Companies from the Swedish furniture giant Ikea to Illinois-based Caterpillar Inc., the global maker of construction equipment, are among the customers of ocean freight weighing alternative sourcing plans. In the short term, the added stress on trade will translate into higher transportation costs, tighter supplies, and more delivery delays for producers and purveyors of goods. Even before the incident that closed the Suez, input costs in the euro area rose at the fastest pace in a decade, while measures of prices paid and charged by U.S. businesses advanced in March to fresh records as shortages of materials and disrupted supply chains sparked inflation concerns. Over the longer run, it may force a rethinking about the dangers of too much globalization and of supply chains exposed to too much unforeseeable risk. Overestimating those dangers might be a mistake, though, said Robert Koopman, chief economist of the World Trade Organization in Geneva.
