Understanding the Gold Price in US Dollars
The gold price in USD — quoted as XAU/USD — is the world's most-watched commodity price. It represents the cost of one troy ounce of pure gold (999.9 fine) for immediate delivery on the spot market. The price is determined continuously through trading on COMEX in New York, the London Bullion Market (LBMA), and electronic OTC markets across Asia, the Middle East, and Europe — 24 hours a day, 5 days a week.
Because the US Dollar is the world's primary reserve currency, virtually all international gold transactions are settled in USD. All other currency-denominated prices — EUR, GBP, INR, AED — are derived from the USD spot price converted at current exchange rates.
What is XAU/USD?
XAU/USD is the ISO ticker for the gold-to-dollar exchange rate. XAU is the ISO 4217 currency code for gold, derived from the chemical symbol Au (Latin: aurum). It is traded on COMEX futures, the spot OTC market, and via ETFs like SPDR Gold Shares (GLD) and iShares Gold Trust (IAU).
What moves the XAU/USD price?
- US Dollar strength: Gold and the USD share a strong inverse relationship — a weaker dollar makes gold cheaper for international buyers, lifting demand and price.
- Federal Reserve policy: Higher interest rates raise the opportunity cost of holding non-yielding gold, typically pressuring prices lower.
- Inflation expectations: Gold is a classic store of value. Rising CPI or PCE readings tend to support higher gold prices.
- Geopolitical risk: Wars, sanctions, and financial crises drive capital into safe-haven assets, with gold at the top of the list.
- Central bank buying: China, India, Poland, and Turkey have been accumulating gold reserves, adding consistent demand pressure.
- ETF flows: Large-scale buying or selling in GLD and IAU moves the physical demand balance at scale.
Gold weight conversions in USD
While the global standard is the troy ounce (31.1035 g), retail buyers in different regions track other units:
- Per gram: Divide spot price by 31.1035 — common for small retail purchases and Indian jewelry markets.
- Per kilogram: Multiply gram price by 1,000 — the standard for central bank reserves and large institutional trades.
- Per tola: 11.6638 g — traditional unit used across India, Pakistan, and the Gulf states.
- Per troy pound: 12 troy ounces — used in some wholesale and refinery contexts.

Spot price vs. physical gold in USD
The spot price shown here is for immediate professional-market settlement — it is not the retail price. Physical gold is sold at spot plus a dealer premium of typically 2–8% for bullion bars and coins. Jewelry carries much higher premiums due to fabrication and retail margins.
