What Is the Theoretical Maximum Difference between the Spot and Futures Price?

In a contango market, the theoretical maximum difference (premium) is the full cost of carry (financing, storage, insurance) until expiration. In a backwardation market, there is no theoretical maximum limit on how far the futures price can fall below the spot price, though extreme backwardation is rare and short-lived.
