The question of whether Iran will close the Strait of Hormuz, a vital global energy passage, has garnered considerable attention. Member of the Iranian Parliament's National Security Committee, Kousari, indicated that the parliament has suggested closing the strait, but the final decision rests with the Supreme National Security Council. If implemented, this blockade could disrupt approximately 20% to 30% of the world's oil supply, potentially affecting other U.S. allies as well.

The Strait of Hormuz connects the Gulf of Oman with the Persian Gulf and serves as the sole maritime route for oil exports from the Gulf region. The control of this strait is shared between Iran and Oman, with about 60% of China's crude oil imports relying on this passage. A blockade could compel China to activate its strategic reserves.

As the third-largest oil producer in the Organization of the Petroleum Exporting Countries (OPEC), Iran produces around 3.3 million barrels per day, with exports to China last month reportedly reaching 1.84 million barrels. However, following a U.S. missile strike against Iran, there is now a push for China to persuade Iran not to close the strait. Senator Rubio stressed that such a move would be economic suicide and called on other nations to address this threat.

The global financial market is also in flux. While China’s stock market remains largely unaffected, indices in Japan and South Korea have dipped, reflecting the instability of the diplomatic landscape. If Iran’s regime stability declines, there could be a likelihood of more extreme reactions.

As Israel struggles to manage the Iranian threat independently, it has resorted to requesting U.S. airstrikes on nuclear facilities, highlighting a state of diplomatic isolation.
