I notice that here the current yields of different treasuries are reported each day. However, are there multiple maturity dates for each security with probably different yields?
For example, consider a 10 year note issued in 2015 and a 10 year note issued last month. The yields of these two may be different based on their prices, but yet a single yield is reported.
- How is this single yield number computed? Does it just take the most recently issued 10 year note?
- Are there data sources which split the 10 year notes by maturity date?
