Oil prices plummeted below $40 a barrel amid an increasing oversupply, further pressuring the industry.

Crude oil futures settled at $39.94 in New York, down 4.6%. Brent closed at $42.49 on ICE Futures Europe, down 4.4%. Oil prices last ended below $40 in the United States last August, when woes regarding the global economy affected financial markets.

OPEC producers and the US are embroiled in a battle for market share, which has left the world flooded with oil. For the last several months, Saudi Arabia has led a policy of escalating oil output to pressure weaker American counterparts in the US and other nations.

Meanwhile, the Organization of the Petroleum Exporting Countries is scheduled to meet this week.
