Surging shipping costs to drive consumer price inflation, UNCTAD says

«UNCTAD’s analysis shows that the current surge in container freight rates, if sustained, could increase global import price levels by 11% and consumer price levels by 1.5% between now and 2023,» the UN report said Thursday.

By country, the U.S. would see consumer prices rise by 1.2%, while China would see a 1.4% increase, the report said. The analysis found that smaller countries more dependent on imports would see consumer prices rise by a much higher 7.5%.

By product, electronics, furniture, and apparel would see the greatest price increases — of at least 10% globally — due to supply chain distribution, UNCTAD said, noting containers account for 17% of total seaborne trade volume.

Some companies have chosen to send smaller products by air as a result of the soaring cargo shipping costs, although air freight tends to be more expensive.

The container shipping cost surge would also drag down growth in major economies, the analysis said.

Industrial production, a major driver of growth, is set to fall by more than 1% in the U.S. and euro area, and drop by 0.2% in China, if container freight rates rise 10% and supply chains remain disrupted, the report said.

As of late October, more than 600 container ships were stuck outside ports worldwide, twice the level at the start of the year, Swiss logistics giant Kuehne+Nagel told CNBC’s «Squawk Box Asia.» The company projected late last month that the congestion would last until at least February.
