# EU GMO detection reports pressure Argentine meal basis, fuel CBOT's rally | S&P Global

> European importers reported Argentine soybean meal shipments containing traces of the GMO event HB4, which is not authorized in the EU. The reports triggered rejection fears and pushed CBOT soybean futures nearly 3% higher on April 27. Argentine Up River meal basis fell to a two-month low at a $7/short ton discount to CBOT.

## Why it matters

Possible rejections of Argentine meal, the world's largest meal export flow, would shift EU demand toward US meal and widen Argentine export discounts. Buyers should expect firmer CBOT meal and soybean prices and weaker South American basis.
