The world economy: Who’s afraid of cheap oil?

Low energy prices ought to be a shot in the arm for the economy. Think again

ALONG with bank runs and market crashes, oil shocks have rare power to set monsters loose. Starting with the Arab oil embargo of 1973, people have learnt that sudden surges in the price of oil cause economic havoc. Conversely, when the price slumps because of a glut, as in 1986, it has done the world a power of good. The rule of thumb is that a 10% fall in oil prices boosts growth by 0.1-0.5 percentage points.

In the past 18 months the price has fallen by 75%, from $110 a barrel to below $27. Yet this time the benefits are less certain. Although consumers have gained, producers are suffering grievously. The effects are spilling into financial markets, and could yet depress consumer confidence. Perhaps the benefits of such ultra-cheap oil still outweigh the costs, but markets have fallen so far so fast that even this is no longer clear.

The new economics of oil

The world is drowning in oil. Saudi Arabia is pumping at almost full tilt. It is widely thought that the Saudis want to drive out higher-cost producers from the industry, including some of the fracking firms that have boosted oil output in the United States from 5m barrels a day (b/d) in 2008 to over 9m b/d now. Saudi Arabia will also be prepared to suffer a lot of pain to thwart Iran, its bitter rival, which this week was poised to rejoin oil markets as nuclear sanctions were lifted, with potential output of 3m-4m b/d.

Despite the Saudis’ efforts, however, producers have proved resilient. Many frackers have eked out efficiencies. They hate the idea of plugging their wells only for the wildcatter on the next block to reap the reward when prices rebound. They will not pack up so long as prices cover day-to-day costs, in some cases as low as $15 a barrel. Meanwhile oil stocks in the mostly rich-country OECD in October stood at 267 days’ net imports, almost 50% higher than five years earlier. They will continue to grow, especially if demand slows by more than expected in China and the rest of Asia. Forecasting the oil price is a mug’s game (as the newspaper that once speculated about $5 oil, we speak from experience), but few expect it to start rising before 2017. Today’s price could mark the bottom of the barrel. Some are predicting a trough of as low as $10.

The lower the better, you might say. Look at how cheap oil has boosted importers, from Europe to South Asia. The euro area’s oil-import bill has fallen by 2% of GDP since mid-2014. India has become the world’s fastest-growing large economy.

Yet the latest lurch down is also a source of anxiety. Collapsing revenues could bring political instability to fragile parts of the world, such as Venezuela and the Gulf, and fuel rivalries in the Middle East. Cheap oil has a green lining, as it drags down the global price of natural gas, which crowds out coal, a dirtier fuel. But in the long run, cheap fossil fuels reduce the incentive to act on climate change. Most worrying of all is the corrosive new economics of oil.

In the past cheap oil has buoyed the world economy because consumers spend much more out of one extra dollar in their pocket than producers do. Today that reckoning is less straightforward than it was. American consumers may have been saving more than was expected. Oil producers are tightening their belts, having spent extravagantly when prices were high. After the latest drop in crude prices, Russia announced a 10% cut in public spending. Even Saudi Arabia is slashing its budget to deal with its deficit of 15% of GDP.

Cheap oil also hurts demand in more important ways. When crude was over $100 a barrel it made sense to spend on exploration in out-of-the-way provinces, such as the Arctic, west Africa and deep below the saline rock off the coast of Brazil. As prices have tumbled, so has investment. Projects worth $380 billion have been put on hold. In America spending on fixed assets in the oil industry has fallen by half from its peak. The poison has spread: the purchasing managers’ index for December, of 48.2, registered an accelerating contraction across the whole of American manufacturing. In Brazil the harm to Petrobras, the national oil company, from the oil price has been exacerbated by a corruption scandal that has paralysed the highest echelons of government.
