Naval blockade fuels oil spike
U.S. statements about a blockade around Iran’s ports have pushed physical crude prices sharply higher, turning the Strait of Hormuz into a market-moving risk. Reuters reported prompt crude cargoes to Europe reached near $150 a barrel as the blockade fears grew, and NBC noted oil prices rose as markets digested the geopolitical threat and related comments. The surge is already being felt at the pump—AAA data cited by Spectrum showed U.S. average gasoline at about $4.12 a gallon this week. (reuters.com) (nbcnews.com) (spectrumlocalnews.com)
Oil traders are pricing a blockade around Iran’s ports as an immediate supply shock, and some physical crude cargoes to Europe are now changing hands near $150 a barrel. (reuters.com) (economictimes.indiatimes.com) The jump followed President Donald Trump’s statement that the United States would blockade ships entering or leaving Iranian ports after talks with Tehran failed. United States Central Command said the blockade began at 10 a.m. Eastern time on Monday, April 13, and would apply to vessels of all nations using Iranian ports. (nbcnews.com) (centcom.mil) Paper oil prices moved fast too, but not as far. Reuters reported Brent crude futures rose 6% to above $100 a barrel, while another Reuters market report said United States oil prices finished Monday up about 4% after earlier spikes. (economictimes.indiatimes.com) (usnews.com) The gap between futures and physical cargoes shows where the strain is landing first: refiners that need real barrels now. Reuters said prompt cargoes in Europe and Asia were trading far above benchmark futures as buyers scrambled for crude that does not depend on the Strait of Hormuz. (reuters.com) (staradvertiser.com) The Strait of Hormuz is a narrow shipping lane at the mouth of the Persian Gulf, and it carries about 20 million barrels a day of crude oil and oil products. The International Energy Agency said that was the average flow in 2025, and the United States Energy Information Administration said the route accounted for about one-fifth of global petroleum consumption. (iea.org) (eia.gov) That is why a blockade focused on Iranian ports can move prices well beyond Iran’s own exports. The United States military said ships traveling between non-Iranian ports could still transit the strait, but markets are reacting to the risk of disruption, retaliation, higher insurance costs and slower shipping through the corridor. (nbcnews.com) (centcom.mil) Iran called the action piracy and threatened retaliation, while Trump said American forces would respond to any Iranian “fast attack ships” that approached United States assets. Those warnings helped keep oil volatile even after futures pulled back from their intraday highs. (nbcnews.com 1) (nbcnews.com 2) American drivers are already seeing the first pass-through. AAA listed the national average for regular gasoline at $4.118 a gallon on Tuesday, April 14, and NBC reported the average was $4.12 on Monday after rising more than $1.20 a gallon since the war began. (aaa.com) (nbcnews.com) Analysts told Spectrum that gasoline prices are likely to rise again this week and diesel could follow unless shipping through the strait is restored. For now, the market is treating the waterway itself as the story, not just the oil fields behind it. (spectrumlocalnews.com) (iea.org)
