API’s gasoline inventories 
On December 19, 2017, the API released its crude oil inventory report. It reported that US gasoline inventories rose by 2 MMbbls (million barrels) on December 8–15, 2017. Analysts expected that US gasoline inventories could have risen by 2.2 MMbbls during the same period. Any rise in gasoline inventories is bearish for gasoline and oil (USL) prices.
The massive rise in gasoline inventories pressured oil prices in the last few weeks. Lower oil (DWT) prices have a negative impact on energy producers’ (VDE) (PXI) earnings like BP (BP), W&T Offshore (WTI), Northern Oil and Gas (NOG), and Sanchez Energy (SN).
API’s distillate inventories
The API added that US distillate inventories fell by 2.85 MMbbls on December 8–15, 2017. The market expected that US distillate inventories could have fallen by 1.3 MMbbls during the same period. Any fall in distillate inventories is bullish for diesel and oil (USO) prices.
