Grain and oilseed traders were buffeted by volatile futures markets and exchange rates on Wednesday. But the full impact of the tariffs imposed by the US — a major net exporter of wheat, corn and soy — is only likely to emerge once other governments' responses become clear.
Wheat, corn and soybean futures were trading lower on the day when the Chicago Board of Trade opened on 3 April, the day after the US announced a swathe of import tariffs. But corn and wheat futures contracts began to recover hours later.
Canada and Mexico, which made headlines in the initial wave of tariffs from Trump's administration, were on the sidelines on 2 April. Both are covered by the United States-Mexico-Canada Agreement (USMCA). This means Mexico could remain an important outlet for US corn and wheat — for now. US corn sellers have relied heavily on Mexico to shore up sales this marketing year. Of the 54mn t of current-crop US corn sold for export this marketing year (September-August) as of 27 March, 19mn t has been for Mexico, US Department of Agriculture (USDA) data show. USDA sees US corn exports hitting 62mn t this marketing year.
Impact on Europe and Asia
Euronext wheat, corn and rapeseed futures also began trading down on the day. But a sharp fall in the value of the dollar against the euro meant bids and offers for EU wheat discussed in the physical market in dollar terms held more or less steady early today. The Interactive Data Corp exchange rate closed at €0.90630 to the dollar at midday in London on 3 April — the lowest since October 2024.
Ukrainian corn sellers are under particular pressure from a drop in the price of US commodities on certain markets, but could also stand to gain from a halt in deliveries of US corn to importers in Asia, before Brazil begins shipping its safrinha crop in July. Ukrainian corn typically competes with the US in Mediterranean markets, notably Spain, and in China. But Ukrainian corn has not been competitive against US corn recently — in the month since 3 March, when the US doubled tariffs on China from the 10pc introduced on 4 February, Ukrainian corn fob prices' premium to US corn fob Gulf has climbed, and in late March it hit its highest in Ukraine's current October-September marketing year, Argus-assessed prices show.
But there is no guarantee that buyers will pay up, at least not immediately. Chinese buyers have already distanced themselves from US corn and soybeans this marketing year.
Chinese buyers took little notice of Ukrainian corn sellers floating offers at above $270/t cif China on 2 April, immediately after the US announced an additional 34pc tariff on imports from China — bringing the actual rate to 54pc — and Beijing vowed retaliation. Chinese importers bid for Ukrainian corn in the $250s/t cif for July-August loading last week.
Chinese buyers could be exposed to hikes in Brazilian soybean prices — something that might be more likely if EU buyers book more soybeans from Brazil at the expense of US cargoes.
US soybean sales to China have already begun to slow. Chinese crushers have avoided US soybeans since December because of uncertainty over trade relations. Shipments to China dominated US vessel line-ups in late March, with exporters sending 641,000t to China on 21-27 March alone. Some 600,000t of corn was sold but not yet shipped as of 27 March, compared with 1.6mn t still to ship at the same point last month, weekly USDA data show.
