No, the dollar is not in the crapper.
It's relative. Foreign governments have slowed down the fall of the dollar by investing heavily in U.S. treasuries. That investment has been very strong, actually. Yes, the dollar has declined and it is relatively weak. But no, it is not in the crapper. Not even close.
The main reason the crapper is a long way off is that the dollar is the main global currency. It's the currency used to set prices for raw materials, such as oil, copper, etc. And it's the currency used to conduct a large percentage of global trade. For example, Japan exports more than half of its exports in U.S. dollars. Australia, more than two thirds. South Korea, 85 percent. Even countries such as France and Germany, which do almost everything in Euros, use the dollar for a third of their exports.
Dollars also represent about two-thirds of the official foreign exchange reserves of governments worldwide. This all reflects America's political stability, large economy, low inflation, strongest financial markets, etc. And as long as China and Japan each have $1 trillion in U.S. dollars for the foreign exchange reserves, they will continue to do everything they can to keep the dollar out of the crapper. The dollar is a long way off from being in the crapper.
