Understanding GOLD/USD (XAUUSD)

What is XAUUSD?

XAU is the ISO code for gold (one troy ounce of gold) and USD is the US dollar. The XAUUSD symbol therefore represents the price of one ounce of gold expressed in dollars. When you see "XAUUSD = 2,650", it means one troy ounce of gold (about 31.1 grams) is worth 2,650 dollars.

Trading XAUUSD does not mean buying physical gold: through a broker like XM, you speculate on price movements, up (long position) or down (short position), using CFDs (contracts for difference).

Why is gold so popular with traders?

• Huge liquidity: gold is one of the most traded assets in the world, making it easy to enter and exit positions.
• Attractive volatility: XAUUSD moves enough each day to offer opportunities, unlike slower assets.
• Safe-haven asset: in times of crisis or uncertainty, investors turn to gold, creating strong trends.
• Extended hours: the market is open 24 hours a day, Monday to Friday, with identifiable activity peaks.

The 5 factors that move the price of gold

1. The US dollar

Since gold is priced in dollars, the two generally move in opposite directions: when the dollar strengthens, gold becomes more expensive for foreign buyers and its price tends to fall. Keep an eye on the dollar index (DXY).

2. Fed interest rates

Gold pays no interest. When the US Federal Reserve raises rates, bonds become more attractive and gold suffers. Conversely, low or falling rates support the yellow metal. Fed meetings (FOMC) are high-volatility events.

3. Inflation

Gold is historically seen as a hedge against inflation. High inflation or inflationary fears push investors toward gold. The US CPI report is therefore a crucial statistic.

4. Geopolitics and crises

Conflicts, trade tensions, banking crises: every episode of global uncertainty reinforces gold's safe-haven status and can trigger rapid rallies.

5. Central banks

Central banks (notably in China, India, and Russia) buy gold to diversify their reserves. These massive purchases support long-term demand.

What are the best times to trade XAUUSD?

The gold market follows the major financial sessions:

• London session (3 a.m. – 11 a.m. ET): strong activity, especially around the gold fix.
• New York session (8:30 a.m. – 4 p.m. ET): the volatility peak, especially during US economic releases.
• London–New York overlap (8:30 a.m. – 11 a.m. ET): often the most active window of the day, favored by intraday traders.
• Asian session: generally quieter, more prone to ranges.

Always check the economic calendar before trading: releases like the NFP (US jobs report), CPI, or Fed speeches can move gold by tens of dollars in a matter of minutes.

Key takeaways

• XAUUSD = the price of one ounce of gold in US dollars.
• Gold reacts mainly to the dollar, Fed rates, inflation, and crises.
• The best trading windows are during the London and New York sessions.
• Never trade blindly through major economic releases without understanding their impact.
