AGG vs GBND

AGGAiShares Core U.S. Aggregate Bond ETF

GBNDBGoldman Sachs Core Bond ETF

In short

AGG Launched in 2003, one of the first funds to pack the entire U.S. investment-grade bond market into a single ticker: Treasuries, corporates and mortgage bonds, three basis points a year, cash paid monthly.

GBND Goldman's active answer to the Agg: a multi-sector bond team trading government, mortgage, corporate and asset-backed debt for 0.25%, net of a waiver through December 29, 2026.

Stated mandate

AGG The fund seeks to track the Bloomberg U.S. Aggregate Bond Index, providing broad exposure to the total U.S. investment-grade bond market.

GBND The Fund seeks total return through capital appreciation and income. It invests primarily in investment-grade core fixed-income securities, including government, mortgage-backed, corporate, and asset-backed debt.

Why people hold it

• AGG 0.03% a year against a peer-group median near 0.36%. On a bond fund, the fee comes straight out of the coupon, so the gap matters more than it looks.
• A $100 billion-plus fund and very actively traded, the kind of depth that keeps bid-ask costs down for retail-sized orders.
• Tracks the Bloomberg U.S. Aggregate closely, with one of the tightest index-following records in its peer group. Income is distributed monthly.
• Running since 2003, giving it one of the longest track records among U.S. bond index ETFs.

• GBND Active by design: Goldman's multi-sector bond team picks across Treasuries, agency mortgages, corporates and asset-backeds, using futures, swaps and TBAs to steer duration.gs.comsec.gov
• Costs 0.25% net of a waiver through December 29, 2026, below the category median and under same-index active rivals DBND (0.45%), FIXT (0.40%) and CPLS (0.30%).
• Pays monthly and spreads risk across roughly 700 investment-grade bonds, so no single issuer carries the portfolio.

Worth knowing

• AGG Investment grade and U.S. dollar only. High-yield debt and foreign bonds sit outside the mandate, so this is designed as core ballast rather than a yield hunt.
• Rate risk comes as it comes. The index gets tracked whether yields rise or fall, with no manager stepping in to shorten duration.
• The same index is sold by SPAB, SCHZ and BBAG at the same 0.03%. The portfolio is the commodity here; scale and trading depth are the tiebreakers.

• GBND The index twins are far cheaper: AGG, BND, SPAB and SCHZ all run 0.03% on the same benchmark, so the active calls here start from a wider fee gap.
• Volume runs lighter than the category's index giants, which can mean wider bid/ask spreads; the issuer posts a 30-day median spread on the fund page.gs.com
• Launched June 24, 2025, so the track record is short and its risk picture rests on limited history.
