FROeelin Wrong...?

It's actually as simple as:
1. refineries put off purchasing oil since they sometimes experience backwardation...=the cost of their material is higher than its derivitives...

2. refinery stockpiles run low and they need replenishment...

3. refineries hire tankers to replenish the dwindling supplies...

4. refineries raise prices and bank cash

5. start again at step 1

by the way - shippers are slowing their vessels to conserve fuel - so maybe my buoyancy compensation plan is a good idea - everyone grow a FRO, cut it, and throw it in the sea to help the ships glide along...
