Note that this is for the May contract, which closes tomorrow, and anyone left with a contract then will have to actually take delivery of the physical product. Since we are in supercontango (oil storage is full, causing spot prices to be significantly lower than forward prices), I am guessing that traders who are still holding on to contracts and don’t have available storage have to unload contracts pretty quickly.…
What I don't understand is why the sudden move today? Did the longs think they had a place to put the oil on Friday but found out over the weekend they had no place to put it? Just seems like you would know what to do with the oil on Friday. Note this is not a rhetorical question, I would sincerely like an answer.
Now if you are a financial participant you need to close out your position as you are not in a position to either deliver/receive physical oil - so you need to essentially pay whatever it takes to close out the contract. In normal times there is plenty of storage and physical participants that are willing to provide liquidity as the contracts come to maturity. Now imagine you are a physical participant, and now space is limited/storage is expensive/ natural buyers aren’t buying (refiners) - you are not going to pay much to buy the oil of a financial participant who needs to sell the May contract to roll into June/July...
