Does a high Gold/Platinum ratio prove platinum is undervalued?

No. A high ratio establishes that gold is more expensive than platinum right now. It does not mean platinum will rise — structural changes in demand and supply can keep the ratio elevated for years.

Gold/Platinum ratio: a practical guide

Q: How is the Gold/Platinum ratio calculated?

Divide the gold price per troy ounce by the platinum price per troy ounce, using prices from the same date. Both are quoted in US dollars, so the calculation is straightforward.

For most of history, platinum cost more than gold. That relationship flipped, and the two metals have diverged in ways that reflect just how different their demand stories have become. The ratio between them is a compact way to track that divergence.

The formula

GoldAlert calculates this as gold price per troy ounce ÷ platinum price per troy ounce, using closes from the same date. Because both are quoted in US dollars per troy ounce, no unit conversion is needed. A ratio of 2 means one ounce of gold currently costs twice as much as one ounce of platinum.

Why the two metals can diverge for years

Gold's demand is driven primarily by investment, central-bank reserves and jewellery. There is no major industrial application that could suddenly disappear and take a large chunk of demand with it. Supply from mining is also spread across multiple continents, so disruptions tend to be localised.

Platinum is a different story. Its largest industrial application has historically been catalytic converters for petrol and diesel vehicles — an application that is under long-term pressure from the shift to electric vehicles. Platinum is also geographically concentrated: South Africa produces roughly 70–75% of global mine supply, making the market unusually sensitive to labour disputes, power supply issues and regulatory changes in one country. When those factors work against platinum, the Gold/Platinum ratio can climb and stay elevated without any particular move in gold.

How to read a change in the ratio

A rising ratio means gold is strengthening relative to platinum. Before assuming platinum is "cheap," check what each metal actually did. Is platinum falling on automotive demand concerns? Is gold rising on geopolitical safe-haven flows? Both can push the ratio higher, but they carry very different implications.

Open the Gold/Platinum Ratio dashboard, then separately check the Platinum price page and the GoldAlert gold signal board. Compare the direction over several weeks rather than reacting to a single session.

Why relative cheapness is not the same as value

When platinum is significantly cheaper than gold by historical standards, it can attract attention as a "catch-up trade." But a sustained ratio above historical averages often reflects genuine structural change rather than a temporary mispricing. Electric vehicles reduce catalytic converter demand. That is not the kind of thing that corrects itself in a few months. Historical averages are useful reference points, but they are not price anchors.

Frequently asked questions

How is the Gold/Platinum ratio calculated?

Divide aligned gold and platinum prices, both in US dollars per troy ounce. GoldAlert uses daily scheduled closes to keep the comparison consistent.

Does a high ratio prove platinum is undervalued?

No. It only tells you the current relative price. Structural demand changes can justify persistently elevated ratios.
