Before buying a long-term U.S. Treasury bond, check when you may need the money, the bond’s yield at its actual purchase price, and whether you can tolerate a price loss if you sell before maturity. Treasury bonds have 20- or 30-year terms and pay interest every six months; the U.S. government’s backing does not guarantee a stable resale price or protect fixed payments from inflation.
1. Match the maturity to when you may need the money
Treasury bonds are long-term marketable securities with 20- or 30-year terms and semiannual interest payments, according to the U.S. Treasury’s TreasuryDirect overview. A bond’s term is not a requirement to hold it all the way to maturity: marketable securities can be sold earlier. But an early sale takes place at the market price, which may be above or below face value.

Start with the date you expect to use the principal, not just the interest payment schedule. If you might need the money well before the bond matures, consider whether you could leave it invested through a price decline rather than sell at a loss. A shorter-maturity security may fit a nearer cash need better; longer maturities generally carry greater interest-rate risk than otherwise similar shorter bonds.

2. Compare yield to maturity with the price you will pay
The coupon, or stated interest rate, determines interest paid on the bond’s face value. It is not, by itself, the return a new buyer earns, because the purchase price can be below, at, or above face value. Treasury explains that a bond’s price is below par when its yield to maturity is higher than its stated interest rate, and above par when its yield is lower. See TreasuryDirect’s explanation of pricing and interest rates.
#1 Best Overall
Yield to maturity is Treasury’s stated annual rate of return measure for a security. Evaluate it alongside the price in the transaction quote and your plan for holding the bond. If you hold the security to maturity and still own it then, the principal returned is its face value; that does not erase the effect of having paid a premium or the opportunity cost of being unable to use that money elsewhere.
- Check the specific bond’s price and yield, not only its coupon.
- Confirm the quote is current and note whether it is an auction offering or a secondary-market transaction.
- Review any spread, fee, or other transaction term shown by the bank or brokerage handling the purchase.
3. Understand what can happen if interest rates rise
When market interest rates rise, existing bond prices generally fall. A long-term bond can be more exposed to this effect than a similar shorter-term bond because its fixed payments extend further into the future. The exact resale price depends on market conditions when you sell; a quote today cannot establish what that price will be later.
This matters most if your plans could force an early sale. If you can hold to maturity, interim market-price changes do not change the scheduled coupon payments, but they can still matter if your cash needs or circumstances change. Avoid choosing a long term solely on a view about where rates are headed.
4. Separate Treasury backing from investment risks
U.S. Treasury securities are backed by the full faith and credit of the U.S. government. That backing concerns the government’s payment obligation; it does not prevent the market value from falling before maturity or preserve the purchasing power of fixed payments.
Investor.gov identifies credit, interest-rate, inflation, liquidity, and call risks among bond risks generally. For a Treasury bond buyer, focus particularly on interest-rate risk if selling early and inflation risk over a long holding period. As Investor.gov puts it, “Inflation reduces purchasing power, which is a risk for investors receiving a fixed rate of interest.” Read its bond FAQ for the broader risk discussion.
5. Decide whether fixed nominal payments or TIPS fit better
A conventional Treasury bond pays interest based on face value, so its nominal coupon payments are fixed. If inflation protection is a priority, compare it with Treasury Inflation-Protected Securities (TIPS), which have 5-, 10-, or 30-year terms. Treasury says TIPS principal adjusts with the Consumer Price Index; interest is paid on adjusted principal, so payment amounts can vary. At maturity, the holder receives the greater of adjusted principal or original principal. See TreasuryDirect’s TIPS overview.
| Feature | Long-term Treasury bond | TIPS |
|---|---|---|
| Terms described by Treasury | 20 or 30 years | 5, 10, or 30 years |
| Principal and interest basis | Interest is paid on face value; nominal coupon payments are fixed. | Principal adjusts with the Consumer Price Index; interest is paid on adjusted principal and can vary. |
| Principal at maturity | Face value if held to maturity. | The greater of adjusted principal or original principal. |
Treasury’s TIPS page says federal taxes apply to interest and principal changes may affect federal taxes; it also says TIPS are not subject to state or local taxes. Tax treatment can depend on current rules and personal circumstances, so verify it before buying. A comparison should account for maturity date, yield and purchase price, potential early-sale price, inflation treatment, purchase-channel terms, and applicable taxes—not just coupon rates.

Treasury identifies banks and brokerages as places where marketable securities are available. The quote, transaction costs, and account terms depend on the channel you choose. Check the actual offering or secondary-market quote and any fees directly with that provider; do not treat historical examples on Treasury pricing pages as current market quotes. Current yields and an individual tax outcome cannot be inferred from the product description alone.
Quick Recap
- Confirm the security’s maturity date and whether it is newly issued or being bought in the secondary market.
- Record the transaction price and yield to maturity shown for that specific purchase.
- Ask the provider about fees, spreads, settlement, and how to sell before maturity.
- Check current tax guidance for your situation, especially if considering TIPS principal adjustments.
