Black Sea Tensions, Heat Waves in Europe, and ProFarmers US Crop Tour are the main grain market influences.
Grain and cotton markets extended their run into the new week, with US corn and cotton futures both touching fresh contract highs on Monday and Australian cash wheat sitting at or near season highs in most states. The catalyst remains the Pro Farmer's annual US Crop Tour, which pointed to a smaller than expected corn crop and a potentially record soybean crop, a split result that helps explain why corn and beans have moved in opposite directions this week. Sitting on top is a fragile Black Sea shipping situation and a fresh round of US and Canada trade tension, both reminders that price support right now is coming as much from disruption risk as from underlying supply and demand.
Grain and Oilseed Markets
Wheat remains the standout. CBOT wheat is trading around US$6.81 a bushel (USD $250.50/mt), its best level in about a month, while Australian cash wheat is trading at or near 12 month highs in South Australia, Southern New South Wales and Victoria. The support is coming from the Black Sea, where Ukraine's grain exports have slowed to a trickle, just 188,200 tonnes in the week to 19 August, well down on normal, because ports remain effectively blocked. President Zelenskiy says Russia is not yet willing to agree to a shipping ceasefire. In plain terms, every extra week that Black Sea grain struggles to reach the water adds a bit more support to wheat prices everywhere else, Australia included. The flip side is just as important, if a ceasefire or workaround is reached, that Black Sea grain could return to the market quickly, and prices could give back recent gains just as fast. CBA describes this as the largest logistical shock to Black Sea exports since the 2022 invasion, and is flagging the possibility of a short but sharp price spike if the disruption drags on.
India is adding a wrinkle to the wheat story too, lifting its multi year ban on wheat and flour exports after a record 120.6 million tonne harvest. On paper that is more wheat available to the world, which usually caps prices, but AgResource notes Indian wheat is still priced too high to compete in export markets for now, so do not expect an immediate impact.
Corn has been the biggest mover, CBOT corn punching through to fresh three year and contract highs this week, last near US$4.91 a bushel (USD $193.49/mt). The driver was Pro Farmer's Crop Tour, an annual, boots in the paddock survey of the US corn belt, which came in with a national yield estimate of 173.2 bushels an acre (10.87 tonnes a hectare) and a total crop of 15.344 billion bushels (389.8 million tonnes), smaller than many traders had pencilled in. A smaller than expected US corn crop, at a time when global demand keeps growing, is a genuinely bullish setup, and it shows up in the numbers, large speculative funds added more than 83,000 new long (bought) positions in the week to 18 August. The balancing risk is that this is still an estimate, not the final USDA number, so any upward revision in coming reports could take some heat out of the rally. Having said this, the declining corn yields in the US, are also supported by declining yields in the EU, with current forecasts ~7% lower than the 5 year average.
Soybeans tell the opposite story. The same Crop Tour pointed to a possible record US soybean crop, near 4.572 billion bushels (124.4 million tonnes) on a yield of 53.3 bushels an acre (3.58 tonnes a hectare), with scouts reporting above average pod counts in the paddock. A bumper crop is naturally a headwind for prices, and soybean oil slipped to a six week low as traders unwound positions, though strong crush demand, more soybeans being processed domestically in the US, is providing some underlying support and keeping the pullback orderly rather than sharp.
Canola and rapeseed have had a strong run since early July, up around 8% on ICE in Canada and around 6% on MATIF in Europe, riding the same Black Sea disruption story, since Russia and Ukraine between them account for roughly a fifth of global canola stocks. Over the past week both have eased a little on profit taking and softer soybean oil, Paris rapeseed futures down about €20 in the last week to €522 a tonne, but the underlying trend remains firm. Australian GM and non GM canola have followed the broader trend higher, up 0.5% and 3.6% respectively since early July.
Barley has lagged the rest of the grain complex, down around 2.2% since early July, though a Jordanian tender for 120,000 tonnes this week is a reminder that Middle Eastern demand can move quickly and add support when it shows up.
Delivered wheat and barley Darling Downs bids for September/October deliver (September slots are nearly full) are ~$410. The bid side of the market has been quiet on the back of last weeks, and this week’s rain forecasts. New crop Sorghum delivered Narrabri ~$350 with not all buyers active in the market as they await the meeting between Chinese and US President in September. Another factor feeding into sorghum uncertainty is supply from South America into China.
Cotton
ICE cotton has now rallied for five straight weeks and pushed through to a fresh contract high close of 89.45 US cents a pound (USD $444.15/bale) last week, and currently ~88.26 today. The fundamental support is real, US crop conditions have deteriorated for a third straight week, with drought gripping Oklahoma, Kansas and Texas. But positioning in the futures market has become extreme, Commitment of Traders data shows trade related buyers holding a record large net long position of around 13.1 million bales, with speculative funds also heavily long. When that many players are leaning the same way, the market can be vulnerable to a sharp correction if the weather turns more favourable or if any of those large positions start to unwind, so this is a market where the trend is your friend until it very suddenly is not.
Currency, the Aussie Dollar
The Australian dollar eased through Monday's session, slipping from around 71.71 US cents to the 71.40 to 71.50 US cent range, as broader US dollar strength and a soft tone in global equity markets weighed on the currency.
The Global Backdrop
Beyond the paddock, there is a genuinely large amount of geopolitical noise feeding into markets right now. The US and Canada have reignited a trade dispute, with new US tariffs on Canadian goods and Canadian retaliation flagged from 8 September, though corn, soybeans, ethanol, beef and pork have been excluded from the list so far, the key detail for our clients. Separately, the US is reportedly preparing a broad sanctions package against Iran and countries that trade with it, which has helped keep oil prices elevated, Brent testing above US$95 a barrel, with only an estimated 20 to 50% of normal shipping volumes able to move through the Strait of Hormuz. Higher oil prices flow through to freight, fertiliser and on farm fuel costs, and we believe this will help hold our commodity prices higher, although in real terms, you are no better off.
Weather
At home, WA and SA cropping regions picked up a useful 5 to 25mm of rain last week, with Victoria and southern NSW getting a more solid 10 to 50mm. That is welcome follow up moisture, but the Bureau of Meteorology's outlook for the September to November period still points to an elevated risk of a dry spring across the south eastern cropping belt and the far south west of WA, worth factoring into decisions around spring finishing and marketing timing. Overseas, Europe's crop monitoring service has cut its yield outlook for summer crops, corn especially, across western and central Europe on persistent heat and drought, most notably in Hungary, while parts of the US Southern Plains remain under extreme heat even as Midwest showers ease some of the immediate stress there.
What This Could Mean for You
For wheat and barley growers, the current price strength is being driven by a supply disruption rather than a change in the underlying demand and supply balance, which is exactly the kind of rally that can unwind quickly if circumstances change. It may be worth considering locking in some forward sales into this strength rather than waiting for the very top of the market, particularly given cash values in South Australia, Southern New South Wales and Victoria are all sitting at or near season highs.
For canola growers, values remain well supported by the same Black Sea story, but with harvest pressure building in the Northern Hemisphere and a small pullback already underway, this is a good window to review your marketing plan and make sure you are comfortable with your position heading into spring.
For cotton growers, the extreme positioning in the futures market cuts both ways, prices are strong, but the setup is stretched, so this is a market to watch closely rather than assume the trend continues in a straight line.
Managing Your Risk
As always, the best marketing strategy is built around managing risk, not predicting outcomes. Reward rallies with incremental sales, continue updating your production estimates and stock levels as the season unfolds, and remember that buyers can't buy what they can't see. If there are opportunities to show grain or cotton to multiple buyers, competition remains one of the best ways to improve your average price.
