[edited for typos/grammar] The US was going to top up the strategic reserves, but that was stopped in congress. Seems like an ideal time to make that happen with such low prices. Irregardless of environmental concerns, nobody is at a point where they are not dependent on oil and a supply disruption that this is designed to address currently would have dire consequences without it. IE: food shortages etc..
If top US leadership was less demented, they could secretly "buy" up all of these $-35 May contracts and get paid 35 dollars a barrel to put it in the strategic reserve.
But if such an agreement had been made in Congress and the US was obligated to buy at a certain (positive) price, you can bet the price wouldn't be $-35 right now.
