Securities are värdepapper, says the dictionary. (And I agree).

On a formal level most websites seem just refer to them as that, with a clarification that it's for gold elsewhere. But there is the occasional informal usage of "guld värdepapper" (is that for ease of use, or is it a result of English syntax creeping into Swedish?).

Enligt IATE är "gold-linked security" "guldrelaterat värdepapper", dvs. värdepapper som konstrueras för att följa guldprisets värdeförändring.
