Supports: BLS defines CPI as average price change over time for a representative consumer basket and documents its population, scope, reporting conventions, and limits as a cost-of-living measure.

Supports: FOMC statements provide the primary record of policy decisions and show that policy assessment covers a range of information rather than a mechanical response to one CPI release.

Key Takeaways
1
CPI measures average price change for a defined consumer basket, not every household's cost of living or every type of inflation.
2
CPI-U, CPI-W, core, monthly, and annual measures have different definitions and should not be substituted for one another.
3
A published CPI figure, a market expectation, and a policy decision are distinct inputs.
4
CPI data can be research context; it cannot forecast Bitcoin or justify a trade.
Practical Example
A researcher records the BLS CPI release, whether the quoted change is monthly or annual and adjusted or unadjusted, the separate expectation source, and the next FOMC statement. If Bitcoin moves, they document the time window and alternatives rather than attributing the movement to CPI alone.
