I guess you never heard of a Grain silo or fuel terminal.
All you need is a silo operator to rent storage which is cheap,
and frankly how commodity’s speculation works now.

People buy futures contracts and sell futures contracts
and close out the position before delivery.

If i buy Octobers corn crop, i’m usually planning a november sell date
anyways. or vice versa, my contract sells before it needs to be moved.

There have been a lot of tankers sitting offshore all year waiting for
oil to rise, so, that’s cheap storage too. Just pay the Baltic dry index rate.
