Throughput at the Suez Canal Container Terminal (SCCT) has fallen by nearly a quarter between 2015 and 2016.
According to Cosco Pacific, which has a minority stake in the terminal, throughput has fallen 21% in the first six months of 2016 and 23% in June 2016.
SCCT is the biggest of the two terminals at Port Said in Egypt, at the Northern end of the Suez Canal, and is operated by APM Terminals.
The Suez Canal has been struggling to increase its volumes since it was expanded in August 2015.
The low oil price has increased the attractiveness, for certain routes, of going round the south of Africa to avoid the canal’s tolls.
In response, the canal has offered discounts to ships travelling between the East Coast of the Americas and Asia.
