WHY would China liquidate their holding of US treasurys all at once? They print all the money they need. What would happen to the price of ANYTHING if a large amount hit the bid?? It would tank the price instantly. That is just one simple reason they will never "call our debt" or "dump it" or any other of these stupid theory ideas. Why would they dump the strongest bonds they own, which are in the strongest global currency? Do you know what bond rates are in europe? The risk rating on those bonds? Look up some of these answers, you`ll get a clue and maybe get off infowars. China is not even the largest holder of US debt!!!
Back to topic, USD will remain kind for quite some time. Which in turn will hurt us exports. NOBODY is buying catapillar right now, they all want komatsu equipment because the YEN is so dang cheap.
