The furore over the US government's failure, thus far, to resolve the stalemate over the US debt ceiling wasn't the only tempest that agricultural commodity markets had to factor in on Monday.
There was a real storm too, in India, where Cyclone Phailin made landfall on Saturday with winds of some 125 miles per hour, killing a reported 18 people, and leaving a trail of crop destruction too.
'Exports likely to be affected'
But how much damage?
According to some reports, up to 1m tonnes of rice have been destroyed.
Luke Mathews at Commonwealth Bank of Australia said: "This represents less than 1% of India's total rice crop, although exports from the world's top shipper are likely to be affected."
India is forecast by the US Department of Agriculture to ship 9.3m tonnes of rice in 2013-14, with the International Grains Council forecasting a figure of 8.5m tonnes.
If storm losses were reflected directly in reduced exports, this would indeed mean quite a fall. But India also has substantial inventories to call upon.
Certainly, rice futures in Chicago failed to react too much, adding 0.3% to $15.160 per hundredweight for November delivery as of 09:10 UK time (03:10 Chicago time).
'Concerns of quality downgrades'
Another potential crop affected is sugar cane.
However, "despite the intensity of the storm", the worst to hit India's east coast in 14 years, "damage to sugar cane production is likely to be relatively small on a national basis because key producing regions appear to have been spared".
In fact, raw sugar futures, which rose on Friday in part on expectation of the storm, eased back 0.3% to 18.87 cents a pound in New York for March delivery.
Ideas of the Environmental Protection Agency reducing the mandated ethanol blend in the US hardly helped by prompting ideas of a lesser need for imports from Brazil, inferring more of the country's cane will get turned into sugar rather than the biofuel.
Cotton did better, adding 0.6% to 83.83 cents a pound in New York for December delivery, recovering from its biggest weekly loss since August last week.
"Heavy rains and some flooding throughout the cotton-growing regions of India have fuelled concerns of potential quality downgrades to the current crop," Rabobank warned.
'Risk of recession'
As for Washington, the weekend failed to bring a resolution of the debt impasse, prompting Christine Lagarde, the head of the International Monetary Fund, to warn of "massive disruption the world over" if the US ends up defaulting on its debt.
"We would be at risk of tipping, yet again, into recession," she said.
Data over the weekend showing Chinese exports falling 0.3% last month, compared with expectations of a 6% gain, hardly helped.
Shares opened weak in Europe, down by 0.3% in London and by 0.5% in Frankfurt, although they did manage headway in China itself, adding 0.4% in Shanghai.
From a commodity perspective, the Chinese trade data at least showed healthy imports, up 7.4%, beating forecasts of a 7% rise, and shrinking China's monthly trade surplus to "just" $15.2bn.
Not that imports of many agricultural commodities were huge.
Buy-ins of soybeans, at 4.7m tonnes, were down 26% month on month, although some decline had been expected, and the impact of the data was cushioned by the huge margins that processors are currently enjoying, their highest for at least three years, of more than 100 remninbi per tonne, supporting thoughts of import demand.
Margins fell to a negative 80 remninbi per tonne, and more, in June.
Furthermore, ideas of rain delays to the US harvest are supporting the oilseed, and corn too.
Showers, which delivered up to 1.5 inches of rain through much of the western Midwest over the weekend, "will push across the Corn Belt Monday and Tuesday", MDA said.
"Amounts through Friday should be 0.25-1.0 inches, locally up to 2.25 inches, with 75% coverage."
Joyce Liu at Phillip Futures said: "The forecasts of rainfall over the next few days could be a source of support for soybeans as rain would slow down harvesting."
And indeed, soybeans for November added 0.6% to $12.74 ¾ a bushel, enough for the contract to retake the 200-day moving average.
Elsewhere, in the oilseeds complex, palm oil was not so upbeat, easing 0.5% to 2,369 ringgit a tonne in Kuala Lumpur, not taking the Chinese import data so well.
China's imports of vegetable oils fell 22% to 570,000 tonnes last week, Saturday's customs data showed.
However, back in Chicago, corn for December made some headway too, adding 0.3% to $4.34 ½ a bushel, again helped by US harvest delays, which ease the pressure on markets from seasonally rising supplies.
For corn, prices are getting extra support (although not enough to prevent them standing near three-year lows) from a reluctance among farmers to sell at values which are so low by recent standards, if not by historical ones.
'An end to drilling'
As for wheat, the market leader of late, it posted gains too, helped by an end to the drier spell which has helped some recovery in former Soviet Union autumn seedings.
"The settled weather forecast has turned in to heavy rain over many regions - that'll put an end to any late-drilled wheat," Ukraine farm manager and blogger Mike Lee said.
This helped put the focus back on supply hiccups, even as GrainCorp came in with a far more upbeat viewed than Australian Crop Forecasters on the progress of the early Australian harvest.
While ACF, hiking its forecast for the harvest's volume, cautioned over disappointing protein in early cuts in Queensland, GrainCorp said that, in the centre of the state, "volumes are lower this year due to dry conditions", but "quality has been excellent".
South American dynamics
Still, elsewhere in the southern hemisphere, reports from Argentina on its wheat fortunes get no better, with reports of mill closures because of the lack of grain left over from the 2012 harvest, and of local prices for the grain approaching $600 a tonne (well over twice Chicago values).
"Meanwhile, the opinion that Brazil continues to shop for US hard red winter wheat remains intact as there is little evidence to say that they have shifted their near-term focus elsewhere," Brian Henry at Benson Quinn Commodities said.
"US hard red winter wheat values traded into Brazil can still be processed with significant profit margin," and values elsewhere have been rising too.
Sydney futures, for instance, having been at a discount to Chicago until April, are maintaining a healthy premium, of roughly $0.40 per bushel.
Chicago wheat for December stood up 0.5% at $6.95 ¾ a bushel, with Kansas City-traded hard red winter wheat up 0.4% at $7.63 ½ a bushel.
