KCSH vs VUSB

KCSHBKraneShares Sustainable Ultra Short Duration Index ETF​

VUSBAVanguard Ultra-Short Bond ETF

In short

KCSH Most of this aisle is a Treasury-bill parking lot. KCSH is the climate-screened one: sub-one-year investment-grade corporate bonds filtered by ISS climate analysis for Paris Agreement alignment, with income paid monthly.

VUSB Vanguard's first actively managed bond ETF, run by its in-house fixed income team and priced at 0.10%. It holds investment-grade paper maturing inside two years: a step past a money fund, well short of a real bond fund.

Stated mandate

KCSH Seeks investment results that generally correspond to the price and yield performance of the Solactive ISS Sustainable Select 0-1 Year USD Corporate IG Index. The index covers U.S.-dollar investment-grade corporate debt maturing within one year and aligned with the Paris Agreement.

VUSB The fund seeks current income with limited price volatility while investing in diversified high- and medium-quality fixed-income securities. It expects to maintain a dollar-weighted average maturity of 0–2 years.

Why people hold it

• KCSH The differentiator is the screen: ISS climate analysis, Paris 1.5C-by-2050 alignment and fossil fuel exclusions, applied to ultra-short corporate credit.kraneshares.com
• The index targets credit and rate risk similar to mainstream ultra-short investment-grade benchmarks, so the screen reshapes the issuer list more than the risk profile.kraneshares.com
• Roughly 160 short-dated corporate bonds, held physically inside a 1940 Act fund, with distributions monthly rather than quarterly.kraneshares.com
• Fee sits near the category median at 0.20% net of a waiver through August 1, 2028, a long runway for a screened product in a price-war category.

• VUSB At 0.10%, it costs half the typical ultra-short bond ETF and undercuts the other leaders in the group: SHV, PULS, FLDR and DUSB all charge 0.15%.
• Active, not adventurous. The managers buy investment-grade bonds (A3-or-better high quality plus BBB-tier medium quality) and hold average maturity to zero-to-two years.vanguard.com
• Income lands monthly, sourced from roughly 170 bonds, so no single issuer drives the outcome.
• A multi-billion-dollar fund that trades actively, and the same portfolio team also runs a similar Vanguard ultra-short fund.vanguard.com

Worth knowing

• KCSH Bill funds are cheaper: VBIL 0.06%, CLIP 0.07%, ICSH 0.08%, no waivers. KCSH is 0.20% net of a waiver through August 1, 2028, and 0.30% gross if it lapses.
• This is corporate credit, not government paper. Investment-grade and under a year to maturity, but default and spread risk exist where a Treasury bill fund has effectively none.kraneshares.com
• Small and lightly traded next to the category's giants, and live only since 2024: spreads can be wider and the track record is short.

• VUSB This is not a money market fund. No fixed $1 share price, and the market price can trade above or below the value of the holdings.vanguard.com
• The mandate allows BBB-tier credit, a notch of risk a Treasury-only neighbor like SHV doesn't take.vanguard.com
• Bonds this short reprice with short-term rates, so the monthly payout drifts up and down instead of holding a set level.vanguard.com
