Argentina temporarily suspended its export taxes on grains, a measure that lasted less than 72 hours after reaching a US$7 billion inflow target. Chicago corn futures closed sharply lower the prior week at about $4.22 per bushel.
The temporary end of retenciones makes Argentine grain more competitive in export markets, pressuring CBOT corn and soybean prices and reducing demand for US product.
