Grains: Wheat, Corn and Soybeans Daily — 2026-09-28
Top developments
Wheat heads for fourth straight weekly loss on Black Sea export hopes
CBOT wheat was down 2.1% at $6.92-1/2 a bushel, on track for a fourth consecutive weekly decline, as traders weighed diplomatic efforts to restore Black Sea grain flows against ongoing port disruptions. Chicago grain futures slipped on Friday under pressure from those diplomacy headlines. A persistent paradox has defined the week: physical supply disruption out of the Black Sea is severe, yet futures have fallen on expectations that talks will eventually reopen export corridors — a bearish signal for CBOT wheat settlements into October.
Trump-Xi summit one week away drives the soybean trade
Soybean futures tumbled over 10 cents overnight as the market looked ahead to a key Trump-Xi meeting scheduled roughly one week out, with November soybeans quoted down 2¾¢ at $13.15¼ per bushel early Thursday. Chicago小麦-linked markets are treating the summit as the decisive event for whether China returns to US soybean purchases; wheat futures led a broad corrective pullback across the grain complex as traders marked time ahead of the summit. Any concrete Chinese commitment would be the single most bullish catalyst for CBOT soybean settlements and weekly USDA export sales.
Black Sea blockade is a "second Hormuz" for grain
Bloomberg analysis carried by Russian-language outlets described Black Sea shipping disruptions as comparable to a blockade of the Strait of Hormuz for the oil market, with wheat exports from Russia and Ukraine falling as much as twofold and world wheat prices up roughly 40% on strikes against Black Sea ports. Russian wheat, barley and corn shipments in September were reported sharply lower than a year ago, while buyers in Egypt and Turkey face rising food-price risks. Asian buyers are paying premiums of up to a quarter of the value for Australian wheat as a substitute. The disruption keeps a floor under export parity for US and EU wheat even as futures correct.
Argentine agroindustry projects record $42.2 billion in export FX
The Rosario Board of Trade (BCR) estimates Argentina's agro-industrial sector will export $42.2 billion this year — the largest annual FX contribution in history — even as the harvest is seen falling about 10% to 155.8 million tonnes from 172.4 million last campaign. The Buenos Aires grains exchange separately projected the 2026/27 season could reach 157.9 million tonnes. BCR is analyzing hedging strategies for soybean and corn as 2026/27 prices rise, and the BCR agro-activity index hit a record high in August, up 19% year on year. Strong South American supplies cap upside for CBOT soybean and corn spreads into the northern winter.
Brazil: slow soybean planting, strong domestic prices
Brazilian domestic soybean prices rose even as New York futures fell ahead of the Trump-Xi talks, with Globo Rural noting that planting of the 2026/27 crop remains slow. A weaker real and a stronger dollar favor export premiums at Brazilian ports, keeping Brazilian origin competitive against US beans during the US harvest window.

Local view
- Brazil (Globo Rural): reported soybeans rising almost 2% in Chicago on possible Chinese purchases of US grain, with corn and wheat also closing higher earlier in the week; corn futures faced pressure from a US harvest expected to top 400 million tonnes for a second straight year and from farmer stock cleanout ahead of the new crop.
- Russia (finance.mail.ru / Pravda.ru): Russian analysts flagged a historic pivot of Russian grain exports toward Baltic and Arctic ports as Black Sea routes are disrupted.
- Argentina (Infocampo/Cadena Láser): Rosario cash board quotes were published daily, with local coverage focused on rising 2026/27 soybean and corn prices and farmer hedging.
Context & numbers
- CBOT wheat: $6.92-1/2/bu, down 2.1%, fourth straight weekly loss.
- CBOT soybeans: lost 0.9% to $13.05-1/2/bu, though up 0.2% on the week.
- Nov soybeans $13.28 (up 24½¢) and Dec corn $5.43 (up 15½¢) closed Monday, Sept. 21, showing how sharply sentiment reversed through the week.
- World wheat prices up ~40% due to Black Sea port strikes, per Ukrainian media.
- Argentina export FX projection: $42.2 billion; harvest seen at 155.8 Mt (-10%).
- USDA AMS daily report for Sept. 23 showed CBOT settlements with mostly lower basis changes at Hallock, Enderlin and Velva canola/Grain markets.
On the radar
- Trump-Xi summit, expected within days — the pivotal event for Chinese US soybean buying and USDA export sales expectations.
- September Russian grain shipments: reports of 10–20 September wheat shipments falling several-fold vs. 2025 warrant monitoring of October loadings.
- Brazil 2026/27 planting pace: slow onset could shift export premiums toward the US later in the season.
- BCR hedging programs for 2026/27 soy and corn as prices rise — a rumor-level signal of farmer selling pressure ahead.
