BBBL vs IGLB

BBBLCBondBloxx BBB Rated 10+ Year Corporate Bond ETF

IGLBAiShares 10+ Year Investment Grade Corporate Bond ETF

In short

BBBL Most corporate bond funds hand you the entire ratings ladder. BBBL takes one rung and one maturity band: BBB-rated corporate paper maturing in 10 years or more. A single-cell tool for people who want to set credit and duration themselves.

IGLB The long end of the iShares corporate ladder: only investment-grade company bonds with more than ten years left to run. Interest-rate sensitivity isn't a side effect here, it's the design.

Stated mandate

BBBL The Fund seeks to track the Bloomberg US Corporate BBB 10+ Year Index before fees and expenses. The index covers BBB-rated, fixed-rate, taxable, U.S. dollar-denominated corporate bonds with remaining maturities of at least ten years.

IGLB The fund seeks to track an index of U.S. dollar-denominated investment-grade corporate bonds with remaining maturities longer than ten years. It provides exposure to long-duration, high-quality corporate credit and seeks income.

Why people hold it

• BBBL Pure slice, no blending: BBB-rated, fixed-rate, dollar-denominated corporate bonds with at least ten years left to run. The label and the portfolio say the same thing.
• 0.19% a year sits right at the median for investment-grade corporate ETFs, so the narrow mandate does not carry a specialist markup.
• Distributions land monthly, matching how most household bills arrive rather than a quarterly drip.

• IGLB Fee is 0.04% a year, a sliver of what the typical investment-grade corporate bond fund charges.
• Roughly 3,800 bonds in one ticker, with income paid out monthly rather than quarterly.
• The 10+ slice of a maturity-cut iShares lineup (IGSB 1-5, IGIB 5-10), so duration is chosen by picking a slice instead of blending funds.
• Tracks the ICE BofA 10+ Year US Corporate Index closely and trades actively, putting it among the stronger builds in a crowded corporate bond field.

Worth knowing

• BBBL Ten-year-plus maturities are the sharp end of rate sensitivity. Price moves per rate shift are far larger here than in short or intermediate corporate funds.
• BBB is the bottom rung of investment grade, one notch above high yield, so downgrade risk sits closer than in AA or A portfolios.
• Small and lightly traded next to broad corporate giants like VCIT and IGIB, which also charge a few basis points. Spreads can be wider on this one.

• IGLB Ten-years-and-out maturities mean the sharpest price swings in investment-grade corporates when yields move. Duration is the feature and the risk.
• Company bonds, not Treasuries: prices react to credit spreads as well as rates, and investment grade still carries downgrade risk.
• No short-maturity ballast by design, so nothing inside the fund steadies the ride when the long end sells off.
