The USA has just passed a US$1.3T spending bill.

Here we go again!  The USA will issue more government bonds to fund this newly passed $1.3T spending bill but it won't be easy to attract foreign central banks and investors to buy US treasuries this time.  Why?

This is because the USA has rankled many countries with its upcoming global trade war.  This global trade war will affect many economies and induce slower economic growth.  When other government coffers and investors are badly affected, they won't purchase more US treasuries.

The USA really has a warped logic!
