"Volatile oil price good or bad?"

Chaos Theory says that there is a region of instability between one stable state and another.
The climate will become volitile due to CO2.
When a stock market collapses there is a period of instability.
I see Volatility as a symptom of change to another state.

I disagree. I see volatility as an advantage to short-term traders and speculators, therefore it will be induced by every means possibly by them. I'd guess we're only seing the beginning of their experiments with methods to induce it everywhere we turn. Long-term price stability is unprofitable for those who gain by making bets.
