TDTF vs VTP

TDTFBNorthern Trust iBoxx 5-Year Target Duration TIPS ETF

VTPAVanguard Total Inflation-Protected Securities ETF

In short

TDTF Most TIPS funds let their interest-rate sensitivity drift as bonds age. TDTF pins it: a monthly-rebalanced index built to hold modified adjusted duration near five years, for 0.18% net of a waiver through March 1, 2027.

VTP Vanguard's ETF answer for the whole TIPS curve. It tracks a market-value-weighted index of Treasury inflation-linked bonds with at least a year left to run, charges five basis points, and opened for business in 2025.

Stated mandate

TDTF The Fund seeks to track the price and yield performance of the iBoxx 5-Year Target Duration TIPS Index before fees and expenses.

VTP The Fund passively tracks the full market of U.S. Treasury inflation-protected public obligations through the ICE U.S. Treasury Inflation Linked Bond Index.

Why people hold it

• TDTF The index targets a modified adjusted duration of roughly five years and rebalances monthly, drawing from TIPS maturing in three to twenty years.sec.gov
• Hugging the index is the entire job here, and on that measure it has been one of the stronger implementations in the TIPS group.
• Listed in 2011 under Northern Trust's FlexShares brand, it is a multi-billion-dollar fund with moderate trading volume.
• The holdings are plain US Treasury TIPS, whose principal and interest payments are tied to an official inflation measure.sec.gov

• VTP Five basis points: under half the typical fund in its Treasury peer group, and well below the 0.12% charged by broad TIPS rival SPIP.
• Full-curve coverage. The index is market value weighted and takes inflation-protected Treasuries with at least one year to maturity, no upper limit, so no single maturity slice bet.ice.com
• Vanguard's other inflation-linked ETF stops below five years to maturity. This one is the long-end-included sibling, in the same low-cost index wrapper.vanguard.com
• The inflation link sits inside the bonds, not in a strategy overlay: principal and coupons are indexed to consumer prices, and the fund passes income through quarterly.vanguard.com

Worth knowing

• TDTF 0.18% net of a waiver through March 1, 2027 sits above the category median; broad peers SCHP and VTIP charge 0.03%, but let duration drift with their maturity buckets.
• Payments move with inflation accruals, so cash arrives on an irregular schedule rather than a steady monthly rhythm.sec.gov
• Targeting duration holds the dose of interest-rate risk steady, it does not remove it. Real-yield swings still show up in the price.sec.gov

• VTP Owning the long end cuts both ways. Real-rate moves hit a full-maturity TIPS portfolio harder than a sub-five-year one, so expect more price movement.ice.comvanguard.com
• A 2025 launch means a short track record and thinner trading than the long-established TIPS funds, which can show up as wider bid-ask spreads.
• Payouts move with inflation adjustments rather than a fixed rate, and Vanguard discloses that a distribution can include return of capital.vanguard.com
