What Moves the Price of Gold: Real Yields, the Dollar and Central Banks

Gold has no earnings, pays no coupon, and produces nothing. A share can be valued on its profits and a bond on its coupons. Gold cannot be valued this way at all, which is why traditional analysis struggles with it and why the commentary around it is unusually poor.

But it is not unpredictable. Its price responds to a small number of identifiable forces, and the most important one follows directly from the fact that it yields nothing.

Driver one: real yields

This is the central relationship, and understanding it explains most of gold's behaviour.

The real yield is the return on a government bond after subtracting expected inflation — the return measured in purchasing power rather than currency units.

Because gold pays no income, its principal cost is the income you forgo by holding it instead of a bond. That cost is precisely the real yield.

Real yield	What holding gold costs you	Typical effect
+3%	A great deal of forgone real return	Strong headwind
+1%	Some	Mild headwind
0%	Nothing	Neutral
−1%	The bond also loses purchasing power	Supportive
−3%	The bond loses substantially	Strong tailwind

When real yields are deeply negative, the alternative to gold is an asset guaranteed to lose purchasing power. Gold's lack of income stops being a disadvantage.

The best single indicator is the yield on inflation-protected government bonds, which gives the real yield directly rather than by estimate.

Driver two: the dollar

Gold is priced in dollars internationally. When the dollar strengthens, gold becomes more expensive for buyers using other currencies, which tends to soften demand. When the dollar weakens, the reverse.

The inverse relationship is real but looser than commonly claimed, and it can break for extended periods — particularly when both are being bought for the same reason during a crisis.

Note also that a gold price flat in dollars can be rising strongly in another currency. For a non-dollar investor, the currency component is part of the return, not a detail.

Driver three: central banks

This has become one of the more significant structural changes in the gold market.

Central banks hold gold as a reserve asset, and in recent years the official sector has been a substantial net buyer. The motivations are policy rather than investment: diversifying away from concentration in any single currency, holding an asset that is nobody's liability, and reducing exposure to reserves that could be restricted.

What makes this different from ordinary demand is that it is price-insensitive and persistent. A central bank diversifying reserves over a decade does not stop because the price rose this quarter. That creates a floor of structural demand that did not exist at the same scale before.

Driver four: risk and confidence

Gold gains during crises, though the mechanism is worth stating precisely. It is not simply that gold rises when markets fall — in acute liquidity events gold has sometimes been sold alongside everything else, because it is liquid and can be sold to meet margin calls.

The more accurate account: gold responds to a loss of confidence in currencies, in institutions, or in the ability of governments to service debt without inflating it away. That is a slower and deeper phenomenon than a market selloff.

Driver five: physical supply and demand

Source	Share of demand	Price sensitivity
Jewellery	Largest single category	High, and inverse — buyers retreat as prices rise
Investment (bars, coins, ETFs)	Substantial and variable	The main swing factor
Central banks	Growing	Low
Technology	Small	Low

Mine supply is remarkably inelastic. Bringing a new deposit into production takes many years, so a price rise does not produce more gold in any relevant timeframe. Nearly all gold ever mined still exists, so annual production adds a small percentage to the existing above-ground stock. This is why supply rarely drives price and demand almost always does.

The inflation hedge question

Gold is routinely described as an inflation hedge. The evidence is more mixed than the claim.

Over multi-century horizons, gold has broadly preserved purchasing power. Over the horizons anyone actually invests across, it has frequently failed — there have been long stretches where inflation ran high and gold delivered real losses, and other stretches where gold rose sharply with inflation subdued.

The relationship it actually holds is with real yields, not with inflation directly. Those two frequently move together, which is why the hedge story appears to work, and they sometimes diverge sharply, which is when it fails. If inflation rises and central banks raise nominal rates faster, real yields rise, and gold has historically struggled despite high inflation.

The more defensible description: gold is a hedge against negative real returns and against loss of institutional confidence, not against rising prices as such.

Practical considerations

Ways to hold it. Physical bullion involves storage, insurance and a dealer spread. Exchange-traded funds charge an annual fee and track the price closely. Mining shares add operational leverage — they amplify gold moves in both directions and carry company-specific risk that has nothing to do with the metal.

It is volatile. Gold is frequently described as safe. It has experienced drawdowns exceeding 40% and multi-year periods of decline. Safe describes its lack of default risk, not its price stability.

It produces nothing. Over long horizons, an asset generating no cash flow cannot compound in the way a productive asset can. Gold has a role as a diversifier and a hedge; it is a poor candidate for building wealth on its own.

What to watch

• Ten-year inflation-protected bond yields, as the primary signal.
• The dollar, ideally on a trade-weighted basis.
• Official sector purchases, reported quarterly.
• ETF holdings, as a proxy for Western investment demand.
• Real rate expectations, which lead the spot real yield.

The bottom line

Gold has no cash flows, so it is priced by the cost of holding it. That cost is the real yield, and the inverse relationship between the two explains gold's behaviour better than any narrative about inflation or fear.

Watch real yields. Most of the rest is commentary.
