Bond ETFs vs individual bonds: maturity, risk and cost compared

There are two ways to own bonds. You can buy an individual bond: one loan to one borrower, with a fixed coupon and a date when your principal comes back. Or you can buy a bond fund, usually today an exchange-traded fund (ETF), that owns hundreds or thousands of bonds and keeps replacing them as they age. Both pay interest and both lose value when rates rise, but they behave differently over time.

The argument usually starts with one line: "If I hold the bond to maturity, I can't lose money." That is true of the dollars you get back and misleading about what you earn. This guide works through what really differs between the two: maturity, interest-rate risk, diversification, costs and income. It includes a worked example showing why a fund and a bond can end up in exactly the same place after a rate rise.

The core difference: a fixed date versus a rolling portfolio

A bond's life has a shape. Its duration, the measure of how much its price moves when yields change, shrinks every year as maturity approaches. On the last day it is worth exactly its face value, whatever interest rates are.

A fund has no shape. An index fund that tracks, say, Treasuries maturing in 7 to 10 years sells a bond once it has less than 7 years left and buys a new 10-year bond. Its duration, its yield and its interest-rate risk stay roughly where its rules put them, indefinitely. You choose when your exposure ends by selling, not by waiting.

That leads to the main practical differences:

Does holding to maturity avoid the loss?

It avoids a realized loss in dollars, but not the economic cost of a rate rise. Here is the arithmetic.

The example is simplified: it assumes yields stay at 5%, the fund's duration holds steady, and no fees or taxes. But the lesson holds generally. Rising rates cost every bondholder something; the only choice is whether it shows up as a lower price today or as lower income than the market offers later. The Bonds and fixed income: how bonds work, pay and lose value guide covers the price-yield relationship behind the example.

Real data: when a fund's bonds never come due

From July 2020 to October 29, 2026, TLT, an ETF of Treasuries with more than 20 years to maturity, fell from $171.00 to $81.49 on monthly closes, price only: it lost more than half its price. IEF, which holds 7-to-10-year Treasuries, fell 27.0% from its July 2020 peak to its October 2023 low. SHY, holding 1-to-3-year Treasuries, fell only 6.7% at worst (April 2020 to September 2023), because its short bonds are replaced quickly with higher-yielding ones.

Compare an individual bond. In July 2020 the 10-year Treasury yield averaged 0.62% for the month, its lowest monthly average since the series began in 1953. A 10-year note bought then would also have shown a large loss in market value by 2023, but it is still scheduled to pay its full face value in 2030. A holder who never needs to sell it will get exactly the cash flows they signed up for: 0.62% a year, well below the 5%-plus that later Treasuries paid. Both kinds of owner felt the rate shock; they felt it in different places.

These are price-only numbers. Bond funds pay out their interest as distributions, which price charts leave out, so total returns were better than the price lines show.

When each one fits

Individual bonds suit known future bills. If you owe a known amount on a known date, such as tuition in 2029, a bond maturing just before that date matches the need exactly. Several bonds with staggered maturities form a bond ladder: each year one matures, and the money is spent or reinvested at the longest rung.

Funds suit everything else. For corporate, high-yield and municipal bonds, single bonds carry real default risk, and spreading money across hundreds of issuers protects against any one of them failing. ETFs also trade like stocks, with a quoted price all day, and their monthly distributions can be reinvested through a broker's dividend reinvestment option.

Between the two sit target-maturity or defined-maturity ETFs, which hold bonds that all mature in one year and then liquidate, combining a fund's diversification with an end date.

Pitfalls and limitations

• Markups on individual bonds. Corporate and muni bonds trade through dealers, and the price you pay can include a markup that is hard to see. Check recent trade prices on FINRA's TRACE for corporates or the MSRB's EMMA for munis before buying.
• Single-issuer risk. One default in a small portfolio of corporate bonds can wipe out years of extra yield.
• Calls. A callable bond may be repaid early, ending your "hold to maturity" plan when rates have fallen and reinvesting is least attractive.
• Fund price gaps. A bond ETF can trade above or below the value of its bonds, especially in stressed markets when the underlying bonds trade rarely; see What is an ETF? How exchange-traded funds work.
• Fees compound. A fund's expense ratio is charged every year; compare it with the one-time cost of buying a bond. See Expense ratios and fund costs: what you pay and how it compounds.
• Distributions vary. Fund income changes as bonds roll over, so it is less predictable than a single bond's coupons, in both directions.

How Finabase does it

Finabase does not list individual bonds or their prices, and it has no bond-fund screener. For individual Treasuries, the Treasury yields table shows what notes and bonds yield at each maturity from 1 month to 30 years. Bond ETFs have full symbol pages: TLT, SHY and AGG chart the fund's price, and the Dividends & splits tab lists its monthly distributions. The fund's Holders tab can show its composition (issuer, expense ratio, holdings count) when that data is available for the fund. The worked numbers on this page are our calculations.

Frequently asked questions

Do bond ETFs ever mature?

Most don't. A typical bond ETF keeps a target maturity range by selling bonds as they age and buying new ones, so it has no end date. Target-maturity ETFs are the exception: they hold bonds maturing in one year and close when those bonds mature.

Is it safer to hold individual bonds to maturity?

You get the promised face value back if the issuer doesn't default, which a fund can't promise. But you still bear the cost of a rate rise, as income below what new bonds pay, and with one issuer you carry more default risk than a diversified fund.

Why did my bond fund lose money when rates went up?

Because the bonds it owns pay less than newly issued bonds, so their market prices fell. The fund then reinvests maturing bonds and new cash at the higher yields, which gradually makes up the loss over a period roughly equal to its duration.

Are bond ETFs or individual bonds cheaper?

It depends on the bond. Treasuries can be bought at auction through TreasuryDirect in $100 increments, with no ongoing cost after purchase. For corporate and municipal bonds, small trades go through dealers whose markups can be significant and hard to see, so compare recent trade prices on TRACE or EMMA with the fund's yearly expense ratio before deciding.

Summary

An individual bond ends on a date and repays its face value; a bond fund rolls its bonds forever and keeps its interest-rate risk roughly constant. Rising rates cost both: the bond as income below new market yields, the fund as a price drop it earns back through higher reinvestment yields, and in the worked example both end at $12,241 per $10,000. TLT's price fell by more than half from 2020 to 2026 because its long bonds never come due, while SHY's short bonds kept its worst decline to 6.7%. Individual bonds and ladders fit known future spending, especially with Treasuries; funds fit investors who want diversified corporate or muni exposure in small amounts.
