Treasury Bills vs. Notes vs. Bonds: A Practical Comparison

The maturity is the first distinction

Treasury bills are short-term marketable securities that mature in one year or less. Treasury notes generally mature in more than one year and up to ten years, while Treasury bonds generally mature in more than ten years. The categories describe the scheduled repayment date, not a promise that the market price will remain stable before maturity.

Bills are commonly issued at a discount and pay the difference between the purchase price and the amount due at maturity. Notes and bonds generally pay a fixed coupon on a schedule and return principal at maturity. The payment pattern matters when matching security cash flows to a bill, tuition payment, or other known need.

• Maturity tells you when the Treasury is scheduled to return principal.
• A coupon is a cash-flow feature, not the same as the investor’s yield.
• Selling before maturity exposes the investor to the current market price.

Price, yield, and interest-rate sensitivity

After issuance, Treasury securities trade at prices that move with market yields, expectations, liquidity, and time remaining. When comparable yields rise, an existing fixed coupon is less attractive and its price generally falls. When yields fall, the existing coupon can become more valuable and its price generally rises.

Longer maturities usually carry more duration and therefore more sensitivity to yield changes, although the exact exposure depends on coupon and cash-flow timing. A short bill may have limited price volatility but greater reinvestment risk when it matures and the next bill is available at a different yield.

Choose by cash-flow job

A ladder can spread maturity dates so that principal returns at regular intervals. A bill may fit a reserve needed within months; a note may fit a medium-term goal; a bond may provide longer scheduled income but can fluctuate more in a brokerage account. The right choice is tied to the date and flexibility of the spending need.

If the money must be available on a specific date, use a maturity that leaves a margin for settlement and avoid relying on a favorable sale price. If the goal is income, compare coupon timing, yield to maturity, reinvestment assumptions, and tax treatment rather than selecting the highest stated coupon.

Direct Treasury versus a bond fund

Holding an individual Treasury to maturity provides a scheduled principal repayment if the issuer meets its obligation, but it does not guarantee a profit after inflation or taxes. A bond fund does not mature as a whole; it continuously buys and sells securities, so its net asset value can remain exposed to duration and flows.

TreasuryDirect, a broker, and a fund each have different access, pricing, liquidity, reinvestment, and recordkeeping features. Compare transaction costs, bid-ask spread, transfer rules, and whether automatic reinvestment is helpful or creates an unwanted rollover.

Risks that remain

Treasuries carry interest-rate, inflation, reinvestment, liquidity, and opportunity-cost risk. A federal guarantee of timely principal and interest does not guarantee purchasing power or the price received if an investor sells early. State and local tax treatment can differ from federal treatment, while individual circumstances affect the after-tax result.
