TNX 10 year treasury note : Monthly ~

Interesting ~ downtrend of 10Y T Notes. The reason of this decline, of course, lesser and lesser demand for bond trading.

All the same: T-Bill == 1 Year Maturity or less,
T-Note == 1~10 Years Maturity
T-Bond == 10-30 Years Maturity
naming different? Duration must have been very important to call it differently to distinguish -
