What is real yields?

What it means

Gold pays no interest, so its opportunity cost is whatever a safe interest-bearing asset yields after inflation. When real yields rise, holding gold becomes more expensive in that sense and the price tends to fall; when they fall or turn negative, the reverse.

Why it matters

The relationship is usually measured against inflation-protected government bond yields, and it is strong enough over months and years to be the default macro explanation for large gold moves. It is much weaker intraday, where positioning and flow dominate.

What this changes in practice

For a bot trading M1 to M15 bars this is context rather than signal. It explains why a persistent directional bias exists in a given period without being tradable on its own — which is a useful distinction, because a system built on a genuine macro relationship at the wrong timeframe will underperform a much simpler one that respects the timeframe it actually operates on.
