The real yield is the nominal yield minus the expected rate of inflation, representing the return an investor earns in purchasing-power terms. It is the purest measure of the compensation for lending money over time.
Two approaches dominate real yield measurement in practice:
TIPS are the most transparent window into real rates. The Treasury adjusts a TIPS bond's principal daily by the non-seasonally adjusted CPI, with a three-month lag. At maturity, the holder receives the greater of the inflation-adjusted principal or par. The coupon rate is fixed, but because it applies to a growing principal balance, the dollar coupon payment rises with realized inflation.
The TIPS yield is therefore a true real yield: the return above inflation that the market is willing to accept for lending to the U.S. government over the stated term. When the 10Y TIPS yield is 2.0%, investors collectively expect to earn 2.0% per year in real purchasing-power terms.
Through much of 2020 and 2021, 10Y TIPS yields turned deeply negative, reaching approximately -1.1% in August 2021 as the Federal Reserve held rates near zero and bought $120 billion per month in assets. By 2024 and into 2025, 10Y TIPS yields had normalized to a range of roughly 1.5% to 2.3%, a dramatic shift that repriced virtually every asset class. You can track the current 10Y nominal yield on YCP's 10-Year Yields page, and compare it to the breakeven to infer the market's implied real rate.
The Fisher identity links the three components of a nominal yield:
Nominal yield = Real yield + Expected inflation + Inflation risk premium
This means the 10Y nominal yield can rise for three distinct reasons: rising real growth expectations (which push up the real yield component), rising inflation expectations, or rising uncertainty about future inflation (the risk premium). Each has different implications for asset allocation and monetary policy signaling.
Disentangling these components requires a model. The Adrian-Crump-Moench (ACM) framework separates the term premium from the expected short-rate path. YCP's Premia page displays ACM decompositions so you can see how much of any given yield move is driven by the real component versus the inflation or risk-premium components.
The breakeven inflation rate, the nominal TIPS yield spread, captures expected inflation plus the inflation risk premium together, not pure inflation expectations alone. Analysts who treat the breakeven as a clean read on expected CPI are ignoring this risk premium wedge.
The 10Y real yield functions as the risk-free discount rate for all long-duration assets. A shift in real yields flows through to valuations across every asset class.
Equities: When the 10Y real yield rises from 0% to 2%, the present value of earnings expected five to ten years out falls by a computable and significant amount. This mechanism explains a large portion of the 2022 equity drawdown, particularly in long-duration growth names where a disproportionate share of value sits in distant cash flows.
Gold: Gold produces no cash flows, so its opportunity cost is the real yield directly. When real yields are deeply negative, as in 2020-2021, gold's cost of carry is low and the metal outperforms. When real yields rise sharply, as in 2022-2023, the opportunity cost of holding gold rises and the price typically falls. The relationship is not mechanical on short horizons, but it is durable across cycles.
Real estate: Rising real yields feed into mortgage rates through the Fisher mechanism, compressing affordability and applying downward pressure to price-to-rent ratios. The 2022-2023 housing affordability deterioration followed directly from the shift in real yields from below zero to above 2%.
Asset allocators who track YCP's yield curve data alongside the ACM term premium decomposition on the Premia page can separate rate moves driven by real growth repricing from those driven by inflation or risk premium shifts, which leads to materially different positioning conclusions.
