A freeport is a bonded warehouse with climate control and a vault door. Goods stored there sit outside the local tax and duty regime until they are released, which makes them useful for anything valuable, portable and held for a long time.

Why the art market uses them

For a cross border collection the appeal is practical. Duty and tax are deferred, conditions are controlled, security is serious, and works can change hands without physically moving. That last point is the one with consequences: a painting can be bought and sold repeatedly inside the same building.

Scrutiny has tightened. Anti money laundering rules now reach the art trade in most major markets, and the direction of travel is towards more disclosure of who owns what, not less. The storage is still useful. The opacity around it is being withdrawn.

What it means for an allocator

A work that has sat in bond for a decade has a condition history that nobody has looked at in daylight and a market history that may be thinner than the paperwork suggests. Ask when it was last exhibited, last conditioned and last seen by someone independent. For a collection held as a store of value, bond storage is sensible. For one meant to be lived with, it is a sign the collection has stopped being a collection and become inventory.
