Our read on IBGB
CThe far end of the iBonds ladder: one ticker for Treasuries maturing in 2045, with a defined term date instead of an open-ended bond fund. Costs 0.07% a year and pays monthly.
The fund seeks to track an index of U.S. Treasury bonds maturing in 2045 and is designed to provide income and stability, support bond-ladder construction, and manage interest-rate risk through a defined maturity.
Why people hold it
- At 0.07%, it undercuts the typical target-maturity bond fund, where the cohort median sits at 0.10%.ishares.com
- One ticker covers a single year's worth of Treasury maturities, so a 2045 rung slots into a bond ladder without hand-picking individual bonds.ishares.com
- Tracks an index of US Treasury bonds, so there is no corporate credit to underwrite. Distributions are paid monthly.ishares.com
- Stands in the upper half of a crowded target-maturity peer group, and tracks its stated index closely.
Worth knowing
- A 2045 maturity means long duration: prices can swing hard with interest rates in the years before the term date.
- Launched in 2025 and still small and thinly traded, so spreads can run wider than on the ladder's short, heavily traded rungs like IBTJ.
- All Treasury, no corporates: the flip side of skipping credit risk is skipping credit spreads that corporate rungs (IBDU, BSCT) carry.
