Japanese refiners are seeking faster deliveries of US crude by chartering smaller tankers that can use the Panama Canal, rather than sending larger ships on longer voyages around Africa. The shift shows how buyers are still redesigning supply chains even after the US-Iran truce, aiming to cut transit time and reduce exposure to disruptions that recently hit Middle East flows and forced importers to rethink cargo timing.
TankerMap data shows how this rerouting logic fits the wider market. The platform tracks 3,201 crude tankers and 155 energy ports globally, including 36 oil export ports and 26 oil import ports. Live vessel data on Wednesday showed crude tankers active across alternative routes, including MARETA underway in the eastern Mediterranean, ALATAU near Gibraltar and BELMAR moving westbound, illustrating how fleet deployment is spreading across Atlantic and Mediterranean corridors as refiners search for more flexible crude supply options.
