BKAG vs GBND

BKAGABNY Mellon Core Bond ETF

GBNDBGoldman Sachs Core Bond ETF

In short

BKAG A core bond index fund that charges nothing. BKAG tracks the same Bloomberg US Aggregate benchmark the giants track, at a 0.00% expense ratio, and has been doing it since 2020.

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

BKAG The fund seeks to track the Bloomberg US Aggregate Total Return Index.

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

• BKAG A 0.00% expense ratio. The median fund in the core bond group charges 0.36%, and even the cheap giants (BND, SPAB, SCHZ) charge 0.03%.
• Tracks the Bloomberg US Aggregate Total Return Index tightly, one of the closest index-following records in its peer group.
• Broad by design: roughly 4,000 bonds in the portfolio, with distributions paid monthly rather than quarterly.
• A multi-billion-dollar fund from BNY Mellon, wrapped in a standard 1940 Act ETF structure with no exotic mechanics.

• 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

• BKAG Rate risk is the trade-off. This is full-market bond exposure, and bond prices move opposite interest rates. Volatility is the weakest part of its profile.
• Moderately traded, not one of the volume monsters in the category. Spreads and limit orders matter more here than with the largest core bond names.
• At zero, the fee edge over 0.03% rivals is real but small in dollar terms, so tracking and trading costs do more of the work.

• 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.
