Defined-maturity bond ETFs sit in an odd corner of the fixed income world. They trade like ETFs, but they terminate on a fixed date and return cash to holders, behaving more like a single bond than a perpetual fund. Three of them stand out for investors trying to pin down yields for the rest of the decade: iShares iBonds Dec 2026 Term Corporate ETF (NYSEARCA:IBDR), Invesco BulletShares 2028 Corporate Bond ETF (NASDAQ:BSCS), and iShares iBonds Dec 2031 Term Treasury ETF (NASDAQ:IBTL).
None of these funds are household names. Together they let an investor build a ladder from late 2026 out to the end of the decade, capturing yields that in longer maturities sit near 5.25% on the Treasury curve. The Federal Funds upper bound is 3.75%, and the national average 12-month CD sits at 1.68%, which frames why locking in a bond ladder now carries appeal.
Why Defined Maturity Changes the Math
A conventional bond ETF never matures. Rising rates can dent its price permanently, and the yield an investor sees today drifts as the manager buys and sells to keep duration constant. A defined-maturity fund holds bonds that all come due in the same calendar year, then liquidates and distributes the remaining cash. The yield-to-maturity quoted at purchase is roughly what an investor collects if the fund is held to term, minus expenses and any defaults. The construct removes the guesswork about where rates go next.
The current backdrop matters for the yield story. The 10-year Treasury yield is 4.72%, sitting in the 99th percentile of its 12-month range. The 5-year sits at 4.39%, and the 20-year at 5.25%. Investment-grade corporate spreads add roughly a point on top, which is how defined-maturity corporate funds get to a 5-handle yield-to-maturity without stretching into junk credit.
IBDR: The Near-Term Anchor for a Bond Ladder
The shortest rung on this ladder is IBDR. Combined assets sit near $3.39 billion. The fund holds investment-grade corporate bonds, all maturing in December 2026, then unwinds and returns cash to shareholders. It carries a distribution yield near 4.09% against an expense ratio of 0.10%, and the portfolio spans more than 500 debt positions across financials, tech, healthcare, and energy issuers.
The largest debt positions include Microsoft, Oracle, IBM, Goldman Sachs, JPMorgan Chase, and Citigroup, with roughly 8% parked in a BlackRock cash sweep as bonds mature and roll off. The share price has traded in a tight band, gaining about 2% year to date and roughly 4% over the past year, consistent with a fund nearing its terminal date.
The trade-off is a short duration. IBDR delivers certainty and cash back within roughly a year, but it will not carry today’s yield forward through the decade. It serves as the earliest maturity in a laddered position or as a parking spot for capital slated for redeployment in late 2026.
BSCS: Mid-Ladder Corporate Yield Through 2028
The same idea extended two years further is BSCS. The Invesco BulletShares vehicle holds investment-grade corporate bonds maturing in 2028 and terminates in December, with structure and termination details confirmed in the fund’s prospectus. Monthly distributions in 2026 have run around $0.075 per share, and the expense ratio matches IBDR at 0.10%. Assets total $3.56 billion, with average daily volume near 480,918 shares, providing the fund with working liquidity for retail-scale trades.
The extra two years of duration is where the yield story sharpens. A 2028-maturity corporate ladder captures roughly the 3-year point on the yield curve, currently 4.27% in Treasuries, plus a spread that pushes the effective yield-to-maturity toward the 5% neighborhood referenced in the article’s premise. Shares closed near $20, up 1% year to date and 4% over the past year.
Credit risk is the main tradeoff. BSCS holds investment-grade issuers, but a recession that widens spreads before 2028 would pressure NAV even if the terminal payout is intact. Investors accept mark-to-market volatility in exchange for the corporate spread.
IBTL: The Overlooked 2031 Treasury Rung
The least discussed of the three and the most distinct in construction is IBTL. Rather than corporate credit, the fund tracks the ICE 2031 Maturity US Treasury index and terminates in December 2031. The portfolio is 99% U.S. Treasury securities across a laddered set of coupon issues, with a small cash sleeve. The expense ratio is 0.07%, the lowest of the three.
Assets under management are $650.53 million against 33.70 million shares outstanding, and monthly dividends have run around $0.066 per share. The five-year price return is negative at -7%, a reminder that Treasury duration lost value as yields rose from pandemic lows. That same duration is now the appeal: buying today captures the higher coupons the fund has accumulated, and holding to term retires the mark-to-market question.
The contrarian pick on this list is IBTL. It gives up the corporate spread that boosts yield on IBDR and BSCS, though it eliminates credit risk entirely. For a taxable investor, Treasury income is also exempt from state and local tax, which raises the after-tax yield above the headline number in high-tax states.
Choosing Between the Three
The three funds solve different problems. IBDR suits an investor seeking a cash-like landing spot with a defined redemption in late 2026, useful for near-term liabilities. BSCS carries the highest running yield of the group and suits investors comfortable holding investment-grade credit through 2028. IBTL is the choice for investors who want the longest lock, prioritize credit safety, and value the state-tax treatment of Treasury income.
Built as a ladder, the three overlap into a rolling structure that returns principal in 2026, 2028, and 2031, letting the investor reinvest each tranche at whatever rates prevail on those dates. The 2030 promise in the title is an approximation. What these funds actually deliver is a way to convert the current yield curve into a schedule of known cash returns without picking individual bonds.
