PBTP vs TDTT

PBTPAInvesco 0-5 Yr US TIPS ETF

TDTTBNorthern Trust iBoxx 3-Year Target Duration TIPS ETF

In short

PBTP Inflation-linked Treasuries with the long end cut off: PBTP holds only TIPS maturing inside five years, keeping the CPI adjustment while dialing down interest-rate swings.

TDTT TIPS duration wanders as inflation expectations shift. TDTT's index pins it, targeting a modified adjusted duration of 3.0 years and rebalancing monthly: inflation-linked Treasuries on a short leash.

Stated mandate

PBTP The fund provides exposure to US Treasury Inflation-Protected Securities with remaining maturities from one month to less than five years.

TDTT The Fund seeks to track, before fees and expenses, the price and yield performance of the iBoxx 3-Year Target Duration TIPS Index. It uses a passive indexing approach, generally replicating the index or using representative sampling when full replication is impracticable.

Why people hold it

• PBTP Costs 0.07% a year, under the 0.12% median for Treasury bond ETFs.
• Narrow by design: only TIPS with one month to under five years remaining, which leaves out the long-dated bonds that drive most price swings in broad TIPS funds.invesco.com
• Index-tracked and running at Invesco since 2017, with distributions paid quarterly.

• TDTT The index targets a modified adjusted duration of 3.0 years, resets when it strays past a 5% band, and rebalances monthly. Duration is the design, not a byproduct.flexshares.comflexshares.com 2
• Built from TIPS with one to ten years to maturity and at least $2 billion outstanding, so the sleeve leans on the biggest, most tradable issues.flexshares.comflexshares.com 2
• Listed in 2011 and now a multibillion-dollar fund from Northern Trust, long past the stage where a niche bond ETF is fighting for scale.

Worth knowing

• PBTP Thinly traded next to the big names in the aisle, so spreads can run wider and sizeable orders take more care.
• Broad TIPS funds such as SCHP charge 0.03% and cover the whole maturity ladder. Here you pay a bit more to skip the long end.
• Short maturities cut both ways: less real-yield duration means smaller moves when rates fall as well as when they rise.

• TDTT 0.18% net of a waiver through March 1, 2027 (0.19% gross), above the category median. Plain market-cap TIPS funds like SCHP and VTIP charge 0.03%.
• Pinning duration near three years is a middle setting: it moves less with rates than long TIPS, more than cash-like short TIPS.flexshares.com
• TIPS coupons move with CPI adjustments, so payouts land on an irregular schedule and vary in size rather than arriving as a steady check.flexshares.com
