IGSB vs PRSD

IGSBAiShares 1-5 Year Investment Grade Corporate Bond ETF

PRSDDState Street Short Duration IG Public & Private Credit ETF

In short

IGSB Corporate credit with the rate risk dialed down: roughly 4,700 investment-grade bonds, none maturing past five years, for four basis points. iShares has run it since 2007.

PRSD Wall Street's public-private mashup on a short leash: an actively managed bond ETF that pairs investment-grade public debt with private credit while targeting a one- to three-year duration.

Stated mandate

IGSB The fund seeks to track an index containing U.S. dollar-denominated investment-grade corporate bonds with remaining maturities from one through five years.

PRSD The fund is actively managed and invests primarily in investment-grade debt securities, including public and private credit. It seeks to maintain a one- to three-year duration.

Why people hold it

• IGSB Four basis points a year, a fraction of the typical investment-grade corporate bond fund's fee and level with the cheapest tier of its peer group.
• One-to-five-year maturities mean prices move less when rates move than long-dated corporate funds. Same corporate credit, shorter leash.ishares.com
• Thousands of individual bonds tracking the ICE BofA 1-5 Year US Corporate Index, with income paid monthly.ishares.com
• Trading since 2007, actively traded, and one of the strongest builds in the investment-grade corporate group on cost, portfolio and execution.

• PRSD Private credit normally lives behind institutional minimums and lock-ups. Here it sits inside a daily-traded ETF, alongside public investment-grade bonds.statestreet.com
• The mandate targets a one- to three-year duration, which mechanically dials down interest-rate sensitivity compared with core bond funds reaching out a decade or more.ssga.com
• Active, but measurable: it runs against the Bloomberg US Aggregate 1-3 Year Bond Index and spreads risk across roughly 140 positions rather than a handful of bets.

Worth knowing

• IGSB Short maturities cut both ways: less price damage when rates rise, less lift when they fall.
• These are company bonds, not Treasuries. Investment grade, but credit spreads can widen and prices move with them.
• Only the front of the curve. Sibling IGIB runs 5-10 years and USIG spans broad maturities, both at the same fee.

• PRSD 0.45% a year is more than double the typical investment-grade corporate bond ETF's 0.19%, and index staples like VCIT and IGSB charge roughly 0.03% to 0.04%. That gap is the toll for the private sleeve.
• The private holdings don't change hands on an exchange, so part of the portfolio is marked off arranged bids and models instead of continuous public quotes.ssga.com
• It launched in September 2025, so there's no multi-year record showing how the public-versus-private mix behaves across a full credit cycle.statestreet.com
