BKAG vs BNDP

BKAGABNY Mellon Core Bond ETF

BNDPAVanguard Core-Plus Bond Index 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.

BNDP The Agg with the leftovers added back. BNDP indexes a broad sweep of US dollar taxable bonds spanning investment-grade and high-yield, in a passive Vanguard wrapper priced at 0.05%.

Stated mandate

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

BNDP The fund seeks to track the Bloomberg U.S. Universal Float Adjusted Index, which consists of U.S. dollar-denominated taxable bonds rated as either investment-grade or high-yield.

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.

• BNDP 0.05% a year, a fraction of what the typical fund in its bond category charges. In bonds, fee drag is the piece you actually control.
• The index reaches past the plain Agg: US dollar taxable bonds across both investment-grade and high-yield, so credit corners a core-only tracker skips come along.vanguard.com
• Rules-based, not manager discretion: it follows the Bloomberg U.S. Universal Float Adjusted Index, so the credit mix is disclosed by the index, not a quarterly judgment call.
• Cheaper than IUSB, the long-standing universal-index fund, at 0.05% versus 0.06%.

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.

• BNDP It listed in December 2025 and is still a small fund that trades lightly, so spreads can run wider than in the category's household names.
• The high-yield slice brings credit risk a pure investment-grade Agg tracker does not carry, and it tends to show up when credit markets wobble.
• Bare-bones Agg trackers like BND, SPAB and SCHZ charge 0.03%. The wider bond universe here costs a couple of basis points more.
