The connection runs through bond prices, expectations for future interest rates, and the extra risk premiums investors demand. For borrowers, the practical result depends on the loan, its benchmark, and whether the rate is fixed or adjustable.
What a Treasury yield measures—and why bond prices move the other way
A Treasury yield is the return implied by the market price of a Treasury security. Treasury notes and bonds promise principal repayment and periodic interest, but their market prices change. For an existing fixed-payment bond, a lower market price means a higher yield; a higher price means a lower yield. The coupon is the bond’s stated interest payment, not its current market yield. The Federal Reserve explains the price-yield relationship and how it estimates the nominal Treasury yield curve from coupon securities in its nominal yield curve materials.
The yield curve displays yields across different maturities. It helps price fixed-income securities and is watched for what it may signal about future policy rates and the economic outlook. A 2-year Treasury yield and a 10-year Treasury yield can therefore move differently: each reflects market pricing over a different horizon.
Why Treasury yields rise
A Treasury yield can rise because investors expect higher short-term interest rates in the future, because they demand more compensation for risk, or both. Federal Reserve Governor Philip Jefferson described intermediate- and long-term rates as reflecting expected future short rates and discussed the role of risk premiums in his March 27, 2023 speech.

That is why neither the federal funds rate nor any single policy decision mechanically determines the 10-year Treasury yield. Markets continually revise their expectations, and the yield also reflects compensation investors require for holding longer-term securities. A change in Treasury yields can then influence other rates, but it does not set every consumer or business loan rate by itself.
How Treasury yields connect to mortgage rates
Mortgage rates are linked to Treasury yields through fixed-income markets, especially agency mortgage-backed securities (MBS). The Federal Reserve identifies agency MBS yields as an important factor in setting home mortgage rates. Its 2014 study of mortgage rates and agency MBS yields documented high comovement between 30-year fixed mortgage rates and 30-year current-coupon agency MBS yields in the historical sample it examined. That historical relationship illustrates a transmission channel; it is not a promise of a fixed or one-for-one change in mortgage rates whenever Treasury yields move.
Rank #2
The difference between an MBS yield and a comparable Treasury yield—the MBS-Treasury spread—can change. Mortgage pricing also reflects factors such as interest-rate volatility and prepayment risk, as well as lender pricing and loan terms. The Federal Reserve discusses these market dynamics in its June 2025 Financial Stability Report. As a result, mortgage rates may rise less or more than a Treasury benchmark, or move differently over a given period.
What higher Treasury yields mean for other borrowing costs
Comparable-maturity Treasury yields commonly serve as benchmarks for corporate and municipal borrowing. A borrower’s all-in yield also includes a spread: the additional return investors demand for credit risk and other market risks. That spread can widen or narrow independently of Treasury yields. If Treasury yields rise while a borrower’s spread narrows, its borrowing cost may rise by less; if the spread widens, the cost may rise by more. Federal Reserve reporting shows that yields and spreads can move differently across corporate, municipal, and MBS markets.
The same broad transmission applies to households and businesses, but timing varies. Federal Reserve Governor Jefferson put the effect this way: “Higher long-term interest rates increase the cost of borrowing money for households and businesses.” The quote comes from his March 27, 2023 speech. Higher market rates can affect the cost of new borrowing and influence financial decisions, but they do not automatically reprice every existing fixed-rate loan.
Fixed-rate borrowers and new applicants face different conditions
For a borrower with an existing fixed-rate mortgage, the contracted interest rate generally does not change just because Treasury yields rise. New applicants and people refinancing are exposed to current mortgage pricing; adjustable-rate borrowers may face changes according to their loan’s terms and reset schedule. Existing low-rate borrowers may also be less inclined to move or refinance, which can shape housing decisions.
The Federal Reserve’s July 2026 Monetary Policy Report described most outstanding mortgages as having rates below 4 percent, while citing a prevailing 30-year fixed mortgage rate of 6.4 percent. The mortgage series cited in that report covers contract rates on 30-year fixed-rate conventional home mortgage commitments through July 1, 2026. These are dated U.S. observations, not live quotes or a forecast.

The same Federal Reserve report said that, net, 2-year Treasury yields had risen about 60 basis points and 10-year yields about 35 basis points since the beginning of 2026. Those figures describe the period covered by the July 2026 report; they should not be read as current market quotations. The different moves also illustrate why it matters to compare rates with similar maturities rather than treating “Treasury yields” as one number.

A Treasury yield is a useful reference point, but it is not directly interchangeable with an advertised mortgage, corporate, or municipal rate. For a meaningful comparison:
Quick Recap
- Match the horizon. Compare rates with similar maturities; the Treasury yield curve varies across terms.
- Separate benchmark from spread. Identify the additional cost associated with credit and market risk rather than attributing the entire loan rate to Treasury movements.
- For mortgages, consider the MBS link. Agency MBS yields and their spreads to Treasuries help explain mortgage pricing, alongside lender pricing and the loan’s terms.
- Compare like borrowers and products. Distinguish fixed from adjustable rates, new loans from outstanding fixed-rate loans, and different corporate or municipal credit categories.
- Date the comparison. Market rates change over time. The July 2026 figures above are U.S. data tied to a specific report, with mortgage observations through July 1, 2026.
