Is it better or worse for the US economy if the dollar falls?
Won't goods overseas sell better if the dollar is lower? What's the downside of the dollar falling? It's been 104 to the yen before, back in '94 I think.
With a bum dollar, our exports sell easier. Our imports cost more. So if you produce stuff, it's good. If you consume stuff, it's bad. (generally speaking, it's much more complex than that)
The bad thing is this:
If we are running a deficit and need to borrow money, other countries can snatch it up for less. Good right? Bad. When the dollar increases, we have to pay them back.
Say 1 ruble buys $0.50 USD of stuff:
The US borrows 2 rubles to buy $1 of stuff today.
Tomorrow, the dollar is strong. 1 ruble buys $1 USD of stuff.
The US still has to pay back 2 rubles. Instead of having $2 worth of stuff, we only got $1.
The commies just ripped us of. That's how the game is played. Unless others consider you a "bad risk" (Like S. Korea & Taiwan yesterday). Then you can't get a loan... things get REAL ugly when that happens. Remember Mexico?
Another country will only be affected by a falling dollar if it holds a bunch of US currency. That's why S. Korea and Taiwan are "diversifying" by selling their US currency for the Euro. They have more faith in that economy over ours. The World Bank is following their lead. It's kind of like stocks in a way. The US gvmnt can hold the "value" of the dollar up only if it buys it's money back. Otherwise, the other countries have to find someone to buy it (just like a stock). If nobody wants it, it can plummet. That's what happened years ago with the peso.
