Hormuz blockade shocks markets
The U.S. plans to block maritime traffic to and from Iranian ports through the Strait of Hormuz starting Monday, and that announcement has pushed oil above $100 a barrel and unsettled markets. Investors are already pricing in stagflationary stress as oil climbs and equities slide, with analysts warning the combination of a shipping choke-point and tariff threats could amplify global trade and inflation risks.

Oil jumped above $100 a barrel on Monday after President Donald Trump said the United States would begin blockading traffic to and from Iranian ports through the Strait of Hormuz. (cnbc.com) ABC News reported the blockade was due to start at 10 a.m. Eastern time on Monday, April 13, after weekend talks between Washington and Tehran in Pakistan failed. Reuters reported Brent crude rose about 7.3% to $102 a barrel in early trading. (abcnews.com, usnews.com) Stocks fell as traders moved out of riskier assets. Reuters said Australia’s S&P/ASX 200 dropped 0.4% to 8,925.60, while ABC News said oil’s surge pushed energy shares higher and weighed on the broader market. (businesstimes.com.sg, abc.net.au) The Strait of Hormuz is a narrow shipping lane between Iran and Oman that carries about 20 million barrels of oil a day. The United States Energy Information Administration said that was about 20% of global petroleum liquids consumption in 2024. (eia.gov) That makes any military move there a direct threat to fuel supply, shipping insurance and refinery costs far beyond the Gulf. Reuters said investors were also selling bonds and buying dollars as they braced for slower growth and higher prices at the same time. (eia.gov, newsbreak.com) The blockade order is narrower than a full closure of the strait. United States Central Command said it would be enforced against vessels entering or leaving Iranian ports, not all shipping using the waterway. (usatoday.com) Iran called the move illegal. The Hindu reported Iranian military officials said a United States naval blockade in the strait “amounts to piracy,” while Trump said the breakdown in talks left Washington no deal to announce. (thehindu.com, cnbc.com) Shipping disruption has been building for weeks. Reuters reported on April 11 that three fully laden supertankers were among the first vessels to exit the Gulf after an earlier interruption, showing how closely traders were already tracking every transit through the chokepoint. (msn.com) What happens next depends on whether the blockade stays limited to Iranian trade or triggers retaliation that hits the wider waterway. For markets, Monday’s first signal was simple: pricier oil, weaker equities and a fresh scramble to price geopolitical risk. (usatoday.com, newsbreak.com)
