Do you know what happens when 2 trillion dollars worth of bills get dumped? US depended on Saudi oil to maintain USD$ value and in return they used their military to maintain USd$ dominance. I am not saying the system will implode but the effects of that plus the second largest economy withdrawing from this US dollar based system would be dissatrous. US is worried China trading directly converting currency directly, they know once that happens, alot of country would be free. You seem to like to cheer for this colonial system. Talking like a loyal slave. Ask China why they dare to defy US, other than us nobody can compete and rival US.
2 Trillion is too large an amount to be dumped.
The T-bills you hold do not even generate any interest. So you are already at a loss holding them, but to dump them will wipe out a significant part of your foreign currency savings. US loss might be short term, yours will be long term.
If the US puts a sanction on you for attempting to dump the USD, who do you think the world will stand behind ?
Maybe Russia will stand behind china. Who else ? How else will you purchase non russian oil and gas ?
Stating the truth and Facts is not cheering the system. Neither is your boasting going to change the reality.
You are talking like a foolish ignorant nationalist attempting to punch beyond your weight so don't be surprised when the world tells you that you will fail. Thank fully your govt. knows this.
