IBIG vs VTIP

IBIGBiShares iBonds Oct 2030 Term TIPS ETF

VTIPAVanguard Short-Term Inflation-Protected Securities ETF

In short

IBIG Most target-maturity bond funds hand you a fixed nominal payout. IBIG fills the same dated slot with US Treasury inflation-protected bonds maturing in 2030, so the principal underneath moves with CPI. A ladder rung with an inflation clause.

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

IBIG The fund is designed to follow an index of U.S. Treasury inflation-protected securities that mature in 2030.

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

• IBIG The inflation-linked corner of a mostly nominal category: it follows the ICE 2030 Maturity US Inflation-Linked Treasury Index, so TIPS principal adjusts with CPI while the maturity year stays fixed.
• 0.10% a year, level with the median target-maturity bond fund, for a portfolio of US Treasury paper. No credit spread, no currency layer.
• Everything inside matures in the same year, so duration winds down as 2030 approaches and the fund stacks cleanly alongside other dated rungs such as IBTJ or BSCU.

• 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

• IBIG Thinly traded and small next to the nominal iBonds funds. The bid-ask spread is part of what you pay, especially in size.
• Only a handful of TIPS mature in any single year, so this is a short list of bonds, not a broad index.
• Payouts arrive quarterly and ride on inflation adjustments, so they are uneven. When inflation runs cool, nominal Treasuries of the same maturity can out-yield TIPS.

• 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.
