The month-on-month CPI change for United States isolates price momentum in a single calendar month, stripping away base effects that can distort the year-on-year figure. It is released alongside the headline year-on-year CPI by the national statistics agency.
Why FX traders watch it
Month-on-month CPI provides an early read on whether inflationary pressure is building or easing in real time. The Federal Reserve watches sequential monthly prints closely when deciding whether annual inflation is on a sustained trajectory toward target.
How to interpret the data
A positive monthly print above expectations signals re-acceleration of inflation and is usd-supportive. A negative or flat reading suggests softening and may shift rate-path expectations to the dovish side.
Optional upper bound. Defaults to the current date.

Frequently Asked Questions
Why use month-on-month CPI instead of year-on-year?
Year-on-year figures contain base effects from the same month the previous year. Month-on-month removes that distortion, making it easier to identify turning points in inflation momentum.
