When a bond pays 5% but prices are rising 3% a year, you are not really earning 5%. You are earning something closer to 2% in actual purchasing power. That gap between the headline yield and what is left after inflation is the real yield, and it is one of the most important drivers of gold, the dollar and risk assets. If you have ever wondered why gold sometimes falls when inflation is high, or why the dollar rallies on an inflation surprise, real yields are usually the answer.
Nominal vs real: the core idea
The key word is expected. Markets care about the inflation investors anticipate over the life of the bond, not last month's CPI print. A 4.8% nominal yield with 2.3% expected inflation gives a real yield of about 2.5%.
Where to find real yields
You do not need to calculate them yourself. In the US, the market prices real yields directly through TIPS (Treasury Inflation-Protected Securities). Their principal is adjusted for inflation, so the yield they trade at is effectively a real yield. The 10-year TIPS yield is the most widely watched real-yield benchmark in the world. Other countries have their own versions, such as UK index-linked gilts.
That gives you a second useful number: the breakeven inflation rate, which is the nominal yield minus the TIPS yield on the same maturity. It is the market's implied inflation forecast. If the 10-year Treasury yields 4.8% and the 10-year TIPS yields 2.5%, the 10-year breakeven is 2.3%.
So one nominal yield can be split into two parts:
nominal yield = real yield + breakeven inflation
When the nominal yield moves, the first question to ask is which part moved.
Why the split matters
A 30 basis point rise in the 10-year can mean two very different things:
Same headline move, opposite trading implications.
Real yields and gold
Gold pays no interest. Holding it means giving up the return you could earn on a safe bond, and the relevant return is the real one, because gold is largely held as a store of purchasing power. When real yields rise, the opportunity cost of holding gold goes up and gold tends to fall. When real yields fall, especially when they go negative, holding gold becomes relatively cheap and gold tends to rally.
For many years, the inverse relationship between gold and the 10-year TIPS yield was one of the tightest correlations in macro. It has loosened in recent years as heavy central bank buying has provided a steady bid regardless of yields, so treat it as a strong tendency rather than a law. When gold rises alongside real yields, it usually means a buyer who is not rate-sensitive is in control.
Real yields and currencies
Capital tends to flow toward the country offering the best return after inflation. So for FX, the real-yield differential often explains more than the nominal one.
Real yields and stocks
Valuations are built on discounting future cash flows, and the discount rate that matters in the long run is the real one. When real yields rise, the present value of profits far in the future falls hardest, which is why long-duration growth and tech stocks tend to struggle in rising real-yield environments while value sectors hold up better.
Common mistakes
How to track it
Put three lines on one chart: the 10-year Treasury yield, the 10-year TIPS yield and the 10-year breakeven. Free macro data sites publish all three daily. Overlay gold or the dollar index and watch which line is actually doing the moving. After a few weeks you will start to recognise the difference between an inflation scare and a genuine tightening of financial conditions.
The bottom line
Nominal yields tell you the price of money. Real yields tell you the price of money after inflation, and that is the number that actually steers gold, currencies and long-duration assets. Learn to split every yield move into its real and inflation parts, and a lot of market behaviour that looks contradictory at first starts to make sense.
Nominal vs real: the core idea
- Nominal yield is the number you see quoted: the 10-year Treasury at 4.8%, for example.
- Real yield is the return after inflation. The simple approximation is: real yield = nominal yield - expected inflation.

Why the split matters
A 30 basis point rise in the 10-year can mean two very different things:
- Breakevens rising, real yields flat. Investors are pricing more inflation but not expecting the central bank to fight it much harder. This is broadly supportive of gold and commodities and can weigh on the currency.
- Real yields rising, breakevens flat. The market expects tighter policy or stronger growth, so money is genuinely getting more expensive. This is the environment that hurts gold, pressures growth stocks and supports the currency.

- A high nominal yield can be a mirage. If a country offers 10% but runs 9% inflation, its real yield is lower than a country offering 4% with 2% inflation. Emerging-market carry trades can unravel quickly when inflation eats the headline yield.
- Rising US real yields usually support the dollar. When the Fed is expected to hold or hike while inflation expectations stay anchored, the dollar tends to strengthen against lower-real-yield currencies.
- Watch real-yield differentials in major pairs. For EUR/USD, compare US and euro-area real yields at the same maturity. For USD/JPY, Japan's deeply negative real yields for much of the last decade are a large part of why the yen was so weak.
Real yields and stocks
Valuations are built on discounting future cash flows, and the discount rate that matters in the long run is the real one. When real yields rise, the present value of profits far in the future falls hardest, which is why long-duration growth and tech stocks tend to struggle in rising real-yield environments while value sectors hold up better.
Common mistakes
- Using last month's CPI. Subtracting a backward-looking inflation number from a forward-looking yield gives a misleading real yield. Use TIPS or breakevens.
- Assuming high inflation is always good for gold. If the central bank responds aggressively and real yields rise, gold can fall even while inflation is high.
- Ignoring what drives the move. Always ask whether a change in nominal yields came from real yields or from breakevens before drawing conclusions for your trade.
- Treating correlations as fixed. The gold-real yield link and the dollar-real yield link weaken when other forces dominate, such as central bank reserve buying or a flight to safety.
