U.S. crude oil inventories increased by 2.1 million barrels during the week ending July 16, the U.S. Energy Information Administration (EIA) said in a report on Wednesday.

The EIA report also showed crude stocks at Cushing, Oklahoma, a key U.S. oil hub, dropped by 1.4 million barrels in the latest week.
Meanwhile, total motor gasoline inventories fell 0.1 million barrels last week and distillate fuel inventories decreased by 1.3 percent, according to the EIA.
