BKAG vs EUSB

BKAGABNY Mellon Core Bond ETF

EUSBAiShares ESG Advanced Universal USD 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.

EUSB A total-bond-market build with a conscience clause: thousands of taxable dollar bonds, screened for ESG ratings and stripped of fossil fuel issuers, at a fee well under the typical broad bond ETF.

Stated mandate

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

EUSB The Fund seeks to track the Bloomberg MSCI US Universal Choice ESG Screened Index, an index of U.S. dollar-denominated taxable bonds with favorable ESG ratings and extensive screens, including fossil-fuel exclusions.

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.

• EUSB Charges 0.12% a year, well below the median fee in its broad-bond group and cheap for a rules-screened portfolio.
• The screens are the product: favorable ESG ratings plus extensive exclusions, fossil fuels included, written into the index rather than left to a manager's mood.ishares.com
• Spreads exposure across several thousand US dollar taxable bonds and pays monthly, so the income cadence is steady.
• Delivers the mandate it advertises, one of the tighter ESG implementations among broad bond funds we grade.

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.

• EUSB Screening changes the mix. Cutting fossil fuel issuers means the portfolio's sector map and results can diverge from a plain total-bond index.
• Cheap, not cheapest: unscreened aggregate peers like BND, SPAB and SCHZ run 0.03%.
• Smaller and less actively traded than the core bond giants, which can show up as wider bid-ask spreads on larger orders.
