Shipping traffic through the Strait of Hormuz slowed on Monday after Iran threatened to retaliate against any new U.S. attacks. Kpler data showed seven commodity vessels transited the strait, down from eight the previous day. Iran had warned that energy infrastructure across the Gulf, including U.S. oil and gas interests, was vulnerable. Goldman Sachs raised its Brent and West Texas Intermediate crude oil price forecasts for December 2026 and 2027, citing expectations that Middle East shipping disruptions would continue into next year. Traffic through the Bab el-Mandeb strait moved in the opposite direction, with 29 commodity vessels passing on Monday compared with 17 the previous day. The figures may exclude vessels traveling through either strait with their transponders turned off.
