Wheat Fund Falls 1.03% as Soy Fund Slips 0.76% | Grains, Oct 28

Grains daily market wrap.
Grains — the daily wrap.

Key Facts

  • The wheat fund WEAT fell 1.03% to US$22.12 and the soybean fund SOYB lost 0.76% to US$26.07 on Wednesday, October 28.
  • The corn fund CORN was almost flat, down 0.11% to US$17.42, while the broad agriculture fund DBA fell 1.06%.
  • Grain traders ADM and Bunge fell 1.24% and 0.55%, and the farm-economy fund MOO lost 0.71%.
  • There was no report from the USDA, the US Department of Agriculture, on the calendar for the day, so we show listed funds as labelled proxies.

Today’s Focus

Grain funds slipped on Wednesday, with wheat leading the decline. The wheat fund WEAT lost 1.03% to US$22.12, and the soybean fund SOYB fell 0.76% to US$26.07.

Corn was steady. The CORN fund eased only 0.11% to US$17.42.

The large farm-goods traders also fell: ADM dropped 1.24% and Bunge 0.55%.

What matters today. Brazil and Argentina compete with US farmers in soybeans, corn and meal, so softer grain prices help American food buyers and squeeze farm incomes in the Americas.

01 The session in one read

The broad agriculture fund DBA closed at US$27.11, down 1.06%. The VanEck agribusiness fund MOO fell 0.71% to US$80.26.

Among single names, ADM closed at US$77.23, down 1.24%, and Bunge at US$100.80, down 0.55%.

We did not have a verified futures price for the session, so we show US-listed funds and companies as proxies.

Assessment — A soft day for grains MEDIUM

All the proxies except corn fell by around 1%, which points to mild selling across crops. With no USDA report on the calendar, we cannot attribute the move to a specific data release.

The variable to watch is the next USDA export-sales and crop-progress data, which set the tone for soybean and corn prices.

02 The board

The funds hold futures, so they are a directional guide and not a mirror of the cash price. The wheat fund fell the most.

The traders ADM and Bunge fell with the crops. Both buy, store and ship grain from the United States, Brazil and Argentina.

The session read
The Ibovespa eased 2.68%, with breadth negative — 0 of 3 names higher. MERVAL led, while IPC MEX lagged.

03 What moved it

There was no USDA grain release on 28 October. The macro news was the decision of the US Federal Reserve, the US central bank, to hold rates at 3¾% to 4%, with two voters preferring a quarter-point rise.

The dollar index slipped 0.16%, yet grains still fell.

We could not confirm a weather or trade headline for the day.

04 The Latin American read

Brazil is the world’s largest soybean exporter and the United States the second-largest. The real was little changed at about R$5.35 per US dollar on Wednesday.

Argentina is the world’s top exporter of soybean meal and oil. Its Merval fell 1.30% and its official peso stayed at ARS 1,560 per dollar.

05 The names to watch

ADM and Bunge are the cleanest US-listed plays on global grain trade. Their shares often move with crop margins and with Brazil’s and Argentina’s export flows.

The MOO fund is broader and includes seed, fertiliser and machinery companies.

06 The outlook

Grain prices are likely to follow the dollar and the next USDA data. Brazil’s planting progress and Argentine export taxes are the main South American swing factors.

For US readers, softer grains help food costs but weigh on farm incomes.

07 What to watch

  • USDA export sales: Weekly data show demand for US soybeans and corn.
  • The dollar: A stronger dollar would pressure US exports.
  • Brazil’s planting: Weather and pace will shape the next crop.
  • Argentine policy: Export taxes affect farmers’ selling.

Frequently Asked Questions

Why did grain funds fall on Wednesday?

The wheat fund fell 1.03% and the soybean fund 0.76%. We could not confirm a specific trigger, and no USDA report was scheduled.

Who are the biggest soybean exporters?

Brazil is the largest and the United States the second-largest.

What do the grain funds track?

They hold futures for wheat, soybeans or corn, so they follow the direction of prices but not exactly the cash price.

Is there a grain futures price in this report?

No. We could not verify a futures price for the session, so we show listed funds and companies as labelled proxies.
