The farm commodities week started with two ags in particular in demand – raw sugar and wheat.
Only one of them kept up its resilience to the end.
And it wasn't raw sugar, which tumbled the most for nearly a year, on spot contract terms, ending down 3.7% at 16.87 cents a pound in New York for October delivery.
The better-traded March lot dropped 2.5% to 17.74 cents a pound.
The plunge came amid concerns of what higher prices may have done in encouraging a hefty delivery against the October contract, which expires on Monday.
"A large delivery may dissuade the bulls from adding to longs as homes may be needed for the sugar," Nick Penney, senior trader at Sucden Financial, said.
"With increased trade participation in deliveries and hot competition among the sales teams at destination, coupled with a long delivery period, it may not be until the end of the year that the market finds out if the sugar has been sold or washed out."
Ideas of a large delivery have stoked by a relatively large amount of October contracts left live, at 60,000 as of close of play on Wednesday.
'Little evidence of demand increasing'
The cash market, whose resilience was one factor highlighted by Czarnikow earlier this month in its market-moving report that demand had been higher than thought, is sending negative signals too.
Mr Penney said: "Physical values for prompt shipment in South Brazil, at Paranagua, are reported at an 8-point discount to the expiring October futures contract, so there is little evidence of demand increasing in the foreseeable future unless weather patterns were to change," and dampness hampers the cane harvest and choke off sugar supplies.
Investors also got a reminder of strong production, with a forecast from Thailand, the second-ranked exporting country, of output of 11m tonnes, higher than the International Sugar Organization estimate (if below that of Kingsman).
"It is uncertain how much higher prices will be afforded to run given very strong production prospects in India and Thailand," Luke Mathews at Commonwealth Bank of Australia said, somewhat prophetically, earlier.
Furthermore, Job Economia sounded a negative note when flagging the prospect for Brazil, the top sugar producing country, to import ethanol from the US.
"Based on the price levels we are seeing in the ethanol futures market in the US, there may be opportunities for importing ethanol to Brazil's Centre-South region during the mid-crop period," the Brazil-based consultancy said.
"Last week the price of ethanol in the US was around $480 per cubic metre, in São Paulo it was $580 per cubic metre, while in the North-North East it reached $ 700 per cubic metre."
More imports would act in reducing prices of domestic ethanol, which would in turn likely act to divert more cane to sugar production and weigh on values of the sweetener too.
'Premium too wide'
On the grain markets, wheat certainly had its detractors.
"We feel the premium of over $2.00 a bushel in the spread between July Chicago wheat and July corn is too wide and will eventually narrow when the euphoria over wheat fades," Darrell Holaday at Kansas-based Country Futures said.
However, investors proved unwilling, as yet, to stem their enthusiasm for the grain, especially with ideas that a key US Department of Agriculture crop stocks report on Monday may prove bullish, in giving a low inventory figure.
"The previously reported large fund short position in wheat futures has also been a factor of support," Paul Georgy at broker Allendale noted.
'Wheat has taken the lead'
The story remained of strong demand for US supplies, stoked by waning expectations for the Argentine crop, at a time when Brazilian and Chinese demand is proving strong.
"Wheat has taken the lead in Chicago as weather problems in China and Brazil has degraded the quality of harvestable crop," Mr Georgy said, with Brazil said to be looked as far as Poland for supplies.
Benson Quinn Commodities said: "Strong export demand from Brazil, for hard red winter wheat, and China, for soft red winter wheat, and fear of larger wheat feeding in the [June to August] quarter could tighten the US balance sheet to point where price will have to ration demand for the winter wheats and price spring into the domestic and export markets."
As it was, the US announced on Friday the export sale of 121,600 tonnes of wheat to an "unknown" destination.
As an extra supply worry, Ukraine winter wheat sowings were said by industry officials to be running so far behind expectations that they could end up at 2.5m hectares, less than half of the government target of 7m hectares.
The country has been inundated with rain (depending on what reports you read) which has slowed fieldwork.
Wheat for December added 0.7% to $6.83 a bushel in Chicago – closing above its 100-day moving average for the first time in 2013, a factor which could bode well, technically, for prices next week.
It was also a three-month high for a spot contract.
Kansas City hard red winter wheat did the same in adding 0.6% to $7.31 ¾ a bushel for December delivery, while Minneapolis hard red spring wheat at least popped over its 50-day moving for the first time since June in gaining 1.0% to $7.31 ½ a bushel.
'Busy with fieldwork'
In Europe, Paris wheat for November added 1.2% to E193.50 a tonne for November delivery, nearly touching its 100-day moving average for the first time this year.
London wheat for November edged a modest 0.2% higher to £156.25 a tonne.
Still during the week, "as farmers are busy with fieldwork for the 2014 harvest, spot prices have increased sharply as merchants look to cover domestic sales", UK grain merchant Gleadell said.
Co-operative Openfield said: "The question for the UK now is how long before the ethanol plants start serious production and what feedstock do they use?"
Corn, after all, is cheap to import from the Black Sea, at about £140 a tonne ciffo.
'Ideal conditions for harvest'
Cheap Ukrainian corn has been one factor weighing on corn prices.
But another has been the spread of the US harvest, which looks set to continue at pace, given the weather outlook.
"Many areas expect harvest to close to full steam next week with weather conditions showing ideal conditions for harvest," CHS Hedging said.
And yield talk from the harvest is encouraging for growers too.
"Harvest yields remain impressive on corn with harvest expanding, US Commodities said, adding that "the fear for the bulls is that corn yields could push to 158-160 bushels per acre," from the current official estimate of 155.3 bushels per acre.
Furthermore, there is some worry that the US will curtail its ethanol production needs.
"The US House Energy and Commerce Committee are now meeting with renewable fuels producers," one broker noted.
"The headline hints that they are discussing the possibility of freezing ethanol production at current levels for a few years while adding more incentives for other low carbon alternatives."
December corn closed down 0.65 at $4.54 a bushel in Chicago, a discount of a hefty $2.29 a bushel to wheat.
'Weather appears to be improving'
Corn underperformed soybeans too, which added 0.3% to $13.19 ¾ a bushel for the November contract.
The oilseed had some headwinds to overcome, including largely better-than-expected US harvest results, which have sparked some ideas that the USDA may be forced to upgrade its yield estimate here too.
Furthermore, "the South America weather also appears to be improving," as US Commodities said, noting that "temperatures will be warming with better rain events across Argentina and much of Brazil starting next week".
However, demand ideas on soybeans remain decent too, after strong US export sales data, and Bunge revealed that it likely reopened its Emporia crush plant in Kansas, which has been idle since April, once harvest supplies ramp up.
'Expectations of abundant supplies'
Back among softs, robusta coffee set a fresh three-year low, dropping 3.1% to $1,611 a tonne in London for November delivery, depressed by ideas of a strong harvest ahead in Vietnam, the top producer of the variety.
"Robusta prices were also weighed ahead of the large crop from Vietnam, top grower of robusta coffee," Joyce Liu at Phillip Futures said.
"The lack of motivation to buy because of expectations of abundant supplies could continue weighing on robusta coffee prices."
And that was little help to arabica coffee, which ended down 1.7% at 113.70 cents a pound for December delivery, although at least restoring some of its premium to its competitor bean.
