The US Department of Agriculture has confirmed the ditching of the Wasde report, in the highest-profile casualty yet to agricultural markets of the US government shutdown.
The USDA confirmed that the Wasde, which had been set for Friday, would not be produced "due to the lapse in federal funding" after lawmakers failed a week ago to agree a US budget, a deadlock that triggered the temporary closure of non-emergency government operations.
No new date for the Wasde was set.
The announcement ditches the release of one of the world's highest-profile reports on agricultural commodities, giving supply and demand statistics worldwide on crops from cotton to corn, besides on US livestock and meat.
Indeed, it "leaves the market in a bit of a fog", said Societe Generale analyst Christopher Narayan, noting the difficulty investors face in obtaining accurate information.
Investors have begun "parsing together anecdotal field reports from around the US to gain a better perspective of US corn and soybean production estimates".
Other casualties of the shutdown have included the weekly reports, and daily alerts, on US crop exports, an omission highly sensitive to the wheat market in particular given the talk of strong demand for US wheat from the likes of Brazil and China.
The weekly Crop Progress report, on factors such as harvest pace and crop condition, due later today has also been shelved.
In livestock markets, the lack of information from the USDA has prompted CME Group to suspend its lean hog and feeder cattle indices, besides potentially provoking problems for settling the expiring October contracts.
These require USDA data, to ensure convergence of cash and futures prices.
One complication of the Wasde's delay is that there are legal restrictions on the date range within which it can be released, according to traders.
Broker US Commodities said that the report must be released within the 9th-13th of the month, with RJ O'Brien reporting the date range at 8th-14th.
This Wasde had been particularly eagerly anticipated given that it was expected to revise estimates for crop area for US corn and soybeans, besides for yield.
For soybeans, for which the USDA currently sees inventories recovering by a modest 25m bushels over 2013-14 to 150m bushels, the area figure is seen as particularly important.
