New year, same old weather concerns.
The problem of South America's polarised weather, delivering too much rain in central Brazil, and too little further south into Paraguay and Argentina – with heat too – did not appear in any way resolved as of Tuesday.
Indeed, the weekend saw temperatures of up to 40 degrees Celsius (104 Fahrenheit) in central Argentina, posing a threat particularly to pollinating corn, although some other parts, and Paraguay, were a little cooler.
Rainfall was hardly abundant, where it is needed, either. (There was plenty in Brazilian states such as Mato Grosso and Minas Gerais where moisture has been plentiful.)
The extremes are being blamed on the La Nina weather pattern.
Rio Grande do Sol, a southern Brazilian state where dryness is the issue, saw "scattered light rain showers" on Sunday and Monday "which for the most part were under half an inch", weather service WxRisk.com said.
Some parts of Paraguay saw a little rain too.
But Argentina was dry throughout the weekend.
"The late Monday afternoon satellite picture shows that once again all of central eastern and northern Argentina as well as all Paraguay, south eastern and south west Brazil to be completely clear of any sort of clouds and any sort of thunderstorm activity," WxRisk.com said.
Nor does the outlook appear much more promising.
"The weather models did not show any significant change with regard to the rainfall and heat over Argentina, Paraguay and portions of south east Brazil over the next several days."
There is some chance of a cooler front this weekend. But next week, one weather model "tries to develop another heat dome", which would move from the southern Pacific into Argentina.
As for the impact on crops, Abiove, the Brazilian oilseeds industry group remained upbeat, with a forecast for Brazil's soybean crop, which in some areas is in the early stages of harvest, of 74.6m tonnes.
However, that forecast acknowledged no allowance for the poor weather of late,
Anecdotally, reports are coming in of water being trucked to some southern parts of Brazil for humans and livestock, such is the extent of drought, and corn chopped for silage, and in Argentina of poorly-developed corn being resown with soybeans, which can be later seeded.
All this has impacts for crop prices, of course.
"Traders are focusing on Argentina's corn crop as it is approaching its key development period of pollination," Lynette Tan at Singapore-based Phillip Futures said.
"Persistent dryness and rising temperatures in Argentina threaten the next harvest. That could shift demand to the US, the world's leading corn exporter."
Many US financial markets remained closed early on Tuesday, so any reaction was not seen in Chicago, (which will reopen with the live session later).
But in Kuala Lumpur,
Palm oil was helped too by concerns for weather in Malaysia too, which is also suffering La Nina-inspired problems, this time of too much rain.
"Fears of heavy rains in Malaysia's top palm oil producing states of Johor and Sabah that could trigger both harvesting and shipment delays are offsetting expectations of a likely weak demand outlook for the vegetable oil," Ker Chung Yang, at Phillip Futures, said.
Also a help was a more upbeat macroeconomic picture, with beginning-of-the-month purchasing managers' index readings for December from Australia, China and India showing improvement.
Australian manufacturing output grew for the first time in six months, while China's (according to an official figure complied by the China Federation of Logistics and Purchasing on behalf of the National Bureau of Statistics – not the HSBC one released last week) edged 1.3 points higher to a reading of 50.3.
Readings above 50.0 indicate expansion, and below, contraction.
