Iran attacks US military base in Qatar, causing oil prices to plummet. Why? The market is not afraid of sustained conflicts of moderate intensity. The market is afraid that Iran will really block the Strait of Hormuz. Now it seems that Iran has chosen to launch missiles instead of blocking the strait to counterattack. Naturally, the market's concern about the surge in oil prices due to the blockade of the strait has greatly eased. As for Iran's counterattack, it seems to be of moderate intensity as mentioned earlier. In fact, during the Iran Israel conflict two years ago, Iran also wanted to throw missiles at US military bases as a counterattack.
