Types of Treasury ETFs
Beyond structure, Treasury ETFs differ by the segment of the yield curve they target and the kind of income or protection they offer.
- Short-term Treasury ETFs: Focus on bonds that are maturing within one to three years and offer lower interest rate risk with modest yields.
- Intermediate-term Treasury ETFs: Hold maturities of three to 10 years and balance income potential with moderate interest rate sensitivity.
- Long-term Treasury ETFs: Invest in bonds maturing beyond 10 years and provide higher yield potential with greater price volatility.
- Total Treasury market ETFs: Provide broad exposure across the entire U.S. Treasury yield curve, including short, intermediate, and long maturities.
- STRIPS ETFs: Hold zero-coupon Treasury securities where interest is separated from the principal, producing higher interest rate sensitivity and no periodic income.
- TIPS ETFs: Invest in Treasury Inflation-Protected Securities, which adjust principal based on inflation and help preserve purchasing power.
- Leveraged Treasury ETFs: Use derivatives like index swaps or Treasury futures to amplify daily exposure to Treasury bond prices, increasing both returns and risk.
Factors to consider before investing in Treasury ETFs
When comparing Treasury ETFs, two of the most important metrics to understand are the 30-day SEC yield and duration.
The 30-day SEC yield reflects the ETF's annualized income based on the past 30 days of interest earned by its holdings, after accounting for expenses. In simple terms, it's the most accurate snapshot of what you can expect to earn in yield if current rates hold.
Duration, on the other hand, measures the ETF's sensitivity to interest rate changes. The longer the duration, the more the fund's price will move in the opposite direction of interest rate shifts.
You may also see yield to maturity (YTM) listed, which represents the theoretical total return potential of the ETF's underlying bonds if they were held to maturity.
While it's useful for estimating long-term returns, YTM is less practical for most Treasury bond ETFs since the holdings are frequently rolled over as bonds mature and new ones are added.
How to invest in Treasury bond ETFs
Start by identifying why you want to invest in Treasury bond ETFs. For most investors, the goal is to reduce overall equity risk. Income tends to be a secondary concern, as Treasury bond yields are lower than corporate bond yields due to their minimal credit risk.
Once your objective is clear, decide which part of the yield curve you want to target: short, intermediate, or long-term maturities.
Short-term Treasuries are ideal for capital preservation and low volatility. Long-term Treasuries can be powerful hedges during recessions or rate cuts, but they carry more risk if interest rates rise. Most investors opt for intermediate-term exposure or a broad basket that averages to an intermediate duration.
Finally, picking the right Treasury bond ETF often comes down to cost. Most of these ETFs are highly liquid and offer similar yields and durations, so the lower the expense ratio, the better your long-term returns will be.
