BSTS provides targeted exposure to U.S. Treasury bonds maturing in 2028, functioning like a bond ladder in a single ETF. The fund will distribute all proceeds and liquidate in December 2028, offering predictable cash flow timing for liability matching or retirement planning.
How It Works
The fund holds a basket of Treasury bonds all maturing in 2028, maintaining constant duration that declines predictably each year. Unlike traditional bond funds that roll maturities forward, BSTS lets its duration naturally decay toward zero. The portfolio is equally weighted across the maturity year rather than market-cap weighted, providing balanced exposure to different Treasury issues.
Key Features
- Built-in maturity date eliminates reinvestment risk — you know exactly when you get your money back
- Duration declines predictably each year, reducing interest rate sensitivity as 2028 approaches
- Zero expense ratio makes this cheaper than building your own Treasury ladder through individual bonds
Risks
- Interest rate risk remains significant early in the fund's life — a 1% rate rise could mean 5-6% price decline
- No ability to extend maturity means missing out if rates fall and you want to lock in higher yields
- Liquidity may deteriorate as 2028 approaches and the fund shrinks, widening bid-ask spreads
Who Should Own This
Perfect for investors with a specific 2028 liability — college tuition, retirement spending, or debt repayment. Also works for conservative investors who want Treasury exposure but hate the uncertainty of perpetual bond funds. Think of it as a Treasury bond you can trade like a stock, without the $1,000 minimums or dealer markups of individual bonds.
