The new target-date ETF, ticker IBIL, matures in October 2035.
By David Enna, Tipswatch.com
Blackrock’s iShares division last week launched a unique ETF holding just one bond: CUSIP 91282CML2, a 10-year TIPS that matures in January 2035.
The formal name is the “iShares iBonds Oct 2035 Term TIPS ETF,” going by the ticker IBIL. The goal is simple: To track the performance of U.S. Treasury Inflation-Protected Securities maturing in 2035. Later this year IBIL will add a second TIPS, to be issued in July, and then add two more 5-year TIPS to be issued in April and October 2030.
In 2035, these TIPS will mature and iShares will begin moving proceeds to cash. After October 15, iShares will dissolve the fund and return all proceeds to investors. You can download the prospectus here.
As I have noted before, I’m not a fan of Blackrock using the term iBonds in the fund name, since this can easily cause confusion with U.S. Series I Savings Bonds, usually called I Bonds. But ignoring that fault, IBIL joins a collection of defined-maturity, single-year TIPS funds, which began maturing in October 2024 and now run through 2035 with the addition of IBIL.
These are useful ETFs, I think, especially for an investor looking to quickly build a diversified TIPS ladder out to 2035. These funds should closely track the performance of the underlying TIPS. Here is a comparison of data for each ETF, along with Vanguard’s Short-Terms TIPS fund for comparison:
The expense ratios for the iShares ETFs are only 0.10%, higher than VTIP’s 0.03% but quite good for such small funds.
Analysis
These funds are designed to be held to maturity and the asset value will rise and fall with market trends through maturity, just like any other bond fund.
Because the expense ratio is just 0.10%, I really have no problem with using these funds as an alternative to buying individual TIPS. You could quickly build a ladder through 2035 in 15 to 30 minutes, assuming the small daily volume doesn’t create issues.
However, the limited span of maturities means these ETFs aren’t the total solution for building an inflation-protected ladder of investments to cover 20 to 30 years.
Is there a required minimum investment?
No. The minimum investment would be the cost of one share (around $25.18 for IBIL on Friday afternoon) plus any possible brokerage commission. There are no limits on redemptions. iShares notes there can be a bid/ask spread on purchases and sales. That seems especially likely for an ETF that trades at such a low volume. The iShares prospectus notes:
When the Fund’s size is small, the Fund may experience low trading
volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange.
Traders in individual TIPS face these same bid-ask issues and at times can have trouble buying or selling TIPS in small numbers. This new ETF resolves the small-lot issue, at least. You can buy as little as one share.
Morningstar data indicate the spreads can be fairly small, such as about 0.12% for IBIK and 0.38% for IBIJ. But that compares to 0.06% for the highly-traded VTIP.
The small daily trading volumes could also be a roadblock to a large purchase. For example, if you wanted to buy $40,000 of IBII, maturing in 2032, you would buying about 1,540 shares, very close to the daily trading volume of 1,632. You might have to spread purchases over several days.
Income and inflation accrual distributions
One of the advantages of owning a TIPS to maturity is that inflation accruals continue to build over time, increasing the amount of principal and also increasing the semi-annual coupon payment as the principal increases. An individual TIPS gets the benefit of compounding, even though the coupon is distributed twice a year.
But one of the disadvantages of a TIPS is that if held in a taxable account, those inflation accruals are subject to “phantom” federal income taxes in the current year, even though they are not paid out. Plus, if your account is at TreasuryDirect, you will face the “dreaded 1099-OID,” the cryptic form reporting your taxable accruals.
The ETF plus. These defined-maturity ETFs “fix” the OID issue because inflation accruals will be paid out in the current year, along with the coupon interest. (This is the same way traditional TIPS funds work). That distribution makes these iShares TIPS ETFs more attractive for holding in a taxable account, because it eliminates the phantom income problem.
I assume this also means your broker will provide a single 1099-DIV tax form covering both coupon payments and inflation accruals.
The ETF minus. Distributing the inflation accruals in the current year means that at maturity you will be receiving only the original par value and final coupon payment, since all the inflation accruals would have been distributed.
In essence, this means if you buy IBIL at around $25 a share this week, in 2035 you are going to get back about $25 at maturity, but you will have earned inflation accruals and coupon payments along the way.
To get the full benefits of compounding and true inflation protection you would need to reinvest all inflation-accrual distributions back into these TIPS ETFs or another similar product. That could be a problem because of the very low volume. For example, Vanguard says this on reinvestments in general: “A security’s distributions will not be reinvested if the security has a low average daily trading volume.”
I have gotten feedback from readers saying they have been able to reinvest the dividends in these low-volume funds. Beyond the cost of any bid-ask spread, that is great news. If anyone has further experience with buying these funds and/or reinvesting the dividends, please provide the information in the comments section.
Final thoughts
I won’t be investing in this new ETF, IBIL, because I have already purchased CUSIP 91282CML2 as part of my TIPS ladder, filling the 2035 rung. But I can see the appeal for investors looking for a simpler way to invest in TIPS, especially in a taxable account.
The expense ratio of 0.10% is very good, especially if you can make your trades commission-free. But I do warn against using these ETFs in an assets-under-management account, which could wipe out 1% or more of your annual earnings. And in fact, I suspect these ETFs may have been designed for AUM financial advisers who really don’t understand TIPS (a lot of them don’t).
One other issue is the fact that these funds don’t offer true inflation protection over the long term, since they pay out the inflation accruals in the current year. That is great for people seeking cash flow. But an investor seeking inflation protection would need to figure out a way to reinvest distributions.
In summary, these target-maturity TIPS are good investment for cash flow. Individual TIPS are a better investment for inflation protection over the long term.
