CRXP vs IUSB

CRXPCColumbia Core Plus Bond ETF

IUSBAiShares Core Universal USD Bond ETF

In short

CRXP Columbia's active answer to the Agg: a core bond portfolio with a permission slip, up to 20% high yield and up to 25% foreign debt, for 0.38% net of a waiver through July 31, 2027.

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

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

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

• CRXP Core plus means leeway the plain Agg lacks: the prospectus allows up to 20% below investment grade and up to 25% foreign debt, including emerging markets.sec.gov
• 0.38% net of a waiver through July 31, 2027 (0.48% gross) sits near the category median, restrained for an actively run bond fund.
• Managers can dial interest rate and credit exposure using futures and swaps, including credit default swaps, for hedging and for investment.sec.gov

• 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

• CRXP Index rivals cost a fraction: AGG, BND, SPAB and SCHZ each charge 0.03%. The manager's judgment is what the extra buys.
• The waiver runs only through July 31, 2027. Absent a renewal, the fee reverts toward the 0.48% gross.
• Launched in December 2025, so the record is short and volume runs well below the category's index giants, which can mean wider spreads.sec.gov

• 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.
