Now, China needs to stimulate its economy. It’s facing a very delicate situation indeed: It needs the money internally to finance its continued growth. However, if it were to sell dollar-denominated treasuries, several bad things would happen. Its currency would skyrocket — meaning the loss of its competitive low-cost-producer edge. Or, U.S. interest rates would go up dramatically — not good for its biggest customer, and therefore not good for China.
This is why China is desperately trying to figure out how to withdraw its funds from the dollar without driving it down — not an easy feat.
And the U.S. government isn’t helping: It’s printing money and issuing Treasuries at a fast clip, and needs somebody to keep buying them. If China reduces or halts its buying, the United States may be looking at high interest rates, with or without inflation.
All in all, this spells trouble — a big, big Chinese bubble. Identifying such bubbles is a lot easier than timing their collapse. But as we’ve recently learned, you can defy the laws of financial gravity for only so long. Put simply, mean reversion is a bitch. And the longer excesses persist, the harder the financial gravity will bring China’s economy back to Earth.
