Oil jumps as Hormuz uncertainty tightens supply
Crude prices surged toward $100 a barrel after fresh uncertainty over Strait of Hormuz access and ongoing Middle East hostilities, squeezing shipping and energy‑intensive supply chains. That spike is already showing up in higher transport and input costs and is a likely driver of the recent CPI uptick. (edition.cnn.com) (newsable.asianetnews.com)
Oil does not need a full blockade in the Strait of Hormuz to get expensive. On April 10, ship traffic was still in single digits even after a two-week ceasefire, with more than 600 vessels, including 325 tankers, still stranded in the Gulf. (aljazeera.com) That one waterway is only 29 nautical miles wide at its narrowest point, and the usable shipping lanes are just 2 miles wide in each direction. In 2025, about 20 million barrels a day of oil and oil products moved through it, which is roughly a quarter of global seaborne oil trade. (iea.org) Most Gulf producers cannot simply reroute around it. The International Energy Agency says only 3.5 million to 5.5 million barrels a day can be diverted onto alternative pipelines, far short of the nearly 20 million barrels that normally leave through the strait. (iea.org) The market has been trading that gap in real time. Reuters reported on April 8 that oil had briefly fallen below $100 on ceasefire hopes, and by April 10 prices were climbing again as traders saw that tanker traffic had not actually normalized. (msn.com) (aljazeera.com) The reason prices jump so fast is simple: oil is priced on expected deliveries, not just barrels already on ships. When insurers, shipowners, and refiners start assuming delays, they bid up cargoes the way grocery stores would bid up milk if the only highway into town looked unsafe. (eia.gov) (aljazeera.com) This is not only an oil story. The same route carries about 19 percent of global liquefied natural gas trade, largely from Qatar and the United Arab Emirates, so power markets and industrial fuel buyers get hit at the same time as refiners. (iea.org) For the United States, the first visible effect is usually gasoline. The Bureau of Labor Statistics said the Consumer Price Index rose 0.9 percent in March 2026 and 3.3 percent over 12 months, while CNBC’s read of the report said gasoline jumped 21.2 percent in March and accounted for nearly three-quarters of the monthly headline increase. (bls.gov) (cnbc.com) The second effect is freight. If tankers queue up, fuel costs rise for trucking, air cargo, plastics, chemicals, fertilizer, and any factory that burns a lot of energy, so the shock moves from the pump into shelves, packaging, and shipping invoices. (eia.gov) (iea.org) Asia feels the direct squeeze first because about 80 percent of the oil moving through Hormuz is headed there, and China and India alone took 44 percent of the strait’s crude exports in 2025. That means a traffic jam off Iran quickly becomes a cost problem for Asian refiners, then for global diesel, jet fuel, and manufactured goods. (iea.org) So the real headline is not just “oil near $100.” It is that a narrow channel between Iran and Oman is still moving only a fraction of its usual 120 to 140 daily transits, and until that number looks normal again, every ceasefire headline will be competing with the harder evidence on ship trackers.
