CME hogs settled higher led by firmer cash and wholesale pork prices, said traders.
They said deferred hog contracts topped technical resistance levels, which triggered buy stops and fund buying.
February hogs , which expired at noon CST (1800 GMT), ended up 0.425 cent per pound to 75.175 cents. Most actively-traded April closed 1.600 cents higher at 71.300 cents, and above the 10-day moving average of 70.690 cents.
Tuesday morning's cash hog price in Iowa/Minnesota averaged $71.96 per cwt, up 37 cents from Monday, the USDA said.
U.S. government data on Tuesday morning showed the average wholesale pork price, or cutout, $1.45 per cwt higher at $86.59 from Monday, mostly led by $3.55 higher pork bellies.
Packer margins remain strong and they are still moving product in the face of record-high production, said Hehmeyer Trading + Investments senior hog futures trader Tom Cawthorne.
He expects strong pork belly prices for at least another week or so due to robust bacon demand.
