Maersk, which controls about one-sixth of the world’s container trade, and its peers have benefited from supply-line disruptions as a shortage of shipping capacity has enabled them to charge higher prices for their services.

Hapag-Lloyd AG, the world’s fifth-largest shipping line, on Thursday raised its profit forecast saying average freight rates have been about 80% higher in the first half of 2022.

Underlying earnings before interest and tax will be around US$31 billion in 2022, the Copenhagen-based company said on Tuesday. That compares with a previous forecast of around US$24 billion and an average estimate of US$28.4 billion in a Bloomberg survey of analysts.

“Congestion in global supply chains leading to higher freight rates has continued longer than initially anticipated,” Maersk said. “The strong result is driven by the continuation of the exceptional market situation.”

Maersk shares, which jumped more than 70% last year, were little changed in Copenhagen trading after earlier climbing as much as 3.7%.

“The average container rate still remains significantly above historical levels which bodes well for the profit outlook for 2023,” Brian Borsting, a credit analyst at Danske Bank, said in a note. “Macro uncertainty and a high container order book are main risks.”
