It tracks the Bloomberg US Treasury 10 Year Target Duration Index and keeps the portfolio's average duration at roughly 10 years. It manages the target duration on an ongoing basis by selling bonds as they approach maturity and buying new Treasuries.

It suits investors who want to turn interest rate changes at the 10-year point of the US Treasury yield curve into a source of returns, as well as those who need precise duration management, such as for liability matching.

It is a passively managed (index-tracking) ETF launched by Bondbloxx in 2022.

The fund pursues a strategy of fixing its exposure to a specific point on the yield curve (10 years). Unlike typical maturity-range ETFs, the key is that it minimizes fluctuations in duration, keeping interest rate sensitivity at a predictable level.

• Pinpoint exposure to the 10-year segment
• Efficient bond management with a low management fee

Assets under management (AUM) stand at $1.4B, and the expense ratio is 0.08% per year.

Its interest rate sensitivity is higher than that of GOVT, which invests across the entire Treasury curve, and its return profile is entirely different from ultra-short bond ETFs such as SHV and GBIL.

Price volatility has been significant, depending on the direction of long-term US interest rates and the inflation outlook. In particular, demand for 10-year Treasuries tends to concentrate when the peak-rate view and concerns about an economic slowdown come to the fore.

Institutional investors pursuing yield curve strategies, along with capital seeking both stable interest income and capital gains, have been flowing in. Moves are also being observed by investors who want to get ahead of the price gains that long-term bonds enjoy when rates fall.

Precise duration management can maximize the benefit during periods of falling rates, but the risk of price declines when rates rise is also large.

GOVT, shown in the table, is a broad alternative covering the entire Treasury curve, while SHV and GBIL are ultra-short products that minimize interest rate risk. Standard ETFs in the 7 to 10 year range, such as IEF, VGIT, and UST, can also serve as comparisons. For a longer investment horizon, the 7-year target XSVN and the 20-year target XTWY are also worth considering.

These are the factors to review before investing in XTEN. Decisions should take into account both the characteristics of a target duration strategy and the current macroeconomic environment.

A 10-year duration means that price changes in response to interest rate moves are not small. Be aware that losses of principal can deepen during a rate-hiking phase.

This product suits asset allocators who want precise investment exposure to the 10-year segment of US Treasuries. It is a useful tool for adjusting a portfolio's duration and capturing opportunities when rates fall.
