RE:RE:NDP$80-$85 is the estimate for a balanced budget for SA according to this article: https://oilprice.com/Energy/Oil-Prices/Sources-Saudis-Admit-They-Want-70-Oil.html
It's a delicate balancing act, however, as Trump prefers $60-$65. So $70 seems like a friendly compromise.
$100 oil wouldn' be good for anyone except short-term stock and futures traders.
If the seasonal pattern holds, we should see higher prices through September.
