The job Insurance
Pays no income and does nothing useful, right up until currencies or governments are in question. Held for the days everything else falls together.
The argument
Gold pays nothing, produces nothing and costs money to store. It is held for the specific days when currencies or governments are the thing in question and everything else falls together — and it cannot be bought cheaply on those days, only before them.
The argument against buying eagerly right now is arithmetic: at 2.63% real, safe US government debt pays a genuine return after inflation, and every percentage point of that is a percentage point gold has to make up in price just to draw level. That is the discipline this reading imposes — it rewards patience over urgency, and it does not argue for selling.
The arguments for holding are the ones no interest rate touches. Central banks are absorbing 26.2% of new mine supply, buying for reserve-composition reasons rather than price reasons. And China refines 66.2% of eight critical minerals on average — a concentration that no market prices daily and that no portfolio can diversify away with more shares.
For someone in Thailand there is a practical fork. Baht-denominated gold on the SET at 136,214 baht per ounce removes the currency bet; the London-vaulted Irish ETC at 0.12% is by far the cheapest to hold; and physical metal from a gold shop is the only version with no counterparty at all, at the cost of a buy-sell spread and a place to put it.
