high gas prices

With oil prices soaring ever higher, Saudi Arabia stepped in last week and vowed to increase its production by 25% if necessary.

But while that assurance managed to siphon a few dollars off of oil futures, the reality is there's nothing Saudi Arabia - or anyone else, for that matter - can do about rising oil prices.

In fact, crude is still on track to reach $150 a barrel by mid-summer.

As Saudi Oil Minister Ali Naimi pointed out last week, current oil supplies already exceed global demand by 1 million-2 million barrels per day.

For its part, Saudi Arabia is already breaking its own OPEC-imposed production quota limit, churning out about 10 million barrels of oil per day - close to its 12.5 million barrel capacity.

Yet the effect of that production has been negligible.

Oil is still trading at $106 a barrel on the NYMEX - something that has clearly flummoxed the world's largest oil producer.

"I think high prices are unjustified today on a supply-demand basis," said Naimi. "We really don't understand why the prices are behaving the way they are."

Naimi and his colleagues may not understand oil's price gyrations, but Dr. Kent Moors, an adviser to six of the world's top 10 oil companies and energy consultant to governments around the world, does.

"Despite the excess storage capacity in both the U.S. and European markets and the contracts already at sea, oil traders set prices on a futures curve," said Moors. "In a normal market the price is set at the expected cost of the next available barrel. During times of crisis, on the other hand, that price is determined by the cost of the most expensive next available barrel."

And with tensions with Iran running high, we are currently in crisis mode. Pushed to the brink by Western sanctions, Iran has threatened to close the Strait of Hormuz - the narrow channel in the Persian Gulf through which 35% of the world's seaborne oil shipments and at least 18% of daily global crude shipments pass.

If Iran closes the Strait of Hormuz, crude oil prices will pop by between $30 and $40 a barrel within hours. Should the strait remain closed for 72 hours, oil trading will push up the barrel price to $180 in New York, and closer to $200 in Europe.

The situation is further complicated by potential military conflict - such as an Israeli air strike on Iran's nuclear facilities.

And with indications that Iran will have the ability to develop nuclear weapons in the next 18 to 24 months, Western powers have apparently shifted their focus from halting Iran's nuclear program to sowing instability in the country with the hopes of catalyzing a regime change.

So what does that mean for investors?
