<h1>Iran threatens Strait of Hormuz closure amid strike concerns affecting global oil supplies</h1> US strikes on Iranian nuclear facilities raised concerns about potential Strait of Hormuz closure, through which one-fifth of global oil and gas flows. The nation imports 2 million barrels daily through the strait but has diversified sources including Russia, US, and Brazil as alternatives. Russian oil bypasses the strait entirely, while gas supplies from Qatar don't use this route. Despite historical threats, Iran has never closed the strait due to strategic costs and would harm its own exports. Oil prices could reach $80-90 per barrel if disrupted, but analysts consider prolonged closure unlikely given US naval presence and Iran's economic dependence on the waterway.
