Bonds are not sexy. Instead of owning a slice of a company as you do with stocks with bonds, you loan money to a company—or the government—so they can do what they do.

But why would an individual investor want to loan money? Do I really need bonds in my portfolio?


Do I Need Bonds in my Portfolio?

So, do I need bonds in my portfolio?

What a great question to ask! The Financial Independence Retire Early crowd says “VTSAX and forget it,” but is that right for everyone?

Probably not. Everyone needs bonds, at least initially. Let me tell you why.

Recency Bias

Have you ever lost 40% of your portfolio’s value? The market has been on a 12-year run, and many have not experienced the gut-wrenching feeling of losing (at least on paper) a good chunk of your hard-earned money. This is recency bias, where the status quo will continue indefinitely.

Remember, the market ALWAYS goes down. This is a feature, not a bug of the market. So until you know how you will react to that fact, think about bonds. Bonds protect you from gut-wrenching declines.

The essential part of investing (aside from just doing it) is not to sell low. When the market tanks and you panic, you lose the game of investing.

The Game of Investing

Who me? I won’t panic.

Remember, investing is a game of one. It is you against you. But, if history is a guide, you win if you don’t sell out at the worst time.

Investing is not a zero-sum game; everyone can win if you play by the rules. When investing, you participate in the growth of the economy in general. More people, more products, more consumption, and that growth is why stocks go up over time.

Paper losses aren’t real; panic selling, however, locks in the loss.

Don’t Sell Low

So, how can you not sell low?

One way: lose the password to your investment account. Seriously. If you have a 401k, set it up how you want it.  Then lose your password. Don’t check it for another 1-2 years. There is nothing you want to do in there anyway.

Or cancel cable. Remember, TV’s job is to sell eyeballs advertising, and literally, there is nothing meaningful you might learn about investing or the stock market on TV.

Or stop talking to other people about hot stock tips. For example, change the subject if a friend mentions bitcoin or blockchain (or Blockbuster). Your friend is going to lose money.

You are going to lose your password.

Why Invest in Bonds?

Bonds are volatility dampeners. That’s it; that’s the secret. They reduce the downside of investing. They are not for providing income. Later in de-accumulation, they can provide cash when the market is down, but for accumulation, you have bonds because they dampen volatility.

Figure 1 (Asset Allocation and Maximal Loss)

In figure 1 above, we see what effect asset allocation (bond percentage) has on maximum loss. If you are in 100% stocks, you can lose 50%. If you are in a 60/40 portfolio, you lose much less at 25%.

Next, let’s talk about which bonds you should have in your portfolio.

Which Bonds Should I have in My Portfolio?

Total bond indexes are often suggested as a part of the three-fund portfolio. Use a total bond index if you want some increased return during the good years, but if you’re going to have proper downside protection, US treasuries are the way to go.

There is a flight to safety (for the most part) when the stock market tanks, so US treasuries are the place to be if you genuinely want to dampen volatility. In addition, you can use long-duration bonds for the most (theoretically) negative correlation.

But the main competitor with a total bond index in an intermediate duration treasury ETF. So let’s look closely now at the best two kinds of bonds.

Basics of Bond Funds

Individual Bonds vs. Bond Funds

Most folks don’t want to bother with individual bonds. Sure, you can go to treasury direct or even buy individual bonds on many custodians. But honestly, why bother. Instead, you should use bond ETFs or bond mutual funds.

Bond ETFs vs. Bond Mutual Funds

Honestly, it doesn’t matter if you use Bond ETFs or Bond Mutual funds. Before 2020, there was a concern that Bond ETFs might have problems if there was a large amount of selling pressure, but they came through relatively well. So you can use either bond ETFs or Mutual Funds, depending on cost.

Bonds: Active vs. Passive

There may be a role for active management in bonds. Pay attention to costs, however! Since returns are muted with all bonds, costs are even a more significant consideration than usual. Also, active management may lead to more tax consideration, making ETFs and tax-deferred accounts a consideration if you want active funds.

What is the Best Kind of Bond to Own: Easy Version


Let’s start with the easy version. What is the best kind of bond to own if you need bonds in your portfolio:

best bond fund if I need bonds

Above, you can compare the two primary considerations for the kind of bonds to own and what makes them better than the other.

First off, we have intermediate treasuries (which can be an ETF or mutual fund). Next, you have total bond funds (ETFs or mutual funds).

You expect slightly higher returns during the “good” times between market crashes with the total bond fund. In addition to about 30% intermediate treasuries, this is because they have corporate bonds and some other kinds of governmental bonds. You, of course, need to do a deep dive on the total bond fund you are exploring, but the whole point is to own a more representative sample of total US bonds with the total bond fund.

On the other hand, Intermediate treasuries are US treasuries with a duration of around 6-7 years. These are considered as high quality as bonds get. Even though they may not pay as much during the good years because of “flight to safety,” they retain their value well during a market crash.

The two best bond funds are intermediate treasuries and total bond funds.

What is the Best Kind of Bonds to Buy: Complete Version

Next, let’s get complicated.

As I mentioned, there are a lot of different kinds of bonds.

best kind of bond funds


Above, you can see the different kinds of bonds on the left, and some of them even have duration. See my blog for a discussion on TIPS (especially TIPS Duration).

Let’s look at returns first. Above, under Return, you can see Junk Bonds have the highest yield of the bonds listed. Cash has the lowest yield. In general, the shorter the duration, the less the return. Corporates bonds pay better than treasuries primarily due to credit risk.

But say you are interested in a negative correlation with the stock market. What will keep its price the best (or even increase) when the stock market crashes? Under “Neg Corr” above, you can see the most negatively correlated with stock market crashes. Again, long-term treasuries are the best here, and Junk Bonds are highly positively correlated with stock crashes. Most of the other bonds, as you can see, don’t have as consistent correlations, but you can see trends reflected above.

Next, we can see what might be expected to do well with increasing inflation. I-Bonds are sexy lately.

The final category is credit risk. Products from the US government are considered to have no credit risk as they are backed by the full faith of the US government.

So, how do intermediate treasuries and total bond funds do in the above comparison? First, you can see that total bond funds aren’t too great (or too bad!) in any above categories. The idea is that they are pretty good for most. On the other hand, Intermediate treasuries might return a little less but might keep their value a bit better during a correction.

What is the best bond fund if I decide I need bonds?

So, in summary, for most, a total bond fund or an intermediate treasury fund is all you need. Of course, there are many other bonds (or, more accurately, fixed income products) for you to choose from, but start simple!

Next, consider your asset allocation and decide on asset location. For the most part, bonds go into your tax-deferred account. It is ok to use a target-date fund, but remember, target-date funds are not good in retirement!

Many should consider bond alternatives given the low-interest-rate environment we are in. But, again, the idea is not to replace all your bonds, but once you understand why you have bonds, you might be able to (at least in some circumstances) do better with other options.

Finally, if you want to be an excellent DIY investor, understand that you must invest consistently in a reasonable way. Still, there is a pre-retirement glidepath to de-risk your investment.


Bonds in Target Date Funds

Finally, let’s look at bonds in target-date funds. “do I need bonds” is usually answered by the bonds in your target-date fund.

Target Date funds have stocks and bonds in a pre-set ratio depending on your age.

Do I need bonds in my portfolio?

From Vanguard

Above, you can see how target-date funds go from a 3-fund portfolio and increase bonds as you get closer to retirement. Note when “young” a 10% bond allocation. Again, this is downside protection.

Remember, target-date funds may be acceptable for accumulation, but you should not use target-date funds when you are retired!

Summary: Do I really need Bonds in my Portfolio?

Bonds are not sexy, but there is something to be said about the stabilizing effect on your portfolio.

When the market is falling apart—If they stop you from selling low—they are worth their weight in gold.

Bonds hedge against making panic decisions.

If you are new to investing and have never been through a significant drop in the market, have bonds in your portfolio. During the peak of despair, you may not need bonds if you can ignore the panic on TV and among your friends.

If your response to a market crash instead is to buy stocks when they are on sale, maybe that is the time to sell your bonds and go all-in on stocks. You will be buying low!

Remember, in the beginning, savings rate is all that matters. Returns on your investment don’t matter until later. So to learn how to use bonds when you are young, you will need to use them later! And, of course, why take downside risk until you are sure you can tolerate it?

Good asset location dictates that you should have most of your bonds in your pre-tax retirement accounts. However, if you need to have bonds in your brokerage account, consider Municipal bonds if you are in a high tax bracket.

Stay away from “high-yield” bonds, AKA Junk Bonds. Remember, the point of bonds is a dampener of volatility, so don’t go reaching for yield in your bonds (that’s what stocks are for).

Bonds are complicated. There is duration and convexity, default and interest rate risk, coupon, etc. Do I really need bonds in my portfolio? Yes.

  1. I was always virtually 100% stocks in my investments until a couple of years before retirement. And I’m glad, I’d have much less now had I gone with a balanced approach. I don’t see a reason to have bonds until retirement is drawing near. I saw my portfolio crash more than once. Big deal, I wasn’t going to need that money anytime soon so why would that bother me? Why would it bother any rational person who has even a little familiarity with the stock market’s historical performance? I understand that there are some people who panic and do stupid things. But there are a lot of us that stick with our long term plan no matter what. In retirement I do have a balanced portfolio because I’ve won the game and all I have to do now is not be a big loser. Bonds insure I’ll be a loser but only a small one and that’s fine with me.

  2. Great post! So if I want bonds for ballast in my portfolio, an intermediate treasury fund is the way to go? Do the risk parity folks have it wrong when they cite long term treasuries as the best ballast to equities given lowest correlation to equities? Are they forgetting that correlations change in different market environments? I can see something like the 1974 bear market, where inflation and interest rates were super high, would bring long term treasuries and stocks closer to 1, right?

    • Some say short only bonds, some say intermediate, or total bonds. Some say long only. And many now say cash instead of bonds. Some even say TIPs or now I-Bonds are sexy. Who is right? It depends on what you want your bonds to do for you. The right answer… I’ll tell you in 10 years.
