In 2023, traffic in the port of Marseille Fos decreased -7% to 71.9 million tonnes compared to 77.3 million tonnes in the previous year. In the sector only of containers, with 12.1 million tonnes, volumes fell -11%, a decrease of -13% in terms of 20-foot containers handled, having been equal to more than 1.3 million TEUs. Ro-ro traffic, with a total of 218,000 trailers, it has shrunk by -9%. In the liquid bulk segment, the traffic remained stable at around 45 million tonnes, while in the dry bulk sector it was recorded a sharp decrease of -24% as they were handled 8.7 million tonnes, a reduction also due to the downtime for four months of a blast furnace at the ArcelorMittal plant in Fos as a result of the decline in steel demand that led to a significant contraction in the company's imported raw materials which fell by -22% to 5.8 million tonnes.

Last year passenger traffic in the French port, of around four million people, marked an increase in +36%, with an increase of +76% in cruise passengers to 2.5 million units and a decrease of -2% in passengers of regular shipping lines.
