Mr. Mosler and his MMT theory are doing their best Sheen impersonation. The below excerpt from a well-known bond trader demonstrates that Warren's ideas are percolating among the decision-makers of the world. Readers here will note the similarities.
2. MYTHS REGARDING FOREIGN INVESTORS FUNDING THE UNITED STATES AND EXTERNAL LIABILITIES:
Firstly, the most important item to understand is the USA discharges its
debt in $US. So the entire argument of rating agencies behind ‘external
funding pressures’ is moot. Functionally there is no difference between a
holder of UST’s who is domiciled in USA or abroad, as they are both $US
dominated savers. The only difference is the foreign saver has no ‘need’ to
save in $US (where a USA investors needs $US as a means of exchange and to
pay his taxes).
So, what if foreign now dump their ust’s?
Foreign investors own ust’s and $us because they WANT to own them. By
engaging in fx driven trade policies, foreigners ‘pay up’ to get $US which
allows them greater sales into the USA market. If foreigners didn’t want to
save in $US, they would change their fx policy which would result in less
market share in USA economy. Foreigners can’t be both buyers and sellers
simultaneously. If foreigners wanted to own less $US, the result would be a
smaller current account deficit in USA, which again using a financial
balance framework would either result in more private savings, or a smaller
govt deficit. Bottom line – if foreigners want to have fewer savings in $US,
either private savers must increase savings, or the govt deficit must fall.
3. MYTHS REGARDING FOREIGN INVESTORS FUNDING THE UNITED STATES AND EXTERNAL LIABILITIES part II:
The same way banks offer savers demand deposits and term deposits (ie
chequing accounts versus savings accounts) the USA economy offers savers the
same in the form of $US (demand assets) or UST (term asset). Foreign savers
can therefore keep their $ at their Fed Reserve account and earn basically
zero (functionally a ‘chequing’ or demand account) or buy UST’s
(functionally a ’savings’ or term account) and earn a coupon. There is no
other way to save in risk free space. As said above, foreigners who engage
in fx driven trade policies must accumulate $US demoninated assets. The only
choice they have is term vs demand assets. So indeed if foreigners declined
to own ust’s and alternatively kept their savings in $US at the Fed, the
result could be a higher and steeper term structure for USA rates. If the
Treasury decided to sell less ust’s and more tbills, this term structure
rise could be negated. Note foreigners actions are never about SOLVENCY, its
merely a function of liquidity preference.
