Low prices for many people will be crisis. If the price of gold goes to 900 dollars / ounce a lot of people will see it as a crisis because a lot of people believe that gold is holy and it can never go down. That would be a crisis in price.
Certainly if war breaks out in the world that will make gold go up, it will make crude oil go up. Everything will go up, oil, agriculture, gold. Yes, a crisis would be bullish for gold as low prices would be good for gold.
