How it works
The prospectus filed June 18, 2026 says the fund tracks the Bloomberg U.S. Government/Credit Bond Index. To qualify, a bond must be in U.S. dollars, pay a fixed rate, have at least one year left to maturity and have at least $300 million outstanding. That covers Treasuries, government-related debt and investment-grade corporate bonds, meaning bonds rated as having lower default risk. Floating-rate notes, private placements and Eurobonds are left out. Bonds are weighted by market value, so the largest issuers count the most. The index is updated on the last business day of each month.
The index held 10,082 bonds as of February 28, 2026. The fund doesn't buy them all. BlackRock uses "representative sampling," which means owning a smaller set of bonds chosen to match the index's interest-rate sensitivity, credit quality, maturity and yield. As of August 31, 2026, the fund held 3,215 issues: 60% Treasuries and 31% corporate bonds, with an average maturity of 8.6 years. It may lend up to one-third of its assets to earn extra income. It reported no derivatives on that date.
One point worth checking: the fund's name says "1-10 Year" and "Aggregate," but the prospectus describes an index with no top limit on maturity. The August 2026 holdings also show no large slice of mortgage-backed bonds, which aggregate indexes usually include.
What it really costs
- AGGM charges 0.2% a year, versus an average of 0.08% for the similar funds below (7th of 8, cheapest first).
- Using the prospectus's standard example, $10,000 invested would cost about $20 in the first year and $255 over 10 years (assuming a 5% annual return).
| Cost of $10,000 (SEC example) | 1 yr | 3 yrs | 5 yrs | 10 yrs |
|---|---|---|---|---|
| AGGM | $20 | $64 | $113 | $255 |
Structure and tax notes
- Bond prices move opposite to interest rates; the longer the maturities it holds, the more its price reacts to rate changes.
In a retirement portfolio
It offers broad, high-quality U.S. bond exposure, mostly Treasuries and investment-grade corporate bonds, that could anchor the bond side of a portfolio, though cheaper similar funds exist.
AGGM pays income monthly, with a trailing 12-month yield of 3.92% as of October 27, 2026. In the 2008 crisis it gained 6.6% while stocks fell. Its 8% drop in March 2020 recovered within about three months. 2022 was harder. As interest rates rose, it lost 13.8% for the year, and the slide that began in January 2022 took 40.6 months to recover. Its deepest fall, 19.7% from August 2020 to October 2022, had not been fully made up as of October 27, 2026. Anyone selling shares for cash during a stretch like that would have locked in losses.
At 0.20% a year, it costs $20 on $10,000 in the SEC's standard example. That is more than similar Vanguard and iShares funds charging 0.03%. Past results don't predict the future, and a plan should look at the whole portfolio, not one fund.
Who it may suit — and who should look elsewhere
May suit
- Investors wanting one fund that holds mostly U.S. Treasuries (60%) plus investment-grade corporate bonds (31%), as of August 31, 2026.
- Retirees who value monthly income. The trailing 12-month yield was 3.92% as of October 27, 2026.
- Those seeking bonds that moved little with stocks. It gained 6.6% through the 2008 crash, and its one-year beta was 0.1.
Look elsewhere if
- Cost-focused investors. Its 0.20% expense ratio is several times the 0.03% charged by BIV, BND, AGG and SCHZ.
- Anyone wanting strictly 1-10 year or mortgage-backed bonds. The prospectus describes a Government/Credit index with no maturity cap.
- Those who may need to sell in a rising-rate year. It fell 13.8% in 2022 and took 40.6 months to recover.

Questions investors ask
Does AGGM pay monthly dividends?
Yes. AGGM pays income monthly. Over the 12 months to October 27, 2026, it paid $3.95 per share, a trailing yield of 3.92%. That figure looks back, not forward. The prospectus warns that income can fall when interest rates drop, because maturing or called bonds may be replaced with lower-yielding ones.
What index does AGGM track?
The prospectus filed June 18, 2026 names the Bloomberg U.S. Government/Credit Bond Index. It holds Treasuries, government-related debt and investment-grade corporate bonds with at least one year to maturity, and it has no stated top limit on maturity. The fund's name refers to 1-10 year aggregate bonds, so it is worth checking the latest prospectus. For comparison, the prospectus measures performance against the Bloomberg US Universal Index.
What's the difference between AGGM and BIV?
The main differences are cost and size. Vanguard's BIV is AGGM's closest match by maturity and issuer mix. BIV charges 0.03% a year against AGGM's 0.20%. BIV held about $52.4 billion as of June 30, 2026, against AGGM's roughly $107 million as of August 31. Its bonds are a bit shorter, averaging 7.5 years against 8.6. BIV also returned more: 5.7% a year over three years through October 30, 2026, while AGGM returned 4.7% through October 27.
How much did AGGM lose in 2022?
AGGM lost 13.8% in 2022, its worst calendar year, according to its prospectus. Its weakest quarter was January to March 2022, at -6.26%. Bond prices fall when interest rates rise, and rates climbed sharply that year. Measured from its peak on January 3, 2022, the fund did not get back to that level until February 13, 2026, about 40.6 months later.
Is AGGM a safe investment?
It is lower-risk than most stock funds, but it is not risk-free. Its three-year volatility was 4.8% as of October 27, 2026, and its one-year beta was 0.1. Beta measures how much a fund moves with the stock market, and 0.1 means very little. Even so, it fell 19.7% from August 2020 to October 2022 and had not fully recovered by October 27, 2026. Rate changes and credit problems at bond issuers can both cause losses.
