Silver investing explained: the gold-silver ratio, volatility and how to buy

Original content · last updated 2026

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:

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.

What is the gold-silver ratio, and why watch it?

The gold-silver ratio = price of one ounce of gold ÷ price of one ounce of silver — how many ounces of silver one ounce of gold is worth. Historically it moves within a range: when the ratio is high, some investors see silver as "cheap" relative to gold; when low, the opposite. Some use it as a reference for allocation or switching — e.g. adding silver when the ratio is very high and rotating back to gold when it falls.

How is it calculated and read? Silver here is converted from the international price (USD/oz) × USD/HKD into per-tael and per-gram reference values, with source and update time. The ratio is just one of many reference indicators, not a trading signal, and guarantees no return; silver is generally more volatile than gold, so understand the risk before entering.
