EDV vs XTWY

EDVAVanguard Extended Duration Treasury ETF

XTWYBBondBloxx Bloomberg Twenty Year Target Duration US Treasury ETF

In short

EDV Zero-coupon Treasury STRIPS maturing in 20 to 30 years: the most rate-sensitive corner of the government bond market, in a five-basis-point Vanguard wrapper. Pure duration, nothing else.

XTWY Most long Treasury funds sort bonds by maturity and let duration drift. XTWY aims at a constant 20-year duration, rebalanced monthly, so the interest-rate dial stays where you set it.

Stated mandate

EDV The fund passively tracks an index of extended-duration, zero-coupon U.S. Treasury securities, specifically Treasury STRIPS with maturities from 20 to 30 years.

XTWY The fund seeks to track an index of U.S. Treasury securities whose duration ranges from 18 to 22 years.

Why people hold it

• EDV At 0.05%, it undercuts the typical long-Treasury ETF (cohort median 0.15%) and charges a third of what TLT does.
• STRIPS have their coupons removed, so the roughly 80 holdings are pure principal claims dated 20 to 30 years out. Rate sensitivity runs beyond standard 20+ year Treasury funds.vanguard.com
• Vanguard has run it since 2007, it tracks its Bloomberg STRIPS index closely, and it sits among the top-rated names in its long-Treasury peer group.

• XTWY The index straddles a 20-year duration target and the portfolio rebalances monthly, so rate sensitivity is held near a set level instead of sliding as bonds age.sec.govbondbloxxetf.com
• At 0.13% a year it undercuts the typical long-Treasury fund in its group, and it pays monthly.
• Toolkit piece, not a one-off: the long end of a target-duration Treasury lineup that steps from six months out to twenty years.bondbloxxetf.com
• Nothing exotic under the hood: US Treasury notes, bonds and principal-only STRIPS in a standard 1940-Act ETF, live since 2022.sec.gov

Worth knowing

• EDV Vanguard's own fact sheet warns that interest rate risk is expected to be extremely high and that rising rates may cause the fund's value to decline significantly.vanguard.com
• Vanguard describes the fund as primarily intended for pension plans and other institutions matching long-term liabilities.vanguard.com
• The STRIPS pay no coupons. Income accrues as the discount pulls toward par, and the fund passes that along to shareholders.vanguard.com

• XTWY Twenty years of duration cuts both ways. Price swings when yields move are large by design, and pinning duration means that sensitivity does not fade over time.sec.gov
• Cheap for the group, not the cheapest: VGLT (0.03%) and BBLB (0.04%) charge a fraction of it for maturity-bucket long Treasury exposure.
• A smaller, moderately traded fund next to giants like TLT, so trading costs deserve a look before sizing a position.
