Why Oil Is Continue to Fall Down

Why the oil price is falling (www.economist.com)

THE oil price has fallen by more than 40% since June, when it was $115 a barrel. It is now below $70. This comes after nearly five years of stability. At a meeting in Vienna on November 27th the Organization of Petroleum Exporting Countries, which controls nearly 40% of the world market, failed to reach agreement on production curbs, sending the price tumbling. Also hard hit are oil-exporting countries such as Russia (where the rouble has hit record lows), Nigeria, Iran and Venezuela. Why is the price of oil falling?

The oil price is partly determined by actual supply and demand, and partly by expectation. Demand for energy is closely related to economic activity. It also spikes in the winter in the northern hemisphere, and during summers in countries which use air conditioning. Supply can be affected by weather (which prevents tankers loading) and by geopolitical upsets. If producers think the price is staying high, they invest, which after a lag boosts supply. Similarly, low prices lead to an investment drought. OPEC’s decisions shape expectations: if it curbs supply sharply, it can send prices spiking. Saudi Arabia produces nearly 10m barrels a day—a third of the OPEC total.

Four things are now affecting the picture. Demand is low because of weak economic activity, increased efficiency, and a growing switch away from oil to other fuels. Second, turmoil in Iraq and Libya—two big oil producers with nearly 4m barrels a day combined—has not affected their output. The market is more sanguine about geopolitical risk. Thirdly, America has become the world’s largest oil producer. Though it does not export crude oil, it now imports much less, creating a lot of spare supply. Finally, the Saudis and their Gulf allies have decided not to sacrifice their own market share to restore the price. They could curb production sharply, but the main benefits would go to countries they detest such as Iran and Russia. Saudi...
