Is there a difference between "government-bonds" and "treasury" tags?

Question

Description for government-bonds:

for questions that relate to government bonds. It is recommend you use a country tag or state what country you are referring to. A government bond is a bond issued by a national government, generally promising to pay a certain amount on a certain date, as well as periodic interest payments.

treasury has no tag description. Practically all the questions there are about US government bonds. Only one question is specifically about the US Department of the Treasury.

Is there a difference between the "government-bonds" and "treasury" tags? Should they be merged? If not, do you think "treasury" should refer specifically to the US Department of the Treasury?

Answer 1

My only counter-argument is that government-bonds could be about any government's bonds, while treasury is probably specific to the US. I could go for either retagging them as government-bonds and adding a united-states tag, or renaming treasury to treasury-bonds, but that's a subset of government-bonds in my opinion.
