The fund tracks the Bloomberg MSCI US Corporate 1-5 Year ESG Focus Index and holds corporate bonds issued by US companies that are financially sound and carry high ESG ratings. It aims to deliver stable interest income while maintaining the low volatility typical of short-term bonds.

It has a conservative investment profile and suits investors who want to preserve portfolio stability while giving weight to social responsibility in their investing.

Launched by iShares in 2017, it is a passively managed (index-tracking) ETF.

The portfolio is built by selecting companies with high ESG scores from the investment-grade corporate bond market. By concentrating on short-term bonds with 1 to 5 years to maturity, the fund manages interest rate risk, and it is adjusted to avoid excessive concentration in any single sector in pursuit of stable performance.

• A combination of short-term bonds from high-quality US companies and ESG criteria
• Cash flow provided through regular monthly dividend payments

Assets under management (AUM) stand at $1.3B, and the expense ratio is 0.12% per year.

Capital is flowing in from institutional and individual investors who want sustainable investing alongside stable income, and the fund's role as a defensive asset stands out when market volatility increases.

Investing in stable, high-quality bonds lets you expect income while protecting principal, but prices can fall in the short term when interest rates are rising.

The VCSH and IGSB shown in the table are representative passive corporate bond ETFs with the same maturity structure, but they do not apply ESG criteria. If you prefer lower fees, SPSB or SCHJ could also be alternatives, and if you want the higher yields of high-yield bonds, you can consider SJNK. If you want broader ESG bond exposure, SUSC is also worth reviewing.
