Ask Stacy: Why Is My Bond Fund Losing Money?

There’s no investment safer than U.S. Treasuries. But here’s something odd: You can lose money by investing in them. If you own a bond mutual fund, or know someone who does, read this.

Better Investing

The safest investment in the world is U.S. Treasury bonds. The reason is simple: Uncle Sam can’t default on his obligations, because he can print the money to pay them.

Ironically, however, you can rack up serious losses in all kinds of bonds, including the world’s safest. Which brings us to this week’s reader question.

I’ve put a bunch of money into TIPS in the last two years in my 401(k). I got a statement from Vanguard that shows I’ve lost $6,000 in value in the last year. Or at least I think that’s what the statement means. Will I recover the value? How does that happen? I don’t get it.

This reader owns a fund that invests in a type of U.S. Treasury bond known as TIPS, something I’ll explain shortly. But if you own any kind of bond mutual fund, you really need to understand how they work and the potential for risk.

We’ll start with a quick explanation of TIPS, then move on to other types of bonds.

How do TIPS work?

TIPS is short for Treasury Inflation-Protected Securities. The idea behind them is simple: When you invest in TIPS, not only does Uncle Sam guarantee you’ll get your money back, he offers protection against inflation.

From the Treasury’s TIPS page:

Treasury Inflation-Protected Securities, or TIPS, provide protection against inflation. The principal of a TIPS increases with inflation and decreases with deflation, as measured by the Consumer Price Index. When a TIPS matures, you are paid the adjusted principal or original principal, whichever is greater.

And TIPS should be safe. From Investopedia:

TIPS are considered an extremely low-risk investment since they are backed by the U.S. government and since their par value rises with inflation, as measured by the Consumer Price Index, while their interest rate remains fixed.

The bottom line: If you buy TIPS at par (face) value, you shouldn’t be able to lose money. So how could our reader have lost value? To understand that, you need to understand the following.

How bonds work

While it may seem as if there are hundreds of different investments, the vast majority fall into two categories:

  • Loaner: You lend money to someone and they promise to pay it back at some future date, along with some interest. Loaner investments include certificates of deposit and all types of bonds.
  • Owner: You own part of a company, typically in the form of stock. There’s no set interest rate, no maturity date and no guarantee you’ll get your money back.

While it may seem as if there are many different types of risk in investing, there are basically only two:

  • Default risk: The company or issuer of the security goes bankrupt.
  • Market risk: The risk that the market value of the security declines.

U.S. Treasury bonds are loaner investments. As I said above, they have virtually no default risk, because the government can print money. But from the time they’re issued until the day they mature, which could be as long as 30 years, Treasury bonds fluctuate in value. They have market risk.

And sure enough, the Vanguard TIPS mutual fund, as I write this, has dropped by nearly 2 percent in the last year.

What makes bonds go up and down in value?

If you’re willing to wait until U.S. Treasury bonds mature, you’ll always get the face amount. But as I said, between now and then, prices can change. To understand how, imagine a seesaw.

On one end of the seesaw are bond prices. On the other are interest rates. If interest rates rise, bond prices fall. If rates fall, bond prices rise.

To put it technically, bond prices are inversely correlated to interest rates.

Why is this? Well, imagine last year I put $1,000 into a 10-year Treasury bond with an interest rate of 1 percent. But today interest rates have risen and now identical 10-year bonds are being issued with a rate of 2 percent. Since anyone would rather earn 2 percent than 1 percent, if I wanted to sell my bond today, I’d have to sell it at a discount. Interest rates went up and my bond’s value went down.

Remember, it’s still going to be worth $1,000 when it matures. But today? Nope. Something else to know: The longer it is until the bond matures, the more it will drop in value if rates rise.

Now let’s go from classroom to the real world. I came across an old quote in Kiplinger from one of the managers of Karen’s TIPS fund. It’s perfect to put this lesson in perspective:

When rates rise, TIPS prices will fall. … If rates rise 1 percentage point, the typical TIPS mutual fund will lose about 6 percent of its value. “Investors need to understand that they are buying inherently volatile vehicles,” says Gemma Wright-Casparius, co-manager of Vanguard Inflation-Protected Securities.

If the value of my fund drops, will it come back?

Karen is rightfully concerned that her TIPS fund has decreased in value by $6,000. But shouldn’t that decline be temporary? After all, I just explained that while bonds may fluctuate in value, they should mature at face value. That means any losses showing on her statement between now and then are only temporary.

Or are they?

    This is why I sold my bond funds and started buying bonds directly. Bond funds change in value on based on the current mood of the market while individual bonds are a fixed contract with a known return.

    Good answer, and its true.
    So what I have been wondering since the New Year is why then are long term bond funds doing so well when interest rates are due to rise?
    The Vanguard long term Treasury fund has a total return of over 10.5 percent year to date, but did terrible last year. So what happened?
    The wisdom now is to be in shorter term bonds, but long term is making a killing. So what gives?
    Very frustrating. I think the stock market is easier to figure out than the bond market.

  • Ron Sakulin

    …which is why I limit my exposure in the bond market to no more than 10% of my portfolio. I did, at one time, try the Vanguard Short Term Bond Index but realized that the income provided was essentially the same as the Vanguard Index 500 but with limited upside potential and similar risk. Bad decision so I dumped it. Over time, bond fund gains are consumed by inflation. I also ignore rebalancing which appears to increase my tax liability. My strategy has rewarded me well.

    Buying bonds is relatively safe, as long as you can wait them out. Buying bond funds can be very dangerous. If you want to diversify, buy stock index funds, and buy bonds.

    I think that the relatively “minuscule” increases are in fact huge. The percentages are causing people to miss how big this really is. In the example above of Treasuries going from 1% to 2% looks like an increase of 1% but do the math, it is a 100% increase. r0:1% = 0.01; r1:2% = 0.02.
    (r1-r0)/r0: (0.02 – 0.01)/ 0.01 = 0.01/0.01 = 1, which means 100%

    You’re getting double the amount of interest which is 100% not 1%.

    The fed rate was 0.75% now increased by 0.25% to 1%. Just do the math. That again is large, it is a 33% increase, how does that count as minuscule?

    The thing that I don’t understand is that mark to market for the general public is irrelevant. You’re not really losing (or making) money until you sell whether it is bonds or equities, or even commodities. I bought 3 of the Dow in 2006. Then in 2009 the market tanked. Panic arose and people dumped their stocks at losses, some of my 3 went down below half the price I paid. Instead of dumping them, I bought boat loads more of my 3 names in 2009. Now they’re all at least double the highest price I paid for them. Did I lose money in 2009? No, I didn’t sell. Did I make money this year? No. I haven’t sold them yet.
