Brazil soybean meal export basis falls to widest discount to Argentina since Jan

Brazilian soybean meal export differentials fell to their widest discount to the competing Argentine product since January, pressured by congestion at the port of Paranagua, improving domestic crush margins and a more favorable outlook for the soybean crop currently being planted.

Platts, part of S&P Global Energy, assessed the FOB Paranagua soybean meal basis for December loading at a $16/short ton premium to Chicago Board of Trade futures on Oct. 21, $10/st below the FOB Up River differential. The discount for Brazilian meal against Argentine product was the widest since Jan. 21, when it stood at $11/st.

In outright price terms, Platts assessed FOB Paranagua soybean meal at $401.57/metric ton, compared with $412.59/mt for FOB Up River product.

Argentine soybean meal typically trades at a discount to Brazilian product due to geographic and logistical factors. Argentina's main export terminals are located along the Parana River, where draft restrictions limit the loading capacity of larger vessels such as Panamax ships.

That relationship, however, shifted during October amid persistent rainfall around the port of Paranagua, Brazil's main soybean meal export hub. Adverse weather has disrupted loading operations, according to market sources.

"There are vessels facing delays of 40 days [to load]," an analyst said.

"The lineup is heavy," a trader said, adding that demurrage costs have contributed to the pressure on export premiums.

Platts had assessed the FOB Paranagua soybean meal basis at a $31/st premium to CBOT futures on Oct. 14.

Preliminary data from Brazil's Foreign Trade Secretariat showed soybean meal exports totaling 1.10 million mt in the first 11 working days of October, out of 22 working days in the month, up 19% week over week and 3% year over year. If that pace is sustained through the end of the month, exports would reach roughly 2.30 million mt, above S&P Global Energy CERA's current forecast of 2.19 million mt.

Beyond congestion at Paranagua, other factors have also weighed on Brazilian soybean meal export premiums, including an improvement in domestic crushing economics, as margins had remained at less attractive levels in August and September.

The Brazil Soybean Crush Spread, a synthetic crushing margin calculated by Platts, was assessed at $38.33/mt on Oct. 21, compared with levels around $12/mt in August and $17/mt at the beginning of September.

A more favorable outlook for Brazil's 2026-27 soybean crop has added further pressure. Earlier concerns that El Niño could negatively affect the crop have eased as planting advances, with more than 20% of the projected area now planted.

"El Niño does not appear to be bringing the dry weather to central Brazil that was previously anticipated, and downside risks to Brazil's production are diminishing as planting progress accelerates," CERA analysts said in the Global Soybean Complex Short-Term Outlook, published Oct. 16.

CERA currently forecasts Brazil's 2026-27 soybean production at 177 million mt. Brazil is the world's second-largest soybean meal exporter, behind Argentina.
