The Treasury publishes a par yield curve on business days. Each point is a yield for a maturity. You can read it the way you read a posted price: this is what the market paid, that day, for that length of government debt.
You do not have to do anything with it. A household might look at the three-month yield and the ten-year yield to understand the difference between parking cash and locking money away. Looking is not a transaction. The column that turns every curve update into a command to buy has changed genres.
