Rising yields can also reduce the market price of existing fixed-rate bonds. But neither effect dictates what stocks will do next or means retirees should automatically change their allocations: expected company profits, risk premiums, time horizon and spending needs all matter.
Why do Treasury yields matter to stock valuations?
A stock is valuable partly because of the cash its owner expects to receive in the future, such as dividends or earnings that support future growth. One way investors estimate its value is to discount those expected future payments back to today. In simplified form:
Present value = expected future cash flow ÷ (1 + discount rate)number of periods
If the discount rate rises while expected cash flows and other assumptions stay the same, their present value falls. Treasury yields matter because government securities are commonly used as a reference for a comparatively safe return. The Federal Reserve describes an asset’s price as the discounted value of expected future payoffs, and says a risky asset’s discount rate includes both the safe-asset interest rate and a risk premium. See the Federal Reserve’s Financial Stability Report: Asset Valuations.
#1 Best Overall
That mechanism helps explain why rising yields can put pressure on stock valuations, especially for companies whose expected profits are further in the future. It is not a mechanical forecast. Company earnings expectations, interest rates and investors’ willingness to bear risk can all shift together, offsetting or reinforcing one another. The Federal Reserve notes that even large, unexpected monetary-policy rate changes have had modest effects on asset prices relative to their overall variation; it does not establish a universal percentage decline in stocks for a given Treasury-yield increase.
What is the difference between nominal yields, real yields and the equity risk premium?
These terms describe related but distinct parts of the comparison investors make between stocks and Treasuries.
Rank #2
| Measure | What it represents | Why it matters |
|---|---|---|
| Nominal Treasury yield | The stated yield, which reflects real-rate and expected-inflation influences. | It is a visible reference for returns available from Treasuries, but does not isolate inflation-adjusted return. |
| Real Treasury yield | A market yield on Treasury Inflation-Protected Securities (TIPS), adjusted for inflation expectations as reflected in TIPS markets. | It is more directly relevant to real discounting, but is still a market rate rather than a guaranteed forecast of future inflation or returns. |
| Equity risk premium | The extra return investors expect for holding risky stocks rather than a safer asset; it cannot be directly observed. | If perceived stock risk changes, the return investors require may change even when Treasury yields do not. |
| Expected company cash flows | Investors’ estimates of future profits and other payments to shareholders. | Improved profit expectations can support valuations; weaker expectations can add pressure, independent of the rate move. |
The Federal Reserve discusses a rough indicator formed by subtracting the expected 10-year real Treasury yield from the S&P 500 forward earnings yield—the index’s forward expected earnings divided by its price. It is a proxy for expected excess equity returns over a risk-free rate, not a complete fair-value test or a forecast. A higher real yield can weigh more heavily on the present value of distant expected cash flows when other assumptions are unchanged, but shifts in growth expectations or risk appetite may dominate in either direction.
How should you read a Treasury yield quote?
A yield figure is meaningful only with its maturity, type and observation date. For example, a 10-year nominal yield and a 10-year real yield are not interchangeable. The U.S. Treasury publishes nominal and real par yield curves for multiple maturities; the real curve uses TIPS quotations. Treasury says the nominal curve uses inputs obtained by the Federal Reserve Bank of New York at approximately 3:30 p.m. each business day. The curves are estimated from indicative closing market bid quotations on recently auctioned securities, not a record of completed transactions.

Treasury’s constant-maturity yields are interpolated values at fixed maturities. Since December 6, 2021, the official par yield curves have used a monotone convex spline method. Check the Treasury’s Daily Treasury Rates or its Interest Rate Statistics page for a dated figure; state the observation date, maturity and whether it is nominal or real rather than citing a rate without context.
What happens to bonds when market yields rise?
For existing fixed-rate bonds, market prices generally move in the opposite direction from market interest rates. If newly issued bonds offer higher rates, an older bond with a lower fixed coupon may need to sell at a lower price to compete. If you hold an individual bond to maturity, its market price can still fluctuate before then; selling early makes the prevailing price relevant. The SEC explains this relationship in its bulletin, When Interest Rates Go Up, Prices of Fixed-Rate Bonds Fall.
Similar bonds with longer maturities generally carry more interest-rate risk than shorter-maturity bonds because more of their fixed payments lie further in the future. A bond fund is different from a single bond held to maturity: the fund’s holdings can turn over, so it does not have one maturity date at which an investor is promised repayment of the fund’s principal. FINRA’s bond overview explains bond features and risks.

Not automatically. Higher yields may improve the income available on newly invested cash or bonds, while lower market prices can hurt existing fixed-rate bond holdings. Meanwhile, selling stocks solely because yields rose turns one market input into a timing rule, even though yields alone do not determine future stock returns.
The SEC describes asset allocation as dividing investments among categories such as stocks, bonds and cash. Its guidance identifies time horizon, risk tolerance, diversification and rebalancing as relevant factors. An investor closer to a goal may choose to hold more bonds relative to stocks to reduce risk, while accepting lower growth potential; that is a general trade-off, not a prescription for every retiree. See the SEC’s guides to asset allocation, diversification and rebalancing and asset allocation and diversification.
Before making a change, consider the role each holding serves in your plan:
- Near-term spending: Identify money needed soon and how you would cover withdrawals during a market decline.
- Time horizon: Separate near-term expenses from goals that are still years away; the latter may need continued growth potential.
- Interim losses: Consider how much fluctuation you can tolerate without abandoning the plan.
- Bond exposure: Compare maturities and distinguish an individual bond you intend to hold from a fund whose holdings change.
- Portfolio balance: Use a diversified allocation and a deliberate rebalancing approach rather than reacting to one day’s yield movement.
Stocks, bonds and cash serve different purposes and carry different risks. A yield change may be a reason to review whether an allocation still fits your goals and cash-flow needs, but it cannot by itself identify the right allocation for an individual investor.
