Kill Switch Installed on the Dollar: Made in China

What happens when Americans are no longer able to take money out of their stucco box ATMs to buy Chinese goods?

The Chinese don't want to get stuck holding all of that funny money!

But don't take my word for it:

Zhong Wei, deputy editor-in-chief of China Foreign Exchange Magazine, said China needed to make "innovative adjustments" to the management of its reserves, which swelled to US$987.9bil at the end of September.

The stash, the world's largest, was on track to hit the US$1.5tril mark in the second quarter of 2008, Zhong wrote in the overseas edition of the People's Daily, the ruling Communist Party's mouthpiece.

He estimated that China in fact needed reserves of no more than US$800bil.

"The current foreign exchange management regime is extremely unsophisticated and is obviously not suitable for China's almost US$1tril in reserves," he wrote.
Hmmm. If China only needs to hold a maximum of US$800 billion, who's going to buy the other US$700 billion that China plans on dumping?

Work that out while I go dig up some more garden beds.
