EU GMO detection reports pressure Argentine meal basis, fuel CBOT's rally

Reports that the European Union detected shipments of Argentine soybean meal with traces of genetically modified material not authorized by the bloc shook the market on April 27, boosting futures on the Chicago Board of Trade and pushing FOB Up River port differentials to nearly two-month lows.

According to Argentine media, European importers issued at least three alerts about traces of the genetically modified event HB4 in shipments of Argentine soybean meal that arrived in the Netherlands. HB4 is not approved in the EU, which raised fears about potential shipment rejections and halting exports.

The issue is sensitive for Argentina, since the country is the world's largest exporter of soybean meal, with shipments projected at 29.50 million metric tons in the newly started 2025-26 marketing year (April-March), according to S&P Global Energy CERA.

As a direct consequence of the news and subsequent fears regarding demand for the Argentine product, the country's port differentials for soybean meal exports weakened considerably.

On April 27, Platts, part of S&P Global Energy, assessed the basis for FOB Up River soybean meal for June delivery at a $7/short ton discount to the CBOT benchmarks. It was the lowest level for a spot shipment since March 7.

"Nobody knows the consequences this can have, but it might put basis down and CBOT up," an Argentina-based broker said, adding that the improving harvest progress in the country also weighed on spot differentials.

Rising prices

In fact, while basis levels for Argentine soybean meal exports fell, FOB prices advanced, supported by the jump in CBOT futures.

The CBOT July (N) contract rose nearly 3% on April 27, settling at $327.80/st, contributing to the FOB Up River outright price for June rising $5.18/st to $353.62/mt.

Overall, the assessment among some market participants was that the Argentina-EU situation could redirect the European bloc's demand for soybean meal to the US if the issue escalates.

"I think there are people in the market who think that, and that probably added fuel to the soybean meal [CBOT] rally," a trader in the CIF New Orleans market said. "But it is likely a fairly isolated event is my guess."

"If this gets bigger, then potentially [could generate demand for US meal]," a second trader in the CIF NOLA market said. "But right now it is not that much of an issue. No EU buyer is talking about switching to the US yet. I would think that the EU would fix its regulations before they switch more demand to the US."

This happens amid a tight US soybean meal market and the crushing plant maintenance season, a situation that "is definitely going to drag through May," the second trader added.

"Soybean meal basis increased a lot yesterday [April 27]," a US feed trader said. "I heard shipments of soybean meal going to Europe were rejected because of a GMO trait in Argentina and Brazil, so it's possible that Europe is trying to buy soybean meal from the US," the trader said, referring to the recent soybean meal rally.

A broker also added on the situation: "Soybean meal has been firm and firming front end once again. Anything is possible at this point," referring to the possibility of the EU buying product from the US.

Destination side

Argentine media reported that the local industry is working to minimize damage, while the Argentine government and Bioceres, the biotech developer, claim they have not received official confirmation of these detections.

The Argentine Chamber of Grain Exporters and Processors (CIARA-CEC) did not respond to a request for comment from Platts.

The EU is the leading importer of soybean meal from Mercosur countries, particularly Brazil and Argentina.

According to European Commission data, in the 2025-26 marketing year, from July to February, Brazil supplied 7.18 million mt and Argentina 4.59 million mt of soybean meal to the EU, together accounting for 85.4% of total imports.

Italy, the largest importer of Argentine soybean meal, received 1.03 million mt from July 2025 to February 2026, which represented 22.5% of total imports.

A trader in Italy noted that, while no incidents involving unapproved genes have been reported in the country, ports remain on high alert.

With soybean meal supply already under pressure and prices rising across the EU, this development has further increased prices and may push them even higher, according to traders in Italy and Spain.

Participants in Italy, Spain and the Netherlands added that import volumes from Brazil and Argentina vary across EU countries, but the issue could affect the entire region.

Platts assessed FOB Netherlands at Eur372.5/mt and EXW Spain Soybean meal at Eur382/mt on April 28.
