SPBO vs USIG

SPBOAState Street SPDR Portfolio Corporate Bond ETF

USIGAiShares Broad USD Investment Grade Corporate Bond ETF

In short

SPBO The whole investment-grade corporate bond market in one ticker for three basis points. Most rivals sell you a maturity slice; SPBO owns the lot, and it undercuts other funds tracking the very same Bloomberg index.

USIG Most investment-grade corporate bond funds hand you one slice of the maturity curve. USIG takes the whole thing, thousands of US dollar corporate bonds from short-dated to long, for four basis points a year.

Stated mandate

SPBO The fund seeks investment results that generally correspond, before fees and expenses, to the price and yield performance of the Bloomberg U.S. Corporate Bond Index.

USIG The fund seeks to track an index of U.S. dollar-denominated investment-grade corporate bonds.

Why people hold it

• SPBO 0.03% a year against a category median of 0.19%. In bond land, where the yield does the heavy lifting, that fee gap is not a rounding error.
• Thousands of corporate bonds across the full maturity range, so you hold the broad IG corporate market instead of one duration bucket.ssga.com
• Same index, very different tolls: KORP charges 0.29%, JLQD 0.35%, JHCB 0.53%. SPBO sits at the cheap end of that list.
• Running since 2011, pays monthly, and tracks its benchmark about as closely as anything in the investment-grade corporate group.

• USIG Costs 0.04% a year, against a category median near 0.19%. CORP, which tracks the same ICE BofA US Corporate Index, charges 0.41%.
• One ticker, the full USD investment-grade corporate curve: thousands of bonds, short to long. Slice funds like IGSB (1-5 year) and IGIB (5-10 year) each cover one segment.ishares.com
• Running since 2007, it has tracked its index with very little drift and is one of the more actively traded funds in its category.
• Interest lands monthly, and this is a multi-billion-dollar fund that ranks among the strongest implementations in its peer group.

Worth knowing

• SPBO Full maturity range means long-dated paper is in the mix, so the price moves more when rates move than short-maturity peers like IGSB or SPIB.
• Corporate credit only. No Treasuries or mortgages to lean on, so the fund rides the health of corporate borrowers as well as the rate cycle.ssga.com
• Investment grade by design, US issuers only. No high-yield or emerging-market bonds in the basket.

• USIG Owning the whole curve means long-dated bonds ride along, so the price swings more when rates move than a short-maturity slice such as IGSB.
• This is corporate credit, not Treasuries. Investment grade at purchase, but prices can fall when spreads widen or an issuer is downgraded.ishares.com
• VCIT edges it on fee at 0.03%, though that fund stays in intermediate maturities rather than the full curve.
