Pork has two headline prices that move for different reasons, and the gap between them is one of the most useful reads in the market. The lean hog price is the animal: what packers pay for market hogs. The pork cutout is the product: what the meat from a hog carcass sells for at wholesale, published daily by USDA on the afternoon pork report. Hogs are the packer's cost, the cutout is the packer's revenue, and the spread between them is the packing margin that decides how hard plants run.
The hog side: a cash-settled contract
The CME lean hog contract covers 40,000 pounds of hog carcasses, and unlike live cattle it settles in cash, not physical delivery. At expiration each contract settles to the CME Lean Hog Index, a two-day weighted average of actual hog prices reported to USDA under mandatory price reporting. That design changes how the board behaves versus cattle: there is no delivery arbitrage story to argue about, because convergence is mechanical. The futures price simply becomes the cash index at expiry. Away from expiry, a deferred lean hog contract is a pure forecast of where cash hogs will be on that date, and the market re-votes on it all day.
The practical consequence: when summer hog futures rally in spring, nothing about today's pork got more expensive. The board repriced an expectation. Cash hogs and the cutout are the only places today's reality prints.
The product side: the cutout
The pork carcass cutout values the meat itself: USDA prices the day's negotiated trade in loins, butts, picnics, ribs, hams, and bellies, weights them by their share of a standard carcass, and publishes one number in dollars per hundredweight. It moves on meat demand: retail features, bacon programs, export orders for hams, foodservice pulls. The belly deserves special mention because it is the cutout's volatility engine; a violent belly week can move the whole cutout while the other five primals sleep.
Reading the two together
The gap between hog cost and cutout revenue is the margin signal. A cutout rallying while cash hogs lag means packer margins are fattening, which historically keeps kill schedules full and pork supply flowing. Hogs rallying while the cutout stalls squeezes margin, and squeezed packers eventually cut kills, which tightens pork supply weeks later. When the futures board disagrees with both, remember which clock each price runs on: the cutout is today, cash hogs are this week, and the board is a bet on a date months out. A buyer of pork prices product against the cutout and its primal detail, uses the hog side to judge how sustainable current meat prices are, and treats the board as the market's published opinion rather than a price anyone pays for a ham.
On this site the pork carcass benchmark sits in the top strip on every page in native dollars per hundredweight, the full primal and item detail from the daily pork report lives on the cut prices pages, and the packing-margin read is tracked daily on the home tape. The two-price gap this article describes is watchable there in real time.
