Two headlines from the same week seem to contradict each other: the 10-year Treasury yield just posted its highest close since July 2007, and the Nasdaq Composite is sitting within a fraction of a percent of an all-time record. Both are true, because rising yields have not broken the stock market as a whole. They have mainly left behind the Russell 2000 and the Dow Jones Industrial Average, while a narrow group of large, AI-linked companies keeps major indexes near their records. Here is what is driving Treasury yields higher, why that narrow group of stocks hasn't cracked, and what it all means for mortgages, savings and portfolios, as of Friday's close (September 25, 2026).
Key Takeaways
- The 10-year Treasury yield closed at 5.18% on Thursday, September 24, 2026, its highest close since July 2007, and at 5.17% on Friday; the 30-year closed at 5.49% on Friday, its highest since 2004.
- The Nasdaq Composite and S&P 500 are both within about 1% of their all-time record closes, but the Russell 2000 (small-company stocks) is 7.52% below its August high and down 6.18% since June 30.
- Three explanations for the higher yields are all plausible: inflation and the Federal Reserve's September rate increase, stronger growth, and rising government deficits and debt issuance. None can be confirmed as the sole cause.
- The average 30-year fixed mortgage rate rose to 7.03% for the week of September 24, and the University of Michigan consumer sentiment index fell to a four-month low of 48.1 in September.
- Past performance does not guarantee future results, and the current divergence between bond yields and large-cap stocks can resolve in more than one direction.
Yields and Indexes as of Friday's Close
A Treasury yield is the annual return an investor earns by holding a U.S. government bond to maturity; it moves opposite to the bond's price, because a fixed interest payment becomes more or less attractive to buyers as price changes. Yields are typically measured in basis points, where one basis point equals one-hundredth of a percentage point. A move from 5.01% to 5.17% is a rise of 16 basis points.
The table below shows where the major Treasury yields and stock indexes stood at Friday's close, alongside how much each has moved since June 30, 2026, and since the Federal Reserve's September 16 interest-rate increase.
| Instrument | Sep 25 close | Change since Jun 30 | Change since Sep 16 hike |
|---|---|---|---|
| 10-year Treasury yield | 5.17% | +73 bp | +16 bp |
| 30-year Treasury yield | 5.49% | +58 bp | +14 bp |
| 2-year Treasury yield | 4.81% | +67 bp | +7 bp |
| 3-month Treasury bill | 4.24% | +37 bp | +10 bp |
| S&P 500 | 7,743.41 | ▲ +3.25% | ▲ +2.54% |
| Nasdaq Composite | 27,068.72 | ▲ +3.26% | ▲ +4.20% |
| Dow Jones Industrial Average | 51,828.62 | ▼ −0.94% | ▲ +0.71% |
| Russell 2000 | 2,837.55 | ▼ −6.18% | ▼ −0.74% |
The pattern in that table is this article's central point: every Treasury yield has risen, but the four stock indexes have not moved together. The S&P 500 and Nasdaq Composite are higher across both windows; the Dow is roughly flat to slightly lower; and the Russell 2000, an index of smaller U.S. companies, has fallen in both windows and is down more than 6% since June 30. The 10-year yield's previous high this decade was 4.98% in October 2023, before it eased over the following two years, a reminder that yield cycles have historically moved in both directions.
Longer-dated yields have also risen faster than short-dated ones, a pattern called yield-curve steepening. The yield curve plots yields across different maturities, from short-term bills to 30-year bonds. The gap between the 10-year and 2-year yields widened from 30 basis points on June 30 to 36 basis points on September 25; the gap between the 10-year and 3-month bill widened from 57 to 93 basis points. A curve where long rates rise faster than short rates is one sign, though not proof, that investors are demanding more compensation for holding longer-term debt, a theme covered below.
Why Are Treasury Yields Rising? Three Explanations, No Winner
No single, confirmed cause explains why yields have risen this much. Economists and market strategists point to three overlapping explanations: inflation and the Federal Reserve's policy reversal, stronger economic growth, and a rising term premium tied to government borrowing. Each has supporting evidence and each has a counter-argument, and nothing in the available data settles which one dominates.
Inflation and a Fed Reversing Course
On September 16, 2026, the Federal Reserve's rate-setting committee raised the federal funds rate (the short-term interest rate the Fed sets, which influences borrowing costs throughout the economy) by 25 basis points to a range of 3.75% to 4.00%, effective September 17, its first increase since July 2023. Fed Chair Kevin Warsh said at the press conference, "Inflation is too high and has been for too long."
What supports this: the Fed cited persistent inflation as its reason for hiking, and consumers have grown more worried about future prices. The University of Michigan's survey shows year-ahead inflation expectations rising to 4.6% in September from 4.0% in August.
What argues against it: the most recent Consumer Price Index report, for August 2026, showed core inflation (excluding food and energy) cooling to 2.4% year-over-year from 2.5% the month before, even as headline inflation held at 3.4%. The Fed's preferred gauge, the Personal Consumption Expenditures price index, last stood at 3.3% core for July 2026, a reading from before the sharpest part of the September yield move; the August figure is due September 30. Warsh also pointed to higher fuel prices as a contributor to inflation, without tying the broader yield move to that factor specifically.
Stronger Growth and Rising Real Yields
A second explanation is that yields are rising because the economy is doing better than expected, pushing up real yields, the return investors demand after accounting for inflation. What supports this: the August 2026 jobs report showed employers added 162,000 jobs and unemployment held at 4.1%. Treasury Secretary Scott Bessent has argued the government "can grow its way out of the debt" if growth reaches 3%. What argues against it: the second estimate of second-quarter 2026 GDP showed a comparatively modest 1.5% annualized pace, and the Fed's statement described current activity as "expanding at a solid pace," a moderate characterization, not one suggesting an overheating economy. A third GDP estimate is due September 30.
Deficits, Issuance and a Rising Term Premium
The third explanation centers on the federal government's borrowing needs. The term premium is the extra yield investors require to hold a longer-dated bond instead of rolling over a series of shorter-dated ones, compensating for the added risk of tying up money for longer. What supports this: the Congressional Budget Office's most recent full-year deficit estimate for fiscal year 2026 is roughly $2 trillion, above its earlier projection, and some bond strategists have pointed to heavy debt issuance and deficit concerns as contributors to higher long-term yields. The curve steepening described above (long yields rising faster than short ones) is consistent with a rising term premium, though it does not prove one exists at any specific size. What argues against it: the same period also included a Fed rate increase and stronger jobs data, either of which could independently push yields higher without any change in how investors price long-term borrowing risk.
None of these three explanations rules out the others, and yields may be responding to a combination of all three at once.
Why Stocks Haven't Cracked, and Why It's a Narrow Group
Why are stocks still near record highs if bond yields are this high? The short answer from the table above is that "stocks" is doing a lot of work in that question. The Nasdaq Composite and S&P 500 (both heavily weighted toward a handful of large technology and AI-related companies) are near their records. The Russell 2000 and, to a lesser degree, the Dow are not.
On September 21 and 22, 2026, a rally in chipmaking companies, including Intel, Advanced Micro Devices and Qualcomm, helped push the Nasdaq Composite to back-to-back record closes, ending at 27,244.28 on September 22. As of Friday's close, the Nasdaq sits 0.64% below that record, and the S&P 500 sits 0.71% below its own August 13 record of 7,798.99. The Dow, by contrast, sits 4.64% below its own record of 54,349.12 set August 5.
Goldman Sachs has said market breadth (the share of stocks participating in a rally, rather than a handful of large names driving the index higher) has narrowed to one of its thinnest levels since the dot-com era, consistent with an index-level record that does not reflect the broader market.
Company size also affects how directly a business feels rising yields. Larger, cash-rich companies often carry more fixed-rate, longer-term debt and rely less on frequent refinancing, so a jump in borrowing costs affects their finances more slowly. Many smaller companies carry more floating-rate or shorter-term debt and hold less cash on hand, so higher borrowing costs show up more quickly. That difference in balance-sheet composition, not a claim about any specific company, is one general reason smaller companies, represented in the Russell 2000, are often described as more sensitive to rising rates than the largest companies in the S&P 500 and Nasdaq.
What Rising Yields Mean for Stock Valuations
Rising Treasury yields affect how investors value stocks through a concept called the discount rate: the rate used to translate a company's expected future profits into a value expressed in today's dollars. When that rate rises, the same stream of future profits is worth less today, all else being equal.
One way analysts compare stocks with bonds is through the earnings yield: a company's or index's annual earnings divided by its share price, the mathematical inverse of the more familiar price-to-earnings ratio. The gap between a stock market's earnings yield and the 10-year Treasury yield is sometimes called the equity risk premium: the extra return investors require for taking on stock-market risk instead of holding a government bond. As a purely illustrative, hypothetical example, not a current market figure, a stock market priced at 20 times earnings has an earnings yield of 5%; if the 10-year Treasury yield also sits near 5%, that hypothetical gap would be close to zero: little extra expected return for taking on stock-market risk instead of a government bond. For a fuller explanation, see our guide to how Fed policy feeds into stock valuations.
None of this implies today's market is overvalued or undervalued; the mechanism above describes how the math works, not a verdict on current prices. Higher yields raise the bar that expected earnings growth has to clear to justify a given valuation, one reason a narrow group of companies with strong earnings expectations can keep climbing even as the broader, more rate-sensitive market lags, as shown above. Past valuation cycles have unwound in different ways, and this divergence may resolve in more than one way too.
What It Means for Your Wallet: Mortgages, Savings and Sentiment
Rising Treasury yields reach well beyond Wall Street. They influence what households pay to borrow, what savers earn, and (the data below suggests) how people feel about the economy overall. For a broader look at how these mechanics work in general, see our guide to how interest rates ripple through borrowing and saving.
| Measure | Latest | Prior |
|---|---|---|
| 30-year fixed mortgage rate (average) | 7.03% (week of Sep 24) | 6.95% (Sep 17); 6.76% (Sep 10) |
| 3-month Treasury bill yield | 4.24% (Sep 25) | 3.87% (Jun 30) |
| Consumer sentiment index (University of Michigan, September final) | 48.1 | 51.7 (August) |
| Year-ahead inflation expectations | 4.6% | 4.0% |
| Long-run inflation expectations | 3.4% | 3.3% (the three prior months) |
Mortgage Rates
The average 30-year fixed mortgage rate has climbed for five straight weeks, including the three readings shown above. Mortgage rates generally track the 10-year Treasury yield, though not exactly, since lenders also price in their own costs and risks on top of the underlying government-bond benchmark.
Savings, Money-Market and T-Bill Yields
The rise in yields is not one-directional for households. The 3-month Treasury bill, a short-term government security often used as a benchmark for savings and money-market yields, has climbed alongside longer-dated yields, as shown above. Savers holding cash in yield-bearing accounts have, in general, benefited from higher short-term rates over the past several years, even as borrowers have faced higher costs on new loans.
Consumer Sentiment
The University of Michigan consumer sentiment index fell to a four-month low in September, as shown above, while both year-ahead and longer-run inflation expectations ticked higher. Consumer sentiment is one gauge of household mood, not a direct measure of spending or the broader economy, but a falling reading alongside rising borrowing costs and inflation expectations describes a real strain many households are feeling this fall.
The Week Ahead: The Data That Tests This Story
Several scheduled economic reports over the coming week could add evidence for or against each of the three explanations above. Each row notes what a stronger or weaker result would be consistent with, not what is expected.
| Date | Release | Why it matters for yields |
|---|---|---|
| Mon, Sep 28 | Treasury bill auctions | Weak demand would fit concerns about debt absorption; strong demand would argue against it. |
| Tue, Sep 29 | JOLTS job openings (August) | A stronger reading fits the growth explanation; a weaker one argues against it. |
| Tue, Sep 29 | Conference Board consumer confidence (September) | A further decline, echoing the weak University of Michigan reading, fits the strain on households; a rebound argues the opposite. |
| Wed, Sep 30 | Q2 GDP, third estimate | An upward revision from 1.5% fits the growth explanation; a downward one argues against it. |
| Wed, Sep 30 | PCE price index (August) | A hotter core reading fits the inflation explanation; a cooler one argues against it. |
| Thu, Oct 1 | ISM Manufacturing PMI (September) | A reading further into expansion fits the growth explanation; a move toward contraction argues against it. |
| Thu, Oct 1 | Weekly jobless claims | A notable rise argues against the growth explanation; a further decline fits it. |
| Fri, Oct 2 | September jobs report | A payrolls surprise above August's pace fits the growth explanation; a weak report argues against it. |
Two-year, five-year and seven-year Treasury note auctions are also scheduled during the week, though the exact day for each has not been confirmed.
Frequently Asked Questions
Why are Treasury yields rising?
No single factor fully explains it. Three overlapping explanations each have supporting evidence: persistent inflation and the Fed's September rate increase, stronger growth, and rising government deficits and debt issuance. None can be confirmed as the dominant cause.
Why do bond prices fall when yields rise?
A bond pays a fixed interest amount. When newly issued bonds offer a higher rate, existing bonds with lower fixed payments become less attractive at their original price, so their market price falls until their effective yield matches prevailing rates. Price and yield move in opposite directions by definition.
Why are stocks still near record highs if bond yields are high?
Because "stocks" is not one thing. The Nasdaq Composite and S&P 500, both weighted toward a small number of large, AI-linked companies, are within about 1% of their all-time record closes. The Russell 2000, representing smaller companies, is more than 7% below its August high, and the Dow is also below its summer peak.
Is a rising 10-year Treasury yield bad for stocks?
It depends on why yields are rising. An increase driven mainly by stronger growth can coincide with rising earnings, which can offset a higher discount rate. An increase driven mainly by inflation or fiscal worries, without matching earnings growth, would be a tougher backdrop for valuations. Both dynamics can be present at once, as the three explanations above show.
How does the 10-year Treasury yield affect mortgage rates?
Mortgage lenders use the 10-year Treasury yield as one benchmark when pricing long-term, fixed-rate mortgages, then add their own costs and risk margins on top. The two don't move in lockstep, but they generally trend together, one reason the average 30-year fixed mortgage rate has risen alongside the 10-year yield in recent weeks.
Does the Federal Reserve control the 10-year Treasury yield?
Not directly. The Fed sets the federal funds rate, a short-term rate, which influences yields across the curve. Longer-term yields like the 10-year are set by the broader market, based on expectations for growth, inflation and government borrowing, which is why the 10-year yield kept rising even after the September 16, 2026 hike.
The Bottom Line
Two things are true as of Friday's close: Treasury yields have climbed to levels not seen in nearly two decades, and a narrow group of large stocks has kept major indexes near their records. Neither fact cancels out the other, and the gap between them can close in more than one way: through earnings growth catching up with higher yields, through yields easing, or through the divergence simply persisting. The data due out over the coming week, from the jobs report to the Fed's preferred inflation gauge, will add evidence one way or another, without settling the question on its own.
