For the benefit of anyone else reading this, I'd like to point out the misconceptions and misinformation above.
> China can 'starve' any nation to the extent they are a lender to that nation. China's demand for Treasuries makes up part of the demand curve for Treasuries, along with all the the demand.
The Federal Reserve controls short term yields completely through its open market operations desk. It controls long term yields as well, because they are a function of expectations of short term yields. If China, or Russia, or anyone else stops buying treasuries, the Primary Dealers will pick up the slack, and they will always take that deal because no matter what the yields are they make money off it.
> If China was the only buyer of US Treasuries you can dam well be sure they can 'starve the Treasury' - because if nobody is buying Treasuries, then the government is printing money.
The Federal Reserve, not China, creates reserves every time the Treasury or a member bank asks it to, which is all the time. It's called an elastic money supply. Relatively few reserve notes are actually printed, because there isn't a lot of demand for Federal Reserve Notes compared to demand accounts.
>Every nation on Earth can do this. It's called 'printing money'. It's not a new idea, and it has dramatic consequences including hyperinflation.
Hyperinflation is a consequence of a collapse in productivity, not of money printing. Some governments turn to printing more money as their money becomes worthless, and there is a feedback loop, but that is a consequence not a cause. Hyperinflation can also occur when the money issuing sovereign effectively loses their sovereignty, fully or partially.
> China is the #1 lender to the US both in Treasuries (and by holding US dollars.)
The Federal Reserve is the USA's bank, not China. China is just another depositor at the Fed and whether they choose to store their capital account surplus with the USA in a interest free account (reserves) or an interest bearing account (treasuries) is irrelevant to the solvency of the US Treasury.
I hope this helped everyone else with an interest in understanding some of the widespread ideologically motivated ("money printing" is a shibboleth) misconceptions in this area.
