Why rising bond yields push stocks down — one formula and three exceptions
Equity value is future earnings discounted to today at a rate anchored to bond yields — so higher yields make the same earnings worth less
The three lines
- Equity value is future cash flows discounted to the present, and the discount rate starts from the risk-free government bond yield
- The further away the earnings, the more a yield rise cuts them — which is why growth stocks are most rate-sensitive
- The relationship inverts in three cases: growth-driven yield rises, flight to safety, and widening credit spreads
Key questions
- What connects bond yields to share prices
- A share is a claim on money a company will earn in the future, and converting future money into present money requires a divisor — the discount rate. Government bonds are treated as effectively free of default risk, so any riskier investment must clear that bar plus a premium. When bond yields rise, the floor under every valuation rises with them, and identical future earnings are worth less today.
- Why do growth stocks fall hardest
- Because their cash flows arrive later. A mature dividend payer derives most of its value from earnings in the next few years; a growth company derives most of its value from earnings five or ten years out. Discounting compounds over time, so the same rate increase cuts distant cash flows far more. That is the arithmetic behind tech leading the decline in rate-rise episodes.
- So should I sell stocks whenever yields rise
- No — the reason yields are rising changes the sign. Yields rising because growth is strengthening usually come with rising earnings estimates, and equities often rise alongside. Yields rising on inflation or fiscal concerns raise the discount rate without lifting earnings, which pressures prices. 'Rising yields mean falling stocks' is half a formula with the cause removed.
The most common causal sentence in market coverage is some version of: "Stocks fell as Treasury yields rose." Why a number from the bond market should set prices in the equity market is rarely explained.
This reference sets out that link as a single formula — and the three situations in which the formula inverts.
1. The formula — a stock is the future, converted
Buying a share is buying a claim on money a company will earn later. But 1,000 dollars five years from now is not worth 1,000 dollars today, because today's money can be put to work in the meantime.
Converting future money into present money requires a divisor. That divisor is the discount rate, and its starting point is the government bond yield.
The logic is simple. Government bonds are treated as effectively free of default risk. If a risk-free investment pays 4%, then owning shares in a company that could fail only makes sense at a meaningfully higher expected return. So every risky asset is priced as "government yield plus a premium for its risk."
When government yields rise, that floor rises for everything. The company's earnings need not change at all — the present value of those earnings falls anyway.
2. The longer the wait, the deeper the cut
Discounting compounds. This is why a yield rise does not press equally on every stock.
| Type | Source of value | Effect of a 1pt yield rise |
|---|---|---|
| Mature dividend payer | Earnings today | Least affected |
| Cyclical large cap | Earnings within a few years | Moderate |
| High-growth technology | Earnings 5–10 years out | Most affected |
| Pre-profit growth company | Eventual profitability | Most vulnerable |
Value arrives later as you move down the table — in bond language, the duration is longer. Rate increases hit long-duration assets first, which is the recurring pattern of tech leading equity declines in tightening episodes.
Real estate is rate-sensitive for the same reason: rental income is an extremely long stream of cash flows, and long streams are exquisitely sensitive to the discount rate.
3. Three exceptions
That is the textbook. In practice, yields and equities move together often enough that the textbook needs qualifiers.
| Exception | Situation | Why the formula fails |
|---|---|---|
| 1. Growth-driven yield rise | Yields up because activity and hiring are strengthening | Discount rate rises, but the numerator rises more |
| 2. Flight to safety | Crisis pushes money into government bonds, yields collapse | Yields fall and equities fall together |
| 3. Credit stress | Government yields flat while corporate yields spike | The problem is the risk premium, not the base rate |
Exception 1 is the most frequently misread. If yields are rising because the economy is improving, earnings estimates rise alongside and equities can rally. If they are rising on inflation or fiscal supply concerns, the discount rate moves without the earnings — and prices fall. The cause of the move matters more than the direction.
Exception 2 inverts the sign entirely. In a financial or geopolitical shock, capital floods into government bonds, prices rise and yields fall. Low yields in that moment are not stimulus; they are a fear gauge.
Exception 3 is invisible if you watch only sovereign yields. What companies actually pay is the government yield plus a credit spread, and stress widens the spread. If sovereign yields look calm while equities break, look at corporate credit.
4. Why the 10-year in particular
The reference rate is usually the US 10-year Treasury yield. Different maturities carry different information.
- The 2-year mostly reflects near-term monetary policy expectations — what the central bank does over the next several meetings.
- The 10-year blends long-run growth and inflation expectations, and it is the benchmark for long-horizon calculations like equity valuation and 30-year mortgages.
- The 30-year carries heavy fiscal and supply-technical noise.
So when a headline says yields rose, the maturity matters. A move confined to the 2-year is a policy-expectation story. A move led by the 10-year points to growth, inflation or fiscal concerns.
5. How this reaches markets outside the US
| Channel | Mechanism | Lag |
|---|---|---|
| Valuation | US 10-year → global risk-asset discount rate → local indexes | Same day |
| Currency and flows | Rate differentials → exchange rate → foreign buying and selling | Same day to days |
| Local rates | US yields → domestic sovereign yields → corporate and bank lending | Weeks |
| Households | Loan rates → interest burden → consumption | Months |
Local government yields drive local equities through the same mechanism, but in open economies long-term rates largely follow global rates. That is why an investor in Seoul or São Paulo still watches the US 10-year.
6. Common misreadings
"Falling rates are always good for stocks." Exception 2 says otherwise: in a crisis, yields and equities fall together. If rates are falling because a recession is feared, that is not stimulus.
"Rising yields are good news for bondholders." The opposite, for existing holders. Higher yields mean lower prices on bonds already owned. New buyers benefit; incumbents take a mark-to-market loss.
"Nominal rates are what matter." The burden that matters is the real rate — nominal minus expected inflation. A 5% rate with 4% expected inflation is a 1% real cost. That is how equities sometimes hold up while rates and prices rise together.
7. What remains unverified
The correlation between yields and equities changes sign across periods and regimes. This piece describes a mechanism; it does not forecast direction. Duration and discount-rate effects also vary widely by sector and by the assumptions used, so the table above should be read as tendency rather than rule.
