OPEC drives up oil prices in a new way

You already know part of the reason for that. The developed economies of the world have become a lot less energy intensive over the past three decades. For example, in the United States, energy use per unit of economic production (gross domestic product) fell by 28% from the OPEC oil embargo of 1973 through 1995.

Higher oil prices were responsible for much of that decrease in energy use. From 1995 through 2004, energy use per unit of the economy fell an additional 26%. This time the decline had less to do with energy prices, which plunged at the beginning of that period, than with the steady shift of the U.S. economy from manufacturing to service industries. The same trend shows up in Europe and Japan.

Because these economies use so much less energy per unit of GDP than they did 30 years ago, they're a lot less sensitive to increases in energy prices. Energy is simply a smaller part of the cost of doing business in these economies for most companies.

Rising economies relatively immune

The other part of the story that you probably know involves the developing economies of China, India and the rest of the rapidly industrializing world. Between 2000 and 2006, when global oil demand grew by 8 million barrels a day, growth from China alone accounted for about 32% of the total increase, according to the International Energy Agency. (The United States accounted for 12.5% of growth.)

Energy use in these developing economies has also been relatively insensitive to rising oil prices. Some developing economies -- China is the most important example -- are mixes of command-style and free-market economies where the government sets prices and determines profit goals.

Also, these economies are showing their own improvements in energy efficiency, and, most important, when an economy is growing at 11% a year, breakneck revenue growth overwhelms concerns that higher energy costs might cut into profit margins. Total profit is growing so fast that nobody worries much if margins are falling.

Subsidies encourage higher consumption

But there's a third part of the global energy demand story that hasn't received much attention until lately -- and it explains why higher oil prices haven't slowed global economic growth more rapidly and why OPEC is getting badly beaten by the energy traders these days.

Remember that I said that China had accounted for 32% of global growth in oil demand from 2000 to 2006 and that the U.S. had accounted for 12.5%? Well, there's another group of countries that, when it comes to global growth in oil demand, has been more important than the U.S. and only slightly less important than China. From 2000 through 2006, OPEC countries themselves accounted for 22% of global growth in oil demand.

In these OPEC countries, because oil consumption is so heavily subsidized, either directly in the consumer market or through government subsidies to energy-intensive industries, the rising market price of oil isn't felt much at all. Though higher market prices for oil are putting pressure on government budgets in these countries -- those subsidies cost money -- they have almost no effect on energy consumption.

From 2000 through 2006, oil consumption by OPEC countries climbed by 1.8 million barrels a day, or 29%. Consumption is projected to climb 400,000 more barrels a day this year. OPEC consumption has been growing at 2.5 times the rate of global consumption.

By the end of this year, consumption growth in OPEC countries will just about wipe out all the 2.2 billion barrels a day in increased production that OPEC has added since 2000.

Little reason for trend to change

Traders are right to assume that this trend isn't about to reverse anytime soon. Saudi Arabia and Iran are determined to use their oil riches to build energy-intensive economies. Venezuela, Mexico and Iran use higher oil revenue to fund their governments and to subsidize prices for everything from gasoline to pharmaceuticals to food. Young and increasingly well-off populations in these countries want the energy-consuming trappings of wealth that are already enjoyed in the developed countries.

And because subsidized domestic market prices for oil and gasoline are so low in OPEC countries, there's little incentive for improving energy efficiency or switching to other fuels.

As oil prices go up, the economies of the OPEC countries boom. That increases consumption in OPEC countries, which drives up oil prices and stretches out the economic boom. Which drives up consumption. Which sends oil prices up again.

I don't know whether you want to call this a vicious or a virtuous cycle, but a cycle it is, and it is clearly pointing to higher oil prices unless the Saudis can pull a couple of million barrels of production a day out of their hats.

The oil speculators have made a pretty good bet.
