What does the gold to platinum ratio tell you?
The gold to platinum ratio tells you how many ounces of platinum one ounce of gold buys. A reading above 1.0 means gold carries the premium; below 1.0 means platinum does. For most of modern history the ratio sat below 1.0, because annual platinum mine supply is a small fraction of gold's and the metal enjoyed strong jewelry and autocatalyst demand. That relationship flipped in 2015, and gold has held the premium ever since.
The gap has since widened to historic extremes. In 2024, gold's LBMA annual average of $2,386 per ounce stood against a platinum annual average near $956, putting the full-year ratio around 2.5. Watching whether the ratio expands or contracts is a quick way to gauge how markets are weighing gold's monetary demand against platinum's industrial demand.
Is a high gold to platinum ratio a signal that platinum is cheap?
Some value-focused investors read a historically high gold to platinum ratio as evidence that platinum is underpriced relative to gold, and reversion toward the old parity has been a popular thesis ever since the ratio pushed above 2.0. The counterargument is structural: diesel vehicles, long the largest platinum catalyst market, have lost share for a decade, while gold's central bank bid has no platinum equivalent.
Both readings of the same number can be defended, which is why the ratio works better as context than as a standalone signal. Platinum's own fundamentals, including concentrated South African supply, substitution for palladium in gasoline catalysts, and potential hydrogen fuel cell demand, will decide whether the gap ever closes. This is educational context, not investment advice.
