Treasury ladders vs bond funds

You can own Treasuries two ways: buy a bond fund that holds hundreds of them, or buy individual Treasuries yourself and 'ladder' the maturities. Underneath, the assets are identical — the same government paper. The difference is entirely in the wrapper: cash flow certainty, convenience, and how each behaves when rates move.

What a ladder is

A ladder splits money across staggered maturities. A five-year, $50,000 ladder puts $10,000 each into Treasuries maturing in 1, 2, 3, 4, and 5 years. Each year a rung matures and returns face value; you either spend it or buy a new 5-year at the far end. The result: predictable cash arriving on known dates, and constant reinvestment at current rates.

The key difference: a maturity date, or not

An individual Treasury held to maturity pays exactly its face value on a known date — interim price swings are noise you can ignore. A bond fund never matures: it perpetually holds a range of maturities, so its price floats with rates forever. Neither is riskier in aggregate — the fund is just a ladder that automatically rolls — but a ladder can make an interest-rate loss disappear from your experience if you never need to sell early, while a fund makes every rate move visible in the balance.

Where funds win

• Zero maintenance: no reinvesting rungs, no picking CUSIPs, no auction calendars. Automatic and permanent.
• Instant diversification beyond Treasuries if you want it (corporate, mortgage, international) in one ticker.
• Any dollar amount, any time — no lumpy $1,000 increments or thin secondary-market pricing on small lots.
• Automatic dividend reinvestment keeps every coupon compounding without you lifting a finger.
• Simple in retirement accounts, where funds' tax indifference and your desire for simplicity align.

Where ladders win

• Dated liabilities: tuition, a house, a bridge to Social Security. Maturity dates matched to spending dates eliminate rate risk.
• Psychology: retirees sleep better knowing next year's spending arrives at face value regardless of headlines.
• Cost: Treasuries bought at auction through a major broker cost $0/year. Even a cheap fund charges a few basis points forever.
• Control of state taxes: Treasury interest is state-tax-free either way, but funds mixing in other bonds dilute that benefit.
• No forced selling: fund shareholders collectively selling in a panic can realize losses; your ladder ignores other people's behavior.

The honest complication: reinvestment and yield

Ladder fans sometimes claim ladders 'avoid losses funds suffer.' Not quite — if rates rise, your ladder's existing rungs are worth less too; you just don't look. Meanwhile the fund reinvests at higher yields exactly like your maturing rungs do. Over long horizons with reinvestment, a ladder and a fund of the same duration deliver very similar returns. The genuine differences are cash-flow certainty, costs, and behavior — not a secret free lunch.

The bottom line

For money with a date on it, a Treasury ladder is the precision tool: known dollars on known days, zero fund fees, zero rate anxiety. For general portfolio ballast with no specific spending date, a cheap Treasury or total bond fund does the same job with none of the homework. Many retirees sensibly run both — a ladder covering the next 5 years of spending, funds behind it. Choose by whether your money has an appointment.

Building a real ladder: mechanics and costs

Suppose you want $100,000 available across the next five years. At any major brokerage you buy five Treasury positions of $20,000 each, maturing in roughly one, two, three, four, and five years — either at auction (free at Fidelity, Schwab, and Vanguard) or in the secondary market, where spreads on Treasuries are tiny. In late 2025 that ladder yields roughly 4% blended. Each year a rung matures at exactly face value; you spend it if the money is needed or buy a new five-year rung if not, and the ladder rolls on indefinitely. Total cost: essentially zero — no expense ratio, no advisor. The trade-offs are practical rather than financial: five positions to track instead of one fund, interest that arrives semiannually rather than as a tidy monthly distribution, and state-tax-exempt but federally taxable interest to report. TreasuryDirect works too, though most investors find a brokerage more convenient for record-keeping and eventual sales.

1. 1
   Define the need

   List the specific years you need specific dollars — tuition 2027-2030, or living expenses for the first five years of retirement. Ladders shine when the liability schedule is concrete.

2. 2
   Buy one rung per year of need

   Purchase Treasuries maturing just before each payment date, at auction or on the secondary market. Round lots of $1,000 face value; no fund minimums.

3. 3
   Hold to maturity, ignore prices

   Statement values will wiggle with rates, but each rung pays face value on schedule regardless. This is the ladder's psychological superpower.

4. 4
   Roll or spend at each maturity

   If the cash is needed, it arrives on time by construction. If not, reinvest into a new long rung and the ladder becomes a perpetual income machine.
