Oil Is the Cheap Date From Hell

Wherever oil goes, the stock market goes. This relationship has got to end.

It’s scary out there. The rout in the stock market that began around Jan. 1 took a turn for the worse early this month. By Feb. 10 the Standard & Poor’s 500-stock index was down 9 percent for the year. That’s its worst start since the recession year of 2008. Falling oil prices were blamed: A meeting between Saudis and Venezuelans aimed at curbing production had ended inconclusively. West Texas Intermediate fell again below $28 a barrel—more than 70 percent off its 2014 high. Trigger-happy investors have gotten accustomed to selling stocks whenever oil dips. With oil in serious oversupply, it’s hard to sustain any kind of recovery on Wall Street. “The toughest problem for people to deal with is oil getting linked with the market,” says Tobias Levkovich, Citigroup’s chief U.S. equity strategist.

Just in time for Valentine’s Day, it appears that oil and stocks have developed an unhealthy, codependent relationship. They’re way too deep into each other. Where one market goes, the other follows. If they were people, a counselor would be urging a trial separation. “This is highly unusual,” Torsten Slok, chief international economist at Deutsche Bank, wrote to clients in late January. “Call it the oil correlation conundrum.”
