A “secret” release? How would that effect prices?
You need suppliers and purchases to know about addition oil to impact pricing.
If it were true, and I don’t think it is, the reason would be to affect voters’ minds more than actual oil prices..........................
Is the SPR filled with lower grade sour grade crude anyway bought at a higher price ?
Actually no better time than now then to get rid of the old crude that was sold at higher price and refill it with a higher grade at a lower priced.
