Switzerland is the world's largest gold refining center, processing roughly 70% of the world's gold. Swiss refineries like Valcambi, PAMP, and Argor-Heraeus are trusted names in the global gold market. The Swiss Franc is itself considered a safe-haven currency, and gold priced in CHF tends to be less volatile than in other currencies. Switzerland also has a strong tradition of gold coin collecting, with the Vreneli being a popular choice.
