Want to find your happy place? Sometimes you have to go your own way.
The consensus advice is to buy individual Treasury Inflation-Protected Securities in a tax-deferred account, most likely a traditional IRA. These bonds pay taxable interest, after all, plus they dole out “phantom income” in the form of taxable inflation accruals.
Before I retired (laid off, technically) in 2016, I had limited investment space in traditional IRAs. But once I was freed from the corporate world, I moved my Vanguard 401k to a self-directed traditional IRA at Vanguard and began looking to restructure my inflation-protected investments. Since 2016, all my TIPS purchases and ladder-building have been in that IRA brokerage account.
But I still had an account at TreasuryDirect, a compilation of many purchases of I Bonds and TIPS for more than 20 years. I’ve been letting the TIPS mature, one by one, and just spending the proceeds. I have maturities still coming every year from 2025 through 2029, plus one in 2041.
Although I know I am not supposed to own TIPS in a taxable account, I view these TIPS holdings fondly. They bring me joy. So, why?
You can’t sell a TIPS at TreasuryDirect.
Actually, you can’t sell any traditional Treasury investment — bill, note, bond, TIPS, FRN — at TreasuryDirect. (Savings bonds are the one exception to this rule.) To sell a TIPS, you need to transfer the security to a bank or brokerage, where it can then be sold. This process, which can be exceedingly tedious and time consuming, is explained here.
However, as a committed buy-and-hold investor, I view this barrier as a plus. I have never sold a TIPS before maturity and plan to never let that happen.
Works for me. But if you are not 100% positive you can hold a Treasury security to maturity, DO NOT invest at TreasuryDirect. Use your brokerage instead, where any Treasury investment can easily be sold.
There is no such thing as ‘market value’ at TreasuryDirect.
Because there is no way to sell a TIPS inside TreasuryDirect — and the fact that TreasuryDirect does not allow tax-deferred accounts where RMDs could come into play — there is no need for the site to track the constantly changing market value of your investment.
Instead, for a TIPS, the only factor TreasuryDirect tracks is:
Par value x inflation index.
And the way TreasuryDirect tracks this amount (which will eventually determine the value at final maturity) is sort of amazing. Although TreasuryDirect publishes TIPS inflation indexes for every day of the year, the site ignores that information on your investment summary page.
Instead, it shows the par value x inflation index as of the date of the last coupon payment. Eventually, this information will be six months old and then finally update. Amazing, isn’t it? An example from last week:
When you buy a TIPS at a brokerage, within a day you will see its market value has changed — rising with falling market real yields and falling with rising real yields. You may see your investment slide “into the red.” But your underlying investment really hasn’t changed. You locked in your real yield to maturity when you made the purchase.
My alternative for tracking these TIPS at TreasuryDirect is to set up a simple Excel spreadsheet to calculate current accrued principal, the only factor that matters to me. I update the inflation index occasionally, with data from this site.
Is it realistic to ignore market value and focus on adjusted principal? In the serene world of TreasuryDirect it makes sense, and it works for me as a buy-and-hold investor. However, many people on Bogleheads would loudly disagree with me.
Obviously, in a tax-deferred account at a brokerage, market value comes into play because of potential required minimum distributions, which are based on market value, not adjusted principal. Plus, you need market information if you decide to sell. Brokerages have a duty to report market value. TreasuryDirect doesn’t.
A taxable brokerage account will also track market value, for the same reason. The TIPS can be sold there and you need that information.
TreasuryDirect is unique in ignoring market value. That being said, I know many investors shun TreasuryDirect (mostly because of account complications or estate considerations) and would never buy a TIPS there.
I Bonds versus TIPS.
For the I Bonds you hold at TreasuryDirect, the accrued principal updates monthly and the site always shows you the accurate current value (minus any potential 3-month interest penalty). Why the difference? Because you can redeem an I Bond on the TreasuryDirect site, and you need to know its current accrued value.
But remember: I Bonds have no secondary market and the accrued principal is the current value. There is no “market value.” And this is the same way TreasuryDirect treats the value of a TIPS — accrued principal as of the last coupon payment. This wipes out the concept of “market value,” which is something I appreciate.
Taxes? Not a problem. They are prepaid.
People don’t like holding TIPS in a taxable account because of the phantom income created by the inflation accruals, which create a tax liability even though they aren’t paid out until the TIPS is sold or matures. With a TIPS in a taxable account, you pay the phantom tax each year. At maturity you owe very little tax — just on a part-year inflation accrual and the final coupon payment.
This comes in handy in retirement. The TIPS matures and the investor gets cash to spend, owes little tax, and gets the benefit of the state income-tax exemption. With a TIPS in a traditional IRA, all taxes are shifted to the date of withdrawal. Once you make a withdrawal the entire amount is taxable at both federal and state levels, where applicable.
But, all things being equal …
If you want to be a serious investor in TIPS, creating a ladder of investments many years into the future, you will want to do this in a tax-deferred brokerage account, not TreasuryDirect. You will need the secondary market to fill the ladder and to take advantage of buying opportunities when you see them.
On TreasuryDirect, you can only buy TIPS at auction. That’s fine, but it will be difficult to build a comprehensive ladder that way. By using a tax-deferred account, you can shift money into TIPS from other investments without facing tax liability for the sales. You could build a multi-year ladder within days when real yields are highly attractive, as they are today.
So, take your choice: Serenity vs. efficiency.
