US Treasury

30-year Treasury

A constant-maturity yield: the Treasury's own interpolation of what a security of exactly this maturity would yield, published daily. It is not the price of any particular bond you could buy.

A published rate series is a number somebody else measures and releases on a schedule: an official calculation, a survey of lenders, or an average across many institutions. It is not a price you can trade at, and it is not an offer: no bank, broker or issuer has to give anyone the figure on this page. The date beside the value is the day the publisher observed it, not today, and the number stays exactly as released until the next observation appears. Read it as a reference point for what this kind of borrowing or lending cost on that date, and nothing more.

Each row is one observation, exactly as it was published. How often rows appear is the publisher's own schedule (daily, weekly, monthly or quarterly), so a short list is not a rate that stopped moving, and a gap is usually a holiday or a series that simply reports less often. Nothing is filled in between the rows.

Rates are published by third parties and are shown as published. They are reference figures for research, not offers: no bank, broker or issuer is obliged to transact with anyone at a rate shown here.
