Crude-oil futures plummeted further below the key $40 support level on Wednesday as surging coronavirus cases and rising stockpiles drove fresh concern about prolonged market weakness.

Contracts for West Texas Intermediate crude sank as much as 6.4%, to $37.04 per barrel, the lowest level since early October. Brent crude, oil's international standard, tumbled 5.8%, to $38.83 per barrel, at intraday lows.

Resurgences in coronavirus cases have intensified concerns about whether oil demand can return to pre-pandemic levels. Prices first plummeted in March as initial outbreaks curbed travel activity and prompted widespread lockdowns.

Another wave of cases risks a similar decline in demand as oil hovers at about $40 per barrel. Europe is already taking action to curb the virus' spread, with Germany and France reportedly set to impose new lockdown measures.

A Wednesday-morning report from the Energy Information Administration added to oil's slump. It said US crude-oil inventories climbed by 4.3 million barrels last week, the biggest stockpile increase since late July. Total inventories stood at 492.4 million barrels, roughly 9% higher than the five-year average for this time of year.

The oil sell-off joined other sliding markets in choppy Wednesday trading. The S&P 500 tumbled by the most in nearly two months on new coronavirus concerns. And Cboe's VIX, Wall Street's preferred gauge of market volatility, surged to its highest level since mid-June.

WTI futures traded at $37.11 per barrel as of 11:30 a.m. ET, down roughly 40% year-to-date.

Brent crude traded at $39.03 per barrel, down 41% year-to-date.
