Some analysts cite a lack of preparation for a looming economic event.
Last week the price of crude oil broke new records, running about $110 a barrel. That's well above the previous record (in inflation-adjusted dollars) reached in 1980 after the revolution in Iran resulted in the nationalization of its oil.
Since tanks of crude are full to brimming, many traders in oil markets suspect that $110 could be the top price for now. But a growing number of oil-market analysts reckon the supply of oil to the world economy has reached a peak or is about to. The discoveries of new oil are now exceeded by the output of old oil. At some point, global oil output will start to decline, as happened in the United States in 1971.
If that is the case, before long $100-a-barrel oil will be regarded as "the good old days," says Robert Hirsch, a senior energy analyst at Management Information Services, Inc., a Washington, D.C., research and consulting firm.
The price of oil in the New York futures market, a financial market that promises the delivery of oil in the future, has already climbed more than $20 in the past two months.
Global oil production has been on a plateau at around 85 million barrels per day (b.p.d.) for about 3-1/2 years. It is widely debated whether that output level could be pushed much higher to reach demand in the future, which, according to the International Energy Agency (IEA) in Paris, could reach 98.5 million b.p.d. in 2015 and 116.3 million b.p.d. in 2030.
