Understanding XAUUSD
XAUUSD (or XAU/USD) is the ticker for the spot gold–US dollar pair. "XAU" is the ISO 4217 code for gold (from the Latin for gold); "USD" is the US dollar. The price you see is how many US dollars it takes to buy one troy ounce of gold. So when the quote is 2,650.00, that means one troy ounce of gold costs 2,650 US dollars.
This pair is one of the most traded in the world. It is used by central banks, institutional investors, and retail traders for hedging, speculation, and diversification. Gold is seen as a store of value and a hedge against inflation and currency debasement, while the US dollar is the world's reserve currency. Trading XAUUSD gives exposure to that relationship without owning physical metal.
Several forces move the price. The US dollar: when the dollar strengthens, XAUUSD often falls, and when the dollar weakens, gold in USD often rises. Real interest rates (nominal rates minus inflation) matter too—higher real rates tend to weigh on gold; lower real rates or negative real rates often support it. Geopolitical risk and financial stress increase safe-haven demand and can push gold up. Central bank buying or selling, ETF flows, and physical demand also affect supply and demand.
