Frequently asked questions

What is CPI?

The Consumer Price Index measures how the prices of a basket of goods and services bought by US households change. The year-on-year change is what is usually quoted as inflation. It is published by the US Bureau of Labor Statistics around the 10th to 15th of the month.

What is core inflation?

Inflation excluding food and energy prices, which swing strongly. It shows more persistent price pressure, which is why the Fed watches it more closely than the headline number.

Why does inflation matter for crypto and stocks?

High inflation forces the Fed to keep rates high or raise them, which weighs on the valuation of stocks and cryptocurrencies. Surprisingly low inflation, on the other hand, raises hopes of rate cuts and markets typically rise.

What is the inflation target?

The Fed targets 2% average inflation as measured by the PCE index. Headline CPI tends to run slightly higher than PCE.
