I hope we don’t end up with Zimbabwe inflation. I understand dollar value to be measured against a basket of currencies, but the dollar isn’t the only currency declining, and countries have been offloading their US dollar reserves for some time, and as far as I aware the printing presses have been whirring for some time, so nothing new there. The dollar may not remain the dominant currency, but much smaller currencies have survived economic turmoil. China is driven by an export market, and depends on US for imports, so I wouldn’t think is going to bite the hand that feeds it, at least just yet. The danger is if countries with large US$ reserves, decide to dump the dollar for belligerent, or global political leverage.
