BIL vs ICSH

BILAState Street SPDR Bloomberg 1-3 Month T-Bill ETF

ICSHAiShares Ultra Short Duration Bond Active ETF

In short

BIL The original T-bill ETF, running since 2007: a giant, heavily traded stack of one-to-three-month Treasury bills that pays out monthly. Newer copycats undercut it on fee, but few match its trading footprint.

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.

Stated mandate

BIL The fund seeks to track the price and yield performance of the Bloomberg 1-3 Month U.S. Treasury Bill Index before fees and expenses. It provides exposure to publicly issued U.S. Treasury bills with maturities of one to three months.

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.

Why people hold it

• BIL Holds publicly issued US Treasury bills maturing in one to three months, so the credit is the US government and rate sensitivity is measured in weeks, not years.ssga.com
• A straight index job against the Bloomberg 1-3 Month U.S. Treasury Bill Index, tracked closely: no credit tiers, no duration calls, no moving parts to second-guess.
• One of the most actively traded funds in its category, with a multi-billion-dollar asset base behind it, so getting in and out is rarely the hard part.
• Pays monthly and has run this same narrow mandate since 2007, across zero-rate years and high-rate years alike.

• 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.

Worth knowing

• BIL The 0.14% fee is the trade-off. Rivals run near-identical bill exposure for less (VBIL at 0.06%, CLIP at 0.07%), and on T-bills the fee is most of the gap.
• Income moves with short-term Treasury rates. The monthly payout is whatever bills are yielding, so it rises and falls with them rather than sitting fixed.
• A few dozen bills, all maturing inside three months. That is a cash parking spot by design, with no mechanism for capital growth.

• 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.
