and has been substantially
underpriced for years.
While people want desperately for this to be a bubble, unfortunately this is only the beginning.
Check out Krugman's take:
The Oil Nonbubble“The Oil Bubble: Set to Burst?” That was the headline of an October 2004 article in National Review, which argued that oil prices, then $50 a barrel, would soon collapse.
Ten months later, oil was selling for $70 a barrel. “It’s a huge bubble,” declared Steve Forbes, the publisher, who warned that the coming crash in oil prices would make the popping of the technology bubble “look like a picnic.”
Even if this were purely a financial play on the part of the speculators, it would have major consequences in the material world. Faced with higher prices, drivers would cut back on their driving; homeowners would turn down their thermostats; owners of marginal oil wells would put them back into production.
As a result, the initial balance between supply and demand would be broken, replaced with a situation in which supply exceeded demand. This excess supply would, in turn, drive prices back down again — unless someone were willing to buy up the excess and take it off the market.
The only way speculation can have a persistent effect on oil prices, then, is if it leads to physical hoarding — an increase in private inventories of black gunk. This actually happened in the late 1970s, when the effects of disrupted Iranian supply were amplified by widespread panic stockpiling.
But it hasn’t happened this time: all through the period of the alleged bubble, inventories have remained at more or less normal levels. This tells us that the rise in oil prices isn’t the result of runaway speculation; it’s the result of fundamental factors, mainly the growing difficulty of finding oil and the rapid growth of emerging economies like China. The rise in oil prices these past few years had to happen to keep demand growth from exceeding supply growth.
