Crude oil for August delivery fell yesterday (Thursday) below the $80 line to $78.20 a barrel on the New York Mercantile Exchange.
Oil prices breaking the $80 line can have a psychological impact on traders, which could send oil spiraling even further.
"Oil is participating in the broad decline of equities and commodities," Rich Ilczyszyn, chief market strategist and founder of Iitrader.com in Chicago, told Bloomberg News. "We broke an extremely key level for oil, the previous monthly low around $81."
Oil prices fell more than 3.5% the day after the Fed announced a disappointing extension of Operation Twist.
The commodities market, measured by the S&P GSCI Spot Index, entered into a bear market yesterday, off 22% from its highest close of the year on Feb. 24.
Many experts think oil is reaching a bottom - but there are other factors still in play.
