As volatile crude oil prices show a weekly range in excess of $5 per barrel, what is the real effect of high prices?

HY Markets Analysts:

Fears of supply disruption continue to violently move oil prices on uncertainty. This year already, WTI crude oil prices have a range in excess of $12 per barrel; great for speculative investors who trade on volatility, but not so great for importers of the rich commodity.
Perhaps the most alarming fact is that the volatility experienced so far is on the threat of severe supply disruption; meaning that if the worst case scenario is realised and severe supply disruption does take place, then there is no telling how high crude oil prices could rise.
