Screwworm cases rose sharply in the United States this month, according to the Hightower Report. Feeder cattle led the cattle complex higher on Friday, and December live cattle rallied to a new weekly high after an early dip.
A rising screwworm caseload tightens cattle supply and movement, which supports feeder cattle prices and raises feed demand. It also increases the risk of trade restrictions on live cattle.
After 122 past bullish disease events, Feeder Cattle moved a median +0.4% over 5 sessions (60% higher; middle half -1.0% to +1.6%), and +2.0% over 20.
