Bond mutual funds (sometimes known simply as bond funds) and bond ETFs (or exchange-traded funds) both feature a basket of bonds or other debt instruments – but there are some key differences that investors should be aware of.
Bond funds are mutual funds that pool capital from investors, from which a fund manager allocates that capital to various fixed-income securities. A bond ETF instead tracks an index of bonds with the goal of matching the returns from the underlying index.
Key Takeaways
- Bond funds and bond ETFs or exchange-traded funds both invest in a basket of bonds or debt instruments.
- Bond funds or mutual funds contain a pool of capital from investors through which the fund is actively managed and whereby capital is allocated to various securities.
- Bond ETFs track an index of bonds designed to match the returns from the underlying index and typically have lower fees than mutual funds.
Understanding Bond Funds and Bond ETFs
Bond funds and bond ETFs share several characteristics, including diversification via portfolios that hold numerous bonds. Both funds and ETFs have smaller minimum required investments that would be necessary to achieve the same level of diversification by purchasing individual bonds in constructing a portfolio.
Before comparing bond funds and bond ETFs, it is worth taking a few moments to review the reasons why investors buy bonds. Most investors put bonds in a portfolio to generate income. A bond is a debt instrument that typically pays an interest rate, called a coupon rate each year to the bondholder. Although buying and selling bonds to generate a profit from fluctuations in their prices is a viable strategy, most investors invest in them for their interest payments.
Investors also buy bonds for risk-related reasons, as they seek to store their money in an investment that is less volatile than stocks. Volatility is the extent to which a security’s price fluctuates over time.
Both bond funds and bond ETFs can pay dividends, which are cash payments from companies for investing in their securities. Both types of funds offer a wide variety of investment choices ranging from high-quality government bonds to low-quality corporate bonds and everything in between.
Both funds and ETFs can also be purchased and sold through a brokerage account in exchange for a small per-trade fee. Despite these similarities, bond funds and bond ETFs have unique, unshared characteristics.
Note
All else being equal, ETFs are usually more flexible. However, this flexibility may not be the best case in all situations. For example, retirement funds want stability, so intraday trading flexibility is actually not entirely ideal.

Bond Funds
Mutual funds have been investing in bonds for many years. Some of the oldest balanced funds, which include allocations to both stock and bonds, date back to the late 1920s.
Accordingly, a large number of bond funds in existence offer a significant variety of investment options. These include both index funds, which seek to replicate various benchmarks and make no effort to outperform those benchmarks, and actively managed funds, which seek to beat their benchmarks.
Actively managed funds also employ credit analysts to conduct research into the credit quality of the bonds the fund purchases to minimize the risk of purchasing bonds that are likely to default. Default occurs when the issuer of the bond is unable to make interest payments or pay back the original amount invested due to financial difficulty. Each bond is assigned a credit quality grade by credit rating agencies that assess the financial viability of the issuer and the likelihood of default.
Bond funds are available in two different structures: open-ended funds and closed-end funds. Open-ended funds can be bought directly from fund providers, which means they do not need to be purchased through a brokerage account. If purchased directly, the brokerage commission fee can be avoided. Similarly, bond funds can be sold back to the fund company that issued the shares, making them highly liquid or easily bought and sold.
In addition, open-ended funds are priced and traded once a day, after the market closes and each fund’s net asset value (NAV) is determined. The trading price is a direct reflection of the NAV, which is based on the value of the bonds in the portfolio.
Open-ended funds do not trade at a premium or a discount, making it easy and predictable to determine precisely how much a fund’s shares will generate if sold. A bond sold at a premium has a higher market price than its original face value amount while a discount is when a bond is trading at a lower price than its face value.
Notably, some bond funds charge an extra fee if they are sold prior to a certain minimum required holding period (often 90 days), as the fund company wishes to minimize the expenses associated with frequent trading.
Bond funds do not reveal their underlying holdings on a daily basis. They generally release holdings on a semi-annual basis, with some funds reporting monthly. The lack of transparency makes it difficult for investors to determine the precise composition of their portfolios at any given time.
Bond ETFs
Bond ETFs are a far newer entrant to the market when compared to mutual funds, with iShares launching the first bond ETF in 2002. Most of these offerings seek to replicate various bond indices, although a growing number of actively managed products are also available. Because of their passive approach, ETFs often have lower fees than their mutual fund counterparts, potentially making them the more attractive choice to some investors all else being equal.
Bond ETFs operate much like closed-end funds, in that they are purchased through a brokerage account rather than directly from a fund company. Likewise, when an investor wishes to sell, ETFs must be traded on the open market, meaning that a buyer must be found because the fund company will not purchase the shares as they would for open-ended mutual funds.
Like stocks, ETFs trade throughout the day. The prices for shares can fluctuate moment by moment and may vary quite a bit over the course of trading. Extremes in price fluctuation have been seen during market anomalies, such as the so-called Flash Crash of 2010. Shares can also trade at a premium or a discount to the underlying net asset value of the holdings.
While significant deviations in value are relatively infrequent, they are not impossible. Deviations may be of particular concern during crisis periods, for example, if a large number of investors are seeking to sell bonds. In such events, an ETF’s price may reflect a discount to NAV because the ETF provider is not certain that existing holdings could be sold at their current stated net asset value.
Bond ETFs usually do not have a minimum required holding period, meaning that there is usually no penalty imposed for selling rapidly after making a purchase. Keep in mind there may be restrictions on then withdrawing the proceeds based on how that bond ETF is being held. For example, holding a bond ETF within a retirement vehicle may limit when those funds can be accessed without penalty fees or taxes (even though you can still sell).
They can also be bought on margin and sold short, offering significantly greater flexibility in terms of trading than open-ended mutual funds. Margin involves borrowing money or securities from a broker to invest. Also, unlike mutual funds, bond ETFs reveal their underlying holdings on a daily basis, giving investors complete transparency.
Important
Both bond funds and bond ETFs have similarities, though the holdings within the funds and their fees charged to investors can vary.
The decision over whether to purchase a bond fund or a bond ETF usually depends on the investment objective of the investor. If you want active management, bond mutual funds offer more choices. If you plan to buy and sell frequently, bond ETFs are a good choice. For long-term, buy-and-hold investors, bond mutual funds, and bond ETFs can meet your needs, but it’s best to do your research as to the holdings in each fund.
If transparency is important, bond ETFs allow you to see the holdings within the fund at any given moment. However, if you’re concerned about not being able to sell your ETF investment due to the lack of buyers in the market, a bond fund might be a better choice since you’ll be able to sell your holdings back to the fund issuer.
As with most investment decisions, it’s important to do your research and speak with your broker or financial advisor.
Bond ETFs often have lower expense ratios than bond funds. This is because ETFs have passive management. Bond funds may have higher expenses because of the active management and the costs associated with mutual fund operations.
Bonds or Bond ETFs: Which is the Better Investment?
Both bond funds and bond ETFs can offer suitable investment opportunities, but their appeal will depend on your personal investment goals, risk tolerance, and the specifics of your financial strategy.
Bond funds stand out for those seeking diversified exposure across various types of bonds, such as government, municipal, and corporate bonds, within a single investment. They’re particularly attractive for investors aiming for regular income and lower volatility compared to stocks. The professional management of these funds can also be a plus for investors who prefer to delegate investment decisions. However, it’s important to be mindful of the potential for higher fees, especially with actively managed funds, and the impact of interest rate changes on fund values.
Bond ETFs, on the other hand, combine the diversified exposure of bond funds with the flexibility and liquidity of stocks. They are traded on exchanges throughout the trading day, offering real-time pricing and the ability to respond swiftly to market changes. With generally lower expense ratios than mutual funds, bond ETFs are a cost-effective way to access the bond market. Their daily transparency and the ease of tracking an index can be particularly appealing for those who value cost efficiency and operational simplicity. However, like bond funds, bond ETFs are also subject to market risk, including changes in interest rates and credit risk.
What Is the Typical Minimum Investment for Bond Funds and Bond ETFs?
Bond funds may have minimum investment requirements, which can vary widely from fund to fund. Some may have minimum investments of a few thousand dollars. Bond ETFs, on the other hand, usually do not have minimum investment requirements.
Can I Use Bond Funds or Bond ETFs to Generate Income?
Yes, both bond funds and bond ETFs can be used to generate income. They both invest in bonds which typically pay periodic interest or coupon payments.
Do Bond Funds or Bond ETFs Offer Better Transparency to Investors?
Bond ETFs often provide better transparency because they have to disclose their holdings on a daily basis. Investors can see exactly what bonds are held within the ETF. Meanwhile, bond funds often disclose their holdings less frequently, perhaps only disclosing information on a quarterly basis to meet external reporting requirements.
Why Do Bond ETFs Lose Value?
Bond ETFs can lose value due to several factors, including changes in interest rates, credit risk, and market sentiment. When interest rates rise, the prices of existing bonds, which have lower interest rates compared to new bonds, tend to fall. Since a bond ETF holds many such bonds, its value can decrease as well. The duration of the ETF’s portfolio will tell you how sensitive it is to interest rate changes. Additionally, if the creditworthiness of the bonds within the ETF deteriorates, this can also lead to a decrease in the ETF’s value. It’s important to remember that while bond ETFs offer liquidity and the flexibility of trading like stocks, they are not immune to the risks inherent in the bond market.
Are Bond Funds Riskier than Bonds?
Investing in a bond fund is not necessarily riskier than investing in a bond. If you decide to invest in a bond fund, it is important that you understand what the fund is invested in. Read the fund’s stated objectives to ensure that they are in line with your risk profile.
The Bottom Line
Bond funds and bond ETFs are two investment options that pool funds into a diversified, fixed-income portfolio. However, there are substantial differences in how each operates, including whether or not each option can trade intraday and whether or not each option is tax-efficient.
