Treasury Yields at a 24-Year High: Mortgages and Stocks
Why higher Treasury yields raise mortgage costs and make bonds more competitive with stocks, with payment examples and a breakdown of mortgage spreads.
Think of Treasury yields as a starting wage for money. Investors can lend to the U.S. government, so other borrowers have to compete with what it offers. When that safe alternative pays more, borrowing generally gets more expensive. That includes borrowing to buy a house.
On Wednesday, October 7, the 10-year Treasury yield touched 5.35%, its highest level since 2002, according to Cboe's market update. Mortgage pricing moved sharply during the day. Mortgage News Daily's dated report put its average top-tier 30-year fixed rate at 7.59% after lenders improved their initial offers, up 0.03 percentage point from the previous day.
What does the government's borrowing cost have to do with your house or your 401(k)? The return on relatively safe investments helps set the terms on which people borrow and invest elsewhere. That connection explains why higher Treasury yields can squeeze home buyers and give stocks tougher competition.
Key Takeaways
- The 10-year Treasury touched 5.35% on October 7, a 24-year high (Cboe). Mortgage News Daily's end-of-day 30-year reading was 7.59%.
- Mortgage rates generally track the 10-year Treasury, with an additional spread for mortgage risks, fees and lender margins. Changes in that spread can offset or amplify Treasury moves.
- The mortgage spread has narrowed since 2023; higher Treasury yields explain the past year's rise in mortgage rates. The average spread fell from 2.85 percentage points in 2023 to 1.97 in 2026 through October 1. The calculations and data appear below.
- On a $400,000 loan, Freddie Mac's October 1 rate of 7.28% costs about $251 more a month than its 6.34% rate a year earlier. At the separate 7.59% daily reading, the difference is about $335.
- Treasury yields around 5.3% make bonds more competitive. The S&P 500's roughly 5.26% forward earnings yield is a useful comparison, but it is neither a cash payout nor the expected total return on stocks.
Treasury Yields Set a Benchmark for Borrowing
Suppose one employer raises its starting wage. Other employers looking for similar workers may have to offer more, too. Investors make a comparable choice: why lend to a riskier borrower if a Treasury offers an attractive return?
The comparison needs some boundaries. Maturity, taxes, liquidity and the timing of payments all matter. A ten-year Treasury isn't a universal minimum rate for every loan. It is, however, a widely watched benchmark for long-term borrowing, including mortgages.
FRED's daily 10-year reading was 5.31% on October 5 and 5.27% on October 6 (DGS10). Those dated daily observations are distinct from October 7's 5.35% intraday high. The broader point is that a benchmark near 5.3% makes a home loan harder to price cheaply.

How a Bond Market Number Reaches Your Kitchen Table
The link between Treasury yields and mortgages comes from how loans are financed. The Dallas Fed's explanation of mortgage pricing describes the role of Treasury yields, repayment timing and mortgage-specific risks.
Step 1: Your lender may sell your loan. Many home loans are pooled into mortgage-backed securities, whose payments come from homeowners' monthly checks. Agency mortgage securities carry guarantees from Fannie Mae, Freddie Mac or Ginnie Mae. Selling loans frees up lenders' money for further lending.
Step 2: The buyers compare investment choices. Banks, pension funds, insurers and other investors can buy mortgage securities or Treasurys. Mortgage pricing has to offer enough compensation for the differences between them.
Step 3: Thirty years on paper doesn't mean thirty years of payments. Homeowners repay principal each month and may sell or refinance before the final payment. That shortens a mortgage's effective life, making the 10-year Treasury a useful benchmark. Its interest-rate sensitivity also changes as refinancing becomes more or less likely.
Step 4: The spread bridges the difference. We can describe the quoted mortgage rate as the 10-year Treasury yield plus a spread. This is an accounting breakdown, not a rule that the spread must stay fixed. A Treasury rise tends to lift mortgage rates, but a narrowing spread can offset some of it.
The two lines aren't identical, but their broad movements are closely related. The 10-year averaged about 0.6% in mid-2020, while Freddie Mac's mortgage rate reached a record low of 2.65% in January 2021. By early October 2026, both were more than four and a half percentage points above those levels.
What the Spread Pays For
Agency guarantees address much of the default risk for investors in those mortgage securities. They don't remove every source of uncertainty.
The refinancing trap. When rates fall, homeowners have an incentive to refinance. Investors get repaid just when reinvesting the money may earn less. When rates rise, refinancing slows and investors can be left holding below-market loans for longer. That uncertainty about repayment is called prepayment risk.
Volatility. Bigger swings in interest rates make repayment timing harder to predict and the borrower's refinancing option more valuable. Investors may demand more compensation.
The costs in between. Servicing payments, guaranteeing securities and originating loans cost money. Those fees and lender margins also contribute to the gap between a retail mortgage rate and the Treasury benchmark.
Using the method below, the spread averaged 1.76 percentage points across the available observations beginning in 1971. In 2023 it exceeded 3 points on four weekly observations and reached about 3.11 on June 1, the widest under this calculation since July 1986. A historical average is a reference point, not a minimum or a guarantee of where the spread should settle.
The Surprise in the Data: Treasurys Explain the Increase
I split Freddie Mac's weekly mortgage rate into a Treasury benchmark and the spread above it. That helps distinguish a higher general cost of borrowing from a wider mortgage-specific premium.
The average spread was 2.85 percentage points in 2023, 2.52 in 2024 and 2.30 in 2025. For 2026 through October 1, it was 1.97. Compare four snapshots: the 2021 mortgage-rate low, the 2023 peak, a year ago and now.
How I calculated it: I used the seven calendar days ending on each Freddie Mac release date. First, I averaged the Treasury yields available in that window. Then I subtracted that average from the weekly mortgage rate to get the spread. I averaged the weekly spreads for each year and for the full 1971–2026 period.
The data come from MORTGAGE30US and DGS10, retrieved October 8. The last mortgage release included is October 1.
My seven-day window ends on the release date. Freddie Mac's current survey covers the prior Thursday through Wednesday, so the dates don't match exactly. Its survey method has also changed over time (Freddie Mac). This spread compares the rate borrowers pay with a Treasury benchmark. It includes fees and lender margins as well as payment for risk.
On October 2, 2025, the mortgage rate was 6.34%, consisting of a 4.15% Treasury benchmark and a 2.19-point spread. On October 1, 2026, the corresponding figures were 7.28%, 5.24% and 2.04 points. Using unrounded values, the Treasury component rose about 1.09 points, while the spread narrowed about 0.15 point. Together, they explain the 0.94-point mortgage-rate increase.
In this decomposition, the Treasury increase more than accounts for the mortgage increase. The smaller spread partly cushioned borrowers. This doesn't establish that every lender's pricing is competitive, but it shows that a widening aggregate spread wasn't responsible for the year-over-year rise.
There may be less scope for a repeat of the spread compression seen since 2023. Still, the long-run average isn't a floor: the spread can narrow further or widen again. Cheaper mortgages could come from lower Treasury yields, a smaller spread, or both.
What 7.59% Does to a Family Budget
Percentages are abstract. Monthly payments aren't. Here is what the same $400,000, 30-year fixed loan costs at three dated rates, counting principal and interest only:
| Mortgage rate | Where the rate comes from | Monthly payment | Total interest over 30 years |
|---|---|---|---|
| 6.34% | Freddie Mac, October 2, 2025 | $2,486 | $495,079 |
| 7.28% | Freddie Mac, October 1, 2026 | $2,737 | $585,266 |
| 7.59% | Mortgage News Daily, October 7, 2026, end of day | $2,822 | $615,758 |
Author's calculations using standard monthly amortization, with results rounded after calculation. Interest totals assume all 360 scheduled payments, with no refinancing or early repayment. Taxes, insurance, mortgage insurance and fees are excluded. Freddie Mac's weekly series and Mortgage News Daily's daily index use different methods; the first two rows are the comparison within the same series. Sources: Freddie Mac via FRED and Mortgage News Daily's October 7 report.
On the Freddie Mac figures, the same loan costs about $251 more a month than a year earlier, roughly $3,000 a year. Keeping it for the full term would mean about $90,000 more interest. At the separate 7.59% daily reading, the monthly difference from 6.34% is about $335.
Seen another way, the payment that covered a $400,000 loan at 6.34% covers about $352,500 at 7.59%. That's roughly $47,500 less borrowing capacity for the same monthly principal-and-interest budget.
For a simple budget illustration, suppose principal and interest alone take 28% of gross income. The income required rises from about $106,600 to $120,900. Actual housing expenses include taxes, insurance and possibly other charges, so a budget that includes those costs requires more income. This illustration isn't a lender's approval threshold.
Buyers are facing that pressure. Zillow's September market report, published October 6, showed newly pending listings down 8.5% from a year earlier. These are listings moving into pending status, not completed sales. The report attributed the slowdown to both high mortgage rates and the seasonal fall slowdown.
If you're in the market, three practical points follow:
- Discuss a rate lock before choosing to float. A lock can protect against increases while you close, but its duration, extension charges and treatment of falling rates matter. The CFPB's rate-lock guide sets out the questions to ask.
- Compare several lenders on the same terms. Look at rates, points and fees together. A lower quoted rate may involve a larger upfront payment.
- Be skeptical of quick-relief forecasts. Watch both Treasury yields and the mortgage spread. Our CPI, PPI and Fed rate decisions FAQ explains why economic releases can change the outlook.
Why 5% Treasurys Give Stocks Tougher Competition
Higher yields also change the choices facing investors. Someone who needs predictable nominal cash flows may find a Treasury more attractive when its yield is around 5.3%. Whether to buy it still depends on the investor's time horizon, liabilities and alternatives.
Inflation matters, too. August consumer prices were 3.4% above a year earlier, according to the archived BLS release. A nominal yield around 5.3% exceeds that backward-looking inflation reading by roughly 1.9 percentage points. That gap isn't a guaranteed future real return: inflation over the bond's life is still unknown.
What the Earnings-Yield Comparison Can Tell You
A stock's earnings yield is earnings divided by price, the inverse of its P/E ratio. FactSet's October 2 report put the S&P 500's forward P/E at 19.0, based on Wednesday's closing price and earnings estimates. That implies an earnings yield of 100 ÷ 19.0 = 5.26% (FactSet Earnings Insight). Our guide to P/E and forward P/E explains the calculation.
For a comparison on the same date, the chart uses September 30's 5.29% Treasury observation. It doesn't mix October 7's intraday high with an earlier stock valuation.
The numbers are close, but they measure different things. A Treasury's yield to maturity is based on its price and promised payments. A stock earnings yield compares expected company profits with the price investors pay for the shares. Those profits can grow or shrink. Shareholders may receive only part of them as cash.
The small gap alone isn't a reason to sell stocks. It doesn't tell us which asset will earn more over time. The useful point is that bonds now offer more income to investors who want predictable payments. A higher yield can attract new investment without causing stock prices to fall.
A Treasury's promised payments are fixed in dollars. Its price can still fall if you sell before maturity. Inflation can also reduce what those dollars buy. If you reinvest the interest payments, the rates you earn on that money will affect your total return.
A bond fund is different from a single Treasury held to maturity. It has no single date when you are promised your original investment back.
There is a second connection to stocks: discounting. At a 3% annual discount rate, $100 received in ten years is worth about $74 today. At 5.29%, it is worth about $60. Those are illustrations, not full stock valuations: uncertain company cash flows require a risk premium as well. Holding other assumptions constant, higher required returns weigh especially heavily on businesses whose cash flows lie far in the future.
Why Institutions Might Buy More Bonds
Different investors face different constraints. Higher yields can change the tradeoffs without forcing everyone to make the same move.
- Pension funds and insurers can use bonds with suitable payment dates to help match future obligations. Higher yields may reduce the cost of securing those cash flows, although funding needs and liability timing still matter.
- Endowments weigh current income against long-term spending and growth needs. A higher nominal bond yield doesn't by itself establish that a portfolio can meet those needs after inflation.
- Balanced and target-date funds may rebalance toward bonds if market movements push their allocations away from their targets. That depends on their policies and existing holdings.
There is evidence of demand for the ETF structure. VettaFi reported that bond ETFs attracted $446 billion through September 11, exceeding 2025's full-year $439 billion (Advisor Perspectives, September 15). But that doesn't tell us how much came from selling stocks. The same report describes money moving from traditional mutual funds into bond ETFs, including very short-term products.
Profits can also grow enough to support stock prices despite higher yields. TaeHyung Kwon explored that tension in why stocks keep hitting records while the Fed debates a hike. Bond yields are one influence on valuations, not a complete explanation of where markets go next.
What to Watch Next
Both the level of yields and the speed of a move matter. A sudden jump gives borrowers and investors less time to adjust. There is no established yield threshold at which stocks or mortgages must break.
- Daily Treasury readings and intraday moves. Keep the date and measurement consistent. A brief high and a daily benchmark observation answer different questions.
- The Fed and inflation. The Fed raised its target range to 3.75–4.00% on September 16 (FOMC statement). New inflation and employment data can change expectations for its next decision and the path of longer-term yields.
- Treasury auctions. Demand for new debt helps show what yields buyers require. One auction provides a useful observation, not a lasting verdict on the market.
- The mortgage spread. If it widens, mortgage rates could rise even with stable Treasury yields. If it narrows, borrowers could get some relief without a Treasury rally.
Frequently Asked Questions
Does the Federal Reserve set mortgage rates?
Not directly. The Fed sets a target range for an overnight interest rate. Mortgage pricing depends on longer-term market yields, mortgage-security pricing, lender costs and borrower characteristics. Fed decisions influence those conditions, but mortgage rates don't move one-for-one with the policy rate.
Why do mortgage rates follow the 10-year Treasury rather than the 30-year?
Mortgage principal is repaid gradually, and homeowners may sell or refinance before the full term ends. That makes the 10-year Treasury a useful benchmark for a loan with a shorter effective life than its stated 30 years. The match is approximate and changes with repayment behavior and interest rates.
Will mortgage rates come down soon?
Lower Treasury yields or a narrower mortgage spread could bring rates down. The spread has already fallen substantially from its 2023 average, but its historical average isn't a floor. The data explain the sources of today's rate; they don't establish when either component will fall.
What Higher Yields Mean for You
- For home buyers, the Treasury benchmark matters. In the year-over-year comparison here, its increase outweighed a modest decline in the mortgage spread.
- For household budgets, small rate changes add up. A $400,000 loan costs about $251 more per month at Freddie Mac's October 1 rate than at its year-earlier rate.
- For investors, bonds offer stronger competition. Their yields are close to the S&P 500's forward earnings yield, but that comparison alone doesn't establish which asset will deliver the better total return.
When you see a headline about Treasury yields, read it as information about both borrowing costs and investment choices. If you're weighing the stock side of that decision, our framework for judging whether today's stock prices are a bubble or an opportunity is a good next read.
