IUSB vs TABD

IUSBAiShares Core Universal USD Bond ETF

TABDCTransamerica Bond Active ETF

In short

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.

TABD Transamerica's first move into ETFs: an actively run core bond portfolio steered by Aegon's fixed income desk, aiming for total return from income plus price gains, at 0.39% a year.

Stated mandate

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

TABD The Fund seeks total return from current income and capital appreciation.

Why people hold it

• 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.

• TABD Active bond management for 0.39% a year, only a few basis points above the median fee in a cohort dominated by cheap index trackers.
• Run by Aegon Asset Management, Transamerica's affiliated bond shop, and launched December 2025 as one of the firm's first two active ETFs.prnewswire.comtransamerica.com
• Clear mandate: total return from current income and capital appreciation, principally through bonds and bond-like derivatives. No index to track.

Worth knowing

• 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.

• TABD Index heavyweights BND, SPAB and SCHZ charge 0.03%. Here you pay roughly ten times that for a manager's discretion.
• Launched in December 2025, so there is no long record to judge. Results ride on the subadviser's calls, not an index.
• Small and lightly traded next to the category's giants, so bid-ask spreads can run wider than on the mega funds.
