American shale drillers aren’t coming to the rescue of beleaguered energy markets anytime soon. Leaders of fracking companies say there are limits to how much and how quickly they can boost oil supplies following Russia’s invasion of Ukraine. The WSJ’s Collin Eaton writes that the drillers face supply-chain constraints, including shortages of equipment, labor and the sand used in fracking. Executives also caution that investors remain wary of overspending after shale drillers prioritized expansion over profits in the past decade. That suggests no imminent relief for the transportation sector after diesel prices skyrocketed nearly 75 cents a gallon over the past week. Still, oil prices have pulled back from recent breathtaking highs, and there are signs the drilling sector is stirring. Freight carloads on U.S. railroads in the category that includes fracking sand rose 36.3% in February from the year before, according to the Association of American Railroads.

Supply-chain congestion is wreaking havoc on seasonal shipping patterns. Retailers across the U.S. say they are still coming up short on inventories for key products, the WSJ’s Suzanne Kapner reports, including spring lines of shorts, sandals and other time-sensitive warm-weather gear. The dilemma extends a major headache for retailers during the past two years of supply-chain disruptions. Shipping backups have delayed delivery of targeted seasonal merchandise, from summer attire to Christmas decorations. That batters the value of the goods and fractures traditional patterns of ordering, shipping and selling behind supply chains. Many chains are placing orders with overseas factories earlier, and paying hefty sums to fly the goods to the U.S. But that isn’t necessarily solving the problem, and it ties up capital in inventory. And some shippers say domestic trucking has overtaken ocean transport as their biggest distribution headache this year.

Amazon is facing more heat in Washington. A congressional committee is asking the Justice Department to investigate the company and some of its executives for what lawmakers say is potentially criminal obstruction of Congress. The WSJ’s Dana Mattioli reports that Democrats and Republicans on the panel made the request this week in a letter to the U.S. attorney general. They say Amazon refused to provide information for an investigation of the company’s competitive practices, including its treatment of third-party sellers. Amazon denies the charge. The request escalates tensions between Amazon and lawmakers who issued a report criticizing the company and other tech giants, fueling legislative proposals aimed at curbing their power. The antitrust committee was looking at how Amazon uses the data of third-party sellers on its platform when creating private-label products, and how it treats those Amazon brands in its search results.
