Grain and oilseed prices fall as markets trim Hormuz and Black Sea risk premiums
Global grain and oilseed prices declined as traders assessed possible geopolitical easing around the Strait of Hormuz and the Black Sea. Lower oil prices and favorable US weather added pressure, although shipping disruptions and crop risks remain.
Wheat leads broad agricultural decline
Global grain and oilseed prices extended their decline this week as traders reduced some of the risk premium associated with the Strait of Hormuz and Black Sea shipping, Terre-net reported. The move covered wheat, corn, soybeans and rapeseed, showing that expectations of geopolitical easing were affecting the agricultural complex rather than a single commodity.
In Chicago, wheat fell by 24 cents per bushel, or 3.5%, with the contract based on a 27 kg bushel. Euronext milling wheat dropped as low as €222 per tonne. US corn and soybeans each lost slightly more than 2%, while European rapeseed declined by 1.5%. Sébastien Poncelet, an analyst at Argus Media France, told AFP that grain prices had been broadly moving lower for more than a week.
Oil and shipping risks lose influence
A fall of more than 10% in oil prices over the period weighed heavily on agricultural markets, according to analysts cited by Terre-net. Corn and soybeans were directly exposed because both are widely used in biofuel production, but the selling spread into other crops. Poncelet said grains and oilseeds tend to follow oil when they lack stronger logistical or fundamental drivers of their own.
Markets also considered the prospect of renewed dialogue between Washington and Tehran after five months of war, raising hopes that an agreement could reopen the Strait of Hormuz. Donald Trump said on Tuesday that the strait would either open very soon or Iran would be hit very hard. Michael Zuzolo of Global Commodity Analytics and Consulting said traders appeared less willing than before to retain a risk premium in prices.
Black Sea demand and US weather reshape the outlook
A similar shift occurred in wheat linked to the Black Sea. Prices rose in July when navigation in the region was severely disrupted, but traders are now showing less concern and appear to expect an opening or another solution. Strikes between Ukraine and Russia nevertheless continue, preventing the loading of numerous wheat cargoes. Both countries rank among the world’s major wheat exporters, so unresolved shipping constraints remain relevant to physical supply.
The impact has been moderated by weaker demand from established Black Sea buyers. Turkey and Egypt have harvested near-record wheat crops this year and are currently relying on domestic supplies, Poncelet said. That distinguishes the present market from the price surge of 2022 and reduces immediate competition for disrupted export cargoes.
Crop conditions remain a counterweight
US weather provided another bearish influence after a period of heat in the western Corn Belt. August is crucial for soybean yields and for the grain-filling stage of corn. The US Department of Agriculture said recent showers, combined with temperatures near or below normal, had benefited both crops. Its weekly update nevertheless showed that corn quality had deteriorated while soybean conditions were stable, leading Zuzolo to identify buying interest in corn alongside selling in soybeans.
Weather risk has not disappeared. Europe has experienced several heatwaves, and French markets expect a record level of corn losses, according to Inter-Courtage broker Damien Vercambre. For producers and traders, the market now balances cheaper oil, reduced geopolitical premiums and subdued Black Sea import demand against continuing cargo disruption and uncertain harvest outcomes in the United States and Europe.
