3 short-term bond ETFs to reduce volatility and interest rate risk

Vanguard Short-Term Treasury ETF (VGSH)

Buffett's instructions for his estate's portfolio call for 10% in short-term Treasurys, and it’s easy to see why. Asides from 0–3-month Treasury bills, money market funds, and certificates of deposits, few other assets have the same combination of low interest rate risk, minimal credit risk, and acceptable yields. 

VGSH currently tracks the spliced Bloomberg U.S. Treasury 1-3 Year Index, which calls for a ladder of Treasurys with a dollar-weighted average maturity of 1 to 3 years. Currently, the ETF has an average duration of 1.9 years, and a yield to maturity of 4.6%.

The silver lining of 2022 is that with interest rates rising, bonds are finally paying competitive yields again. I can't remember the last time I saw a short-term Treasury bond ETF having an average yield to maturity of 4.6%. With an expense ratio of 0.04%, VGSH is as cheap as it gets. 

iShares 1-5 Year Investment Grade Corporate Bond ETF (IGSB)

There are generally two ways to squeeze more returns out of your bond ETF. The first way is to increase bond duration, but that exposes you to greater interest rate risk. If you're reading this article, I'm guessing that's not really an acceptable option. 

The other way is to lower credit quality. Treasurys pay less because they're AAA rated. The U.S. government is unlikely to default. On the other hand, investment-grade corporate bonds (BBB or higher) can pay more competitive yields to compensate for their higher credit risk.

A good pick here is IGSB, which holds investment-grade corporate bonds with remaining maturities between one and five years. IGSB has a slightly longer but still short duration of 2.64 years, with an average yield to maturity of 5.37%. The ETF costs a relatively low expense ratio of 0.06%. 

SPDR Bloomberg Short Term High Yield Bond ETF (SJNK)

I'm a fan of taking risk only on the equity side, so my fixed-income holdings are 100% Treasurys. That being said, investors who want to maximize the returns from their bond funds while still mitigating interest rate risk can harvest even higher yields by targeting high-yield bonds.

These bonds have credit ratings below BBB (non-investment grade) and are also referred to as "junk bonds." They tend to have a higher degree of correlation with equities. When the market crashes, junk bonds usually do as well as the creditworthiness of their issuers gets called into question further. 

The upside is a very high yield. For example, SJNK currently has a yield to maturity of 8.98%, despite having a low duration of 2.41 years. Most of its debt is rated BB+, BB, or BB- based on the S&P global rating scale. The ETF is also significantly more pricey with a 0.40% expense ratio.
