Delays in freeing a mammoth container ship stuck in Egypt’s Suez Canal have highlighted still more pressure points in global trade, a year after supply chains were disrupted by the pandemic.

Tugboats and salvage crews took advantage of high tides early today to partially refloat the Ever Given, which carries cargo between Asia and Europe. Shoei Kisen, the Panama-flagged ship’s Japanese owner, said the bow had moved slightly but was still touching the seafloor, and it was unclear how long it would take to fully reopen the canal.

The ship has been lodged in a single-lane stretch of the canal for nearly a week, blocking traffic through the critical trade gateway. Earlier, it was feared the Panama-flagged, Japanese-owned ship might be stuck for weeks.

Economists say the Ever Given’s disruption of shipping through the Suez Canal probably won’t have an impact on global trade for more than a few weeks, and is unlikely to derail global growth this year as more people get COVID-19 vaccines and economies reopen.

But it’s another wake-up call for companies that have set up their business to rely on supply chains with little room for error, said William Lee, chief economist at the Milken Institute.

“This is a warning about how vulnerable our supply chains are and how the just-in-time inventory techniques that have been so popular have to be rethought,” he said.

“The shortages and the supply chain shortages that cause assembly lines to shut down — that will have a greater impact,” Lee added.

Many countries got a harsh lesson in those realities last year when commerce, was disrupted in myriad ways after new coronavirus outbreaks began in China, the world’s factory floor.

Consumers everywhere soon found that ordering online was an adventure in the unknown, with many factories shut down and trade between Chinese provinces stalled. Obtaining supplies of medicines and vital personal protective equipment such as face masks and other medical supplies became challenging, and sometimes impossible.

Ships already are having to detour around the Cape of Good Hope in South Africa to avoid the canal. That slows the arrival of containers at their destinations and when they can be emptied and then refilled with other goods bound somewhere else. That can drive up costs — price increases that eventually reach consumers.

“Shipping prices are going to go up,” said Gary Hufbauer, nonresident senior fellow at the Peterson Institute for International Economics. “That will tighten up supply lines and mean shortages at the consumer level, and it will also mean somewhat higher prices for oil.”

The incident is another ripple worsening shortages of shipping containers in Asia, which means retailers may be late getting TVs, furniture, clothes, auto parts and many other goods that are shipped via containers.

About 12 percent of global trade by volume goes through the Suez Canal, but it accounts for 30 percent of the world’s daily shipping container freight. That makes it the most important conduit for trade between Europe and Asia. Some 19,000 vessels passed through the canal last year, according to official figures.

Lee of the Milken Institute points to the semiconductor industry as an area especially vulnerable to disruptions from shipping delays and is already plagued by shortages. Companies in Europe often get the components they need to make computer chips from suppliers in Asia.

“The shortage of semiconductors right now is so severe, that kind of delay in supply, even by a week or two, could also lengthen the delays in semiconductor production, which has stalled automobile and other electronics’ production,” Lee said.

The closure also affects oil and gas shipments. Nearly 10 percent of oil shipments and 8 percent of global liquid natural gas moves through the Suez Canal, according to the U.S. Energy Information Administration.

Much of the traffic involves transpiration of crude oil from the Middle East to Europe and the U.S. It’s also become an important link for Russian oil to Asia.

The disruption from the canal blockage comes at tricky time for international trade and shipping, noted Fiona Boal, global head of commodities at S&P Dow Jones Indices.

“The cost of shipping goods from Asia to Europe hit a record high in recent months and global freight rates are already near three times the level of a year ago,” she said.

At the same time, oil prices may be kept in check by worries that demand for oil will weaken amid renewed pandemic lockdowns in Europe. Benchmark U.S. crude oil for May delivery fell $1.03 to $59.91 per barrel today after rising $2.41 on Friday. Brent crude oil for May delivery lost $1 to $63.43 per barrel after gaining $2.62 on Friday.

North and Latin America are likely to be less affected than Europe by the blockage in the Suez Canal, because much of the shipping container traffic that runs between the Americas and Asia moves through the Pacific to hubs like the Ports of Los Angeles and Long Beach, or crosses through the Panama Canal.

“The impact on the U.S. will be less than on Europe,” Hufbauer said.
