If world supply is flat but demand is growing, how come global inventories are at very high levels?  High demand, flat supply should yield an inventory decrease, but it isn't.  Is part of the demand a recently expressed desire for hoarding oil?
First, only the US has high stocks, and US stocks would be no higher than last year if loans from the spr were repaid.

Second, world OECD stocks are at a ten-year low, maybe foreign buyers are waiting for falling oil/dollar, in which case current price might be attractive. IMO, the first sign of solid support will bring many buyers and strong bounce.
