Treasury Yield

Quick Definition

Treasury yield is the effective annual interest rate earned by investors who hold U.S. government debt obligations (Treasury bills, notes, and bonds) to maturity. Treasury yields are the world's most important interest rate benchmark — the baseline "risk-free rate" against which all other financial assets are priced.

What It Means

When the U.S. government needs money, it borrows by selling Treasury securities. Investors buy these securities knowing the U.S. government will repay them — the world's most creditworthy borrower. The yield on these securities is not just an interest rate; it is the foundational rate of the entire global financial system.

Every other borrowing rate in America — your mortgage, your car loan, corporate bond yields, credit card rates — is built on top of Treasury yields. When the 10-year Treasury yield moves, it ripples through the entire economy within days.

Types of Treasury Securities

Total outstanding: Over $26 trillion as of 2024 — the largest bond market in the world.

How Treasury Yields Work

The Price-Yield Relationship

Treasury yields and prices move in opposite directions. This inverse relationship is the most important concept in fixed income:

Example: 10-year Treasury Note

• Face value: $1,000
• Coupon rate: 4% (pays $40/year = $20 every 6 months)
• If market price = $1,000: yield = 4.0%
• If market price falls to $950: yield rises to approximately 4.56%
• If market price rises to $1,050: yield falls to approximately 3.48%

When investors sell Treasuries (price falls), yields rise. When investors buy Treasuries (price rises), yields fall.

Why this matters: When you hear "Treasury yields are rising," it means bond prices are falling — investors are selling. When "yields fall," bond prices are rising — investors are buying.

What Moves Treasury Yields

The Treasury Yield Curve

The yield curve plots yields across all Treasury maturities simultaneously. Its shape tells you what the bond market expects for the economy and interest rates.

Normal (Upward Sloping) Yield Curve

Yield (%)
    5.5 |                                      ___
    5.0 |                             ________/
    4.5 |                    ________/
    4.0 |           ________/
    3.5 |__________/
        |__________________________________ Maturity
         1mo  3mo  6mo  1yr  2yr  5yr  10yr  30yr

Long-term yields are higher than short-term yields. This is the normal shape because:

• Investors demand more yield for longer-duration risk
• Markets expect rates to be higher in the future
• Historically associated with economic expansion

Inverted Yield Curve

Yield (%)
    5.5 |___________
    5.0 |           \___________
    4.5 |                       \___________
    4.0 |                                   \_______
        |__________________________________ Maturity
         1mo  3mo  6mo  1yr  2yr  5yr  10yr  30yr

Short-term yields exceed long-term yields. The inverted curve:

• Has preceded every U.S. recession since 1955 with only one false signal
• Signals market expectation that the Fed will cut rates in the future (due to economic slowdown)
• The 2-year vs. 10-year inversion in 2022-2023 was the deepest since 1981

Flat Yield Curve

Short-term and long-term yields are roughly equal. Typically a transition between normal and inverted — often occurs in mid-cycle when the Fed is actively hiking rates.

The Most Watched Treasury Yields

The 10-Year Treasury Yield

The single most important interest rate in the world. The 10-year yield:

• Sets mortgage rates: 30-year fixed mortgage = 10-year Treasury yield + ~150-200 basis points
• Benchmarks corporate bonds: Investment-grade corporates trade at spreads above the 10-year
• Values equities: The "equity risk premium" is measured against the 10-year risk-free rate
• Signals economic expectations: Rises on growth/inflation optimism; falls on recession fear

Historical 10-year Treasury yield milestones:

The 2-Year Treasury Yield

The 2-year yield is the most sensitive to Federal Reserve policy expectations. Because 2 years is close enough to the near-term policy horizon, the 2-year moves closely with Fed funds rate expectations.

2-year yield as a Fed barometer:

• 2-year yield above Fed funds rate: Market expects rate hikes
• 2-year yield below Fed funds rate: Market expects rate cuts

The 3-Month T-Bill Yield

The 3-month T-bill yield is the purest expression of current short-term risk-free rates. It is used as the short-term risk-free rate in financial models (CAPM, options pricing) and as a benchmark for money market funds.

Real Yields vs. Nominal Yields

Nominal yield: The stated yield on a Treasury note (e.g., 4.5%)

Real yield: Yield adjusted for inflation

Real Yield = Nominal Yield - Inflation Rate (expected)

TIPS (Treasury Inflation-Protected Securities) yield the real rate directly. When you see "10-year TIPS yield is 2.0%," that means you earn 2.0% above inflation, whatever inflation turns out to be.

When TIPS yields are negative (as they were from 2020-2022), the bond market was saying real returns on safe assets are negative — which pushed investors into riskier assets seeking positive real returns.

Treasury Yields and Mortgage Rates

The connection between Treasury yields and mortgage rates is direct and powerful:

The spread mechanism:

• 30-year fixed mortgage = 10-year Treasury yield + Mortgage spread
• Mortgage spread typically 150-200 basis points (1.5-2.0%)
• Spread widens in volatile or uncertain markets (lenders charge more premium)

Historical example:

The 2022-2023 spike in mortgage rates (from ~3% to ~8%) was directly caused by the rise in 10-year Treasury yields as the Fed aggressively hiked rates to fight inflation.

How to Buy Treasury Securities

TreasuryDirect.gov

The U.S. Treasury's direct purchase platform — no broker, no fees:

• Available to U.S. citizens with a Social Security number
• Buy T-bills, notes, bonds, TIPS, and I-Bonds directly
• Minimum purchase: $100
• Available in $100 increments
• No trading after purchase (hold to maturity or sell through a broker)

Through a Brokerage Account

Any brokerage (Fidelity, Schwab, Vanguard, TD Ameritrade) allows Treasury purchases:

• Secondary market and new issue auctions available
• Can sell before maturity
• Treasury ETFs available (SHY, IEF, TLT, TIPS ETF)

Treasury ETFs

Longer-duration ETFs (TLT) are significantly more volatile — they appreciate substantially when rates fall and decline sharply when rates rise.

Key Points to Remember

• Treasury yields are the global risk-free benchmark — every other borrowing rate is set as a spread above comparable Treasury yields
• Yields and prices move inversely: When Treasury prices fall (selling), yields rise; when prices rise (buying), yields fall
• The 10-year Treasury yield directly drives mortgage rates — typically 150-200 basis points above it
• An inverted yield curve (2-year > 10-year) has preceded every U.S. recession since 1955
• Real yields (TIPS yields) matter as much as nominal yields — a 4.5% nominal yield with 3% inflation delivers a much lower real return than 4.5% with 1.5% inflation

Frequently Asked Questions

Q: How do Federal Reserve rate decisions affect Treasury yields? A: The Fed directly controls the federal funds rate (overnight bank lending rate), which pushes short-term Treasury yields (T-bills, 2-year notes) almost immediately. Long-term yields (10-year, 30-year) are influenced by Fed policy but more driven by economic growth and inflation expectations over the full horizon. The Fed can cut short-term rates while long-term yields rise if the market expects higher long-term growth and inflation — this is called "yield curve steepening."

Q: Is now a good time to buy Treasury bonds? A: Depends on your goals and interest rate expectations. If rates fall from here, long-term Treasury bonds (TLT) will appreciate significantly. If rates rise, long-term bonds lose value. Short-term T-bills lock in current yields with minimal price risk. For safety-oriented investors and those building bond ladders, Treasuries at 4-5% offer attractive risk-free income compared to the near-zero yields of 2020-2021.

Q: What is the relationship between Treasury yields and the stock market? A: Rising Treasury yields generally pressure stocks because: (1) higher risk-free rates make stocks relatively less attractive, (2) higher yields increase borrowing costs for companies, and (3) the discount rate used to value future corporate earnings rises, reducing present values. The 2022 stock market decline coincided directly with the sharp rise in Treasury yields. However, the relationship is not mechanical — stocks can rise alongside rising yields if economic growth is strong enough to offset the higher discount rate.

Q: Are Treasury bonds a good inflation hedge? A: Standard Treasury notes and bonds are poor inflation hedges — their fixed coupon payments lose purchasing power as inflation rises. TIPS (Treasury Inflation-Protected Securities) are designed explicitly as inflation hedges — their principal adjusts with CPI. I-Bonds (Series I savings bonds) from TreasuryDirect.gov are the most inflation-protective option for individual investors, as their yield adjusts every six months based on current CPI.
