A bond yield quoted before inflation says very little. Five per cent while prices rise six per cent is a loss, and the real yield is the version of the number that accounts for that.

It matters here because Bitcoin and gold pay nothing. The case for owning them strengthens or weakens with what the alternative pays in real terms, and this is the cleanest available measure of that alternative.

What it actually measures

Which way it is heading is the whole reading. A falling real yield means the sacrifice involved in owning something that pays nothing is shrinking, and a rising one means it is growing, whatever the level happens to be.

The level can go below zero and stay there. Holding government debt then costs purchasing power as a matter of arithmetic, which is the arrangement that pushes capital toward alternatives most forcefully.

Two components move it and they move at different speeds. The nominal yield reprices continuously while the inflation side arrives once a month, so short-term swings in this reading are mostly the bond market rather than anything about prices.

Non-yielding assets are priced against what they give up

Owning something that pays nothing is a decision to forgo whatever the safe alternative pays. When that alternative pays little in real terms the sacrifice is small, and when it pays well the sacrifice is real.

This is why real yields do more explanatory work than nominal ones for gold and Bitcoin. A high nominal yield alongside high inflation is not much of a competitor, and the nominal number on its own would say otherwise.

What it does not tell you

The inflation component is an estimate of the future dressed as a measurement. Different constructions use market expectations or recent published prints and reach different answers, sometimes by enough to change the sign.

One maturity is not the curve. The relationship at ten years can differ from the relationship at two, and this view picks a point on it. A move concentrated at the short end can leave the reading unchanged while conditions have shifted.

The link is a tendency, not a rule. Hard assets have risen into rising real yields and fallen into falling ones, and the relationship holds on average over long stretches rather than reliably in any given quarter.

How to read it

Falling. The sacrifice involved in owning something that pays nothing is shrinking.

Stable. No meaningful change in what the alternative pays.

Rising. Bonds are paying more in real terms, which competes directly.

Common questions

Why adjust the yield for inflation at all?

Because a yield below the rate prices are rising is a loss in purchasing power. Only the adjusted figure says whether holding the bond preserves what you put in.

Why do falling real yields help hard assets?

Because neither gold nor Bitcoin pays anything. When the safe alternative pays little after inflation, choosing a non-yielding asset costs almost nothing.

Can the reading be negative?

It can, and it has been for years at a stretch. Holders of government debt then lose purchasing power as a matter of arithmetic rather than of risk, which pushes capital toward alternatives.

Which maturity is used?

A single point on the curve, and the relationship at that point can differ from the relationship at others. It is a representative reading rather than the whole picture.

How dependable is the link?

It is a tendency measured over long periods. Hard assets have gone the other way for months at a time without the underlying logic being wrong, because opportunity cost is one input among several and rarely the loudest.
