DFIP vs STIP

DFIPBDimensional Inflation-Protected Securities ETF

STIPAiShares 0-5 Year TIPS Bond ETF

In short

DFIP Dimensional's TIPS vehicle: US inflation-linked Treasuries, one job, 0.11% a year. Priced a shade under the typical Treasury-bond ETF, though plain index TIPS funds go cheaper still.

STIP The short-fuse inflation hedge. STIP holds only inflation-linked Treasuries maturing inside five years, keeping the inflation link while sidestepping most of the long-bond rate swings. Three basis points a year.

Stated mandate

DFIP The fund seeks inflation protection and current income consistent with inflation-protected securities.

STIP The fund seeks to track an index of U.S. Treasury inflation-protected securities with maturities under five years, offering inflation hedging while managing duration risk.

Why people hold it

• DFIP One job, straight from its objective: inflation protection plus current income from inflation-protected securities. No credit detours.
• Charges 0.11% a year, just under the typical fund in its Treasury peer group.
• The portfolio stays close to what the objective promises, and the fund sits in the upper half of its Treasury cohort.
• Listed in 2021 and now a billion-dollar-plus fund, so this is no thin, untested ticker.

• STIP Three basis points a year, roughly a quarter of the typical fee in its Treasury ETF group. On cost, this is near the floor for bond funds.
• Maturities capped under five years by design, so the inflation adjustment stays and the long-duration price swings largely do not.
• Running since 2010, a multi-billion-dollar fund that trades actively. Plain index construction, US Treasuries only.
• Sits in the upper half of the Treasury bond ETFs we cover, one of the stronger short-maturity builds in that group.

Worth knowing

• DFIP Index-tracking TIPS exposure comes cheaper: SCHP charges 0.03% against 0.11% here. The gap buys Dimensional's version of the job.
• Payouts arrive on an irregular schedule, not a fixed monthly check.
• Volume is moderate rather than heavy for the category, so execution costs can matter more on large orders.

• STIP Short bonds accrue less inflation compensation than long-dated TIPS, and prices still move with real yields. This is a dampened hedge, not a pure one.
• Distributions are irregular. Payouts ride the inflation adjustment, so income arrives lumpy rather than as a steady check.
• Around 25 bonds, all at the front of the curve. SCHP spans the full TIPS maturity range for the same 0.03%.
