in May 2025.
Monthly, food inflation eased to 2.98% from 3.63% in April. According to the NBS, movements in food prices were driven by changes in the cost of staple items, including fresh onions, maize, tomatoes, fresh pepper, cassava flour, wheat grain, yam tubers, sweet potatoes, plantain, ginger, cowpea, crayfish, water yam, and egusi.
The moderation in food inflation may offer some relief after years of severe food-price shocks that eroded purchasing power and worsened poverty levels across the country.
Yet market evidence suggests consumers are still struggling. Recent surveys of major Lagos markets showed food prices increased again in May after broad-based declines in April, indicating that the impact of lower inflation rates has yet to translate into meaningful affordability improvements for many Nigerians.
Economists have repeatedly noted that a decline in inflation does not mean prices are falling. Rather, it means prices are rising at a slower pace. For households already coping with years of cumulative price increases, the cost of food and essential services remains historically high.
Urban-Rural Divide Widens
The latest data also revealed differing inflation dynamics between urban and rural areas. Urban inflation rose to 16.07% year-on-year, while the monthly urban inflation rate increased slightly to 1.99% from 1.86% in April.
Rural inflation came in at 15.60% year-on-year. More notably, monthly rural inflation slowed sharply to 1.17% from 2.80% in April.
The sharp moderation in rural inflation may indicate some easing of supply-side pressures in agricultural communities, although urban centers continue to experience stronger price increases driven by transportation, housing, and service-related costs.
Core Inflation Remains Stubborn
One area likely to attract the attention of policymakers is core inflation, which excludes volatile agricultural produce and energy prices. Core inflation rose to 16.82% year-on-year, while monthly core inflation accelerated to 1.94% from 1.03% in April.
The increase suggests underlying inflationary pressures remain embedded within the economy even as food inflation gradually moderates.
For the Central Bank of Nigeria (CBN), core inflation is often viewed as a more reliable gauge of persistent price pressures because it filters out temporary shocks associated with food supply disruptions and energy price volatility. The uptick in core inflation may strengthen the argument for maintaining a tight monetary stance despite calls from some economists and businesses for lower borrowing costs.
External Pressures Returning
The May inflation figures come against a backdrop of renewed global uncertainty following escalating geopolitical tensions in the Middle East.
The World Bank Energy Index rose to 146.4 points from 130.6 points, reflecting higher energy costs globally. Similarly, the Food and Agriculture Organization’s Food Price Index climbed 1.6% to 130.7 points, marking its third consecutive monthly increase.
These developments raise concerns about imported inflation, particularly for a country heavily dependent on imported refined petroleum products, industrial inputs, and food-related commodities. Higher global energy costs could eventually feed into transportation expenses, logistics costs, and manufacturing operations, creating fresh inflationary pressures across the economy.
Signs of Progress Remain
While the latest monthly increase in headline inflation may generate concern, broader trend indicators show notable improvement compared with a year ago.
The average annual food inflation rate for the 12 months ending May 2026 fell to 16.99%, down sharply from 33.21% recorded during the corresponding period in 2025.
Average urban inflation moderated to 18.27% from 32.55% a year earlier, while average rural inflation declined to 18.19% from 28.36%.
Core inflation’s 12-month average also eased significantly to 19.59% from 27.05%.
These figures suggest that the broader disinflation process remains intact even though monthly data show occasional setbacks.
What It Means For Interest Rates
The inflation report arrives at a crucial time for monetary policy. In recent months, some economists have argued that consecutive declines in inflation created room for the CBN to consider reducing the Monetary Policy Rate (MPR) to support economic growth and lower borrowing costs.
The latest increase in headline inflation may complicate that debate. Although monthly inflation slowed, the return of annual inflation growth and the acceleration in core inflation could make policymakers more cautious about easing monetary conditions too soon.
The challenge for the CBN is balancing inflation control against the need to stimulate economic activity in an environment where businesses continue to face high financing costs, and consumers remain under pressure.
For ordinary Nigerians, the key issue remains whether inflation moderation will eventually translate into lower prices at markets and reduced living costs. So far, many consumers say they have yet to feel meaningful relief, even as official inflation indicators show gradual improvement.
The May data suggest the battle against inflation is moving in the right direction, but it is far from over. Persistent food costs, rising core inflation, and renewed global commodity risks mean policymakers may need to maintain vigilance even as broader inflation trends continue to improve from the extreme levels seen a year ago.
