HomeLearnInflation: From CPI to Market Impact

Inflation is more than one number

CPI is widely followed, but markets also watch core inflation, producer prices, wage growth and personal-consumption inflation measures. The trend and composition can matter as much as the headline figure.

Actual versus forecast

Markets often react to the difference between the released number and expectations. A high inflation print may create little reaction if it was already expected, while a smaller surprise can matter when positioning is one-sided.
