CPI
MARKETSDEFINITION
The Consumer Price Index — the US government's main measure of inflation, tracking the change in prices for a fixed basket of consumer goods and services over time. Released monthly by the Bureau of Labor Statistics.
CPI measures how much prices for everyday items — food, housing, energy, medical care — have changed since a prior period. "Headline" CPI includes everything; "core" CPI strips out food and energy, which swing on their own and can obscure the underlying trend the Fed actually cares about.
CPI is the single input the FOMC weighs most heavily when deciding whether to cut, hold, or raise interest rates. A hotter-than-expected print makes a rate cut less likely and often firmer for longer; a cooler print does the opposite. Because the report lands on a fixed monthly schedule, it's one of the most reliably market-moving releases on the calendar.
For bitcoin, CPI matters indirectly but powerfully: it's an input into the rate decisions that drive bitcoin's price as a long-duration risk asset. Traders often position ahead of the release and unwind quickly once the number prints, producing some of the sharpest short-term volatility in crypto markets.
IN A SENTENCE
"Bitcoin trimmed gains ahead of Tuesday's CPI print, with traders reluctant to add risk before the number."
Key facts
Common questions
Why does bitcoin react to CPI?
CPI is the Fed's main inflation gauge, and it directly shapes whether the FOMC cuts, holds, or raises rates. Since bitcoin trades as a long-duration risk asset, the rate path CPI informs is one of the biggest external forces on its price.
What's the difference between headline and core CPI?
Headline CPI includes every category; core CPI excludes food and energy, which are volatile on their own. The Fed leans more on core CPI to gauge the underlying inflation trend.
