CHICAGO, Jan 3 (Reuters) - U.S. hog futures tumbled by the daily trading limit to a three-week low on Friday as rising geopolitical tensions in the Middle East triggered profit-taking, analysts said.
Losses hit markets after a U.S. air strike in Iraq killed Iran's most prominent military commander, rattling traders of products from agricultural futures to equities.
The strike temporarily overshadowed expectations for increased Chinese buying of U.S. pork. China, the world's largest pork consumer, committed to buying more U.S. farm good as part of a Phase 1 trade deal the countries struck last month. The deal has not yet been signed, though, and details have not been announced.
Traders are paying close attention to Chinese purchases because China is facing a meat shortage caused by a fatal pig disease that has decimated its herd. The disease, African swine fever, has also infected hogs in other parts of Asia and Europe, including Bulgaria.
China bought 9,741 tonnes of U.S. pork for delivery in 2020 from Dec. 20 to 26 and also canceled purchases of 13,258 tonnes for delivery in 2019, the USDA said in a weekly report. Shipments over the same period were 10,404 tonnes, the lowest since late October.
"The hog market anymore is, 'Let's see what weekly export sales and shipments are,"' a commodities broker said. "For a holiday week, they were respectable."
Most actively traded February lean hog futures dropped the daily 3-cent limit to 68.550 cents per pound at the Chicago Mercantile Exchange (CME). The contract reached its lowest price since Dec. 12, a day after touching a seven-week high. The CME on Monday will temporarily expand the market's daily limit to 4.5 cents.
Selling also hit beef markets, with most actively traded February live cattle futures falling 1.050 cents to 124.725 cents per pound at the CME. March feeder cattle futures slid 1.050 cents to 142.675 cents per pound.
U.S. supplies of the livestock are ample. Meat packers slaughtered an estimated 122,000 cattle, up from 119,000 head a year earlier, and 493,000 hogs, up from 478,000 a year ago, according to the USDA.
In the cash market for pork, prices increased for carcasses and hams, but weakened for loins, butts and ribs, the USDA said.
