Real yields (real interest rates)

Real yields are the interest rate left after expected inflation, and for a long stretch they moved gold in near lock-step reverse. That relationship just broke.

Real yields are the interest rate left after you strip out expected inflation — the nominal yield on a bond minus the market's breakeven inflation estimate for the same maturity. It's the actual return a lender locks in once rising prices get taken out of the math, and it's the number that decides whether holding cash-like assets pays or merely keeps pace.

For gold traders this is the textbook anchor. Gold pays no coupon and no dividend, so every basis point of real yield is a direct opportunity cost of holding it instead of a bond. When real yields climb, gold should fall. The metal gets more expensive to hold relative to what you're giving up by not owning yield. For a long stretch that relationship behaved close to the model, real yields and gold moving in near-lockstep opposite directions.

Then it stopped. The relationship weakened as gold pushed to fresh highs while real yields, instead of falling to support the rally, rose alongside it. The correlation drifted from strongly negative toward something far noisier, at times outright positive. Two series that were supposed to move as mirror images started moving together instead.

This is the caution built into any intermarket analysis. A correlation measured over a long run of years describes how two markets behaved under one regime, and regimes end. Conviction built up over that many years doesn't come with a warning label. Central bank buying, currency debasement fears, and reserve-diversification demand can all push gold higher for reasons that have nothing to do with the cost of money. Once enough of that demand shows up, the old anchor stops anchoring.

None of this makes real yields useless. It means treating any single cross-market relationship as a permanent lever is a bet that the regime holds steady, and regimes don't announce their own expiration. Real yields and gold, a stock-bond correlation: the same wager sits under both. The same caution applies to strategies that harvest a volatility risk premium on the assumption that sellers always get paid. That payout is conditional on a regime too, and regimes end without notice. Watch the level, watch the trend, but don't assume an old chart still describes today.
