Real Yield
A real yield is a bond yield after inflation. It can be calculated from expected inflation, or observed directly in inflation-protected bonds such as TIPS. Rising real yields tend to weigh on gold and long-duration growth stocks.
A 5% bond yield sounds good — unless prices are rising 6% a year. What matters for your purchasing power is the real yield: the return after inflation. Real yields are watched closely by investors because they shape the true cost of borrowing and the appeal of assets such as gold and growth stocks. This entry explains how real yields are measured and why they matter.

Real yields in plain words
Inflation reduces what money can buy over time.1 A real yield subtracts that loss: real yield ≈ nominal yield − inflation. A 4% yield with 3% inflation is a real yield of about 1%. See Inflation.
Some bonds show real yields directly. The principal of Treasury Inflation-Protected Securities rises and falls with a consumer price index, so their quoted yield is a return above inflation.2 See Treasury Inflation-Protected Securities.
How to work with real yields, step by step
Start with the nominal yield
The ordinary bond yield. See Yield to Maturity.
Choose an inflation measure
Expected inflation, or a recent index such as the CPI.3
Subtract
Real yield ≈ nominal yield − inflation.
Or read it from TIPS
TIPS yields are market-based real yields.
Watch the trend
Rising real yields raise the true cost of money.
Link to other assets
Gold and long-duration growth stocks often react to real yields. See Duration.
Worked examples
Example 1 — Positive real yield
PositiveA 10-year bond yields 4.5%; expected inflation is 2.5%.
| Real yield | 4.5% − 2.5% ≈ 2.0% |
Investors earn about 2% a year above inflation.
Example 2 — Negative real yield
NegativeA savings bond yields 3% while inflation runs at 5%.
| Real yield | 3% − 5% ≈ −2% |
Even with positive interest, purchasing power shrinks.
Example 3 — Real yields and growth stocks
ValuationReal yields rise from 0.5% to 2.0% over a year.
| Present value of distant profits | Lower |
Higher real yields reduce what investors pay today for profits far in the future. See Interest Rate.
Nominal vs. real yield
| Aspect | Nominal yield | Real yield |
|---|---|---|
| Includes inflation? | Yes | No — inflation removed |
| Where to see it | Ordinary bonds | TIPS or nominal minus inflation |
| Can be negative? | Rarely | Yes, when inflation exceeds the yield |
| Tells you | Cash return | Purchasing-power return |
Why investors watch real yields
True return
Whether savings beat inflation.
Asset valuation
Real yields feed into valuations of stocks and bonds.
Policy signal
Central-bank tightening often lifts real yields. See Central Bank.
Inflation expectations
Compared with nominal yields, they show expected inflation. See Breakeven Inflation.
Advantages and disadvantages
Advantages
- Shows the return that actually matters for purchasing power.
- Observable directly in inflation-protected bonds.
- Useful link between bonds, stocks and commodities.
Disadvantages
- Depends on which inflation measure is used.
- Expected inflation is an estimate.
- Relationships with other assets can change.
Going deeper
Read as far as you need. Each level builds on the one before it.
Money illusion
Beginner
People tend to judge returns in nominal terms. A 5% return during 6% inflation still leaves you poorer in real terms.
Ex-ante vs. ex-post
Intermediate
An ex-ante real yield uses expected inflation; an ex-post real yield uses the inflation that actually happened. They can differ a lot after surprises.
Exact formula
Advanced
Precisely, (1 + real) = (1 + nominal) ÷ (1 + inflation). The simple subtraction is a close approximation when rates are low.
Common mistakes
Ignoring inflation
Nominal returns can hide real losses.
Mixing inflation measures
Be consistent.
Assuming real yields cannot be negative
They often have been.
Treating relationships as fixed
Asset links to real yields vary.

Key points to remember
- Real yield ≈ nominal yield − inflation.
- TIPS yields are market real yields.
- Real yields can be negative.
- They measure the purchasing-power return.
- Rising real yields often pressure gold and growth stocks.
