How to Interpret the Consumer Price Index
So how can the Consumer Price Index be interpreted? Here is how to read it. If the Consumer Price Index comes in higher than expected, it means the value and outlook of the dollar are positive; if it comes in lower, it means they are negative. When the value of the dollar rises, stock prices usually fall. On the other hand, when the value of the dollar falls, stock prices rise.
When interpreting the CPI, analysts pay close attention to core CPI, a price index that excludes food and energy. Food and energy have a very large impact on the Consumer Price Index. Not only are their prices highly volatile, but they also serve as signals of cost-push inflation.
In conclusion, many analysts believe that the Consumer Price Index excluding food and energy is the best way to measure the core inflation rate. This is to distinguish demand-pull inflation, which raises the likelihood of a Fed rate hike, from cost-push inflation, which lowers the likelihood of a rate hike.
If core inflation comes in high, it means demand-pull inflationary pressure is building, and the Fed is likely to pursue a tightening policy. On the other hand, if core inflation comes in low, the Fed is likely to continue its quantitative easing policy.
That wraps up our look at the concept of the Consumer Price Index (CPI), how it is measured, and how to interpret it. If you found this post helpful, please give it a heart below. Thank you!
