Uncle Sam, your banker will see you now

Early this morning China let the idiots in Washington, and on Wall Street, know that it has them by the short hairs. Two senior spokesmen for the Chinese government observed that China’s considerable holdings of US dollars and Treasury bonds "contributes a great deal to maintaining the position of the dollar as a reserve currency."

Should the US proceed with sanctions intended to cause the Chinese currency to appreciate, "the Chinese central bank will be forced to sell dollars, which might lead to a mass depreciation of the dollar."
If Western financial markets are sufficiently intelligent to comprehend the message, US interest rates will rise regardless of any further action by China. At this point, China does not need to sell a single bond. In an instant, China has made it clear that US interest rates depend on China, not on the Federal Reserve. Paul Craig Roberts
