The ongoing sell off in commodity and energy markets is starting to become an all out rout, which may turn into a full blown crash. The volatility has been stunning, and it looks like a lot of large funds are now being forced to liquidate positions across the board as the losses and margin calls pile up. Silver is down more than 8% today and crude oil has lost nearly 6%. Shares of Silver Wheaton (NYSE:

), a leading silver miner, have shed 8.61% to $33.63 on the session.
