How a Bond Ladder Spreads Out Interest-Rate Risk

A bond ladder splits money across bonds that mature at regular, staggered dates, so only a slice of the portfolio has to be reinvested at whatever rates prevail on any given date. That spreads two risks: the income risk of reinvesting everything at once at a lower rate, and the price risk of being forced to sell a long bond after rates have risen. It does not remove either risk, and the worked example below shows where it helps and where it does not.

Key takeaways

On Treasury yields from October 21, 2026, a $50,000 ladder with $10,000 in each of five rungs (1 to 5 years) earns about $2,409 a year, a weighted average yield of 4.82%, against $2,260 for $50,000 in a 1-year bill.
If rates shift by one point after the first rung matures, the ladder's annual income moves by $100 in year 2, while a rolled 1-year bill moves by $500. Over five years, the ladder's total interest differs by $1,000 either way, against $2,000 for the roller.
The ladder's income edge is not free: with no rate change, all of its $974 five-year lead comes from the upward-sloping curve, because its longer rungs pay more than a 1-year bill, and if rates rise one point the roller finishes $26 ahead.
A one-point jump in yields would cut the market value of this ladder by about 2.7% (roughly $1,332), compared with about 4.3% ($2,135) for one 5-year note. For a bond held to maturity, that price change does not reduce the face value repaid.
Selling a rung early, CD early-redemption fees, callable bonds and CDs, dealer markups and the 45-day TreasuryDirect hold can all disrupt the schedule.

What a bond ladder is

A ladder is a portfolio of bonds with maturity dates spaced at regular intervals, with each "rung" holding bonds that mature at about the same time. A guide from a fund provider that also sells ladder ETFs, State Street Global Advisors' explainer on building a bond ladder, describes the standard routine: when the nearest rung matures, the proceeds can be reinvested at the far end of the ladder, where longer-term bonds typically pay higher rates, or spent.

The mechanism rests on the inverse link between rates and prices. The SEC's investor bulletin on interest rate risk states that higher market rates mean lower fixed-rate bond prices, and lower rates mean higher prices. The FINRA explainer on rates and duration adds that longer maturities tend to raise a bond's duration, a measure of how much its price moves: a duration of 10 implies roughly a 10% price move for each one-percentage-point change in rates, in the opposite direction.

A ladder uses that fact in two ways. Short rungs have low duration, so they barely move in price. And because a rung matures every year, a fixed slice of the money (20% in a five-rung ladder) is repriced to current rates each time, rather than all of it at once.

A $50,000 ladder on Oct. 21 yields

The following is an illustrative example, not a recommendation. It uses market yields on Treasury securities at constant maturity from the Federal Reserve's H.15 release, as republished by FRED for the series DGS5 (and its 1-, 2-, 3- and 10-year siblings), for October 21, 2026, the latest observation when this was written. The H.15 release has no 4-year constant maturity (it goes from 3 to 5 years), so the 4-year figure, 4.92%, is interpolated as the midpoint of the 3- and 5-year yields rather than an observed rate.

Rung	Amount	Yield used	Annual income
1 year	$10,000	4.52%	$452
2 years	$10,000	4.81%	$481
3 years	$10,000	4.89%	$489
4 years	$10,000	4.92% (midpoint)	$492
5 years	$10,000	4.95%	$495
Ladder	$50,000	4.82% weighted	$2,409
All in a 1-year bill	$50,000	4.52%	$2,260

weighted average yield = (sum of amount x yield) / total amount
= (10,000 x 4.52% + 10,000 x 4.81% + 10,000 x 4.89% + 10,000 x 4.92% + 10,000 x 4.95%) / 50,000
= $2,409 / $50,000 = 4.818%

The ladder earns $149 more a year than the 1-year bill, only because the yield curve is upward sloping on that date: the 5-year yield (4.95%) was higher than the 1-year yield (4.52%), and the 10-year was 5.13%. That is a snapshot, not a forecast, and it can reverse. The example ignores taxes, fees and the compounding of interest, and treats each yield as the rung's fixed annual rate.

What a one-point move does

Assume that right after the 1-year rung matures, yields across the curve move up or down by one percentage point and stay there. The matured $10,000 is reinvested at the 5-year yield plus or minus one point. The roller, with all $50,000 in a 1-year bill, must reinvest everything at the 1-year yield plus or minus one point.

Rates move	Ladder income, year 2	Ladder weighted yield, year 2	Roller income, year 2
1 point lower	$2,352	4.70%	$1,760
No change	$2,452	4.90%	$2,260
1 point higher	$2,552	5.10%	$2,760

The ladder reprices only the matured rung: $10,000 earning $395, $495 or $595 instead of the $452 it earned before. The roller's whole $50,000 changes by $500 in either direction. Each later year, one more rung reprices. In year 5, four of the five rungs carry the new rate, so income is $400 above or below the no-change figure; the last original rung matures at the end of year 5, after which the whole ladder sits at the new level.

Rates move	Ladder, year 5 income	Ladder, 5-year total	Roller, annual income, years 2-5	Roller, 5-year total
1 point lower	$2,075	$11,274	$1,760	$9,300
No change	$2,475	$12,274	$2,260	$11,300
1 point higher	$2,875	$13,274	$2,760	$13,300

Two readings follow from the numbers. First, the ladder's five-year interest swings by $1,000 either side of its unchanged total ($12,274), while the roller's swings by $2,000 either side of $11,300. Second, the comparison is not like-for-like: the ladder reinvests at the 5-year yield and the roller at the 1-year yield. So the ladder's $974 lead with no rate change ($12,274 against $11,300) comes entirely from the curve's slope. When rates fall one point, the lead grows to $1,974: $974 from the slope and $1,000 from the ladder keeping its older, higher rates for longer. When rates rise one point, that same $1,000 lag works against the ladder and outweighs the slope, so the roller ends $26 ahead ($13,300 against $13,274). Spreading risk is not the same as winning, and the extra income from longer rungs comes with more price risk, shown in the next section. All five-year totals are simple sums of annual interest, before tax.

Price risk and the fund comparison

Income risk is only half of the picture. If you sell before maturity, the SEC's investor page on bonds says the bond may be worth more or less than face value, while held to maturity the investor receives face value plus interest. The same FINRA duration page notes that for a buy-and-hold investor, the market price "doesn't matter much" unless a sale is planned.

To size the exposure, the example prices each rung as a semiannual-pay bond issued at par at the yield in the table above, then raises every yield by one point at once (a simplified calculation, not a quote).

Holding	Value change if yields rise 1 point	Value change if yields fall 1 point
$50,000 in a 1-year bond	-0.96% (about -$480)	+0.97% (about +$487)
$50,000 ladder, 1 to 5 years	-2.66% (about -$1,332)	+2.77% (about +$1,385)
$50,000 in one 5-year note	-4.27% (about -$2,135)	+4.50% (about +$2,249)

The ladder sits between the two single maturities, at roughly the price sensitivity of its 3-year rung. If a bond fund is the alternative, FINRA's duration page says a fund's duration is listed on its fact sheet, while for an individual bond finding it "can be trickier". The FINRA bonds page adds that bond funds charge fees and expenses, and that rate changes have a greater impact on the share price of funds holding bonds with longer average lives. A ladder's rungs, by contrast, each have a set maturity date at which face value is repaid if the bond is held and the issuer pays.

Building blocks and their rules

Treasuries

TreasuryDirect lists bills with terms up to 52 weeks, notes issued at 2, 3, 5, 7 and 10 years, and TIPS issued at 5, 10 and 30 years. There is no 4-year note, so that rung would be a longer note bought with about four years remaining. TreasuryDirect's buying page shows two routes, TreasuryDirect itself or a bank, broker or dealer, with a $100 minimum and $100 increments at auction.

CDs

The FDIC covers time deposits such as CDs, up to $250,000 per depositor, per insured bank, for each ownership category, according to its deposit insurance overview. The same page lists Treasury securities and municipal securities as not covered by FDIC insurance.

Municipal bonds

Interest on municipal bonds generally is exempt from federal income tax, and may also be exempt from state and local taxes for residents of the issuing state, the SEC's bond page says. "Generally" matters: IRS Publication 550 lists exceptions, and interest on a private activity bond that is not a qualified bond, for example, is taxable.

Taxes by rung

IRS Publication 550 says interest from Treasury bills, notes and bonds is subject to federal income tax but exempt from all state and local income taxes. Bills (4 to 52 weeks) are issued at a discount, and the gain is generally reported when the bill is paid at maturity; note interest is reported in the year paid. Tax-exempt municipal interest can still produce a reportable capital gain or loss if the bond is sold.

Costs, call risk and selling early

Buying through a dealer carries a price markup, and selling can carry a markdown, which the FINRA bonds page describes as the firm's compensation. FINRA says the price received on a sale depends on where the bond currently trades in the secondary market, and its bond liquidity page notes bonds can trade infrequently and that rising rates can make it harder to sell at a desirable price.

Call features are the other interruption. The SEC's bond page defines call risk as an issuer retiring a bond before maturity, something it might do if rates decline, and FINRA's callable bond page says an issuer may redeem early to refinance at a lower rate. A called rung returns money after rates have fallen, when reinvesting it pays less, which breaks the ladder's schedule.

The FDIC's guide, Shopping for a Certificate of Deposit?, applies the same logic to CDs: if rates fall, the bank may call a callable CD and return the money plus accrued interest. The same guide covers cashing a CD rung early: the terms of most fixed-rate CDs let the depositor pay a fee to redeem before maturity, while most market-linked CDs do not allow early redemption.

Frequently asked questions

Can a Treasury rung bought in TreasuryDirect be sold early?

Not inside TreasuryDirect. Its page on selling marketable securities says a sale has to go through a bank, broker or dealer, so the security must first be transferred out. It also has to be held in the TreasuryDirect account for 45 days before it can be sold or transferred, which means a 4-week bill held there cannot be sold before it matures.

How much money does a ladder need?

That depends on the bonds. Treasuries at auction start at $100, as noted above, but the State Street guide says individual bonds generally have a $1,000 par value and that buying in small quantities can mean higher trading costs, which can erode yield. A five-rung ladder means at least five separate purchases, so those costs repeat.

Are brokered CDs covered by FDIC insurance?

Coverage applies to CDs held at FDIC-insured banks, up to $250,000 per depositor, per bank, per ownership category. The FDIC warns that if you buy through a third-party broker and the broker fails to place your funds into a CD at an insured bank, the money is not insured. Verify the issuing bank and read the account documents.

Does a CD ladder create tax bills before the CDs mature?

It can. IRS Publication 550 says that for a CD with a maturity of more than one year, you include a part of the total interest in income each year under the original issue discount rules, even though the interest is paid at maturity. Treasury bills differ, since their discount is generally reported at maturity.

How can I tell whether a bond or CD in my ladder is callable?

For bonds, FINRA's callable bond page advises looking at a callable bond's yield-to-call, the return if it were redeemed at the earliest possible date, and notes that callable bonds sometimes pay a higher rate than similar noncallable bonds to compensate for call risk. For CDs, the FDIC says to read the deposit agreement closely.

A checklist before you build one

Decide the amount you will not need before each rung matures, since selling early can change the result.
Pick the maturities and write down each rung's yield and date, with the source and date of the yield.
Check each bond or CD for call features, and for CDs confirm the issuing bank and the broker's placement.
For corporate and agency bonds, check recent trading in FINRA's Fixed Income Data before buying, and look for any commission on the trade confirmation.
Decide in advance whether a maturing rung is reinvested at the long end or spent, and note which account holds each rung, since the tax treatment above differs by type.

The example above adds up interest without reinvesting it. To see what compounding adds, the investment growth calculator can run $50,000 at the ladder's 4.82% weighted yield over five years.
