The slump reflects a fundamental change in the outlook for the oil prices. A month ago, traders were concerned that a looming shortage of oil would push crude futures to $100 a barrel. Now, supply is expected to swamp demand at the start of 2019.
As a result, oil prices have plunged more than $20 a barrel since the start of October, when Brent crude rose to nearly $87 a barrel and U.S. crude traded just shy of $77. Both benchmarks are now trading firmly in bear market territory, having fallen more than 20 percent from their 52-week highs.
Stock market sell-off
That left oil prices vulnerable to a pullback just as the stock market was about to sell off. One week after crude futures struck their highs, two-thirds of the stocks in the S&P 500 plunged into correction territory.
That kicked off a broad market rout that saw investors shed risk assets, including crude futures. Oil and stocks do not always move in tandem, but the assets were closely correlated during last month's sell-off.
Right around the same time that investors started dumping stocks and commodities, concerns about faltering oil demand sharpened.
Weaker consumption outlook
In October, both OPEC and the International Energy Agency said oil consumption would grow less than previously forecast, pointing to signs of slowing global economic growth due to trade tensions, rising interest rates and weak emerging market currencies.
The U.S. dollar has risen nearly 3 percent against a basket of currencies over the last two months. That makes crude oil, which is sold in dollars, more expensive to holders of other currencies.
Rising output
Meanwhile, the world's top three oil producers are pumping at or near all-time highs and the 15-member OPEC cartel is in the middle of a coordinated production increase.
U.S. output has topped 11 million barrels per day in recent months, while Russia is pumping at post-Soviet era highs at roughly the same level. Saudi Arabia has trailed just behind at 10.6 million bpd in October.
The rising production and weakening demand outlook now has much of the market convinced that supply will outstrip the world's appetite for oil early next year.
Iran waivers
The Trump administration's decision to allow eight countries to continue importing Iranian crude for the next six months has also relieved upward pressure on oil prices.
With demand growth looking shaky and oil prices collapsing, OPEC and its allies are now considering a fresh round of output cuts.
Last month, a committee representing the group said the alliance may have to once again throttle back production to prevent oversupply. The group essentially reiterated that position at its latest meeting on Sunday. The following day, Saudi Arabia's energy minister said the group believes an output cut approaching 1 million bpd may be in order.
Still, oil prices continued to move lower on Tuesday, after President Donald Trump urged OPEC and Saudi Arabia to stay the course and as Russia's energy minister continues to express skepticism about the wisdom of supply cuts.
