The price of oil dropped another 1 percent Tuesday to below $94 per barrel, extending a month-long slide on expectations of rising supplies.
Benchmark U.S. crude for December delivery fell $1.07, or 1.1 percent, to $93.55 per barrel in midday trading in New York. Brent crude, which is used to price international oil used by many U.S. refiners, fell 49 cents to $105.74.
U.S. crude stockpiles have increased in each of the past six weeks, mostly because of rising domestic production, and were more than 10 percent above their five-year average near the end of October.
Figures for the week ending Nov. 1 are expected to show a further increase of 2.5 million barrels, according to a survey of analysts by Platts, the energy information arm of McGraw-Hill Cos.
The weekly supply report from the Energy Department's Energy Information Administration will be out on Wednesday.
Oil climbed above $110 in early September amid instability in Egypt and the civil war in Syria. It began to sink later September as Iran re-entered international talks over its nuclear program and rising U.S. crude stockpiles indicated muted demand. Oil's decline steepened in October — crude is down 10 percent since closing at $104.10 on October 2.
Continued instability in Egypt and new fighting in Libya that is impacting Libyan crude exports are elements likely stemming oil's slide at least somewhat. "The ongoing delivery outages in Libya are preventing prices from falling," said analysts at Commerzbank in Frankfurt.
