The first data salvo of the day went without too much bluster.
That is, Chinese agricultural commodity futures were little moved by the country's official monthly Casde crop supply and demand report, with Dalian
In fact, the Casde raised by 1.78m tonnes, to 212.48m tonnes, the forecast for China's corn harvest, and by 500,000 tonnes, to 1.5m tonnes, the forecast for imports of the grain too, with the result being a cut below 900,000 tonnes in the estimate for the stocks drawdown in 2017-18.
For soybeans, the most notable change was a 1.34m-tonne upgrade to 94.5m tonnes in the forecast for China's imports in 2017-18, while elsewhere, the estimate for
Still, Zhengzhou cotton futures for January eased by 0.4% to 15,620 yuan a tonne, easing alongside New York peers, and with Chinese state auctions seeing a slight reduction in sale rates (to 94.0% on Monday) now trading houses have been barred.
Still, further data tests await investors on Tuesday, with Conab poised to unveil monthly data on Brazil's grain and oilseed crops.

Investors expect small downgrades to both.
And ideas of an easing in soybean yield prospects gained some support from the release overnight by the USDA of data showing an easing of 1 point, to 60%, in the proportion of US soybeans rated "good" or "excellent".
(That said, Wasde estimates will be based in the main on already-completed surveys.)
"The market is looking for a small cut in yields to reflect unseasonable weather here and there in the US," said Tobin Gorey at Commonwealth Bank of Australia.

Still, Chicago soybean futures for November eased by 0.3% to $9.57 ½ a bushel for November delivery, with one more positive aspect for yields ideas that one knock-on effect of Hurricane Irma might be welcome rains to parts of the Midwest.
"The storm is expected to cause a shift in the overall weather pattern," said Benson Quinn Commodities.
"It appears this shift will offer better precipitation for much of the Corn Belt.
"Look for better precipitation in the Northern Plains and western Corn Belt in the 6-to-10 day forecast."
For corn, Mr Gorey's assessment was much the same that "US Midwest weather has not broadly been a problem but it has been well short of perfect in some parts.
"In those parts, yields are expected to fall.
"The crop outcome is not though going to be greatly different. Supply will remain comfortable," if perhaps slightly less comfortable than had been thought, if traders have called the Wasde changes right.
Chicago corn futures for December dipped by 0.6% to $3.55 ¼ a bushel in pre-Wasde positioning, but remain within their trading range this month, and between the narrowing funnel bounded by 10-day and 20-day moving averages which has pretty much confined them during this period.

And in Sydney, east coast wheat futures had a somewhat disappointing reaction to Abares' downgrade to its Australian crop forecast to 21.6m tonnes, in easing Aus$1.40 to Aus$265.60 a tonne.
"We suspect the market already has something lower in mind, perhaps even sub-20m tonnes," Mr Gorey said, although adding that "this crop is going to be harder than usual to guess".
It will be interesting to see any reaction later in Paris prices, after Egypt confirmed earlier on Tuesday that it was rejecting a cargo of French wheat on grounds of contamination with poppy seeds, which looks to have replaced ergot as Egypt's import niggle of choice.
"Exporters are closely monitoring the situation in Egypt," said Agritel, adding that "recent local regulatory demands will complicate the positioning of operators in next tenders" by Egypt's Gasc authority.
It may mean an increased premium too.
Meanwhile, the French farm ministry earlier raised by 1.0m tonnes to 37.8m tonnes its forecast for the domestic soft wheat harvest.
In New York,
"While Irma caused plenty of destruction and the many lives that have turned upside down can't be downplayed, the overall force of the storm and what it left in its wake was somewhat less than once anticipated," said Benson Quinn Commodities.
Traders at Ecom said that while there were "mixed views" on Irma, "what we can say is that the market usually knows first".
And based on price movements, "the market believes that Irma is no longer a major threat to cotton production".
Ecom added that Irma's winds are now down to about around 30mph, "and rainfall is only expected to be around 3.5 inches.
"Hurricane Harvey saw the Delta area get 5 inches of rain with no major damage as of yet" to cotton crops.
It does have to be said that USDA data overnight showed Irma arriving at a sensitive time, with 51% of Georgia bolls opening – a particularly vulnerable crop phase.
Still, also in bear's favour was an upbeat forecast from Abares on the domestic cotton harvest, seen at 2017-18 at its third biggest ever, despite the country's drought.
