Price Level (CPI)

Think of it this way

It is the supermarket receipt over the years. It does not tell you whether prices rose a lot or a little this month; it tells you how much more expensive everything is compared with when you started working.

What is Price Level (CPI)?

The raw US consumer price index, not converted into a percentage. The statistics office tracks the price of a fixed basket of thousands of goods and services —rent, food, gasoline, insurance, airline tickets— and expresses it as a single number. That number is a comparison, not a price: what the basket cost on average between 1982 and 1984 was assigned the value 100, and everything else is measured against that. So a value of 300 means the same basket costs three times what it did then.

How to read Price Level (CPI)

Three lines of the same index: the raw one, the seasonally adjusted one and core, which excludes energy and food. The adjusted line runs almost on top of the raw one, and it is the one used to calculate the monthly figure. It is the only chart in the block that has to be read as a level, not a slope. It answers the question “how much have prices risen since a given date”. Lag: none; here inflation is the consequence, not the cause.

What Price Level (CPI) means for the market

It is the benchmark against which you measure whether an investment really made money. An asset that rose 20% in five years while this line rose 25% lost purchasing power, even if it shows up in green on the broker's screen. Bitcoin and gold are usually defended by citing precisely this line.

Where the money flows

No money is moving between two parties here: it is the price at which millions of everyday purchases take place. The flow that does matter is the earlier one: the money central banks created ends up, months later, pushing these prices. Example: when a household receives a government transfer and spends it at the supermarket, that purchase competes with all the others for the same quantity of goods, and the price rises.

What to watch in Price Level (CPI)

Do not look for trading signals here, there are none: it is a level that almost never falls. Its value is as context, and as a reminder that inflation does not undo itself. Inflation falling from 9% to 3% does not mean prices go back; it only means they rise more slowly.

The accumulated cost of living. It does not measure liquidity: it measures where the liquidity of previous years ended up.
