American farmers are finding themselves forced to the sidelines of the global food supply chain. The U.S. agricultural juggernaut is being overtaken by booming harvests in developing countries like Brazil, which controls 43% of the export market for soybeans, up from 12% in the late 1980s, and is close to surpassing the U.S. in corn exports, the WSJ's Jesse Newman and Jacob Bunge write. That gives Brazilian farmers greater sway over prices. It also means U.S. growers increasingly make decisions about what to plant and when to sell their harvest based on weather, transportation snarls and other events in faraway places. In this they join U.S. manufacturers and other industries that long ago lost their ability to sway the global market. The shift affects more than just farmers, as rural communities depend on tax revenue and the value of farmland to pay for local services.

Wal-Mart Stores Inc. is putting pressure on its food suppliers as it wages a price war in the grocery aisles. The retailer is aggressively cutting grocery prices in a bid to fend off low-cost brick-and-mortar rivals like Aldi and emerging online competitors, including Amazon.com Inc., the WSJ's Heather Haddon and Sarah Nassauer report. Consumers are coming out the winners, with shoppers paying 1.3% less for eggs, meat and other staples last year, the steepest drop since 1959. But it's squeezing profits at Wal-Mart and otherlarge grocers like Kroger Co., which must also slash prices to hold onto customers. The chains then pass some of the pain along to vendors. Low commodity prices have cushioned the blow, though some analysts expect agricultural markets to turn higher soon.

A trade dispute over steel is heating up. The Trump administration says it's investigating whether steel imports pose a national-security threat, potentially laying the groundwork for new tariffs against China. President Donald Trump, who campaigned on bringing back jobs lost as steel mills and other industrial plants succumbed to foreign competition, said that steel is too critical a resource for the U.S. "to become dependent on foreign countries." U.S. presidents can limit imports on national-security grounds, though they have rarely done so, instead relying on anti-dumping laws that bar foreign manufacturers from exporting products to the U.S. at below cost. Commerce Secretary Wilbur Ross called such rules too "porous." The steel probe is still in early stages, and similar studies in other industries this year haven't led to concrete action. But the stakes are high, as efforts to cut steel imports could spark retaliatory measures targeting U.S. exports.

RAILROADS

Hunter Harrison promises changes big and small at CSX Corp. In his first public remarks as the railroad's new chief executive, Mr. Harrison outlined plans for sweeping changes, including idling over 500 locomotives and 25,000 railcars and untangling the "spaghetti bowl" of intertwined East Coast routes, the WSJ's Paul Ziobro writes. CSX is already baking reforms into its earnings outlook, predicting profits will rise 25% this year, well beyond Wall Street forecasts. CSX earlier reported a jump in revenue and profits on stronger coal volumes. CSX shares were up 6% after Mr. Harrison spoke, a sign that investors believe the 50-year industry veteran can repeat the success he had in his previous post at Canadian Pacific Co.
