The 10-year Treasury yield: why it matters and what drives it

If you follow only one interest rate, it is probably the yield on the 10-year Treasury note. It is the annual return the market demands to lend to the US government for a decade, and it moves every second the bond market is open. Financial news quotes it daily, mortgage lenders price off it, equity analysts build it into their discount rates, and central banks around the world watch it.

The 10-year earns that status for practical reasons. Ten years is long enough to reflect the market's view of inflation and growth well beyond the current business cycle, but short enough to trade in enormous volume. Treasury sells a new 10-year note four times a year and reopens it in the other months, so there is always a fresh, liquid benchmark.

This page covers what the 10-year yield measures, its history since 1953, how to split it into a real yield and expected inflation, why it can move against the Federal Reserve, and how it reaches mortgages and stock prices. The curve it sits on is explained in The yield curve: shapes, slopes and what each end tells you.

What the 10-year yield is

The "10-year yield" quoted in the news is the yield to maturity of the most recently issued 10-year Treasury note, or, in official statistics, Treasury's constant-maturity estimate of what a note with exactly 10 years left would yield. The two are almost identical. The monthly and daily series on this page are the Federal Reserve's H.15 constant-maturity versions.

Like any bond yield, it moves opposite to price: when buyers bid the note up, its yield falls, and when they sell, it rises (the mechanics are on Bond prices and yields: why prices fall when yields rise). It is quoted in percent, and traders talk about changes in basis points: a move from 5.05% to 5.10% is 5 basis points.

Seventy years in one chart

The history falls into three long phases.

• The climb, 1953–1981. The series starts at 2.83% in April 1953. Average yields rose every decade, from 3.24% in the 1950s to 4.67% in the 1960s and 7.50% in the 1970s, as inflation accelerated. The peak came in September 1981 at 15.32%.
• The forty-year descent, 1981–2020. As inflation came down and stayed lower, the 10-year fell in a long, bumpy decline: decade averages of 10.60% in the 1980s, 6.66% in the 1990s, 4.46% in the 2000s and 2.41% in the 2010s. It reached its low of 0.62% in July 2020; the daily low was 0.52% on 4 August 2020.
• The reversal, 2020–2026. The yield rose to year-end readings of 3.88% in 2022 and 2023, 4.58% in 2024 and 4.18% in 2025. In 2026 it ranged from 3.97% (27 February) to 5.31% (5 October), its highest daily reading since at least 2006, where our daily file begins. The September 2026 monthly average, 4.99%, was the highest since July 2007 (5.00%).

Across the whole 1953–2026 sample the monthly average was 5.52%. By that yardstick the ultra-low yields of the 2010s were the unusual period, not the yields of 2026.

What drives it: expectations, inflation and the term premium

You can think of the 10-year yield as the sum of three pieces:

1. Expected real short-term rates over the next decade, which depend on where investors think the Fed's policy rate will settle after adjusting for inflation, and ultimately on the economy's growth potential.
2. Expected inflation over the decade, because lenders want to be repaid in dollars that still buy something.
3. The term premium, the extra yield for bearing the risk of a 10-year commitment rather than rolling short-term bills.

The first two can be measured directly from the market. The third has to be estimated, which is why stories about why the 10-year moved often disagree.

Splitting the yield: real yield plus breakeven

The Treasury also sells TIPS, whose principal rises with the CPI. A 10-year TIPS yield is therefore a real yield, a return above inflation. The difference between the ordinary 10-year yield and the 10-year TIPS yield is the breakeven inflation rate: the average CPI inflation at which the two would pay the same.

The split tells you what kind of move the 10-year is making.

The striking line is the first against the last. On 3 August 2021 the TIPS real yield hit its lowest reading in the data, −1.19%, and the breakeven was 2.38%. On 28 October 2026 the breakeven was again 2.38%, while the real yield was 2.67%. The whole 3.86-point rise in the 10-year over those five years came through the real-yield component. In between, the breakeven peaked at 3.02% in April 2022, the highest in the series since it began in 2003, and drifted back. Higher nominal yields in this period meant higher real borrowing costs, not higher expected inflation: a distinction that matters for stocks, because real yields are what compete with real earnings. The theory behind real rates is on Real interest rates: nominal rates minus inflation, explained.

Why it can move against the Fed

The Federal Reserve sets an overnight rate, not the 10-year. Its decisions reach the 10-year only through expectations of future policy and through the term premium, so the two can diverge.

Policy and the long end did move the same way in 2026: the Fed raised its target range by 25 basis points, to 3.75–4.00%, effective 17 September, and the 10-year averaged 4.99% that month, up from 4.68% in August. But the 10-year had already climbed from 4.32% in April before any increase took effect. Episodes like these mean the long end is pricing something beyond the next meeting, whether that is inflation risk, the economy's strength or the term premium. The page How Fed decisions move markets: expectations, surprises and yields looks at how the 2-year, not the 10-year, tends to track policy expectations most closely.

How the 10-year reaches the real economy

Mortgages. A 30-year fixed-rate mortgage is usually repaid or refinanced well before 30 years, so lenders and mortgage-bond investors price it against Treasury yields of roughly 10-year maturity, plus a spread for credit, prepayment and servicing costs. Mortgage rates therefore tend to rise and fall with the 10-year, though the spread itself changes over time.

Corporate borrowing. Investment-grade companies issue bonds priced as a spread over Treasuries of similar maturity. A higher 10-year raises their borrowing costs one for one unless spreads narrow. See Credit ratings and credit spreads: how bond risk is priced.

Stock valuations. Valuation models discount future cash flows at a rate built from a risk-free yield plus an equity risk premium (see Discounted cash flow (DCF): a step-by-step valuation on Apple). A higher 10-year raises that discount rate and lowers the present value of distant profits, which hits long-duration growth stocks hardest. How interest rates affect stocks: discount rates and equity duration tests that idea against five years of market data.

The rest of the world. Many governments, companies and funds outside the US borrow, lend or invest in dollars, and the 10-year Treasury is their reference point too. A move in US yields often shows up in yields abroad and in the dollar's exchange rate.

Pitfalls and limitations

• Level versus change. A 5% 10-year is high compared with the 2010s and low compared with the 1980s. What usually moves markets is the change relative to expectations.
• The term premium is model-dependent. Explanations of a move that rely on it are estimates, not measurements.
• Breakeven is not a pure inflation forecast. It also reflects inflation-risk and liquidity premiums, which change over time.
• Different quotes, same thing. The on-the-run note's yield, the constant-maturity yield and the ^TNX index differ by small amounts and at different times of day. Use one consistently.
• Correlation is not causation. Stocks and the 10-year sometimes rise together, when stronger growth lifts both, and sometimes move apart. The link is real but not mechanical.

How Finabase does it

Finabase quotes the 10-year yield in several forms, though it has no real-yield, breakeven or term-premium data.

• US10Y=T, in the Treasury yields list with the other maturities from 1 month to 30 years, has a symbol page with a chart that can be set to any range.
• ^TNX, the 10-year yield index, sits in the Bonds group of the indices list next to ^FVX (5-year) and ^TYX (30-year).
• 10-year Treasury note futures are in the futures list; their price moves opposite to the yield.
• The Fed news topic gathers rate headlines.

The 70-year chart and the real-yield and breakeven decomposition on this page were built by Finabase Research from Federal Reserve data, not from an in-app feature.

Frequently asked questions

Why is the 10-year Treasury yield so important?

Because so much else is priced from it. Mortgage rates, corporate bond yields and the discount rates used to value stocks are all set relative to it, and it is the most liquid long-term benchmark in the world's largest bond market.

What makes the 10-year Treasury yield go up?

Higher expected inflation, higher expected policy rates over the decade, a higher term premium, or some combination. Splitting the yield into its TIPS real yield and breakeven inflation shows which: from August 2021 to October 2026 the entire 3.86-point rise came from the real-yield part.

Does the Fed set the 10-year yield?

No. The Fed sets the overnight federal funds rate; the 10-year is set by trading in the Treasury market. After the Fed began cutting in September 2024, the 10-year rose from 3.63% to 4.58% by the end of the year.

What is a normal 10-year Treasury yield?

There isn't one fixed level. Its monthly average since 1953 is about 5.5%, but it ranged from 15.32% in 1981 to 0.62% in 2020. The 2010s averaged 2.41%, which was low by historical standards.

Is ^TNX the same as the 10-year yield?

It tracks the same thing. ^TNX is an index of the 10-year Treasury yield and moves with it; small differences come from timing and calculation method.

Summary

The 10-year Treasury yield is the benchmark long-term interest rate: a decade of expected short rates plus a term premium, set every second in the Treasury market. Its monthly average climbed from 2.83% in 1953 to 15.32% in 1981, fell to 0.62% in 2020, and reached 4.99% in September 2026, the highest since 2007. Splitting it into a TIPS real yield and breakeven inflation shows what a move means; the 3.86-point rise from August 2021 to October 2026 was entirely a rise in real yields, with breakeven inflation unchanged at 2.38%. Because mortgages, corporate debt and stock valuations price off it, and because it can move against the Fed, it is worth watching on its own terms.
