What Is a Treasury Bond?

A Treasury bond is a debt security issued by the U.S. government as a way to finance government spending. It's backed by the full faith and credit of the United States and is considered the safest bond investment.

How Treasury Bonds Work

You lend money to the U.S. government. The government pays you interest (the coupon) and returns your principal at maturity.

Example: 10-year Treasury at 4% interest

• You pay: $1,000
• Annual interest: $40/year
• At maturity: Receive $1,000 + final $40 payment
• Total received: $400 in interest + $1,000 principal

This is guaranteed by the U.S. government.

Types of Treasuries

Treasury Bills (T-Bills):

• Maturity: <1 year (typically 4-week, 13-week, 26-week, 52-week)
• No coupon (interest) payments
• Sold at discount (pay $990 for $1,000 bill; earn $10)
• Safest, most liquid short-term investment
• Current yield: ~5% (varies with rates)

Treasury Notes:

• Maturity: 2-10 years
• Semi-annual coupon payments
• Most actively traded
• Current yields: 3-5% (varies with maturity)

Treasury Bonds:

• Maturity: 20-30 years
• Semi-annual coupon payments
• Least actively traded
• Highest yields (compensation for long duration)
• Current yields: 4-5%

Why Treasury Bonds Are Safe

Zero default risk: The U.S. government can print money and always pay its obligations

Backed by full faith and credit: The U.S. has never defaulted

Liquid: Treasuries are the most actively traded bonds globally; you can sell anytime

Global reserve currency: The dollar's status as reserve currency means constant demand for Treasuries

This is why Treasury yields are the lowest of all bonds. Safety is valuable.

The Yield Curve

The yield curve plots Treasury yields by maturity:

Normal curve (usually):

• 2-year Treasury: 3%
• 5-year Treasury: 3.5%
• 10-year Treasury: 4%
• 30-year Treasury: 4.5%

Longer maturity = higher yield (compensation for duration risk)

Inverted curve (recession signal):

• 2-year Treasury: 5%
• 10-year Treasury: 4.5%
• Short-term yields > long-term yields

An inverted curve historically predicts recessions 12-18 months later.

Flat curve:

• All maturities paying similar yields
• Rare; brief transition between normal and inverted

Treasury Yields and Economic Conditions

Rising yields (rates going up):

• Often signal strong economy
• Fed raising rates to fight inflation
• Good for savers (higher rates), bad for borrowers
• Bond prices fall (negative correlation)

Falling yields (rates going down):

• Often signal weak economy
• Fed cutting rates to stimulate growth
• Bad for savers, good for borrowers
• Bond prices rise

Treasury Prices and Interest Rates

Treasury prices move inversely to interest rates:

Example: 10-year Treasury, 4% coupon, $1,000 face value

Interest rates fall to 2%:

• Your 4% Treasury is more valuable
• Someone will pay $1,200 for it
• Price up, rate down (inverse relationship)

Interest rates rise to 6%:

• Your 4% Treasury is less valuable
• You must discount it to $850 to find buyer
• Price down, rate up

Duration and Risk

Longer-maturity Treasuries are riskier (more sensitive to rate changes):

2-year Treasury duration: ~2 years (price changes 2% if rates change 1%)

10-year Treasury duration: ~8 years (price changes 8% if rates change 1%)

30-year Treasury duration: ~20 years (price changes 20% if rates change 1%)

Long-term Treasuries are volatile; short-term Treasuries are stable.

Treasury Yields as Anchors

All other interest rates reference Treasury yields:

Mortgage rates: 10-year Treasury yield + 1.5-2.5%

• If 10-year Treasury is 4%, mortgages are ~5.5-6.5%

Corporate bond rates: Treasury yield + credit spread

• Safe company bonds: Treasury + 1%
• Risky company bonds: Treasury + 3-5%

Auto loan rates: Treasury rates + spread

This is why Federal Reserve policy (which influences Treasury yields) affects the entire economy. Lower Treasury yields mean cheaper mortgages, auto loans, business loans.

Treasury Holdings

Who owns Treasuries:

• Federal Reserve (owns ~$5 trillion)
• Foreign central banks (China, Japan)
• Mutual funds and pension funds
• Individual investors

Why:

• Safest investment
• Liquid (easy to buy/sell)
• Stable income

Treasury vs. Corporate Bonds

Treasuries:

• Zero default risk
• Lower interest rates (3-5%)
• Most liquid

Corporate bonds:

• Credit risk (company might default)
• Higher interest rates (4-7%)
• Less liquid

The difference (corporate yield - Treasury yield) is called the "credit spread." Wide spreads (companies paying much more) signal recession fears.

Historical Treasury Yields

2019: 1.6% (10-year) 2020: 0.6% (COVID panic, Fed cuts to zero) 2021: 1.5% (recovery) 2022: 4.2% (Fed rate hikes to fight inflation) 2024: 4.0% (stabilized)

Yields change dramatically with economic conditions.

Advantages of Treasury Bonds

1. Safety: Zero default risk 2. Liquidity: Easy to buy/sell 3. Predictability: Know exactly what you'll receive 4. Tax-exempt from state taxes: Federal tax applies; state/local taxes don't 5. Portfolio stabilization: Negative correlation with stocks

Investment Strategy

For stability (bonds are your core holding):

• 100% Treasury bonds/notes
• Laddered approach (buy 2-year, 5-year, 10-year, 30-year to spread out maturity)
• Or use Treasury ETF for simplicity

For diversified portfolio:

• 40% stocks
• 40% Treasury bonds
• 20% cash/short-term Treasuries

The Bottom Line

Treasury bonds are the safest bonds globally. Zero default risk, liquid, and stable. Lower returns than corporate bonds but much lower risk.

For most investors, Treasury bonds (or bond index funds containing Treasuries) are the core fixed-income holding. They provide stability and negative correlation with stocks, essential for portfolio risk management.
