What are you saying, that China's competitive advantage over the U.S. isn't due to their cheap Yuan?
Of course my friend!
There isn't a single way to become competitive in the global markets nowadays, there are many, governments use rate change as a tool to this purpose.
A brief history of my country regarding this can put some light in this matter:
As posted by me before in this thread, we had a crisis in 1989 that led to hyperinflation. The only way to keep the money value was to exchange it for US dollars as fast as you can. This was done by the worker, middle and upper classes.
So after the crisis was history the minister of economy at the time had the idea to change our currency and put it par with the dollar, 1peso=1dollar and the dollar was legal tender here, why not? everyone was doing it to protect the value of the hard earned money, government just made a law what all of us were doing.
As you can imagine, a deficitary government at the time, barely had the reserves in the central bank to meet this now imposed 1=1 parity (we cannot print dollars as the US) so our economy was stable for about a year or two. But the government kept printing pesos (again, we cannot print dollars doh!) but the exchange rate remained the same. If you do the math, you quickly figure out that the money needs to be backed with something.
Enter the era of Carlos Menem, our president during the 90s. A carnival of foreign debt bonds was used to back the ever expanding amount of pesos being printed without reserves in the central bank, this was done, of course, to not have inflation.
Another consequence of this, but this time for the general population was that the peso was "strong" This meant that it was cheaper for us to visit Miami than our own country for example.
This was also the death sentence of the local industry, when the peso became "strong" many quickly realized that importing stuff was cheaper than manufacturing it here, so during most of the 90's our industry almost died in slow agony.
These bonds were used, by foreign companies, to buy the Govt owned water/telephones/petrol/energy companies at pitty prices, as these bonds sometimes held only 1/10 of its value...
Fast forward to 2001, our next crisis, I also posted links about this early in this thread.
The carnival of bonds was over, our foreign debt skyrocketed, lots of dead people in the streets, we had 5 presidents in a week, one of them proclaimed in congress: "we will not honor the foreing debt" and everyone applauded... morons :shakehead
After the turmoil settled, the dollar no longer was tied to the peso, people with dollars in their accounts had them converted to bonds, and the rate went from 1=1 to 1dollar=4pesos to settle around 1=3
But there was a benefit of this new exchange rate, our almost defunct industry, with years of not updating their machinery, was all of the sudden "competitive", not because all of us went to work 20 hours a day for low wages, but because our products were cheap again for the global markets...
Over the recent years this led to an increase in reserves in the central bank, we paid all our debt with the IMF (International Money Fund) and other debts are being paid, our national foreign debt is slowly decreasing, or at least not increasing at the pace it used to grow.
Having more reserves meant that the peso/dollar rate would decrease right? NO, the govt keept the 3ish=1 rate so the industry remains "competitive"
So, in this brief history of my country I guess you can learn some things:
1- exchange rates can be modified at will by the governments.
2- if you pay using bonds, iou's, etc at some point these must be paid in hard cash
3- if you print money without real reserves, sooner or later it will lose it buying power.
4- if you don't have hard cash, iou's/bond owners will buy your land, basic industries for cheap.
5- the industry benefits from devalued currency, it makes them more competitive.
Like Hitler's failure to conquer Russia failed in the same way that Napoleon attempt, history repeats itself, there is something to learn by the US from Argentina failures in the last 20 years.
