What is real yield?

Real yield is the return on a bond after subtracting expected inflation. The cleanest measure is the yield on Treasury Inflation-Protected Securities (TIPS), which pays a real coupon plus an inflation adjustment. The 10Y real yield is one of the most important rates in markets: it discounts long-duration cash flows (growth stocks), prices gold (gold pays no yield, so real yield is its opportunity cost), and gauges Fed restrictiveness. Rising real yields tighten conditions; falling real yields ease them.

  • TIPS yield - Direct market measure of real yield.
  • 10Y real yield - Discount rate for long-duration assets.
  • Gold's opportunity cost - Higher real yield = lower gold.
  • Fed restrictiveness - Real fed funds vs neutral real rate.

Two ways to measure

  1. TIPS yield - direct market price of real return
  2. Nominal yield − breakeven inflation - derived measure

Both should agree. When they diverge, liquidity in TIPS is the issue.

Why it matters

  • Growth stocks - real yield is the discount rate. Rising real = multiple compression.
  • Gold - gold pays no yield, so real yield is the opportunity cost of holding it.
  • EM equities - real yield differential drives capital flows.
  • Fed restrictiveness - real fed funds rate vs estimated r* (neutral real rate).

What to watch

  • 10Y real yield - primary discount rate
  • 5Y real yield - cyclical sensitivity
  • Real fed funds rate - fed funds minus core PCE - the actual policy stance
