BIL vs SHV

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

SHVAiShares Trust iShares 0-1 Year Treasury Bond 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.

SHV iShares' T-bill parking spot since 2007: nothing but US Treasuries maturing inside a year, rolled continuously, with income paid monthly. No corporate credit, no duration bets, 0.15% 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.

SHV The fund seeks to track an index composed of U.S. Treasury bonds with remaining maturities of one year or less.

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.

• SHV Treasuries only, by mandate. The index it tracks holds US government debt maturing in a year or less, so no corporate credit enters the portfolio.ishares.com
• 0.15% a year, below the typical ultra-short bond fund, from a multi-billion-dollar fund that has been running since 2007.
• One of the more heavily traded names in the ultra-short space, and it has hugged its benchmark closely, which matters when the whole return is T-bill yield.
• Income arrives monthly rather than quarterly.

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.

• SHV Payouts float with T-bill rates. Holdings mature and reroll within a year, so income resets quickly in both directions.
• Cheaper exists: Vanguard's VUSB charges 0.10% among the top-ranked ultra-short peers.
• This is the quiet corner of the bond market. By design there is no credit spread pickup and almost no interest-rate exposure to work with.
