Agricultural commodities found some gaps in the clouds which have hung over raw materials markets, as fundamental considerations came back more into play.
The sell-off continued for many commodities, such as
"Holy cow. Silver fell off the cliff lately," was how Mike Mawdsley at Market 1 put it.
And some agricultural commodities leached further support too, as investors took a gloomy view of the impact of tighter global monetary policy, following the super-relaxed stance imposed during the world recession.
The fear is that the end of ultra-easy money will slow demand for raw materials both from trade and fund buyers.
The fall followed a dismal performance by cotton futures on the Zhengzhou exchange in China, the top consumer and importer of the fibre, which is showing further signs of demand destruction following the record prices hit earlier in the year, with mills reported to be shutting for a week for the May Day holidays.
Zhengzhou cotton for September plunged 5.9% to 24,640 yuan a tonne.
But the big Chicago crops put in the more solid performance which believers in the "oats knows" thesis would have forecast from last night, when the grain, seen as something of a front-runner for peers, managed a positive close.
"Although yields may beat expectations, they'll still be poor," Luke Mathews at Commonwealth Bank of Australia said
And then there are the wet conditions slowing Canadian and US spring sowings, and the dryness in China and Europe, to factor in too.
"Dry conditions are still observed in France, Germany, Poland and on the north of Europe in general, with potential yields decreasing slightly each day," Paris-based Agritel said.
Ker Chung Yang at Phillip Futures said: "Weather remains an issue and bears continued watching in several of the key US and international growing areas,"
[Soft red winter] wheat for July recovered 0.7% to $7.77 a bushel in Chicago, with Kansas hard red winter wheat for July adding 0.4% to $8.81 a bushel.
Such thoughts are being encouraged by the release next week of the US Department of Agriculture's first estimates for major grain and oilseed crops worldwide in its latest Wasde report on world supply and demand in agricultural commodities.
Corn itself has also been helped by reports of China ordering the delivery of some corn, apparently, bought from the US earlier in the year, meaning the trade will not go the way of some recent cancelled
Soybeans added 0.6% to $13.59 ½ a bushel for July, after winning some support from technical factors in bouncing off an "uptrend line" in the last session.
Resistance to more gains looks like being met at about $13.70 a bushel, where 20-day and 50-day moving average lines are grouped, while "closing below $13.30-13.35 would look bearish at this point" Mr Mawdsley said.
Will the rally hold? The signal from oats was undecided, with Chicago's July lot unchanged at $3.46 a bushel.
A better idea may be gained from weekly US export sales data, expected to show corn sales in line with last week's 444,000 tonnes, soybeans' in line with their 199,000 tonnes last time, and wheat potentially falling short of its 418,000 tonnes a week ago.
More reports will also emerge from the tour of Kansas hard red winter wheat crops, with Canada releasing a quarterly stocks report.
