JBS reported that China has blocked U.S. beef shipments from its Colorado plant after detecting ractopamine. The restriction sent CME cattle futures lower on Wednesday, with the August live cattle contract posting its biggest percentage drop since May 1.
The Chinese ban removes a export destination for a major US beef packer, weighing on live cattle futures. The price effect depends on whether the restriction spreads to other plants.
After 121 past bearish trade events, Live Cattle moved a median -0.6% over 5 sessions (40% higher; middle half -1.6% to +0.8%), and -0.3% over 20.
