BKAG vs CRXP

BKAGABNY Mellon Core Bond ETF

CRXPCColumbia Core Plus 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.

CRXP Columbia's active answer to the Agg: a core bond portfolio with a permission slip, up to 20% high yield and up to 25% foreign debt, for 0.38% net of a waiver through July 31, 2027.

Stated mandate

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

CRXP The Fund seeks total return from current income and capital appreciation.

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.

• CRXP Core plus means leeway the plain Agg lacks: the prospectus allows up to 20% below investment grade and up to 25% foreign debt, including emerging markets.sec.gov
• 0.38% net of a waiver through July 31, 2027 (0.48% gross) sits near the category median, restrained for an actively run bond fund.
• Managers can dial interest rate and credit exposure using futures and swaps, including credit default swaps, for hedging and for investment.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.

• CRXP Index rivals cost a fraction: AGG, BND, SPAB and SCHZ each charge 0.03%. The manager's judgment is what the extra buys.
• The waiver runs only through July 31, 2027. Absent a renewal, the fee reverts toward the 0.48% gross.
• Launched in December 2025, so the record is short and volume runs well below the category's index giants, which can mean wider spreads.sec.gov
