A 10-year U.S. Treasury note is federal debt that pays fixed interest every six months for ten years, then repays its principal. Its yield is closely watched because it helps shape borrowing and investment conditions across the economy—but it does not set mortgage rates or other loan rates by itself.
What is a 10-year Treasury note?
A Treasury note is a marketable U.S. government security with a maturity of 2, 3, 5, 7, or 10 years. The 10-year note has a fixed interest rate set at auction, pays interest twice a year, and returns its face value at maturity if held to that date. See TreasuryDirect’s Treasury Notes page and its glossary.
For a $1,000 face-value note, the annual coupon is the fixed rate multiplied by $1,000, paid in two installments. Over ten years, that means 20 semiannual interest payments, followed by repayment of the $1,000 principal. Treasury notes are issued electronically. TreasuryDirect lists a $100 minimum purchase in $100 increments. New 10-year notes generally auction in February, May, August, and November, with reopenings during the year; the actual offering calendar can change. Consult the TreasuryDirect note page for current details.
Interest earned is subject to federal tax each year, according to TreasuryDirect. This article does not address state or local tax treatment.

What is the difference between the coupon rate and yield?
The coupon rate is fixed at auction and determines the note’s scheduled interest payments based on its face value. Yield to maturity is an annualized return measure that accounts for the price paid as well as the coupon payments and principal due, assuming the note is held to maturity and payments are made as scheduled.
After auction, the note can trade in the secondary market. Its price and yield move in opposite directions: if investors demand a yield above the coupon, the note generally sells below face value; if the demanded yield is below the coupon, it generally sells above face value. TreasuryDirect explains the relationship in Understanding Pricing and Interest Rates.

Selling before maturity means accepting the market price at the time, which can produce a gain or loss relative to what you paid. Holding to maturity returns face value, but does not eliminate inflation risk or the opportunity cost of having money committed while market rates change.
Why is the 10-year Treasury yield important?
The 10-year yield is one point on the Treasury yield curve, which relates yields to the time remaining until securities mature. The curve is used to price fixed-income securities and watched for clues about market expectations for future interest rates and the economic outlook. Federal Reserve staff models separate Treasury yields into expected future short-term rates and a term-premium component. The Fed’s Yield Curve Models and Data page describes these uses and components.
Treasury’s published par yield curve is derived from market bid prices for recently auctioned securities, including the latest 10-year note. A published par or constant-maturity yield is a curve estimate for a maturity point; it is not necessarily the coupon rate or the realized yield of a particular note held by an individual investor. The Treasury explains its approach in Treasury Yield Curve Methodology and publishes rates through Interest Rate Statistics.
Longer-term Treasury yields help inform the cost of credit for households and businesses and the pricing of other financial assets. In a February 12, 2026 Federal Reserve Board note, Daniel Covitz and Eric Engstrom wrote that “higher forward rates mean higher long-term Treasury yields, which boosts the current cost of long-term credit to households and businesses.” They also reported that, over the past 50 years, a simple regression on changes in the 9-to-10-year forward rate explained more than 80 percent of the variation in annual changes in the 10-year Treasury yield. That is a historical statistical relationship, not a forecast or proof that one rate mechanically causes the other. Read the note at FEDS Notes.
Rank #4
The yield is influential, not an official ranking of the “most important” rate and not a universal price-setting formula. Its significance comes from its role as a widely used benchmark and from its connection to longer-term financing conditions.
How does the 10-year Treasury yield affect mortgage rates?
The 10-year yield can influence mortgage pricing, but a household’s mortgage rate does not simply equal that yield. Mortgage lenders price loans in relation to funding markets and mortgage-backed securities (MBS), among other costs and risks. MBS yields and their spread relative to Treasury yields are part of the relationship: the Federal Reserve’s July 2026 Monetary Policy Report describes agency MBS yields as an important factor in home mortgage rates and compares them with the average of five- and ten-year Treasury yields.

Mortgage rates can therefore move differently from the 10-year yield or by a different amount. MBS spreads, lender margins, credit conditions, and loan features also matter. Treat the Treasury yield as a market reference that can affect mortgage conditions, not as a rate that directly determines each borrower’s quote.

Individuals can buy a note at auction or in the secondary market. TreasuryDirect accepts noncompetitive bids: you agree to the auction’s determined terms rather than specifying the yield you want. Brokers, dealers, and financial institutions can also provide access, including to securities trading after issuance. TreasuryDirect outlines the routes in its FAQs about Treasury Marketable Securities.
- Choose the route. Use TreasuryDirect for an eligible auction purchase, or contact a broker, dealer, or financial institution about auction or secondary-market access.
- Check the offering or listing. Review the maturity, auction information or market price, and available terms. For an auction bid through TreasuryDirect, select a noncompetitive bid if you do not want to state a yield.
- Choose the amount. TreasuryDirect lists a $100 minimum and purchases in $100 increments for notes. Intermediaries may have their own procedures or terms.
- Consider whether you may need to sell early. The secondary-market price can be above or below face value, so a sale before maturity can return more or less than your purchase price.
How does a nominal 10-year note compare with 10-year TIPS?
A nominal Treasury note has fixed principal. Treasury Inflation-Protected Securities (TIPS) adjust principal with inflation and deflation; because interest is calculated on adjusted principal, the dollar interest payment can vary. TreasuryDirect explains the distinction in Understanding Pricing and Interest Rates and its TIPS information.
| Feature | Nominal 10-year note | 10-year TIPS |
|---|---|---|
| Principal | Fixed face value; repaid at maturity if held to maturity. | Adjusted for inflation and deflation. |
| Interest payments | Fixed rate applied to face value; paid every six months. | Rate applies to adjusted principal, so the dollar payment can vary. |
| Inflation treatment | Principal is not inflation-adjusted. | Principal adjusts with inflation and deflation. |
| Early sale | Market price may be above or below face value. | Market price may also change; price risk remains if sold before maturity. |
When comparing the two, consider inflation protection, the type of yield being quoted, cash-flow needs, maturity, and whether you might sell before maturity. The nominal 10-year yield alone is not a forecast of inflation and does not make TIPS the right choice for every investor.
