Build in US oil inventories:
API crude oil inventories rose 2.3mln barrels so this isn't quite the 'surprise' it looks like.
- Gasoline inventories -1725K vs +300K exp
- Distillates +235K vs +1800K exp
- Cushing inventories +813K vs +300K exp
The oil numbers are bearish for crude but gasoline and distillates are bullish. But crude is under pressure after the data.
