The United States began a naval blockade of Iran on Monday at 14:00 GMT to pressure Tehran economically. Iran's armed forces called it illegal piracy. Iran exports 80 percent of its oil through the Strait of Hormuz, earning $4.97 billion monthly recently—40 percent more than pre-war February. The blockade directly threatens these revenues. Iran holds approximately 157.7 million barrels of oil on water, 97.6 percent destined for China. Experts warn significant economic damage ahead.
