Economy & context
Inflation is a sustained rise in a broad measure of prices, reducing the purchasing power of a unit of money. Different households and businesses experience different price baskets.

If the prices of many basket items rise while the number of pounds stays fixed, fewer items fit. One dear product alone is not the same as broad inflation.
Now put that into markets
Statistical agencies track representative baskets and publish price indices. Markets respond to inflation itself and to how it differs from expectations.
Headline, core, goods and services measures isolate different components. Base effects and weights can change annual rates even when current prices move modestly.
Check index, geography, period, annual or monthly rate and revisions. Compare level changes with the rate of change.
A national average is not a personal cost-of-living measure, and lower inflation means slower price growth rather than generally falling prices.
