The plunge in oil and gas stocks could nudge the industry toward a restructuring, as crude oil prices collapse and the rapid spread of the COVID-19 illness threatens global economic growth.

The S&P Oil and Gas index closed down almost 34% and was more than 70% below its level of a year ago. For the year, the index has fallen 64%. On March 9, the Dow Jones industrial average was off 7.8%.

The U.S. benchmark WTI price, which closed at $41.28 per barrel (bbl) on March 6, dropped almost 26% to $30.44/bbl. Global benchmark Brent was off about 26% at $33.70/bbl.

The price collapse, combined with slowing demand growth from an increasingly shaky world economy, could result in a harsh setback for an oil and gas industry burdened by heavy debt.

“The price collapse could be the trigger for a new phase of deep industry restructuringone that rivals the changes seen in the late-1990s,” said Tom Ellacott, Wood Mackenzie’s senior vice president for corporate upstream, in a released statement.

“This is not the first time we’ve seen a price warthe last was as recently as 2015-2016,” he said. “But this time, oil demand is also weak as the coronavirus outbreak depresses global economic growth. The macro-economic backdrop is completely uncharted waters for oil and gas companies.”

WoodMac has calculated a Brent price of $53/bbl as a breakeven point. If the price were to average $35/bbl for the remainder of the year, the cost to the global industry would be around $380 billion.

Since the most recent downcycle, energy companies have focused on capital discipline, meaning that this time there is not much excess spending to cut.

“More highly leveraged players will be forced to make the deepest cuts to stave off bankruptcy,” Ellacott said. “Aggregate cash burn from the companies we cover in our corporate benchmarking tool amounts to US$130 billion in 2020 in the US$35/bbl Brent scenario.”

Raising capital is also more difficult now, especially for independents, and many companies have already made their obvious asset sales, he said.
