Today’s Focus
Grain funds were mixed on Tuesday 13 October. The SOYB fund, which tracks soybean futures, fell 0.51% to US$27.33.
The WEAT wheat fund lost 0.74% to US$24.28, and the CORN fund added 0.11% to US$18.48. The broad DBA agriculture fund was almost unchanged.
We found no single driver for the moves. RT’s calendar listed no USDA crop or export-sales release for the day.
What matters today. Brazil and Argentina compete with US farmers in soybeans, so a softer US soy price matters to farm incomes across South America as well.
01 The session in one read
Soybeans and wheat edged lower on Tuesday 13 October, while corn was flat to slightly higher. The moves were small.
The dollar index fell 0.36% to 102.2. A weaker dollar usually helps US farm exports, yet the funds did not respond.
Small moves in opposite directions show a market waiting for news. No report or headline stood out.
The variable to watch is whether soybeans keep falling. A third down day would take SOYB below US$27.3.
02 The board
The funds are simple US-listed proxies for Chicago grain futures. They are not the cash price farmers receive.
Soybeans have now fallen on two days in a row, from US$27.53 on Friday to US$27.33, a loss of 0.73%. Corn was the only fund to rise.
| Asset | Level | Change |

| Wheat (WEAT fund) | US$24.28 | -0.74% |

03 What moved it
We found no single driver for Tuesday. RT’s calendar showed no USDA crop report or export-sales release.
In the absence of a scheduled report, traders often wait for weather and China purchase headlines. We could not confirm any such headline for the day.
04 The Latin American read
Brazil is the world’s largest soybean exporter, and Argentina is a leading exporter of soy meal and oil. Both compete with the United States for buyers in China and elsewhere.
US price moves feed through to Brazilian and Argentine farm incomes. Small moves on Tuesday meant little new pressure on either side.
05 The names to watch
The SOYB, CORN and WEAT funds are the simplest US-listed proxies for grain futures. They are not the cash price farmers receive.
Brazilian and Argentine exporters are not part of this board. For them, the local currency and freight costs matter as much as Chicago prices.
06 The outlook
Traders will look to the next USDA reports and to weather in the southern hemisphere. A firmer dollar would add pressure on US exports.
We could not confirm Tuesday’s settlement on the underlying Chicago contracts. We therefore quote the funds only.
07 What to watch
- Next USDA report: The agency’s crop and export data are the main scheduled drivers.
- Brazil’s planting: Southern hemisphere weather will shape the next soybean crop.
- US dollar index: A firmer dollar would add pressure on US exports.
- Chinese buying: Purchase headlines move soybeans most.
