Oil is down because of increased production and availability. Corn is down because of over supply.
We do not have an over supply of cattle. Even with people jumping into the cattle business, it still takes heifers 3 years to cash a check.
I have said all along that the consumer determined the demand. Retail beef quit moving as well. Some say due to pricing, some believe collusion.
The USDA said the recovery was almost complete. After the price crash they said, "Maybe not".
Prices were going to fall. There is no reason for the crash. No Mad Cow, no Pink Slime, nothing major.
Australian imports were up 50% in 2015. 70% of that was ground beef. It took lawyers to force the USDA to honor American company contracts for ground beef.
Did packers adjust weekly slaughter numbers to keep from buying form feed lots while they slaughtered their own Fats?
Did packers trade with packers to keep from buying from feed lots?
Did retailers push chicken and pork so cattle numbers would back up?
Who knows? I am just glad people with some authority are asking.
