West TX Oil Below $59 Amid Glut Speculation

Oil pared its ninth weekly advance, the longest rally on record, amid speculation a rebound in prices to near $60 a barrel will sustain a market glut.

Futures slid as much as 0.5 percent in New York. Oil supply from OPEC and U.S. shale drillers is set to expand later this year, preventing further price increases, hedge fund manager Pierre Andurand said. Crude stockpiles in the U.S. are more than 100 million barrels above the five-year average for this time of the year and near the highest level since 1930, government data show.

Oil has rebounded from a six-year low in March amid signs U.S. output is slowing as drillers reduce the number of active rigs to the fewest since 2010. Oil prices are set to slide as their rally to the highest level this year threatens to prolong the global glut, according to Goldman Sachs Group Inc.
