All Items Less Farm Produce
Before now, “all items less farm produces” is referred to as the Core inflation. This was because the prices of items that constitute energy were regulated by the government e.g, Petroleum Motor Spirit (PMS).

Therefore, Core inflation is referred to as all items index less farm produces and energy.
The “All items less farm produces and energy” or Core inflation, which excludes the prices of volatile agricultural produces and energy stood at 21.84% in September 2023 on a year-onyear basis; up by 4.35% when compared to the 17.49% recorded in September 2022.
