Treasury yields are the annualized rates of return investors earn for lending money to the U.S. federal government by holding its debt securities. As of early 2026, the 10-year Treasury yield sits near 4.22% and the 30-year around 4.85%, benchmarks that ripple through mortgage rates, corporate borrowing costs, and savings account returns across the economy.1U.S. Department of the Treasury. Daily Treasury Par Yield Curve Rates The yield itself is set by the price buyers and sellers settle on in the open market, which is why it moves every trading day even though the underlying bond’s interest payments are fixed.
Yield vs. Coupon vs. Basis Points
A Treasury’s coupon rate is the fixed interest payment locked in when the bond is first issued. It never changes. The yield is what you actually earn based on the price you paid, and it shifts constantly with market prices.
Buy a bond at face value (called “par”), and the yield and coupon rate match. Pay less than par and your yield rises above the coupon, because you’re collecting the same fixed payments on a smaller investment. Pay more than par and the yield drops below the coupon. Yields are quoted as annual percentages so you can compare them against savings accounts, CDs, corporate bonds, or any other investment.
Yield movements are measured in basis points. One basis point equals one-hundredth of a percentage point (0.01%). A headline saying the 10-year “jumped 15 basis points” means it rose 0.15 percentage points. The unit exists because bond markets routinely move in fractions of a percent where saying “a quarter of a percent” gets ambiguous fast.
Why Prices and Yields Move in Opposite Directions
Treasury securities trade actively on the secondary market after their initial auction. Since 1986, they’ve existed only as electronic records rather than paper certificates, making them easy to buy and sell through financial institutions.2Treasury Office of Inspector General. How Marketable Treasury Securities Work The price fluctuates throughout each trading day based on demand, economic news, and interest rate expectations.
The inverse relationship between price and yield is the single most important concept in the bond market. Consider a Treasury note with a $1,000 face value and a $30 annual coupon payment (a 3% coupon rate). If demand drops and the market price falls to $950, a new buyer still collects that $30 per year plus a $50 gain at maturity. The yield is now higher than 3%, because the buyer’s total return is measured against the $950 they actually invested. If demand surges and the price climbs to $1,050, the math flips: the buyer earns the same $30 but paid a premium, so the yield falls below 3%.
This is what keeps older bonds competitive with newly issued ones. When the Treasury starts auctioning new notes at 4%, existing bonds with 3% coupons have to drop in price until their effective yield reaches something close to 4%. Otherwise, nobody would buy them. The adjustment happens automatically as traders bid prices up or down.
Duration measures how sensitive a bond’s price is to those yield changes. A bond with a duration of 10 years would lose roughly 10% of its value if yields rose by one percentage point; a two-year bond would lose only about 2%. That’s why long-dated Treasuries can swing dramatically in price even though they carry no credit risk. If you need to sell before maturity, longer bonds carry real price risk.
What Drives Yields Up and Down
Federal Reserve Policy
The Federal Reserve’s primary lever is the federal funds rate, the interest rate banks charge each other for overnight loans. Changes in this rate cascade through the rest of the financial system.3Board of Governors of the Federal Reserve System. How Does the Federal Reserve Affect Inflation and Employment? When the Fed raises its target rate, short-term Treasury yields almost always follow, because investors can earn more in overnight bank deposits and money market funds and will demand comparable returns from short-term government debt.
Longer-term yields respond too, but less directly. A 10-year yield reflects not just where the federal funds rate is today but where investors expect it to be over the next decade.4Federal Reserve. The Fed Explained – Monetary Policy If the market believes rate hikes are temporary, long-term yields may barely budge even as short-term yields spike.
Inflation Expectations
Inflation is a bond investor’s biggest enemy. Lock in a 4% yield for 10 years with inflation running at 3.5%, and your real return is only about 0.5%. Investors therefore demand higher nominal yields when they expect prices to rise faster, and accept lower yields when they believe inflation is cooling.
The gap between a standard Treasury yield and a Treasury Inflation-Protected Securities (TIPS) yield of the same maturity is called the breakeven inflation rate. It represents the market’s collective bet on average inflation over that period.5Federal Reserve Bank of St. Louis. 10-Year Breakeven Inflation Rate (T10YIE) If the 10-year Treasury yields 4.2% and the 10-year TIPS yields 1.8%, the breakeven rate is roughly 2.4%, meaning investors expect inflation to average about 2.4% annually over that decade.
Flight to Safety
During periods of global instability, investors flee stocks and riskier assets for U.S. government debt. The surge in demand pushes bond prices up and yields down, sometimes sharply. The pattern is reliable enough that experienced traders watch Treasury yields as a real-time gauge of market fear. When yields plunge on a Tuesday morning, something has spooked the market, even if the headlines haven’t caught up yet.
The Securities That Produce These Yields
The Treasury Department finances government spending by issuing marketable securities through regular auctions.6U.S. Department of the Treasury. Financing the Government Each type covers a different slice of the maturity spectrum, and each produces a yield that sits somewhere on the curve.
Treasury bills mature in 4 to 52 weeks and don’t pay periodic interest. They’re sold at a discount from face value, and the difference between what you paid and what you receive at maturity is your return.7TreasuryDirect. When Auctions Happen (Schedules)
Treasury notes cover 2, 3, 5, 7, and 10-year terms and pay a fixed coupon semiannually.8TreasuryDirect. About Treasury Marketable Securities The 10-year note gets the most attention because its yield serves as the benchmark for mortgage rates and many corporate bonds.
Treasury bonds are the longest-dated issues, offered in 20 and 30-year terms, and also pay semiannual interest.8TreasuryDirect. About Treasury Marketable Securities Because so much can change over two or three decades, these typically carry the highest yields on the curve and the most price sensitivity to rate moves.
TIPS protect against inflation. The principal adjusts with the Consumer Price Index, and the semiannual interest is calculated on the adjusted amount. At maturity you receive either the adjusted principal or the original face value, whichever is greater.9TreasuryDirect. Treasury Inflation-Protected Securities (TIPS) TIPS come in 5, 10, and 30-year terms.
Floating Rate Notes are the only Treasuries with a variable interest rate. The rate combines an index tied to the most recent 13-week T-bill auction with a fixed spread set at issuance, and because the index resets weekly, your payments move with short-term rates.10TreasuryDirect. Floating Rate Notes (FRNs) FRNs mature in two years.
STRIPS (Separate Trading of Registered Interest and Principal of Securities) split a note or bond into its individual interest and principal payments, each sold as a separate zero-coupon security.11TreasuryDirect. STRIPS You buy each piece at a discount and receive its face value at maturity. T-bills and FRNs cannot be stripped.
Reading the Yield Curve
The yield curve plots Treasury yields across all maturities on a single chart. The Treasury Department publishes these daily as “Constant Maturity Treasury” (CMT) rates, derived from bid-side market prices collected each trading day.1U.S. Department of the Treasury. Daily Treasury Par Yield Curve Rates The shape tells you what the bond market collectively expects about the future.
A Normal, Upward-Sloping Curve
In a healthy, growing economy, short-term yields sit below long-term yields. Investors demand extra compensation for tying money up for 10 or 30 years because more can go wrong over a longer horizon. The steeper the upward slope, the more optimistic the market is about future growth.
An Inverted Curve
An inversion happens when short-term yields exceed long-term yields. The spread most commonly watched is the gap between the 10-year and 2-year Treasuries. When it turns negative, investors are signaling that they expect the economy to weaken and the Fed to cut rates later, which is why they’ll accept lower long-term returns now.
Historically, the yield curve has inverted before each of the last seven recessions. Three caveats limit it as a crystal ball: the lag between inversion and recession varies widely, the curve has occasionally inverted without a recession following, and the predictive power may be weaker now than in past decades because a persistently low “term premium” (the extra yield investors demand for holding longer-dated debt) makes the curve naturally flatter and more prone to brief inversions.12Congressional Research Service. The Yield Curve and Predicting Recessions An inversion is worth watching, but treating it as an automatic recession alarm has misled investors before.
A Flat Curve
When short- and long-term yields sit near each other, the curve is flat. It typically appears during transitions, either when the market is uncertain which direction the economy is heading, or when the Fed is pushing short-term rates up toward long-term levels mid-tightening. Flat curves often precede either a return to normal steepness or a full inversion.
Why Treasury Yields Matter If You Never Buy a Bond
You don’t need to own a Treasury for its yield to affect you. The 10-year yield in particular acts as the benchmark that mortgage lenders, corporate borrowers, and banks use to price their own debt. When the 10-year rises, fixed mortgage rates generally rise with it. When it falls, borrowing gets cheaper across the economy. Savings account rates and CD yields track short-term Treasuries more closely, which is why bank deposit rates tend to climb only after the Fed raises its target and short-term Treasury yields follow.
Watching how yields move, and how the curve is shaped, gives you a running read on what the bond market thinks is coming next for inflation, growth, and Fed policy. That read isn’t always right. But it’s the single most-watched signal in finance, and understanding what it’s saying puts you ahead of most headlines about it.
