Us CPI Data
In short
The Consumer Price Index (CPI) data measures the average change over time in the prices paid by consumers for a basket of goods and services. It serves as the primary indicator for inflation in the United States.
In plain words
It tracks how much more expensive everyday things like food, fuel, and rent become. When the CPI goes up, your money does not buy as much as it used to. This change is called inflation.
A simple example
If a loaf of bread costs £1.00 this year and £1.05 next year, the CPI helps calculate that price increase. This shows how much more expensive living has become.
Why it matters
Central banks use this data to decide whether to raise or lower interest rates. Higher inflation often leads to higher interest rates to cool down the economy.
Easy to mix up
Do not confuse CPI with PPI (Producer Price Index), which measures price changes from the perspective of manufacturers rather than shoppers.
