Why are potato prices falling right now?

Potato prices fall the way they rise, only with the calendar's help: every fall a new crop is dug whether or not the market wants it, and that reset is the single most reliable downward force in this market.

The harvest reset comes first. When the fall crop comes in big and sound across Idaho and the Columbia Basin, the sheds fill, shippers compete for movement, and the benchmark typically sets its seasonal lows in the months after digging.

Storage economics keep the pressure on. A stored potato costs money every month it sits, and the crop must move before quality declines, so a big crop creates its own selling pressure all winter; the movement volumes on the origin pages are the public read on how hard supply is pushing.

A clean size profile keeps the whole ladder cheap. When the crop runs big and uniform, every count is plentiful, the carton-count spread compresses, and no size class can carry a premium worth chasing.

District overlap is the competitive counterweight. When many districts quote at once, the storage regions, the southern spring crops and Canadian imports together, buyers have alternatives and no single shipper can hold a price; the weekly board shows that breadth directly.

Contracted processing volume caps the upside of demand. Most fry and chip potatoes are locked at contract prices before the season, so in a well-supplied year the fresh market cannot lean on processors to absorb the surplus, and the open supply competes for the same fresh demand.

A falling stretch usually starts with a big, sound crop meeting steady demand, with storage economics and district overlap deciding how far it carries. The rising twin of this page covers the same factors running the other way.
