BLST vs SCHZ

BLSTBBluemonte Short Term Bond ETF

SCHZASchwab U.S. Aggregate Bond ETF

In short

BLST One ticket, an actively managed basket of short-duration bond ETFs: Treasuries, corporates, TIPS and securitized debt, with a four-year average maturity ceiling written into the prospectus. Rate risk kept on a short leash.

SCHZ Schwab's core bond holding: the broad U.S. investment-grade bond market, over 10,000 issues deep, for 0.03% a year. That is the floor of a category whose median fee is more than ten times higher. Running since 2011, pays monthly.

Stated mandate

BLST The Fund seeks total return and income. It is actively managed and obtains at least 80% bond exposure, primarily through underlying funds holding short-duration debt securities.

SCHZ The fund seeks to track the total return of an index representing the broad U.S. investment-grade bond market.

Why people hold it

• BLST The maturity leash is in the prospectus: underlying funds hold debt averaging no more than four years, five years max. Far less rate whiplash than a total bond index.sec.gov
• All-in cost is 0.22% net of a waiver through August 31, 2027 (0.27% gross), and that figure already includes the 0.02% the underlying ETFs charge. Below the category median.sec.gov
• Investment grade is the floor: underlying funds buy debt rated BBB/Baa or better at purchase. Income is paid out monthly.sec.gov
• What it owns matches what it says it owns, with the mix spread across government, corporate and securitized short paper.sec.gov

• SCHZ 0.03% a year sits at the category floor, against a cohort median of 0.36%. Only a short list of aggregate-bond funds matches it, including AGG, BND and SPAB.
• Tracks the Bloomberg US Aggregate Bond Index tightly, one of the cleanest index implementations among the 187 funds in its peer group.schwabassetmanagement.com
• One ticker, thousands of investment-grade U.S. bonds, income paid monthly. The plumbing of a bond portfolio without buying a single bond yourself.
• Live since 2011 and now a multi-billion-dollar fund that trades actively, so trading costs on ordinary retail-sized orders tend to be minor.

Worth knowing

• BLST The index giants cost a fraction: AGG and BND charge 0.03%. Here you pay an active manager for duration and sector calls on top of the ETFs they buy.sec.gov
• It launched in 2025, so there is only a short record to judge, and it is not one of the category's heavily traded names.
• Distributions can include return of capital, which hands back your own money rather than income the portfolio earned.

• SCHZ This is duration exposure, not a cash substitute. Interest-rate moves, not credit selection, drive most of the ride, and that is the weakest part of its risk profile.
• Investment grade and U.S. only: no high-yield, no foreign bonds. Funds like BNDX cover the international side of the cohort.
• The aggregate-bond aisle is commoditized. Against AGG, BND and SPAB at the same 0.03%, the differences come down to index variant and where you already custody, not fee.
