ICPI vs VTIP

ICPI—iShares 0-1 Year TIPS Bond ETF

VTIPAVanguard Short-Term Inflation-Protected Securities ETF

In short

ICPI Most of the T-bill aisle pays a nominal yield and hopes inflation behaves. ICPI holds the shortest inflation-protected Treasuries on the curve, one year or less, so principal moves with CPI while rate risk stays small.

VTIP Inflation protection without the long-bond whiplash. VTIP holds only Treasury TIPS maturing inside five years, so CPI does most of the driving and rate swings do less of it, for three basis points a year.

Stated mandate

ICPI The fund seeks to track an index of inflation-protected U.S. Treasury bonds with remaining maturities of one year or less. It is designed to provide a way to seek protection against near-term inflation.

VTIP Tracks a benchmark measuring the investment return of U.S. Treasury inflation-protected public obligations with remaining maturities under five years.

Why people hold it

• ICPI Rare mandate in a bill-fund crowd: inflation-protected U.S. Treasuries maturing in a year or less, so principal adjusts with CPI while interest-rate sensitivity stays short.ishares.com
• 0.09% expense ratio, below the median for its short-Treasury peer group.
• One job, done literally: track an index of sub-one-year TIPS, U.S. Treasury credit only, no active tinkering. Distributions land quarterly.

• VTIP Three basis points a year, against a 0.12% median for Treasury bond ETFs in its group. Vanguard's at-cost setup shows up right in the fee line.vanguard.com
• TIPS principal ratchets with CPI, and the under-five-year maturity cap keeps duration short, so rate moves land lighter here than in full-curve TIPS funds like SCHP.vanguard.com
• Open since 2012 and now a multi-billion-dollar, actively traded fund that owns Treasury paper directly. Plain index rules, no swaps, no credit detours.

Worth knowing

• ICPI A late-2025 launch with a small asset base and light trading, so bid-ask spreads can run wider than the household-name bill funds. Limit orders matter here.
• This is a CPI-linked instrument, not a yield engine. With a year or less to maturity, the inflation adjustment does most of the work, in both directions.
• Plain nominal peers like BIL and TBLL are far more heavily traded for straight cash parking. ICPI's differentiator is the inflation link, not liquidity.

• VTIP Short maturities cut both ways: less sensitivity to rates, and less exposure to shifts in long-run inflation expectations than a full-maturity TIPS fund such as SCHP.
• Income rides on CPI accruals, so the quarterly payout moves around rather than arriving as a steady coupon.
• This is one narrow slice of one market, short US Treasury TIPS, not a diversified bond portfolio.
