Core Inflation
Definition
A measure of inflation that excludes volatile food and energy prices to reveal the underlying trend in price changes driven by demand, rather than temporary supply disruptions.
Simple Explanation
Regular CPI includes everything — food, fuel, everything. But food and energy prices jump around wildly due to droughts, floods, oil crises, and seasonal patterns that have nothing to do with the general health of the economy. Core inflation strips these out. If core inflation is high, it means inflation is broad-based and driven by strong demand — the central bank needs to act. If headline CPI is high but core is low, it may just be a temporary food supply shock.
In Pakistan
Pakistan's central bank (SBP) uses 'Non-Food, Non-Energy (NFNE)' CPI as its core inflation measure. During the 2022–2023 crisis, both headline CPI (38%) and core CPI (25%+) were high — signalling that inflation had become broad-based, not just a food/energy shock. This gave the SBP stronger justification for aggressive rate hikes. By contrast, if only headline were high while core stayed low, the SBP might have been more patient.
Example
If headline CPI is 25% but NFNE core CPI is 12%, the gap (13pp) is driven largely by food and energy. The SBP might tolerate this and wait for supply conditions to normalise. But if core CPI rises to 20%, the SBP would likely hike rates aggressively because inflation has spread beyond food and energy into services, manufacturing, and wages.
Frequently Asked Questions
Does removing food prices from core inflation mean it's not relevant to poor households?
Exactly the opposite concern is valid: core CPI is less relevant to poor households precisely because food is excluded. Poor Pakistani households spend 50–60% of income on food — so food prices matter enormously to their effective inflation rate. Core CPI is a technical monetary policy tool, not a welfare measure. For household welfare analysis, headline CPI (and specifically the food sub-index) is more relevant.
