I am hearing early reports from Kings World News that China plans on backing their currency, the Yuan, with gold. If that is the case and it is not 100% confirmed yet then that will spell trouble for the dollar. More countries will flock towards using the Yuan as a reserve currency as opposed to the dollar. This is absolutely a development to watch closely.
You could also see a massive short squeeze on gold. A short squeeze is when everyone rushes to take physical possession of gold but it is not all available so the price could jump up dramatically in a short squeeze situation.
China's strategy is to buy as much gold as they can as seceretly as they can without disturbing the price of gold. But insiders know what is going on. China is hoarding gold because they know gold, unlike the Euro, the US Dollar, and other fiat currencies, is real money.
