It’s been a while since the world has been truly preoccupied with the threat of sustained high oil prices. The global economic recovery has been muted, and a double-dip recession remains possible.

But that dour prospect shouldn’t make executives sanguine about the risk of another oil shock. Emerging markets are still in the midst of a historic transition toward greater energy consumption. When global economic performance becomes more robust, oil demand is likely to grow faster than supply capacity can. As that happens, at some point before too long supply and demand could collide—gently or ferociously.

The case for the benign scenario rests on a steady evolution away from oil consumption in areas such as transportation, chemical production, power, and home heating. Moves by many major economies to impose tougher automotive fuel efficiency standards are a step in this direction. However, fully achieving the needed transition will take more stringent regulation, such as the abolition of fuel subsidies in oil-producing countries, Asia, and elsewhere, as well as widespread consumer behavior changes. And historically, governments, companies, and consumers have been disinclined to tackle tough policy choices or make big changes until their backs are against the wall.
