Silver investing explained: the gold-silver ratio, volatility and how to buy
Silver is often called "the poor man's gold", but its role is far richer. Silver is at once a safe-haven asset and an industrial metal, and its price often swings more than gold. For investors entering precious metals with a smaller budget, silver is well worth knowing.
How is the silver price calculated?
Like gold, international silver is quoted in "US dollars per ounce". Converted to HKD per tael:
Reference per tael = per gram × 37.429
Because silver's unit price is far below gold, labour and markup take a larger share at retail, so the bid-ask spread on physical silver (bars, coins) is usually wider than gold.
What is the "gold-silver ratio"?
The gold-silver ratio = gold price per oz ÷ silver price per oz, i.e. "how many ounces of silver one ounce of gold can buy". Historically it has long sat between 50 and 80, and exceeded 100 at extremes.
- High ratio (e.g. > 90): some see silver as relatively cheap, or a catch-up opportunity.
- Low ratio (e.g. < 50): silver is relatively expensive.
The ratio is only a reference indicator; it does not guarantee direction nor constitute a trading signal.
