Hormuz blockade risks widen

The U.S. blockade in the Strait of Hormuz is no longer just a U.S.-Iran fight; it is now hitting China’s oil trade and India’s energy security. (cnbc.com) President Donald Trump ordered the naval blockade on April 12, and the White House said on April 15 that it was “fully implemented.” CNBC reported the action targets vessels entering or leaving Iranian ports and coastal areas around the strait. (cnbc.com, cnbc.com) China reacted on April 15 by calling the blockade a “dangerous and irresponsible act,” while Foreign Ministry spokesperson Lin Jian denied reports that Beijing was giving military support to Iran. Lin also warned Washington that China would answer any tariff increase with countermeasures. (cnbc.com, hindustantimes.com) India is being pulled in from the other side of the market. Reuters reported on April 15 that the Iran war has disrupted shipping routes and raised energy costs for India, even as March exports to the United States helped narrow its merchandise trade deficit to $20.67 billion. (reuters.com) The strait matters because it is one of the world’s tightest oil chokepoints. The U.S. Energy Information Administration said 20 million barrels a day moved through Hormuz in 2024, equal to about 20% of global petroleum liquids consumption, with few practical alternatives if traffic is blocked. (eia.gov) That makes Asia especially exposed. The International Energy Agency said Asia is the main center of oil demand growth and attracts a growing share of supply from the Middle East, including shipments to India and other Asian refiners. (iea.org) China’s exposure is direct because much of Iran’s oil has been flowing to Chinese buyers. CNBC reported the blockade is squeezing Iran’s exports at the same time that Beijing is trying to avoid being cast as Tehran’s military backer. (cnbc.com, hindustantimes.com) India’s position is different but still fragile. Reuters reported on April 4 that Indian refiners had made their first Iranian oil purchase in seven years as the conflict disrupted supplies through Hormuz, and other buyers have also been scrambling for replacement barrels. (reuters.com, msn.com) The U.S. says the blockade is cutting off Iran’s seaborne trade, not closing the whole waterway. CNBC reported that more than 90% of Iran’s $109.7 billion in annual seaborne trade passes through Hormuz and that maritime tracking still showed some limited movement by sanctioned or high-risk vessels on the first full day of enforcement. (cnbc.com) What happens next depends on whether sea traffic stays limited or broadens again under talks with Tehran. For now, the blockade has turned a narrow military move into an Asia-wide test of oil flows, shipping risk, and U.S. ties with Beijing and New Delhi. (cnbc.com, msn.com)
