BBLB vs XTWY

XTWYBBondBloxx Bloomberg Twenty Year Target Duration US Treasury ETF

In short

BBLB The same 20+ year Treasury index the category's household name tracks, at a fraction of the fee. A plain, cheap wrapper on the long end of the curve, still small and young by category standards.

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

BBLB The fund seeks investment results that closely correspond, before fees and expenses, to the ICE U.S. Treasury 20+ Year Bond Index.

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

• BBLB Costs 0.04% a year against a 0.15% median for long-Treasury funds, and follows the very same index as TLT, which charges 0.15%.
• No clever overlay. It holds the actual long-dated Treasuries of the ICE U.S. Treasury 20+ Year Bond Index, a few dozen bonds, and has hugged that benchmark closely.
• Coupon income is paid out monthly, not quarterly, so cash arrives on a steadier rhythm.
• On cost and index fidelity, one of the tidiest implementations in the long-Treasury group, alongside cheap rivals like VGLT and EDV.

• 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

• BBLB Trades thinly next to the category's giants, so spreads can widen. Limit orders do real work here.
• A small fund launched in 2023, without the asset base or history of the older names tracking the same ground.
• Bonds maturing 20+ years out swing hard when long yields move. Credit risk is about as low as it gets; interest-rate risk is not.

• 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.
