Real yields — the single most important variable

If you only track one macro variable for gold, make it real yields — the yield on inflation-protected Treasuries. Gold pays no interest, so it competes directly with real, inflation-adjusted returns on safe bonds.

The mechanical relationship

When real yields rise, holding gold has a higher opportunity cost, and the gold price tends to fall. When real yields fall — or turn negative — the opportunity cost collapses and gold typically rallies.

When the relationship breaks

Since 2022, gold has repeatedly decoupled from rising real yields. The reason: central bank buying and geopolitical demand have become large enough to override the yield signal. Read the relationship, but do not treat it as a law.

How to use it

Watch the 10-year TIPS yield alongside the gold price. Persistent divergence is a signal — usually that a non-yield driver (official-sector demand, currency stress, systemic risk) is in charge.
