Definition

Market yield on US Treasury securities at 30-year constant maturity, quoted on an investment basis, monthly average of business days, in percent per year (Federal Reserve H.15).

Constant maturity yields are interpolated by the US Treasury from its yield curve. They describe a fixed maturity rather than the return on one particular bond. Values are monthly averages, not month-end quotes.
