Brent oil was whacked 5% lower last night to $56.07 as I write. The main cause was a giant surge in DOE reported US inventories, from Reuters:
U.S. crude oil inventories surged 10.95 million barrels – three times more than expected – to a modern-day record 482.39 million last week, U.S. government data showed, the biggest one-week increase since 2001. Stockpiles in Cushing, Oklahoma, rose by 1.2 million barrels, much more than expected.
The data added to earlier losses triggered by comments that Saudi oil production rose to 10.3 million barrels per day (bpd) in March, the highest monthly total on record.
