Core Inflation
Inflation excluding food and fuel, whose prices are volatile and driven largely by supply conditions.
Formula
Core Inflation = Headline Inflation computed on the basket excluding food and fuel components

In depth
Core inflation is watched by central banks because monetary policy cannot influence a failed monsoon or a crude price spike, but it can influence the persistent, demand-driven component. Excluding food is analytically defensible and politically awkward in India, where food is nearly half the basket and most of what households actually experience. Core inflation is stickier than headline, so it falls more slowly and signals whether a price shock has fed into wages and general prices. Divergence between the two is informative: headline above core is a supply shock, core above headline suggests broad demand pressure.
Worked example
Headline inflation at 7.1% with core at 4.6% points to food and fuel driving the gap. Six months later the same food shock has passed and headline may fall below core without any policy change.
