Lesson 02: What Moves the Gold Price (XAU/USD)

Nine things move the gold price, and one of them explains most of what the other eight do. This lesson takes the four largest in turn — the Fed, real yields, the dollar and inflation data — and collects the remaining five where they belong, which is underneath the first four rather than beside them.

The Federal Reserve and FOMC interest rate policy

Gold pays nothing. Every dollar held in gold is a dollar not earning interest somewhere else, so the return available elsewhere is the price of holding it.

Rates rising raises that cost, which is negative for gold.
Rates falling lowers it, which is positive.
Expectations move first, exactly as Track 4's first lesson described — by the time a decision arrives, the move has usually already happened.

The consequence is that gold frequently moves sharply on days when nothing about gold changed at all. An FOMC statement that shortens the expected path of rates is a gold story, and a trader watching only the gold chart will find the move unexplainable.

What to watch on a decision day

What was priced beforehand — a hike already expected is not news.
The changes in the statement, read as a diff against the previous one.
The projections, where published.
The press conference, which reverses the initial move often enough that it is usually the more informative half.

Caution

Gold around FOMC is among the more hazardous instruments a retail trader can hold. Spreads widen, the move can reverse twice inside an hour, and gold's ordinary daily range is already large. Track 4's lesson 8 gives the sizing adjustment, and it applies here with more force than it does to a major currency pair.

10-year US Treasury yields · real yield

This is the relationship worth learning properly, because it is the most consistent one on this list.

Real yield = nominal yield - expected inflation

What each variable means:

nominal yield — The quoted yield on a government bond — the 10-year is the usual reference
expected inflation — What the market expects, readable from inflation-linked bonds

The real yield is what a risk-free investment actually earns after inflation, and it is exactly the return gold gives up. So:

Real yields	Gold, usually
Rise	Falls — the alternative got better
Fall	Rises — the alternative got worse
Negative	Strongly supported — the alternative loses purchasing power
Rise while inflation also rises	Falls, despite the inflation

That last row is the one that dismantles the inflation-hedge story from lesson 1. Inflation and gold are only related through this term, and when nominal yields rise faster than inflation expectations, the inflation is irrelevant to gold — the real yield rose, and gold fell.

Good to know

Overlay a real-yield series on the gold chart over the last few years. The relationship is loose week to week and hard to miss over months — which is the same thing Track 4 said about fundamentals generally, seen in the one place it is clearest.

DXY (US Dollar Index) — its inverse correlation with gold

Gold is quoted in dollars, so a change in the dollar changes the number even when nothing about gold has changed. This is arithmetic before it is economics.

A stronger dollar makes gold more expensive in every other currency, which dampens demand — and mechanically lowers the dollar quote.
A weaker dollar does the reverse.
The DXY measures the dollar against a basket of major currencies, and it is the usual shorthand for "the dollar" on a chart.

The inverse relationship is real and it is not a law. Both can rise together when the driver is a flight to safety that benefits the dollar and gold simultaneously, and both can fall when real yields are rising in a calm market.

DXY	Gold	What is probably happening
Up	Down	The ordinary case — usually rates
Down	Up	The ordinary case, reversed
Up	Up	A flight to safety benefiting both
Down	Down	Risk appetite improving; money leaving both

Note

Treat the dollar as the transmission mechanism rather than the cause. When gold and the DXY disagree with each other, the question to ask is what is driving the dollar — and the answer is usually rates, which puts you back at the previous section.

Inflation · CPI / Core CPI / PCE

Inflation data moves gold, and it moves it through the rate path rather than directly. Track 4's lesson 3 has the construction of these releases; what follows is how gold reads them.

Release	Gold's usual reaction	Because
Core CPI above consensus	Falls	Hawkish repricing raises expected real yields
Core CPI below consensus	Rises	The opposite
Headline hot, core in line	Little	Energy is discounted; the rate path is unchanged
Inflation falling with rates falling faster	Rises	Real yields down — the favourable combination

Row 4 is the configuration gold likes most, and it is worth recognising because it is the one that produces sustained moves rather than one-day reactions.

The other five factors

The remaining drivers matter, and each of them is smaller than the four above or acts through them.

Central bank buying. Reserve accumulation is large, price-insensitive and persistent. It sets a floor over years rather than moving a chart in an afternoon.
Geopolitical risk. Sharp, immediate, and usually short-lived. The initial spike on a headline frequently retraces within days unless the situation escalates.
ETF flows. Investor demand through gold ETFs is visible in reported holdings and is a decent read on whether an investment move is being backed by money.
Jewellery and physical demand. Seasonal and concentrated in a few large markets. It matters to the annual balance and rarely to a weekly chart.
Mine supply. Slow, inelastic and predictable. It matters over years and never explains a day.
