“President Trump warned Putin that he would decimate the price of Russian oil.”
Overseas markets (Asia) have already reopened after the weekend, and oil prices have resumed their fall - down about another 4% so far today. WTI just cracked below $60, Brent under $63.5.
Russian Urals and ESPO grades are no longer openly traded or prices reported in real time, but would be expected to be falling roughly proportionally, with their discount to Brent.
And Putin has to sell it to China and India at an additional 30% discount. The oil income freefall for Russia continues.
