BKAG vs BLST

BKAGABNY Mellon Core Bond ETF

BLSTBBluemonte Short Term 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.

BLST One ticket, an actively managed basket of short-duration bond ETFs: Treasuries, corporates, TIPS and securitized debt, with a four-year average maturity ceiling written into the prospectus. Rate risk kept on a short leash.

Stated mandate

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

BLST The Fund seeks total return and income. It is actively managed and obtains at least 80% bond exposure, primarily through underlying funds holding short-duration debt securities.

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.

• BLST The maturity leash is in the prospectus: underlying funds hold debt averaging no more than four years, five years max. Far less rate whiplash than a total bond index.sec.gov
• All-in cost is 0.22% net of a waiver through August 31, 2027 (0.27% gross), and that figure already includes the 0.02% the underlying ETFs charge. Below the category median.sec.gov
• Investment grade is the floor: underlying funds buy debt rated BBB/Baa or better at purchase. Income is paid out monthly.sec.gov
• What it owns matches what it says it owns, with the mix spread across government, corporate and securitized short paper.sec.gov

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.

• BLST The index giants cost a fraction: AGG and BND charge 0.03%. Here you pay an active manager for duration and sector calls on top of the ETFs they buy.sec.gov
• It launched in 2025, so there is only a short record to judge, and it is not one of the category's heavily traded names.
• Distributions can include return of capital, which hands back your own money rather than income the portfolio earned.
