Over the long term, why invest in bonds?
"If I don't need this money for decades, meaning I can ride out periodical market crashes, why would I invest in bonds instead of funds that track broad stock market indexes? You wouldn't.  But you can never be 100% sure that you really won't need the money for decades.  Also, even if you don't need it for decades, you can never be 100% certain that the market will not be way down at the time, decades in the future, when you do need the money.  The amount of your portfolio you allocate to bonds (relative to stocks) can be seen as a measure of your desire to guard against that uncertainty. I don't think it's accurate to say that ""the general consensus is that your portfolio should at least be 25% in bonds"".  For a young investor with high risk tolerance, many would recommend less than that.  For instance, this page from T. Rowe Price suggests no more than 10% bonds for those in their 20s or 30s. Basically you would put money into bonds rather than stocks to reduce the volatility of your portfolio.  If you care only about maximizing return and don't care about volatility, then you don't have to invest in bonds.  But you probably actually do care about volatility, even if you don't think you do.  You might not care enough to put 25% in bonds, but you might care enough to put 10% in bonds." Bonds provide protections against stock market crashes, diversity and returns as the other posters have said but the primary reason to invest in bonds is to receive relatively guaranteed income. By that I mean you receive regular payments as long as the debtor doesn't go bankrupt and stop paying. Even when this happens, bondholders are the first in line to get paid from the sale of the business's assets. This also makes them less risky. Stocks don't guarantee income and shareholders are last in line to get paid. When a stock goes to zero, you lose everything, where as a bondholder will get some face value redemption to the notes issue price and still keep all the previous income payments. In addition, you can use your bond income to buy more shares of stock and increase your gains there. "I can think of a few reasons for this. First, bonds are not as correlated with the stock market so having some in your portfolio will reduce volatility by a bit. This is nice because it makes you panic less about the value changes in your portfolio when the stock market is acting up, and I'm sure that fund managers would rather you make less money consistently then more money in a more volatile way.  Secondly, you never know when you might need that money, and since stock market crashes tend to be correlated with people losing their jobs, it would be really unfortunate to have to sell off stocks when they are under-priced due to market shenanigans. The bond portion of your portfolio would be more likely to be stable and easier to sell to help you get through a rough patch. I have some investment money I don't plan to touch for 20 years and I have the bond portion set to 5-10% since I might as well go for a ""high growth"" position, but if you're more conservative, and might make withdrawals, it's better to have more in bonds... I definitely will switch over more into bonds when I get ready to retire-- I'd rather have slow consistent payments for my retirement than lose a lot in an unexpected crash at a bad time!" Many folks use bonds to diversify their portfolio since bonds rise and fall in value at different times and for different reasons than stocks. Bonds pay interest on a regular basis (usually monthly or quarterly) and so some people invest in bonds in order to match the interest payments to some regular expense they might have. The interest payment does not change (fixed income).  For individual bonds, there is a maturity date at which you can expect to receive the face value of the bond (the issuer's creditworthiness is important here). You can make a little money on a bond by buying it when its value is lower than its face value and either selling later for a higher value, or waiting for it to mature.  Often the minimum investment for a single bond is high, so if you don't have a large enough amount, you can still get the performance of bonds through a bond fund. These do not mature, so you don't have a guarantee of a return of your investment. However, they have access to more bonds than retail investors, so the funds can keep your money more fully invested. If you don't need the income, you can reinvest the dividends and have a little extra capital growth this way.
You should definitely favor holding bonds in tax-advantaged accounts, because bonds are not tax-efficient. The reason is that more of their value comes in the form of regular, periodic distributions, rather than an increase in value as is the case with stocks or stock funds. With stocks, you can choose to realize all that appreciation when it is most advantageous for you from a tax perspective. Additionally, stock dividends often receive lower tax rates. For much more detail, see Tax-efficient fund placement. "The time value of money is very important in understanding this issue.  Money today is worth more than money next year, two years from now, etc. It's a well understood economics concept, and well worth reading about if you have some, well, time. Not only is money literally worth more now than later due to inflation, but there is the simple fact that, assuming you have money for the purpose of doing something, being able to do that thing today is better than doing that same thing tomorrow.  ""A bird in the hand is worth two in the bush"" gets to this rather directly; having it now is better than probably having it later.  Would you rather have a nice meal tonight, or eat beans and rice tonight and then have the same nice meal next year? That's why interest exists, in part: you're offered some money now, for more money later; or in the case of buying a bond, you're offered more money later for some money now.  The fact that people have different discount rates for money later is why the loan market can exist: people with more money than they can use now have a lower discount for future money than people who really need money right now (to buy a house, to pay their rent, whatever).   So when choosing to buy a bond, you look at the money you're going to get, both over the short term (the coupon rate) and the long term (the face value), and you consider whether $80 now is worth $100 in 20 years, plus $2 per year.  For some people it is - for some people it isn't, and that's why the price is as it is ($80).  Odds are if you have a few thousand USD, you're probably not going to be interested in this - or if you have a very long term outlook; there are better ways to make money over that long term.  But, if you're a bank needing a secure investment that won't lose value, or a trust that needs high stability, you might be willing to take that deal." A stock is an ownership interest in a company.  There can be multiple classes of shares, but to simplify, assuming only one class of shares, a company issues some number of shares, let's say 1,000,000 shares and you can buy shares of the company. If you own 1,000 shares in this example, you would own one one-thousandth of the company.  Public companies have their shares traded on the open market and the price varies as demand for the stock comes and goes relative to people willing to sell their shares. You typically buy stock in a company because you believe the company is going to prosper into the future and thus the value of its stock should rise in the open market. A bond is an indebted interest in a company.  A company issues bonds to borrow money at an interest rate specified in the bond issuance and makes periodic payments of principal and interest.  You buy bonds in a company to lend the company money at an interest rate specified in the bond because you believe the company will be able to repay the debt per the terms of the bond.  The value of a bond as traded on the open exchange varies as the prevailing interest rates vary.  If you buy a bond for $1,000 yielding 5% interest and interest rates go up to 10%, the value of your bond in the open market goes down so that the payment terms of 5% on $1,000 matches hypothetical terms of 10% on a lesser principal amount.  Whatever lesser principal amount at the new rate would lead to the same payment terms determines the new market value.   Alternatively, if interest rates go down, the current value of your bond increases on the open market to make it appear as if it is yielding a lower rate. Regardless of the market value, the company continues to pay interest on the original debt per its terms, so you can always hold onto a bond and get the original promised interest as long as the company does not go bankrupt. So in summary, bonds tend to be a safer investment that offers less potential return.  However, this is not always the case, since if interest rates skyrocket, your bond's value will plummet, although you could just hold onto them and get the low rate originally promised. "In the quoted passage, the bonds are ""risky"" because you CAN lose money. Money markets can be insured by the FDIC, and thus are without risk in many instances.  In general, there are a few categories of risks that affect bonds. These include: The most obvious general risk with long-term bonds versus short-term bonds today is that rates are historically low." When interest rates rise, the price of bonds fall because bonds have a fixed coupon rate, and since the interest rate has risen, the bond's rate is now lower than what you can get on the market, so it's price falls because it's now less valuable. Bonds diversify your portfolio as they are considered safer than stocks and less volatile. However, they also provide less potential for gains. Although diversification is a good idea, for the individual investor it is far too complicated and incurs too much transaction costs, not to mention that rebalancing would have to be done on a regular basis. In your case where you have mutual funds already, it is probably a good idea to keep investing in mutual funds with a theme which you understand the industry's role in the economy today rather than investing in some special bonds which you cannot relate to. The benefit of having a mutual fund is to have a professional manage your money, and that includes diversification as well so that you don't have to do that. This is a perfect example of why bonds are confusing at first glance.  Think about it this way...  You buy a 30-year Russian Bond at 4%.  An event happens that makes Russia risky to invest in.  You want to buy another bond but fuck 4%, you and the rest of the market want 6% to compensate you for the risk.  Now let's say you want to sell your 4% bond... Well you're going to have to drop the price of that bond in order for it to appeal to an investor that could go out and get a 6%. On a 30-year bond of that kind, you're looking at about 75% of what you bought it for.   So to wrap it up, high bond yields are great for buyers that don't already own them, but bad for sellers who want to get rid of their old ones. It is the opposite intuition as stocks and almost everything else. Bonds can increase in price, if the demand is high and offer solid yield if the demand is low.  For instance, Russian bond prices a year ago contracted big in price (ie: fell), but were paying 18% and made a solid buy.  Now that the demand has risen, the price is up with the yield for those early investors the same, though newer investors are receiving less yield (about 9ish percent) and paying higher prices.   I've rarely seen banks pay more variable interest than short term treasuries and the same holds true for long term CDs and long term treasuries.  This isn't to say it's impossible, just rare.  Also variable is different than a set term; if you buy a 10 year treasury at 18%, that means you get 18% for 10 years, even if interest rates fall four years later.   Think about the people buying 30 year US treasuries during 1980-1985.  Yowza. So if you have a very large amount of money you will store it in bonds as its much less likely that the US treasury will go bankrupt than your bank. Less likely?  I don't know about your bank, but my bank doesn't owe $19 trillion. I recall similar strategies when (in the US) interest rates were quite a bit higher than now. The investment company put 75% or so into into a 5 year guaranteed bond, the rest was placed in stock index options. In effect, one had a guaranteed return (less inflation, of course) of principal, and a chance for some market gains especially if it went a lot higher over the next 5 years.  The concept is sound if executed correctly. Short-term to intermediate-term corporate bond funds are available. The bond fund vehicle helps manage the credit risk, while the short terms help manage inflation and interest rate risk. Corporate bond funds will have fewer Treasuries bonds than a general-purpose short-term bond fund: it sounds like you're interested in things further out along the risk curve than a 0.48% return on a 5-year bond, and thus don't care for the Treasuries. Corporate bonds are generally safer than stocks because, in bankruptcy, all your bondholders have to be paid in full before any equity-holders get a penny. Stocks are much more volatile, since they're essentially worth the value of their profits after paying all their debt, taxes, and other expenses.  As far as stocks are concerned, they're not very good for the short term at all. One of the stabler stock funds would be something like the Vanguard Equity Income Fund, and it cautions: This fund is designed to provide investors with an above-average level   of current income while offering exposure to the stock market. Since   the fund typically invests in companies that are dedicated to   consistently paying dividends, it may have a higher yield than other   Vanguard stock mutual funds. The fund’s emphasis on slower-growing,   higher-yielding companies can also mean that its total return may not   be as strong in a significant bull market. This income-focused fund   may be appropriate for investors who have a long-term investment goal   and a tolerance for stock market volatility. Even the large-cap stable companies can have their value fall dramatically in the short term. Look at its price chart; 2008 was brutal. Avoid stocks if you need to spend your money within a couple of years. Whatever you choose, read the prospectus to understand the risks. If you want to spend all of your money in the next few years, then a CD protects you from the risk of a bear market. however, if your time horizon is longer than 10 years, then the stock market is a better bet, since it is less effected by inflation risk. also, as you point out average stock returns are much higher, ignoring volatility.  On the whole, CD's appeal to people who would otherwise save their money in cash.  generally, it seems these people are simply afraid of stocks and bonds because those securities can lose nominal value as well as real value.  I suspect this is largely because these people don't understand inflation, nor the historical long-term index fund performance. I found a comparison of stock and bond returns.  The relevant portion here is that bonds went up by 10% in 2007 and 20% in 2008 (32% compounded).  Stocks were already recovering in 2009, going up almost 26%.   You don't mention what you were hoping to get from your gold investment, but bonds gave a very good return for those two years. No I get that.  But if you don’t want risk, then buy bonds.  Long term an S&amp;P Index has very low risk.  On the other hand, actively managed funds have fees that take out a ton of the gain that could be had.  I don’t have time to look for the study but I read recently that 97% of actively managed funds were outperformed by S&amp;P Indexes after fees.  Now I don’t know about you but I think the risk of not picking a top 3% fund is probably higher than the safe return of index’s. "Remind him that, over the long-term, investing in safe-only assets may actually be more risky than investing in stocks. Over the long-term, stocks have always outperformed almost every other asset class, and they are a rather inflation-proof investment. Dollars are not ""safe""; due to inflation, currency exchange, etc., they have some volatility just like everything else." "A bond fund will typically own a range of bonds of various durations, in your specific fund: The fund holds high-quality long-term New York municipal bonds with an   average duration of approximately 6–10 years So through this fund you get to own a range of bonds and the fund price will behave similar to you owning the bonds directly.  The fund gives you a little diversification in terms of durations and typically a bit more liquidity.  It also may continuously buy bonds over time so you get some averaging vs. just buying a bond at a given time and holding it to maturity.  This last bit is important, over long durations the bond fund may perform quite differently than owning a bond to maturity due to this ongoing refresh.  Another thing to remember is that you're paying management fees for the fund's management. As with any bond investment, the longer the duration the more sensitive the price is to change in interest rates because when interest rates change the price will track it. (i.e. compare a change of 1% for a one year duration vs. 1% yearly over 10 years) If I'm correct, why would anyone in the U.S. buy a long-term bond fund   in a market like this one, where interest rates are practically   bottomed out? That is the multi-trillion dollar question.  Bond prices today reflect what ""people"" are willing to pay for them.  Those ""people"" include the Federal Reserve which through various programs (QE, Operate Twist etc.) has been forcing the interest rates to where they want to see them.  If no one believed the Fed would be able to keep interest rates where they want them then the prices would be different but given that investors know the Fed has access to an infinite supply of money it becomes a more difficult decision to bet against that.  (aka ""Don't fight the Fed"").  My personal belief is that rates will come up but I haven't been able to translate that belief into making money ;-)  This question is very complex and has to do not only with US policies and economy but with the status of the US currency in the world and the world economy in general.  The other saying that comes to mind in this context is that the market can remain irrational (and it certainly seems to be that) longer than you can remain solvent." If you look at it from the hedging perspective, if you're unsure you're going to need to hedge but want to lock in an option premium price if you do need to do so, I could see this making sense.
