Now if you want to have a sleepless night, or you want to reassure yourself that buying some shares of Barrick Gold (NYSE:ABX), Goldcorp (NYSE:GG), Kinross Gold (NYSE:KGC), Silver Wheaton (NYSE:SLW) and Silver Standard Resources (Nasdaq:SSRI) are a good idea, check out what Stephen Leeb of The Complete Investor wrote to us today:

"Will Israel attack Iran? Or is the U.S. secretly planning to make peace with this rogue nation? Either way, what will these events do to oil prices? That's the trillion-dollar question these days. But buried in a recent New York Times article on the subject is the deeper truth that shows that – no matter what action Israel, the U.S., or Iran takes – or even if diplomacy triumphs – oil prices will skyrocket regardless.

"The head of OPEC, Abdalla Salem el-Badri, said it all last week. On the one hand, he admitted that OPEC could not make up for the loss of Iranian oil, in the event it goes offline. On the other hand, he said that OPEC might halt investment in new oil production capacity.

"If oil supplies are so tight already that OPEC cannot do without Iran (which contributes less than 5% of the world's oil), how will the world meet fast rising demand from the developing world over the next few years? And with supplies so tight, why cut back on development ... unless you already know you've reached a permanent peak and can't raise output no matter how hard you try?

"Let's face it. Whether another war breaks out in the Middle East or not, oil prices will shoot to the moon over the next few years, rewriting the rules on which investments will pay off and which will collapse into dust. Inflation will soar, along with the cost of producing all commodities, destroying the real return on most securities."

When I read Leeb's book "The Coming Economic Collapse...How You Can Thrive When Oil Costs $200 a Barrel," it was 2006 and oil was around $70 a barrel, so this gentleman and his team certainly seem to be on the ball (or on "the barrel" depending on your perspective).

That is why I think a subscription to The Complete Investor (www.CompleteInvestor) is something you should seriously consider. I'm a subscriber, and I'm NOT PAID to recommend this uniquely valuable newsletter or any newsletter.

Tbey propose that:

- "Russian and Saudi Arabian oil production have peaked – leaving the world with no way to meet our rapidly growing demand for energy.

- Oil prices must surpass $240 a barrel in the next few years in order to avoid severe shortages...
