Stock tumbled on Monday, as a dramatic cratering in crude prices stoked concerns over weak demand in an oversupplied market that’s been battered by the worldwide coronavirus outbreak.

The May contract for U.S. West Texas intermediate crude oil (CL=F), which expires on Tuesday, erased its entire value — plunging below zero for the first time in history before settling at -$37.63 per barrel. The June contract for the commodity (CLM20.NYM) also sank sharply, but held above $20 per barrel Monday afternoon.

Prices for Brent crude oil, the international standard, also fell Monday morning, albeit by a less extreme margin than prices for U.S. oil. Brent was down 5.27% to $26.60 per barrel.

The steep move pushed blue-chip and tech shares sharply lower. It also underscored how weak demand means oil storages are filled to the brim with crude, which is unlikely to be used in a global economy frozen in place by the COVID-19 crisis.

“With a huge surplus in crude products filling inventories on land, there is a clear benefit to those producers whom are able to put their oil out to sea,” Joshua Mahony, senior market analyst at IG, wrote in an email.

“Unfortunately, the lack of demand and landlocked nature of production in the U.S. and Canada has already started to provide negative prices across a number of crude products in North America.”

The declines extended a months-long drop for the commodity prices, which have been anchored both by fears of a supply glut and demand destruction from the outbreak.

On Monday, coronavirus cases topped 2.4 million globally, and the death toll rose above 166,000, according to Johns Hopkins data. U.S. confirmed cases totaled more than 761,000, but tentative signs suggest the new cases are leveling off, especially in hard-hit New York.

Last week, the Trump administration outlined a three-phase plan for states to each gradually bring businesses and other daily operations halted during the pandemic back online. Still, individual state officials have been hesitant about announcing a near-term easing of social distancing standards in absence of widespread testing or viable treatment or vaccine. Northeast states led by New York last week extended social distancing measures to at least May 15.

Distancing measures have helped keep new coronavirus cases in check but also contributed to broad economic stress in the U.S., triggering a staggering 22 million individuals to file for unemployment insurance over the past four weeks alone. Even when distancing begins to let up, many economists warn recovering these losses will take time.

“A double-digit rebound in GDP growth in the third quarter still seems like a decent bet, but it won't recover all the lost ground,” Ian Shepherdson, chief economist for Pantheon Macroeconomics, wrote in a note Sunday. Shepherdson’s anticipation is for a 30% annualized drop in GDP in the second quarter, a margin about in-line with many other economists’ grim outlooks for the quarter.

“That can't happen if, for example, restaurants have half the seating density than in the pre-virus era, cinemas can sell only one third of their seats, and airlines have to leave the middle seat empty,” he added. “No matter how much fiscal stimulus Congress pumps in—and more is coming—earnings across wide swathes of the economy will be crushed for an extended period.”

U.S. policymakers have been working on providing further relief to the small businesses hit hardest by the coronavirus. The PPP first passed in Congress’s $2.2 trillion stimulus package late last month ran out of funds in less than two weeks.

10:58 a.m. ET: Crude oil futures slide further, hitting the lowest level since 1986

May futures for West Texas intermediate crude oil dropped 40.78% to $10.82 per barrel as of 10:58 a.m. ET, tumbling to the lowest level in more than three decades. If prices fall below $9.75 per barrel, they will have reached their lowest level on record, based on crude oil futures data spanning back to 1983.

Brent crude oil prices fell 5.13% to $26.64 per barrel.

Speaking to Yahoo Finance on Monday, veteran oil trader John Caruso said he believes crude is bottoming out, and that there’s a “100% premium” priced into the June contract. However, he added that with U.S. crude this cheap, it’s going to be “very difficult” for a lot of domestic drillers to survive the current rout.

7:49 a.m. ET: Halliburton slashes capital spending, projects declines in North America business

Halliburton (HAL) on Monday joined peer oilfield operators in slashing capital spending plans for the year to rein in costs as oil prices slump. The company expects capital spending to be down 56% to $800 million in 2020.

For the fiscal first quarter, Halliburton delivered adjusted earnings per share from continuing operations of 31 cents on revenue of $5.04 billion, with the latter down 12% over last year. The adjusted EPS figure excludes $1.1 billion in impairment and other charges during the quarter. Net losses were $1.2 billion, versus net income of $152 million in the same quarter last year.

Halliburton said it “cannot reasonably estimate the period of time that the COVID-19 pandemic and related market conditions will persist, the extent of the impact they will have on the Company’s business, liquidity, consolidated results of operations and consolidated financial condition, or the pace of any subsequent recovery,” according to a statement. “For the remainder of 2020, the Company expects a further decline in revenue and profitability, particularly in North America.”

Shares of Halliburton fell 7.7% to $7.00 per share as of 7:49 a.m. ET Monday. The stock was down 69% for the year to date through Friday’s close.
