My forecast and others that oil prices would remain stubbornly high this year were clearly wrong. What happened? Is it that consumers stopped driving? Did speculators pull out of the market? Were our forecasting abilities just poor? Looking at it with the benefit of hindsight, it was a little of all of the above.
First, our ability to forecast a single market in a global economy is limited at best. Perhaps the best analysis of the history of economic forecasting in a global economic crisis was published by Harvard economist Greg Mankiw in today's New York Times. If you don't read another article on the credit crisis, read this one:

Second, demand destruction occurred. Demand by U.S. drivers year over year is down. Global economic growth began to temper even prior to the credit crisis, reducing overall demand.
Third, the credit crisis and fears of a global recession drove equity prices down sharply. Financial buyers were forced to liquidate commodity positions to meet margin calls in equities. In recent days, the equity prices have had a far greater impact on oil prices than the fundamentals of supply and demand.
Finally, fear. Just as at $147 per barrel last summer, the price of oil reflects as much of what we think supply and demand will look like as what it is today. In the current crisis, the price reflects more what buyers and sellers fear it will look like.
Just as we overshot a market equilibrium price on the way up, we will likely overshoot it on the way down. Most estimates show that the marginal cost of producing a barrel of oil is in the $70 range. In a free, rational market, price will fall to marginal cost plus some normal profit. Historically, the oil market has not been a free market but rather influenced, though not necessarily controlled, by a cartel, leading to excess profits. And, the supply/demand balance is still precarious. IEA estimates that the world will consume 86.5 million barrels per day in 2009 and will produce 85 million barrels a day. In rational markets, that is a recipe for increasing prices. In today's market, who knows.
