http://www.nytimes.com/2004/05/14/opinion/14KRUG.html?hp=&pagewanted=print&position=So far, the current world oil crunch doesn't look at all like the crises of 1973 or 1979. That's why it's so scary.
The oil crises of the 1970's began with big supply disruptions: the Arab oil embargo after the 1973 Israeli-Arab war and the 1979 Iranian revolution. This time, despite the chaos in Iraq, nothing comparable has happened — yet. Nonetheless, because of rising demand that is led by soaring Chinese consumption, the world oil market is already stretched tight as a drum, and crude oil prices are $12 a barrel higher than they were a year ago. What if something really does go wrong?
Let me put it a bit differently: the last time oil prices were this high, on the eve of the 1991 gulf war, there was a lot of spare capacity in the world, so there was room to cope with a major supply disruption if it happened. This time there isn't.
The International Energy Agency estimates the world's spare oil production capacity at about 2.5 million barrels per day, almost all of it in the Persian Gulf region. It also predicts that global oil demand in 2004 will be, on average, 2 million barrels per day higher than in 2003. Now imagine what will happen if there are more successful insurgent attacks on Iraqi pipelines, or, perish the thought, instability in Saudi Arabia. In fact, even without a supply disruption, it's hard to see where the oil will come from to meet the growing demand.
