A bond fund can therefore lose value even if it holds U.S. Treasury securities: Treasury backing addresses the issuer’s credit risk, not the fund’s exposure to changing market prices. To assess that exposure, check the fund’s duration, maturity profile, holdings and stated risks, then consider when you might need the money.
Why rising yields can lower bond prices
A conventional fixed-rate Treasury note or bond pays a coupon set at auction, while its market price changes as yields change. When newly available market yields are higher than the coupon on an existing bond, investors may pay less for that bond. The lower price brings its yield to maturity in line with prevailing yields. TreasuryDirect explains the relationship: when yield to maturity exceeds the coupon rate, a note or bond sells below par; when yield is lower, it sells above par. Treasury notes and bonds pay interest every six months. TreasuryDirect: Treasury notes
The SEC illustrates the effect with a hypothetical 10-year Treasury with a 3% coupon and $1,000 face value. After a hypothetical market-rate increase from 3% to 4%, with nine years remaining, the example shows a price of $925 rather than $1,000 and a yield to maturity of 4%. This is an illustration, not a rule that every one-percentage-point yield move causes the same price change; the result depends on the security’s cash flows and remaining maturity.

How rate changes affect a bond fund
A bond fund owns bonds or other debt securities. If the market value of its holdings falls, the value of the portfolio—and typically the fund’s net asset value (NAV)—can fall too. Treasury holdings do not prevent this kind of market-price loss. The SEC notes that investors can lose money in bond funds, including funds that invest only in U.S. government bonds or insured bonds.

A yield increase alone does not determine a fund’s total return. A fund may continue to receive interest, reinvest proceeds from maturing or sold holdings at prevailing yields, and alter its portfolio over time. Those factors do not guarantee that income will quickly offset a price decline; the outcome depends on the fund and the market path.
Interest-rate risk is distinct from whether an issuer makes its scheduled payments. A Treasury’s backing can mean less issuer credit risk than many other debt investments, but it does not eliminate the risk that its market value—and the value of a fund holding it—will decline when yields change.
How to assess a fund’s interest-rate risk
Start with the fund’s latest prospectus and shareholder report, as the SEC recommends. Use the fund’s reported duration and current holdings rather than relying on a broad label such as “short-term” or “government” as a precise measure of risk. Investor.gov: Mutual Funds and ETFs
- Duration: A measure of sensitivity to interest-rate changes. Longer duration generally means greater sensitivity, all else equal. It is not a guaranteed-loss forecast or a promise of the fund’s realized return. FINRA: Bond Funds
- Maturity profile: Check how long the fund’s bonds have until maturity. Longer maturities generally bring more interest-rate risk than otherwise comparable shorter maturities.
- Holdings and credit quality: Identify whether the portfolio holds Treasuries, corporate debt, mortgage-backed securities or other instruments. Different holdings can add risks beyond Treasury yield movements; lower-quality corporate debt, for example, can involve more credit risk than Treasury debt.
- Other stated risks: Read the prospectus for credit, interest-rate and prepayment risks. A fund’s results may be affected by more than changes in Treasury yields.
- Your time horizon and liquidity needs: Consider whether you might have to sell during a decline. A potential recovery is not useful protection if you need access to the money before it occurs.
How to compare two bond funds
Compare the funds’ current disclosures on the same dimensions. A fund’s category or name alone does not establish how much rate or credit risk it carries.
| What to compare | What to look for |
|---|---|
| Duration and maturity exposure | Reported duration and the maturity profile of holdings; longer exposure generally means greater rate sensitivity, all else equal. |
| Portfolio composition and credit quality | The types of securities held and the quality of their issuers, including whether the portfolio holds Treasuries, corporate debt or mortgage-backed securities. |
| Stated risks | Interest-rate, credit and prepayment risks described in each fund’s current prospectus. |
| Objective and fees | Each fund’s stated investment objective and current fee disclosures; do not assume two funds in the same category have identical costs or aims. |
What this means for your decision
Assess a fund by its actual duration, maturities, holdings and disclosed risks, alongside the point at which you may need to sell. Treasury exposure can reduce issuer credit risk relative to some alternatives, but it does not shield a bond fund’s value from rising yields. This is general investor education, not an individualized investment recommendation.
