BKAG vs BNDX

BKAGABNY Mellon Core Bond ETF

BNDXAVanguard Total International 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.

BNDX The international half of a global bond portfolio with the currency risk stripped out. BNDX tracks investment-grade bonds from outside the US and hedges them back to dollars, so you get foreign rates and credit without the FX rollercoaster.

Stated mandate

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

BNDX Seeks to track a benchmark measuring the investment return of non-U.S.-dollar-denominated investment-grade bonds. It uses currency hedging and index sampling while maintaining broad exposure to major non-U.S. bond markets.

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.

• BNDX Hedges its foreign bond exposure back to US dollars, so results track overseas rates and credit rather than swings in the euro or yen.vanguard.com
• Charges 0.07% a year, near the floor for index bond funds, and covers the ex-US ground its stablemate BND leaves out.
• Running since 2013, one of the largest and most actively traded bond ETFs around, and it distributes monthly.
• Uses index sampling to hold a broad spread of investment-grade debt across the major non-US bond markets, one of the stronger builds in its peer group.vanguard.com

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.

• BNDX The hedge cuts both ways: it removes the lift from a falling dollar along with the drag from a rising one.
• Interest rates in Europe and Japan move this portfolio, and a currency hedge does nothing to soften that.
• No US bonds by mandate. It covers the ex-US slice of a bond allocation only.vanguard.com
