A generational gold allocation is not a trade. It is built once, adjusted rarely, and inherited by people who did not choose it. Everything that goes wrong with these structures goes wrong administratively — not because the price moved, but because nobody wrote down where the metal is and who is entitled to it. This edition is general educational material, not advice; the structures described require local legal and tax counsel.
Decision one: sizing
The conventional five per cent allocation comes from a specific set of assumptions — a stable monetary regime, positive real yields on sovereign debt, and bonds that diversify equities. When those assumptions hold, five per cent is defensible. The relevant question is not what the textbook number is but whether the assumptions behind it still describe the world you are allocating into.
The more useful framing replaces how much should I hold with what am I insuring against, and how much cover does that require. If the exposure you are hedging is a domestic currency and a domestic banking system, the position needs to be large enough to matter if that exposure fails, and it needs to sit outside that system. That reasoning produces a range rather than a number, and it produces a different number for a family whose operating business, property and pension are all denominated in one currency than for one already diversified across three.
Whatever number you arrive at, write down the reasoning next to it. In fifteen years someone will ask why the figure is what it is, and the answer must not be because that is what it has always been.
Decision two: form
Long-horizon allocations are typically dominated by allocated, audited physical metal, with a smaller liquid sleeve for rebalancing. The logic behind that split is functional rather than aesthetic: the physical share exists to be untouchable, and the liquid share exists to be touched.
This matters more than it sounds. A position you can sell in ninety seconds from your phone will eventually be sold in ninety seconds from your phone, usually during the exact week you should not. Deliberate friction — a vault, a custodian instruction, a settlement window — is a feature of the physical leg, not a cost of it. Meanwhile the liquid leg absorbs the rebalancing trades so the core is never disturbed.
The exchange-traded sleeve brings its own considerations: whether the fund is physically backed and allocated, whether it permits redemption in metal and at what size, its expense ratio compounded over decades, and its tax treatment in your jurisdiction, which for precious-metals vehicles is frequently unlike that of other funds.
Decision three: jurisdiction
Most families under-think this and diversify geographically when they should be diversifying legally. Two vaults in two countries under substantially similar legal systems, similar treaty networks and similar political alignment are one jurisdiction wearing two hats.
The questions that actually differentiate a storage jurisdiction: is the metal held in a bailment arrangement outside the custodian's estate in insolvency; does the country have a modern history of capital controls or requisition; what is the tax treatment on storage, transfer and inheritance; what physical access rights does an owner or heir have, and how are they exercised from abroad; and how deep is the local dealer market if a sale becomes necessary at short notice.
Concentration risk here is not only about the country. Multiple accounts with the same vault operator, or metal insured by the same underwriter, is a single point of failure regardless of where the buildings are.
Decision four: succession
This is where these structures actually fail. A vault holding with no documented succession is not an inheritance; it is a puzzle left to grieving people who do not know the vocabulary.
The minimum viable documentation: the holding entity or trust and its governing law; the custodian and account references; the auditor; who is authorised to instruct, and how that authority transfers on death or incapacity; the bar list with serials and assay certificates; the insurance policy and its limits; and the written rebalancing and disposal rules, so heirs are not left interpreting intent.
That package should live in at least two places, at least one outside the jurisdiction of the metal, and someone who is not the principal needs to know it exists. Review it whenever the family, the custodian or the law changes — which in practice means at least every couple of years.
The point of the exercise
None of this is exciting, and that is the whole argument for it. A well-built core is the part of a balance sheet that permits the rest to take risk, and the highest praise it can earn is that the next generation never has to think about it.
