Wednesday did not start too promisingly for many markets.
Shares tumbled 2.0% in Tokyo, and by 1.3% in Shanghai and Hong Kong, on concerns over higher borrowing costs in China, as borrowing rates for interbank loans rose.
Shares in banks and property groups were particularly hit in Shanghai as China's seven-day repurchase rate, a benchmark measure of funding availability within the banking system, rose as much as 0.42 percentage points, hitting 4%.
Brent crude fell 0.4% further below $110 a barrel.
But, as seems so often the case since the days of "risk on, risk off" trading disappeared, grains headed in the opposite direction, boosted by further concerns over supplies of wheat, which strengthened its foothold above $7 a bushel in Chicago.
If fears of Russian growers shutting off sales in hope of higher prices are growing, as noted in the last session, supply concerns are also reviving in Australia.
The Australian heat which has, through New South Wales wildfires which have destroyed more than 200 homes made global headlines, is set to hand around.
Australia's official weather bureau forecast warmer-than-average temperatures, and drier-than-normal conditions, across much of the country into January.
"It was forecasted that hot and dry conditions would persist for the next three months and this would adversely affect Australia's production of wheat," Joyce Liu at broker Phillip Futures said.
While helpful for harvesting, which has begun in areas such as Queensland, for less developed crops further dry weather represents a further setback.
Commonwealth Bank of Australia, noting that already "moisture stress", as well as frost damage, "is evident across much of New South Wales", cut its forecast for the national wheat crop by 1.6m tonnes to 23.6m tonnes.
This following some improved ideas of the harvest from other commentators earlier this month.
In Sydney itself, January futures for east coast wheat rose 1.5% to Aus$279.00 a tonne.
Meanwhile, demand ideas remain strong too, with tender activity continuing.
On Wednesday, South Korean flour millers bought 25,500 tonnes of Canadian milling wheat at about $300 a tonne from CHS, for February delivery, and just under 55,000 tonnes of US milling wheat for an unknown price, from CGI.
This follows the purchase on Tuesday by Jordan of 100,000 tonnes of milling wheat, optional original, for $304.50 a tonne, c&f, from Daewoo, while an Iraqi tender is ongoing.
And there is talk of Argentina, also the focus of crop concerns, buying too, to fill a void left by a disappointing harvest last year, and before the next (potentially disappointing) harvest begins.
Argentine import talk
"The trade now talking up the possibility of wheat imports hitting Argentinean shores in a bid to bring down local prices," Luke Mathews at Commonwealth Bank of Australia said.
CHS Hedging said: "Potential Argentine supply issues have led to increasing domestic prices right at election time. Will more imports be needed?"
Not that all commentators were so impressed, with Brian Henry at Benson Quinn Commodities flagging that talk was of two cargoes, totalling some 100,000-120,000 tonnes, a volume which "wouldn't typically grab headlines".
Still, with the technical help too from closing back above $7 a bushel in the last session, Chicago wheat for December added 0.7% to $7.05 ½ bushel as of 19:45 UK time (03:45 Chicago time).
'Rumours of strong sales'
That helped corn rise too, given that it is already trading at a hefty discount of more than $2.60 a bushel to wheat, a level which investors have been reluctant to exceed.
Furthermore, while US harvest yields continue strong, the uncertainty over exactly how much US corn was exported during the three-week US government shutdown continues to stem traders' willingness to sell.
This Thursday will see the USDA release US export sales data for the week to October 3, with the full catch-up not occurring until October 31.
"The bulls continue to discuss the rumours of strong corn and soybean sales to China over the last few weeks," one US broker said, if remaining bearish itself on the data.
"I think the market is figuring out that even if the US sold 3m tonnes of corn to China, it really won't make a significant dent in our final carryout."
Still, corn for December was 0.8% higher at $4.41 ¾ a bushel in early deals, recovering some of the ground in the last session.
That was more than soybeans could manage.
But then the oilseed posted only nominal losses in the last session, with US yields not looking quite as outstanding as for corn, and with concerns over South American sowings, particularly in Argentina, too.
Brazilian seeding are not so far behind, with 19% completed as of Friday, only 1 point behind last year, according to AgRural.
Still, Chicago soybeans for November added 0.1% to $13.04 a bushel, getting technical support too from the contract's ability to stay above the $13-a-bushel mark.
Among soft commodities, raw sugar returned to the back foot, as some investors took profits on its rally over the past couple of months.
"Traders continue to debate given future direction given prices on Friday lifted 20% from their August lows," CBA's Luke Mathews said.
While Czarnikow on Tuesday cast doubt on how long prices can stay below costs of production pegged at 22-23 cents a pound in Brazil and Thailand, the top exporting countries, others flag the need to work through the current world surplus.
"Price support might not be able to sustain as the International Sugar Organization stated the continuation of a global sugar surplus for the fourth consecutive year," Phillip Futures' Joyce Liu said.
New York raw sugar for March lost 0.7% to 19.31 cents a pound.
