More Rain Forecast
“Soybeans and corn are being pushed down by forecasts of more rain in Argentina which will be very welcome for Argentine crops after drought which has been a major factor in the market in past weeks,” said Matt Ammermann, StoneX commodity risk manager.
“With more rain forecast in Argentina in coming days, we may start to see a feeling in the market that the drought risk to Argentine crops has now been priced in and maybe some risk premium should now be removed.”
Forecasts are for more rain in Argentina both this week and next week.
“We could start seeing more focus on the generally bearish fundamentals in the soybean market, with a record crop expected in Brazil,” Ammermann said.
“China is celebrating the Lunar New Year so we are unlikely to see supportive buying by the Chinese this week. China is anyway switching its import purchasing to Brazil’s new crop.”
Along with spillover weakness from corn and soybeans, wheat is also facing pressure from a good mix of rain and snow in the U.S. southern Plains which is positive for U.S. crops, he said.
“The small spread between wheat and corn prices is also gaining attention," Ammermann said. "Some will say either wheat is too cheap or corn too expensive.”
