What moves potato prices

Potato prices move on supply, because demand barely moves. People eat about the same volume of potatoes week to week, so the demand side is close to a constant and the supply side does nearly all the work. Every real price story on this market comes from supply, and it stacks up in a predictable order.

The supply stack

Start with acreage. How many acres growers planted, decided months before harvest, sets the ceiling on the crop. Then the growing-season weather at each origin: a hot dry stretch, a wet dig or an early freeze can pull tonnage off that ceiling. Then storage, which runs the back half of the year: a stored crop shrinks and can degrade, so how well the potatoes hold and how much sound US No. 1 stock is left drives the winter and spring. The Columbia Basin chart above is one origin's FOB carrying those forces. Because each region grows and stores on its own conditions, one origin can firm while another eases, which is why potato prices are really a set of regional stories rather than one national number.

Freight, exports and the handoffs

Three more levers sit on top of the crop. Freight is the wildcard on the delivered price: the potatoes can be flat at the shed while the landed cost jumps because trucks got tight or fuel moved, and this site reports the FOB, not the freight. Export pull is another, when demand across the border draws supply out of a region. And the handoffs between growing regions are the classic volatility windows, when one origin is selling down its cellars and the next has barely started, so supply is thinnest and a price can jump before the new crop settles it.

Worked example: the biggest mover

Take the biggest move on the board above and run it through the stack. First ask which origin it is and where that origin sits in its season, because a move on a region selling out reads differently from one just getting going. Then ask whether it is a handoff week, one region passing the market to another. Then whether the shipment volumes are confirming it. Most big potato moves resolve into one of those supply stories: a short crop, a quality problem, a thin handoff or a freight jump. Demand is rarely the answer.
