In short

BBBI Most investment grade bond funds blend AAA down to BBB. BBBI keeps only the BBB rung, the bottom tier of investment grade, and only bonds maturing in five to ten years. Precision slicing from a bond-only shop, at 0.19%.

SPIB The middle of the corporate bond curve in one ticker: investment-grade company debt maturing in one to ten years, thousands of issues deep, for 0.04% a year. Trading since 2009.

Stated mandate

BBBI The Fund seeks to track an index of BBB-rated, fixed-rate, taxable U.S.-dollar corporate bonds from U.S. and non-U.S. issuers with remaining maturities of at least five and less than ten years.

SPIB The fund seeks to track the Bloomberg Intermediate US Corporate Index and provide exposure to U.S. corporate bonds with maturities of at least 1 year and less than 10 years.

Why people hold it

• BBBI Holds only BBB-rated corporate bonds maturing in five to ten years. One rating rung, one maturity band, rather than an AAA-through-BBB blend.
• One of three BondBloxx ETFs that split BBB credit into 1-5, 5-10 and 10+ year buckets, so the maturity band is a choice instead of a package deal.prnewswire.com
• The 0.19% fee sits mid-pack among investment grade corporate bond ETFs, so the narrower screen doesn't come with a specialty markup.
• Literal mandate: a named Bloomberg index, a stated rating, a stated maturity range, income paid monthly. Little room for the portfolio to wander.

• SPIB 0.04% a year sits at the floor of the investment-grade corporate group, a hair off the cheapest name in the top tier (VCIT, 0.03%).
• One fund covers the whole 1-to-10-year span. iShares splits that same range across two tickers (IGSB for 1-5 years, IGIB for 5-10).
• Roughly 5,000 bonds spread single-issuer risk thin, and the fund has tracked its Bloomberg corporate benchmark closely.
• Heavily traded, pays monthly, and rates as one of the stronger implementations in the investment-grade corporate peer group.

Worth knowing

• BBBI BBB is the bottom rung of investment grade, one notch above high yield, so downgrade and credit risk run higher here than in an AAA-heavy blend.
• Costs more than broad intermediate investment grade funds like IGIB and VCIT (0.03% to 0.04%). That gap is the toll for the BBB-only screen.
• Launched in 2024 and thinly traded next to the category giants, so the spread and a limit order deserve a glance before you hit the button.

• SPIB Pure corporate credit. No Treasuries or agency paper in the mix to cushion a widening in company spreads.
• Intermediate maturities move more on rate swings than a short-dated corporate fund such as IGSB.
• The monthly payout floats with market yields and the bonds the index holds. It is not a fixed amount.
