And OPEC immediately counter-punched, lowering their output MORE than anticipated. So really, it doesn't mean a damn thing. We will be paying the same, or more, at the pumps. Trump had been asking them to keep it the same so prices would lower with the new US production, but they voted against that, with Saudi Arabia making the biggest cuts. Russia (not in OPEC) cut back as well. So, it seems it's a net loss for the consumers, but great for oil companies.
