Against the backdrop of these events, on the morning of March 12, there was a sharp increase in oil prices in the markets, which rose again to $100 per barrel, despite the International Energy Agency's decision to release 400 million barrels from strategic reserves.
The Iranian Revolutionary Guard Corps (IRGC) stated, as reported by BBC News, that "artificially restraining the rise in oil prices is impossible" and warned of the need to prepare for a level of "$200 per barrel."
