The US dollar has a definite value and while the devaluation of the dollar is constant, so is the devaluation of all other currencies, and since many financial transactions in the US require investors to buy US dollars, it doesn't really matter what the absolute value of the US dollar is and all that matters is its value relative to the value of all of the other devalued currencies.I've been telling everyone I know for years, all this fake fiat is worthless. If you can just print more with impunity indefinitely it's of no value. Turn it in to hard assets b/c it's all going away. All the macro economic evidence is there if you care to look. It's all unsustainable. This bank is just the first of many... mark my words.
When interest rates rise in the US and foreign investors want in on that sweet US yield or they want to buy US treasuries, they have to sell their local currency and buy US dollars. Since the Federal funds rate basically sets the interest rates for the world and since inflation is basically highein nearly every other major market compared to the US, the US dollar is and will for the foreseeable future remain the currency of choice and thus not "worthless".
Inflation in other countries:
United Kingdom = 10.1%
Australia = 7.8%
Japan = 4.3%
Germany = 8.7%
France = 6.2%
India = 6.2%
China is a special case and has low inflation due to their tight CV-19 restrictions but their economy is struggling with a GDP of only 3% and a target of 5%. They are currently where we and the rest of the world were just after the CV-19 shutdown in mid to late 2020 when demand dropped off a cliff.
The US dollar is far from worthless and the world is stil very much dependent on it.
