U.S. Treasury securities are among the most widely used fixed-income investments in the world. They allow investors to lend money to the U.S. federal government in exchange for interest payments or a predetermined return, depending on the type of security purchased.

Three of the most important types are Treasury bills (T-bills), Treasury notes, and Treasury bonds. Although all three are backed by the U.S. government, they differ in maturity, interest structure, price behavior, and the role they can play in an investment portfolio.

Understanding these differences can help investors decide where to keep short-term savings, generate regular income, or build a long-term investment strategy.

The central distinction is maturity:

• Treasury bills: Short-term government securities that mature in one year or less.
• Treasury notes: Medium-term government securities with maturities of 2, 3, 5, 7, or 10 years.
• Treasury bonds: Long-term government securities with maturities of 20 or 30 years.

These categories are particularly important for investors in the United States, but international investors may also be able to access U.S. Treasury securities through eligible brokers and financial institutions, subject to local laws, tax rules, and account requirements.

1. What are Treasury bills, Treasury notes, and Treasury bonds?

Treasury bills (T-bills)

Maturity: 4 to 52 weeks for standard marketable bills

Treasury bills are short-term government securities generally sold at a discount to their face value. They typically do not pay periodic interest. Instead, investors receive the face value at maturity, and the difference between the purchase price and face value represents the return, before taxes and applicable costs.

Treasury notes

Maturity: 2 to 10 years

Treasury notes are medium-term securities that generally pay interest every six months. Their market prices fluctuate as interest rates change, so the amount an investor receives upon selling before maturity may be greater or less than the original purchase price.

Treasury bonds

Maturity: 20 or 30 years

Treasury bonds are long-term government securities that generally pay interest every six months. They can provide a long stream of scheduled interest payments, but their market prices can be particularly sensitive to changes in interest rates because of their long maturities.

The three instruments serve different purposes. T-bills are often used for short-term cash management, notes for medium-term goals and income, and bonds for long-term income or interest-rate exposure.

2. Treasury bills vs. notes vs. bonds: Key differences

Feature	Treasury bills	Treasury notes	Treasury bonds
Typical maturity	4–52 weeks	2–10 years	20–30 years
Interest structure	Usually sold at a discount; no periodic coupon	Fixed coupon, generally paid semiannually	Fixed coupon, generally paid semiannually
Principal repayment	Face value at maturity	Face value at maturity	Face value at maturity
Short-term liquidity	Generally high	Generally high in the market	Generally high in the market
Interest-rate sensitivity	Usually lowest	Moderate, depending on maturity	Usually highest
Price volatility	Usually lowest	Moderate to high	Potentially high
Common use	Cash management and short-term goals	Income and medium-term planning	Long-term income and portfolio diversification
Inflation risk	Relevant over the holding period	Relevant over the holding period	More significant over long periods
Early-sale risk	Possible price gain or loss	Possible price gain or loss	Potentially substantial price gain or loss

Note: These are general comparisons. Actual returns and price sensitivity depend on market conditions, the security’s remaining maturity, its yield, and the price paid.

3. How Treasury bills work

Treasury bills are designed for investors who want to invest money for a relatively short period without committing to a multi-year security.

Unlike conventional Treasury notes and bonds, T-bills generally do not provide regular coupon payments. Their return comes from the difference between the amount paid and the face value received at maturity.

Example: Investing $10,000 in a Treasury bill

Suppose an investor purchases a Treasury bill with a face value of $10,000 for $9,800. The bill matures in six months.

Initial investment

$9,800

Amount received at maturity

$10,000

Gross investment return

$200

Illustrative figures, not a current market quotation. Taxes and transaction costs are excluded.

The investor earns $200 over six months, assuming the bill is held to maturity and the payment is made as scheduled.

The simple annualized return on the original amount invested is approximately:

\[ \frac{\$200}{\$9,800}\times\frac{12}{6}\times100 =4.08\% \]

This is a simplified annualization, not the official Treasury bill discount rate or a compounded annual return.

Why investors use Treasury bills

Treasury bills can be useful for:

• Keeping money available for upcoming expenses.
• Holding savings for a few weeks or months.
• Temporarily investing cash while deciding on longer-term investments.
• Building a short-term ladder with staggered maturity dates.
• Reducing exposure to the price fluctuations associated with long-term bonds.

The main limitation is reinvestment risk. When a bill matures, the investor may have to reinvest at a lower interest rate if market yields have fallen.

For example, someone who repeatedly purchases six-month bills might earn a relatively attractive return today but receive a lower return when the next bill is purchased. The yield is not locked in indefinitely.

4. How Treasury notes work

Treasury notes are designed for investors who want scheduled interest payments over a medium-term period.

The U.S. Treasury issues notes with maturities of 2, 3, 5, 7, and 10 years. They generally pay fixed interest twice a year, with the principal repaid at maturity.

Example: Investing $10,000 in a Treasury note

Assume an investor purchases a 5-year Treasury note with:

• Face value: $10,000
• Annual coupon rate: 4%
• Purchase price: $10,000
• Maturity: 5 years

The annual interest payment is:

\[ \$10,000\times4\%=\$400 \]

Because interest is paid semiannually, each scheduled payment is $200.

Interest per payment

$200

Payments over 5 years

10

Total scheduled interest

$2,000

Total principal and interest received

$12,000

Assumes purchase at face value, holding to maturity, no reinvestment of interest, and no default. Taxes and costs are excluded.

This example demonstrates why Treasury notes may suit investors seeking a predictable stream of nominal interest income.

However, a 4% coupon does not necessarily mean the investor’s actual yield is 4%. If the note is purchased above or below face value, its yield to maturity will differ from the coupon rate.

Why investors choose Treasury notes

Treasury notes can be appropriate for:

• Investors who want regular income.
• People saving toward medium-term financial goals.
• Investors who want to lock in a fixed nominal interest rate for several years.
• Portfolio managers seeking exposure to intermediate-term government debt.
• Investors who want to diversify across different maturity dates.

The principal disadvantage is that the investment can lose market value if interest rates rise. This matters particularly when the investor needs to sell before maturity.

5. How Treasury bonds work

Treasury bonds are long-term government securities, generally issued with maturities of 20 or 30 years. Like Treasury notes, they normally pay fixed interest every six months and repay their face value at maturity.

Their long maturities make them particularly relevant to investors who want long-term income or exposure to movements in long-term interest rates.

Example: Investing $10,000 in a Treasury bond

Suppose an investor purchases a 30-year Treasury bond with a face value of $10,000 and an annual coupon rate of 4%.

The scheduled annual interest is:

\[ \$10,000\times4\%=\$400 \]

The investor receives $200 every six months for 30 years.

Semiannual payment

$200

Total payments over 30 years

60

Total scheduled interest

$12,000

Total principal and interest received

$22,000

Illustrative nominal cash flows assuming purchase at face value and holding to maturity. Taxes, costs, and reinvestment returns are excluded.

Although the bond produces $12,000 in scheduled interest over its life, the investor must wait decades for the principal to be repaid. Inflation can significantly reduce the purchasing power of that future money.

Furthermore, the bond’s market value may fluctuate considerably during those 30 years.

Why investors choose Treasury bonds

Treasury bonds may appeal to investors who:

• Want to lock in a nominal coupon rate for a long period.
• Need long-term scheduled income.
• Want to match long-dated liabilities or future financial commitments.
• Believe long-term interest rates may decline and are willing to accept price volatility.
• Want to diversify a portfolio with long-duration government securities.

Long-term bonds are not automatically better investments simply because they pay interest for more years. The purchase price, yield, inflation, time horizon, and future interest-rate environment all affect the final outcome.

6. How interest rates affect T-bills, notes, and bonds

One of the most important differences among these securities is their sensitivity to interest-rate changes.

When market interest rates rise, existing fixed-rate notes and bonds usually fall in price. When market interest rates decline, existing fixed-rate notes and bonds usually rise in price.

This happens because newly issued securities may offer different yields, making existing securities more or less attractive to buyers. TreasuryDirect explains the relationship between coupon rates, market yields, and bond prices in its official pricing guide.

Example of falling market prices

Imagine an investor owns a 10-year Treasury note paying a 3% annual coupon. New Treasury notes with comparable maturities are subsequently issued at yields of 5%.

The existing 3% note is less attractive to a buyer who can obtain a higher yield from a newly issued security. Its market price would generally need to fall to compensate the new buyer.

If market yields instead fall to 2%, the existing 3% note may become more attractive, pushing its price higher.

Market interest rates decline

Existing fixed-rate bond prices generally rise. Long-term bonds often experience the largest percentage price movements.

Market interest rates rise

Existing fixed-rate bond prices generally fall. Longer-duration securities are usually more sensitive to the change.

T-bills are not entirely immune to interest-rate risk. If sold before maturity, their prices can fluctuate too. However, their short maturities generally mean less exposure to changes in interest rates than comparable long-term securities.

What is duration?

Duration is a measure of a bond’s sensitivity to interest-rate movements. Modified duration provides an approximate estimate of the percentage change in price for a given change in yield.

For example, if a security has a modified duration of 7, a 1-percentage-point rise in yield would imply an approximate 7% decline in price, all else equal.

This is only an approximation. The actual price movement can differ, particularly when yields change substantially.

The general relationship is:

• Shorter duration: usually less interest-rate price risk.
• Longer duration: usually greater interest-rate price risk.
• Lower duration: generally less potential price appreciation when rates fall.
• Higher duration: generally greater potential price appreciation when rates fall.

Duration is one reason investors often use T-bills for near-term cash needs and carefully consider their exposure before purchasing long-term Treasury bonds.

7. Comparing investment returns: Which pays more?

There is no permanent rule that Treasury bills, notes, or bonds always offer the highest return. Their yields change with market conditions, investor demand, inflation expectations, and Federal Reserve policy.

The yield curve shows the relationship between Treasury yields and their maturities.

Understanding the Treasury yield curve

Illustrative patterns, not current market data

Short-term yields

Medium-term yields

Long-term yields

In a typical upward-sloping curve, longer maturities offer higher yields. Real yield curves can be flat, inverted, or irregular.

Three possible yield-curve environments

1. Normal or upward-sloping yield curve

Longer-term securities offer higher yields than shorter-term securities. Investors may receive additional compensation for committing money for longer and accepting greater interest-rate and inflation risk.

2. Flat yield curve

Short-term and long-term yields are relatively similar. In this environment, investors may favor shorter maturities if they value flexibility, while others may prefer to lock in a longer-term yield.

3. Inverted yield curve

Short-term yields exceed longer-term yields. This can occur when investors expect future interest rates to decline or when monetary policy is restrictive. An inverted curve does not guarantee a recession or a specific investment outcome.

How to compare yields correctly

When comparing securities, examine their yield to maturity, remaining maturity, purchase price, and transaction costs. Do not compare a Treasury bill’s quoted discount rate directly with a bond’s coupon rate as if they were identical measures.

For notes and bonds, the coupon is calculated on face value, while yield to maturity incorporates the price paid and the expected contractual cash flows.

For T-bills, use an appropriate annualized investment-yield measure when comparing returns with other securities.

8. Risks of Treasury bills, notes, and bonds

U.S. Treasury securities are backed by the full faith and credit of the U.S. government, but this does not eliminate every investment risk.

Risk	Treasury bills	Treasury notes	Treasury bonds
U.S. government payment risk	Generally regarded as very low	Generally regarded as very low	Generally regarded as very low
Interest-rate risk	Usually low	Moderate, depending on duration	Often high
Inflation risk	Over the short holding period	Over the medium term	Potentially substantial over decades
Reinvestment risk	Important when bills mature frequently	Relevant when coupons or principal are reinvested	Relevant for coupon payments and eventual principal repayment
Early-sale price risk	Usually relatively limited	Can be significant	Can be substantial
Currency risk for foreign investors	Depends on the investor’s home currency	Depends on the investor’s home currency	Depends on the investor’s home currency

Inflation risk

Inflation reduces the purchasing power of money over time.

Suppose an investor earns a nominal return of 4% while inflation averages 3%. The approximate real return before taxes and costs is:

\[ \frac{1.04}{1.03}-1\approx0.97\% \]

The investment grows in dollar terms, but its purchasing power grows by less than 1% annually.

For a 30-year Treasury bond, the effect can be particularly important because the coupon and principal are denominated in nominal dollars.

Investors concerned about inflation may also research Treasury Inflation-Protected Securities (TIPS). TIPS are a separate category of Treasury security whose principal adjusts with inflation, subject to their terms. They should not be confused with conventional fixed-principal Treasury notes and bonds.

Liquidity risk

Treasury bills, notes, and bonds are generally actively traded and can often be sold before maturity. Nevertheless, the price received depends on market conditions, and selling may involve transaction costs or bid-ask spreads.

Currency risk for international investors

An investor whose home currency is not the U.S. dollar faces exchange-rate risk. Even if a Treasury security generates a positive dollar return, the investor’s return in their home currency may be lower or negative if the dollar depreciates sufficiently.

9. Which Treasury security is best for different financial goals?

The best choice depends on when the money will be needed and whether the investor prioritizes flexibility, scheduled income, or long-term interest-rate exposure.

For emergency savings and short-term expenses

Consider Treasury bills with maturity dates that match expected cash needs. A short maturity helps limit price sensitivity, although bills are not the same as immediately accessible bank deposits. Keep adequate readily available cash for emergencies.

For goals in two to ten years

Consider Treasury notes with maturities aligned to the planned spending date. A note can provide scheduled interest payments, but selling before maturity can result in a capital loss.

For long-term income and portfolio diversification

Consider Treasury bonds if a long investment horizon suits your goals and you can tolerate potentially substantial price fluctuations. A long maturity does not make a bond automatically more profitable.

For diversified fixed-income investing

A combination of bills, notes, and bonds can distribute maturities across different periods. This may help balance near-term liquidity, income, and exposure to changes in interest rates.

These are general educational guidelines, not personalized investment recommendations.

10. What is a Treasury ladder, and how does it work?

A Treasury ladder is a strategy in which an investor purchases securities with different maturity dates rather than investing all available money in one maturity.

For example, an investor with $20,000 might divide the amount into four equal portions and invest in Treasury bills maturing at different times.

Investment	Amount	Illustrative maturity
Bill A	$5,000	3 months
Bill B	$5,000	6 months
Bill C	$5,000	9 months
Bill D	$5,000	12 months
Total	$20,000

This is a simplified illustration. Actual available terms and auction prices should be checked before investing.

As each bill matures, the investor can use the proceeds for spending or reinvest them in a new security.

Advantages of a Treasury ladder

• Regular access to funds: Maturities are staggered rather than concentrated on one date.
• Reduced timing risk: The entire portfolio is not reinvested at one interest rate.
• Greater flexibility: The investor can adjust the strategy as financial needs change.
• Simplified cash planning: Maturity dates can be aligned with expected expenses.

A ladder does not guarantee the highest possible return. Its value lies in managing maturity dates and reducing dependence on a single reinvestment decision.

Investors can also build ladders using Treasury notes and bonds, although longer-term ladders introduce more interest-rate and price risk.

11. How to buy Treasury bills, notes, and bonds

U.S. Treasury securities can generally be purchased through two main channels: directly from the U.S. Treasury or through a broker or financial institution that offers them.

Option 1: Buy directly through TreasuryDirect

TreasuryDirect is the U.S. government’s official platform for purchasing eligible Treasury securities directly.

The general process is:

1. Check account eligibility and establish an account if you qualify.
2. Link an eligible payment method.
3. Review the available securities and upcoming auction dates.
4. Select the security type and maturity.
5. Submit an order according to the applicable auction rules.
6. Review the transaction confirmation and maturity details.

The direct-purchase route is subject to eligibility requirements. International investors should not assume they can open a TreasuryDirect account simply because they can access the website.

Option 2: Buy through a brokerage account

Many brokerage firms offer Treasury securities through auctions or the secondary market.

A brokerage account may be useful for investors who want access to existing securities, a broader investment portfolio, or the ability to sell before maturity.

Before purchasing, check:

• Whether the broker accepts clients resident in your country.
• The minimum purchase amount.
• Any commissions, markups, or transaction charges.
• Whether the security is bought at auction or in the secondary market.
• The price, yield to maturity, maturity date, and settlement terms.
• The tax treatment in your country of residence.

Official information is available from TreasuryDirect at TreasuryDirect.gov.

12. Treasury bills vs. notes vs. bonds: Tax considerations

Tax treatment depends on the investor’s tax residence, account type, and applicable national laws.

For U.S. federal tax purposes, interest on Treasury bills, notes, and bonds is generally subject to federal income tax but exempt from state and local income taxes. T-bill discount income is generally treated as interest income for federal tax purposes, subject to the applicable rules.

International investors should also investigate:

• Whether U.S. withholding tax applies to their particular circumstances.
• Whether a tax treaty provides any applicable relief.
• How investment income is treated in their country of tax residence.
• Whether capital gains or foreign-exchange gains are taxable.
• Whether additional reporting obligations apply.

A tax exemption in one jurisdiction does not automatically mean the investment is tax-free everywhere. Investors should verify their own obligations with a qualified tax professional.

13. Frequently asked questions

Are Treasury bills safer than Treasury bonds?

Both are obligations of the U.S. government. The main difference is the type and extent of market risk. Treasury bills generally have less interest-rate risk because they mature sooner, while long-term Treasury bonds can experience much larger price movements.

Can I lose money investing in Treasury securities?

Yes. If you sell a security before maturity, you may receive less than you paid. Inflation can also reduce the real value of your returns. Holding a conventional Treasury security to maturity generally allows you to receive its stated principal at maturity, assuming the U.S. government fulfills its obligations, but that does not guarantee a positive real return or eliminate opportunity costs.

Do Treasury bills pay monthly interest?

No. Standard Treasury bills generally do not pay periodic interest. Their return comes from the difference between the purchase price and the face value received at maturity.

Do Treasury notes and bonds pay monthly interest?

No. Standard Treasury notes and bonds generally pay interest every six months.

Which Treasury security is best for beginners?

Treasury bills can be a straightforward starting point for learning about government securities because their maturities are short and their cash flows are easy to understand. However, the appropriate choice depends on the investor’s financial goals, liquidity needs, and access to the market.

Can I sell a Treasury bill, note, or bond before maturity?

Generally, yes. Marketable Treasury securities can be sold in the secondary market, subject to the relevant account and market arrangements. The sale price may be higher or lower than the purchase price.

Are Treasury bills better than savings accounts?

They serve different purposes. Treasury bills may offer an attractive return for money that can remain invested until maturity, but bank savings accounts may provide easier access to cash and may be covered by applicable deposit insurance. Compare after-tax returns, liquidity, fees, and the terms of any deposit protection before deciding.

Can foreign investors buy U.S. Treasury securities?

Many international investors can access U.S. Treasury securities through eligible financial institutions or brokers, but access varies by jurisdiction and provider. Account eligibility, tax documentation, withholding rules, currency exposure, and transaction costs should be reviewed before investing.

What happens when a Treasury security matures?

The principal is repaid according to the security’s terms. For a T-bill, the investor receives the face value. For a note or bond, the investor receives the principal at maturity along with any final interest payment due under the security’s schedule. The investor can then spend or reinvest the proceeds.

Which Treasury security should you choose?

Treasury bills, notes, and bonds serve different purposes within a fixed-income portfolio.

• Treasury bills are generally best suited to short-term cash management and near-term financial goals.
• Treasury notes may be suitable for investors who want scheduled interest income over a medium-term horizon.
• Treasury bonds may suit investors seeking long-term nominal income and who can tolerate greater interest-rate sensitivity.

The most important decision is not simply which security has the highest quoted yield. It is whether the maturity, expected return, liquidity, inflation exposure, and price risk match your financial goals.

For many investors, a combination of maturities can be more useful than choosing only one type. By understanding how these securities work, investors can make more informed decisions about saving, income generation, and long-term portfolio construction.
