Brent crude dropped from a five-week high as Libya’s National Oil Corp. prepared to resume exports from its Hariga terminal. West Texas Intermediate slipped below $104 on U.S. inventory forecasts.

Brent’s premium to WTI shrank. A tanker will arrive at the port in eastern Libya today to load 1 million barrels of crude, according to Libya’s Arabian Gulf Oil. U.S. supplies probably grew from a four-month high, a Bloomberg survey showed before an Energy Information Administration report tomorrow. WTI reduced losses as U.S. stocks advanced.

“It looks like Libya is getting some oil out and it’s putting some downward pressure on oil,” said John Kilduff, a partner at Again Capital LLC, a New York-based hedge fund that focuses on energy. “We are going to see another build in inventories. The elements are in place for the price to go much lower.”
