What oil at $100 a barrel would mean for the world economy

Surging crude prices are posing another headwind for the world economy after President Donald Trump’s zero pledge on Iran oil sales.

Brent crude has risen about 33 per cent this year and is close to the highest in six months. While higher prices due to strong demand typically reflects a robust world economy, a shock from constrained supply is a negative.

Much will depend on how sustained the spike proves to be. Exporting nations will enjoy a boost to corporate and government revenues, while consuming nations will bear the cost at the pump, potentially fanning inflation and hurting demand. Ultimately, there comes a point where higher prices may be damaging to everyone.

The impact will vary. Rising oil prices will hurt household income and spending and it could accelerate inflation. As the world’s biggest importer of oil, China is vulnerable, and many countries in Europe also rely on imported energy. Seasonal effects will also impact. With the Northern Hemisphere summer approaching, consumers can switch energy sources and scale back usage. A slowing world economy will also hurt demand and by extension keep a lid on prices.

For a sustained hit to growth, economists say oil would need to hold above $100. It also depends on dollar strength or weakness, given crude is priced in greenbacks. Analysis by Oxford Economics found that Brent at $100 per barrel by the end of 2019 means the level of global gross domestic product would be 0.6 per cent lower than currently projected by end-2020, with inflation on average 0.7 percentage points higher.

An upending of global oil trade around the Iran-Trump spat could continue to have a sizeable impact on financial markets, as the affected supply is as much as 800,000 barrels a day. Uncertainties around availability have already whipsawed oil markets. And the political sensitivities of these developments have other markets bracing for volatility.

Trump has pledged to help, alongside Saudi Arabia and the UAE., those needing to shift orders from Iran to another supplier. But US claims that its domestic supply can help offset the loss are a high bar to meet, given that the daily American output for similar crude is about a quarter of Iran’s.

Emerging economies dominate the list of oil-producing nations which is why they’re affected more than developed ones. The increase in revenues will help to repair budgets and current account deficits, allowing governments to increase spending that will spur investment. Winners include Saudi Arabia, Russia, Norway, Nigeria and Ecuador according to analysis by Nomura.

Those emerging economies nursing current account and fiscal deficits run the risk of large capital outflows and weaker currencies, which, in turn, would spark inflation. That, in turn, will force governments and central banks to weigh up their options: hike interest rates even as growth slows or ride it out and risk capital flight. Nomura’s losers list includes Turkey, Ukraine and India.

While US oil producers try to take advantage of any sales boost from customers moving away from Iran, the broader US economy won’t necessarily see benefits with oil price tags as high as $100 a barrel. It would be a squeeze on American consumers that are the backbone of still-steady economic growth. Prices at the gas pump already have risen more than 7 per cent this month to $2.89 a gallon, which could weigh on retail sales that jumped in March by the most since 2017.
