A big swath of the market isn't really paying that $125 a barrel number you hear about seemingly every hour. In China, India and the Middle East, governments are heavily subsidizing oil for their consumers and corporations, leading to rampant over-consumption - and driving up prices even more.
But sooner or later the world won't keep paying those prices: Eventually, the price must fall back to the cost of that last barrel to clear the market.
So what does that barrel cost today? According to Stephen Brown, an economist at the Dallas Federal Reserve, that final barrel costs just $50 to produce. And when the price is $125, the incentive to pour out more oil, like homebuilders' incentive to build more two years ago, is irresistible.
It takes a while to develop new supplies of oil, but the signs of a surge are already in place. Shale oil costing around $70 a barrel is now being produced in the Dakotas. Tar sands are attracting investment in Canada, also at around $70. New technology could soon minimize the pollution caused by producing oil from our super-plentiful supplies of coal.
"History suggests that when there's this much money to be made, new supplies do get developed," says Brown.
That's just the supply side of the equation. Demand should start to decline as well, albeit gradually.
"Historically, the oil market has under-anticipated the amount of conservation brought on by high prices," says Brown. Sales of big cars are collapsing; Americans are cutting down on driving. The airlines are scaling back flights.
We've learned another important lesson from the housing market: The longer prices stay stratospheric, the worse the eventual crash - simply because the higher the prices and bigger the profit margins, the bigger the incentive to over-produce.
It's even possible that, a few years hence, we could see a sustained period of plentiful oil supplies and low prices, meaning $50 or below.
A similar scenario occurred following the price explosion in the 1970s and early 1980s. The price spike caused the world to cut back sharply on oil consumption. By the mid-80s, oil prices had fallen from almost $40 to around $15. They remained extremely low for two decades.
It's impossible to predict how the adjustment this time will take shape, just as it was in housing. There the surge in supply came in places the experts swore there was "no supply," and wouldn't be any. Builders found a way to extend vast tracts of homes into California's Inland Empire and Central Valley, and even build "in-fill" projects near the densely-populated coasts.
An earlier bubble is also instructive. In the early 1980s silver prices jumped from $10 to $50 on the theory that the world was facing a permanent shortage of silver. Suddenly ads appeared asking homeowners to bring their tea sets and jewelry to Holiday Inns for a big price. Silver supplies poured from seemingly nowhere, out of America's cupboards, of all places.
And so it will be with oil. We don't know where the new abundance will come from, from shale, or tar sands or coal or an OPEC desperate to regain market share. We just know that it will appear. With prices like these, it always does.
