Should You Store or Sell Your Grain? A Basis + Carry Decision Guide

Every harvest ends with the same question: dump it at the elevator now, or put it in the bin and sell later? Too many farmers answer on gut feel — 'prices always go up after harvest' — and end up paying to store grain the market never paid them to hold. Storing is an active marketing decision with a real cost. Here's the framework to make it on numbers, not hope.

The three things that decide it

Whether storage pays comes down to three moving parts. Get these on the table before a single bushel goes in the bin:

• •Local basis — your cash bid minus the futures board. A weak (very negative) harvest basis that's likely to strengthen is the single best reason to store.
• •Futures carry — the premium deferred contracts trade over the nearby. When the market carries, it's literally paying you to store; when it's inverted, it's paying you to sell now.
• •Total carrying cost — storage/handling, interest on the value tied up, plus shrink and quality risk. This is the hurdle your expected gain has to clear.

Step 1 — Add up your real cost to carry

Don't assume storage is cheap. A working number for commercial storage runs about $0.025–$0.035 per bushel per month, and on-farm storage still costs you interest, shrink and quality risk even if the bin is paid for. Use a simple per-bushel formula:

Step 2 — Read your basis against history

Basis is where most of the opportunity hides. Pull your local elevator's current cash bid, subtract the nearby futures price, and compare that basis to its own 3–5 year average for this time of year. If harvest basis is much weaker than normal, it usually has room to strengthen into winter and spring — a real reason to store (or to lock the futures with a basis contract while you wait for the basis to improve).

Step 3 — Check whether the market is carrying

Look at the spread between the nearby and a deferred futures contract. A normal 'carry' market pays a premium for later delivery — you capture it by storing and selling the carry with a forward or hedge. An inverted market (nearby higher than deferred) is the market shouting sell now; storing into an inversion is fighting the tape.

The market pays you to store in a carry and pays you to sell in an inversion. Your job is to listen to which one it's doing — and know your cost to carry cold.

Step 4 — Sell, store or hedge

1. Sell now — if the forward move plus expected basis gain won't clear your carrying cost, or the market is inverted, or your operating note needs the cash. Move it off the combine.
2. Store (and sell the carry) — if the market carries and expected basis improvement more than covers your cost, store the grain but lock the price with a forward or futures hedge so you keep the carry, not the risk.
3. Hedge — if the price is historically strong but the forward is flat, lock today's level with a hedge instead of betting on more upside; store the physical grain against a strong basis.

Step 5 — Never store without a cash-flow plan

The most expensive stored grain is the kind you're forced to dump in a spring cash crunch. Before you fill a bin, confirm your operating note and spring expenses are covered by cash, credit or priced sales — so you sell on your timeline, not the bank's.
