Market participants expressed anxiety over oil supply amid the ongoing conflict between Iran, the United States, and Israel. Crude oil prices have surged more than 38% in less than two weeks due to serious threats to global supply routes.
Brent crude reached USD 100.72 per barrel, whilst West Texas Intermediate (WTI) stood at USD 95.37 per barrel.
The surge was driven by attacks on two oil tankers and an oil port facility in Iraqi waters, which triggered concerns over navigation safety in the Strait of Hormuz. Iranian military officials have even warned that oil prices could soar to USD 200 per barrel.
In another development, amidst large-scale military operations launched by the United States and Israel, US intelligence indicates that Iran’s current government leadership structure remains intact and far from facing collapse. The report confirms that the Tehran regime maintains full control over its population.
The position of supreme leader has also been assumed by Khamenei’s son, Mojtaba, to maintain stability. On the other hand, the Kurdish Iranian militia group offered to assist in an uprising, but this option was rejected by President Donald Trump, as intelligence doubts their weapons capacity.
According to latest reports, Mojtaba stated in his first public address since being selected as Iran’s supreme leader that the Strait of Hormuz must remain closed, implementing this as a tool to pressure adversaries.
