The S&P 500 and Dow Jones Industrial Average were sharply lower on Wednesday, June 21, as crude oil stretched a selloff into day two.

The S&P 500 was down 0.22%, and the Dow fell 0.3%. The Nasdaq added 0.52%. 

Crude oil prices retreated further into a bear market, after having fallen more than 20% from a late February high. Crude plunged more than 2% on Tuesday, June 20, on worries over global oversupply and ballooning production.

Crude stockpiles dropped by 2.5 million barrels over the past week, according to the Energy Information Administration. Analysts anticipated a decline of 2.1 million barrels. Gasoline supplies fell, while distillates climbed. 

West Texas Intermediate crude was down 2.9% to $42.23 a barrel on Wednesday.

"Bottom line is that there is too much oil on the market, which could be a function of slowing business conditions in emerging markets and, to a lesser extent, the U.S.," said Brian Sozzi over on our premium site for investors, Real Money. Get his insights with a free trial subscription.

The Federal Reserve could begin to unwind its $4.5 trillion balance sheet as soon as September, Philadelphia Fed President Patrick Harker said on Wednesday, the latest in a string of hawkish Fed commentary. Harker said in comments with The Financial Times that he backed a "pause" in hiking rates while the Fed addresses its balance sheet.

It has been a busy week of Fed speeches in the days following the central bank's decision to raise interest rates for the second time in a year. The Fed hiked rates by 25 basis points at its meeting on Wednesday, June 14, a decision widely anticipated. The central bank views softening inflation trends as merely transitory and anticipates another interest rate hike before the year is out.
