Platinum price history — a quick overview
Over the past two decades, platinum has moved from under $400/oz in the early 2000s to record highs above $2,000/oz, driven by inflation, central-bank buying and safe-haven demand. Local prices in Japan also reflect the Japanese Yen/USD exchange rate, so periods of currency weakness amplify the rise of platinum prices for local buyers.
