TIPS Bonds, How Treasury Inflation-Protected Securities Work

By Pinyo, on January 20, 2009

Treasury Inflation-Protected Securities (TIPS) is a type of Treasury securities that provides protection against inflation and real return. I don’t know if TIPS is the best bond to buy or not, but I am beginning to think that it is after reading articles and books by Larry Swedroe over the years. At the very least, they are great adds to a well-diversified investment portfolio.

How Treasury Inflation-Protected Securities (TIPS) Work

To provide inflation protection, the principal of a TIPS increases with inflation (and decreases with deflation) as measured by the Consumer Price Index (CPI). Like other Treasuries, TIPS pay interest at a fixed rate twice a year. The rate is applied to the adjusted principal, as such, the interest payments rise with inflation and fall with deflation. At the maturity, you receive the adjusted principal or the original principal, whichever is greater — protecting you against both inflation and deflation.

Let’s take a look at an example where you purchased a $1,000 in TIPS at 4.25% interest rate and the CPI rose 3%. First, the principal is adjusted for inflation, so your principal rises from $1,000 to $1,030, and increase of 3% as per the CPI. Then the interest payment would be calculated from the new principal. At the fixed interest rate of 4.25% and adjusted principal of $1,030, the amount of interest would be $43.78.

Key Benefits Of Treasury Inflation-Protected Securities (TIPS)

There are several advantages that make TIPS one of the best bonds to buy, these include:

Inflation Protection – Since TIPS adjust for inflation, they protect investors from the risks of unexpected inflation.
Real Return — Since interest rates are calculated after the principal is adjusted for inflation, investors are guaranteed a fixed rate of return regardless of inflation.
Less Volatility — TIPS are less volatile than traditional Treasury bonds with similar maturity.
Good Diversifier — Due to their low correlation to equities and other fixed-income investments, they reduce the overall volatility and risk of your portfolio.
No Credit Risk — The chance that the government will default on bonds is virtually none — at least in theory.
Tax Exemption — Like other Treasuries, TIPS are exempt from state and local taxes. However, interest payments and inflation adjustments that increase the principal are subject to federal tax in the year that they occur.
Marketable – TIPS can be bought and sold in the secondary securities market. You do not have to hold TIPS to maturity.
No Fee — You can buy TIPS at no fee through TreasuryDirect. However, there is a $45 fee if you wish to sell TIPS before the maturity date.

Where To Find The Latest Rates On Government Bonds

Here are a few sites where you can find the most recent interest rates for Treasury securities:

Conclusion

Of course there are some disadvantages to consider, but overall I think TIPS is a very good fixed-income investment — especially for retirees who are most sensitive to inflation. There are a lot of good information on TIPS. If you are interested in more information, I highly recommend the TreasuryDirect TIPS Research Center. Larry also has a great section on inflation-protected securities in his new book: The Only Guide to Alternative Investments You’ll Ever Need.

Another Perspective -

Was There Ever a Default on U.S. Treasury Debt ?

by Alex J. Pollock

Spectator.Org (21-JAN-2009) – As the bailouts in the current bust inexorably mount, financed in rapidly increasing U.S. government debt, one might wonder whether a default on Treasury debt is imaginable. In the course of history, did the U.S. ever default on its debt?

Well, yes: The United States quite clearly and overtly defaulted on its debt as an expediency in 1933, the first year of Franklin Roosevelt’s presidency. This was an intentional repudiation of its obligations, supported by a resolution of Congress and later upheld by the Supreme Court….

These bonds are a great product for safety and better than most fixed income offers that banks give nowadays.

From what I have been reading, many are recommending corporate bonds since their returns are so much greater than government bonds currently. I think you can get the highest grade bonds w/ interest around 7-10% nowadays. But they are still more risky than the TIPS you recommend. I haven’t put my money in either yet.

I-bonds may be a better option for some because all taxes are deferred until the bond is redeemed.

It seems like a very safe bond to purchase, something you would hold for years. Is this something you recommend? What are the other type of bonds out there and would you recommend others over this?

@Sam — corporate bonds provide better nominal interest rate (i.e., no inflation protection), but you are also taking on greater credit risks and give up some tax advantages. I am not saying it’s better or worse, but there are definitely trade-offs to consider.

@Mr. GoTo — I-Bond also has similar inflation-protection feature, but it has its own limitations as well — specifically, there’s a $5,000 limit per calendar year and it’s non-marketable. But, yes, it could work out better for some individuals.

@Craig — Since I am not a professional, I will abstain from recommending anything. Personally, I think TIPS is one of the best after doing my research on various bonds; although, I am tempted by higher interest corporate bonds.

How are the TIPS redeemed at maturity?

@Rick — It depends on where you purchased your bonds. At maturity, you usually have the option of trading your bonds for cash, or reinvest your money to buy another security. With TIPS you can also sell before it matures. If you go through TreasuryDirect and sell before maturity, there’s a $45 fee.

Great article. I recently bought a TIPS fund and seems to be a pretty simple way to diversify inflation risk (I do believe by 2015, US will have 5%+ inflation and 10%+ interest rates).
