BIV vs BKAG

BIVAVanguard Intermediate-Term Bond ETF

BKAGABNY Mellon Core Bond ETF

In short

BIV Most bond funds hand you the entire market. BIV picks a lane: investment-grade U.S. government and corporate bonds in the 5-to-10-year band, sampled by Vanguard, priced at three basis points.

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.

Stated mandate

BIV The fund seeks to track a market-weighted bond index representing the intermediate-term investment-grade U.S. bond market. It uses index sampling and normally invests at least 80% of assets in securities represented by the index.

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

Why people hold it

• BIV 0.03% a year against a category median around 0.36%. In bonds, where returns are mostly coupon math, cost is one of the few levers you fully control.
• You pick the maturity band instead of inheriting it. The benchmark is a 5-10 year government/credit index: no mortgage pools, no 30-year tail dragging the duration around.vanguard.com
• Running since 2007 and among the closest index trackers in its peer group, with the trading depth that comes from a multi-billion-dollar asset base.
• Pays income monthly and spreads it across roughly 300 investment-grade bonds, so no single issuer carries the paycheck.

• 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.

Worth knowing

• BIV Intermediate duration cuts both ways. A 5-10 year portfolio reprices harder when yields move than a short-term fund does. Rate sensitivity is the main risk you are taking here.
• This is a slice, not the whole bond market. Aggregate funds at the same 0.03% (BND, SPAB, SCHZ) also carry mortgage-backed and short and long maturities that BIV leaves out.
• Investment-grade only, U.S. only. No high-yield sleeve and no foreign bonds, which is the point of the design but caps what the income stream can come from.

• 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.
