Since when is the United States, a sovereign nation, under ANY obligation whatsoever to notify a globalist bullshit agency with zero impact on the U.S., about what the U.S. does with its own oil?
It's probably part and parcel with being a member nation in OPEC, if I had to hazard a guess.
It sounds like the organization might be trying to manage the oil market, to ensure producing nations aren't sitting forever on stocks waiting to be shipped and consuming nations aren't running out waiting for their next shipment to come in.
