ICSH vs VUSI

ICSHAiShares Ultra Short Duration Bond Active ETF

VUSICVoya Ultra Short Income ETF

In short

ICSH BlackRock's active cash-parking sleeve, live since 2013: roughly 250 ultra-short investment-grade bonds and money market instruments, run for current income with preservation of capital, at 0.08% a year.

VUSI Voya's late-2025 arrival in the cash-parking aisle: an actively managed ultra-short bond fund built to hunt current income while keeping principal steady. A new name in a category ruled by entrenched giants.

Stated mandate

ICSH The fund seeks current income consistent with preservation of capital through actively managed exposure to ultra-short-term investment-grade bonds and money market instruments.

VUSI VUSI seeks high current income while preserving capital. It is actively managed and normally invests at least 80% of its assets in diversified income-producing bonds or economically similar derivatives.

Why people hold it

• ICSH At 0.08% a year it undercuts the typical cash-alternative ETF, which charges about 0.20%, and comes in below top-rated rivals like FLUD and JPST.
• Actively managed rather than a fixed ladder: the team picks across ultra-short investment-grade bonds and money market instruments, spread over roughly 250 positions.ishares.com
• Trading since 2013 and now a multi-billion-dollar fund that changes hands actively, giving it one of the longer records in the cash-alternative aisle.
• Sits in the top quartile of its cash-alternative peer group, helped by high-quality holdings and low cost.

• VUSI Actively managed, not index-shackled: at least 80% of assets sit in diversified income-producing bonds or economically similar derivatives, with a stated goal of high current income while preserving capital.
• The prospectus sets a monthly income distribution schedule, which matches how most people use a cash-adjacent holding.
• The mandate isn't fenced to US paper. It can reach into international and emerging market issuers, a wider pool of short-dated bonds than a Treasury-only fund shops from.
• Ordinary 1940 Act fund plumbing. No partnership wrapper, no K-1 arriving in your mailbox in March.

Worth knowing

• ICSH Not a money market fund. The share price floats, and preservation of capital is the stated aim, not a promise.ishares.com
• It holds investment-grade corporate paper alongside money market instruments, so it carries credit risk a Treasury-bill-only fund does not.ishares.com
• It pays monthly, but the amount rides short-term rates, and as an active fund its results can drift from its 6-month T-bill reference index either way.

• VUSI Active costs more here: 0.25% a year against a category median of 0.20%, and above the aisle's scale players (VUSB at 0.10%, SHV and PULS at 0.15%).
• Launched in November 2025, so there's no long record to judge and the fund is still building scale. Newer, smaller funds tend to trade with wider bid-ask spreads than category veterans.stockanalysis.com
• Ultra-short is not the same as cash. This holds bonds, and the mandate allows derivatives and non-US credit, so the share price can move.
