How is Iran benefitting 2x from its oil exports despite US bombing its export hub?

Iran raked in millions of dollars as it benefits twofold from its oil sales after the Strait of Hormuz's closure, despite the US bombing its oil export hub Kharg Island, Bloomberg reported. Iran's flagship crude grade is selling, mostly in China, at the narrowest discount to Brent crude in over 10 months. This comes as Brent itself surged above $100/barrel.
