CGCB vs IUSB

CGCBACapital Group Core Bond ETF

IUSBAiShares Core Universal USD Bond ETF

In short

CGCB Capital Group's core bond ETF uses the Bloomberg US Aggregate as a yardstick rather than a blueprint, and charges 0.27% to do it. The mandate is the unglamorous job bonds get hired for: diversification and capital preservation.

IUSB Most core bond funds stop at investment grade. IUSB keeps going, folding high-yield USD debt into the same wrapper across roughly 18,000 bonds, for 0.06% a year.

Stated mandate

CGCB The fund seeks to provide the diversification and capital-preservation benefits associated with core bonds.

IUSB The Fund seeks to track an index of U.S.-dollar-denominated bonds spanning investment-grade and high-yield sectors.

Why people hold it

• CGCB At 0.27%, it undercuts the core-bond median of 0.36% and most rivals measured against the same index: JCPB 0.37%, JFLX 0.45%, BOND 0.56%.
• Roughly 600 bonds behind one stated job: the diversification and capital-preservation benefits of core bonds. Income lands monthly.capitalgroup.com
• Portfolio stays tightly aligned with what the prospectus describes, one of the stronger implementations in the core bond group.
• Multi-billion-dollar fund that trades actively, notable for a product that only launched in 2023.

• IUSB 0.06% a year, a fraction of what the typical broad bond fund in its category charges, and iShares has run it since 2014.
• Roughly 18,000 bonds spanning investment-grade and high-yield sectors, so one ticker covers ground a plain Agg tracker leaves on the table.ishares.com
• Tracks its index closely, trades heavily, and sits on a multi-billion-dollar asset base. Income is paid monthly.
• Among the strongest implementations in a crowded field of nearly 200 core bond funds.

Worth knowing

• CGCB Plain trackers of the same index run 0.03% (BND, SPAB, SCHZ). You are paying up for security selection instead of a copy of the benchmark.
• Core bonds still move with interest rates and credit conditions. Capital preservation is the stated aim, not a floor under the price.
• Launched in 2023, so its history is shorter than most core bond ETFs sitting next to it.

• IUSB That high-yield sleeve is the trade-off: more credit risk than an investment-grade-only fund, and more movement when spreads widen.
• BND, SPAB and SCHZ charge 0.03%, half IUSB's fee, but they stay inside investment grade.
• Payouts land monthly, but the amount floats with the coupons underneath. Nothing about the income stream is fixed.
