Spread trading between Gold (XAU/USD) and Platinum (XPT/USD) is a staple strategy among institutional commodity arbitrageurs looking to generate alpha independent of market direction.
1. The Platinum-to-Gold Valuation Divergence
Platinum is approximately 30 times rarer than gold in the Earth's crust. For decades prior to 2011, Platinum commanded a $200 to $800 premium over gold. As central banks began de-dollarizing and accumulating gold exclusively, gold decoupled to all-time highs while platinum remained tied to automotive catalytic converter demand.
2. Executing the Spread Trade
When the Gold/Platinum ratio reaches historical upper standard deviation extremes on weekly charts, quantitative traders buy XPT/USD and sell XAU/USD in equal notional dollar sizes. This market-neutral trade generates profit as the valuation spread narrows back toward historical norms.
