People who cite margin req's in order to 'explain' commodity price movements are generally absolutely clueless.
Expect continued margin increases in this environment. Some believe margin requirements will be cash, before this is all over. Most of the talk about gold bubbles, is coming from the money management community anyway. They don't know where gold is headed anymore than you or I.
Interest rates are the biggest long-term driver of gold prices, just like any other floating currency.
