On the other hand, "core inflation" (also non-food-manufacturing or underlying inflation) is calculated from a consumer price index minus the volatile food and energy components. [1] Headline inflation may not present an accurate picture of an economy's inflationary trend since sector-specific inflationary spikes are unlikely to persist.
On a "core" basis, which strips out food and energy prices, CPI is forecast to have risen 3.2% over last year in September, unchanged from August. Monthly core price increases are expected to ...
