What this ETF is trying to do

The iShares USD Green Bond ETF (BGRN) is an exchange-traded fund that invests in "green bonds." These are loans used to fund projects that help the environment.

What the numbers show

As of October 5, 2026, the share price is $45.48. To understand how the fund has performed, we look at two different types of returns: price return (the change in the share price) and total return (which includes the share price change plus the cash distributions paid to investors).

• Year-to-Date (YTD): The price return is -5.12%, while the total return is -1.97%.

• One Year: The price return is -5.40%, while the total return is -1.22%.

• Three Years: The price return is 1.70%, while the total return is 15.25%.

The estimated price from roughly one year ago was $48.07. For example, if you had invested $10,000 based on that estimated price and looked only at the price return (ignoring distributions), your investment would be worth approximately $9,460 today.

Income and distribution explanation

This ETF usually pays out cash to investors every month. Over the last 12 months, it has made 12 payments. The distribution yield is 4.50%.

It is important for beginners to know that a high distribution yield alone can be misleading. While these payments provide cash income, they do not guarantee that the original money you invested (the principal) will stay the same or grow.

NAV erosion explanation

"NAV erosion" happens when the underlying value of a fund's assets declines over time. StockValueFinder uses an erosion-risk score to measure this. BGRN has an erosion score of 75, which is labeled as "mild price erosion." This is a measurement of risk, not a guarantee that the fund's value has collapsed.

Pros

• Consistent Income: The fund has a history of making monthly distributions.

• Long-term Total Return: The three-year total return is positive at 15.25%.

Cons

• Recent Price Decline: Both the year-to-date and one-year price returns are negative.

• Erosion Risk: The fund has a "mild" erosion-risk label.

Beginner takeaway

BGRN provides a way to invest in green bonds and receive monthly cash payments. While the total return over three years has been positive, the share price has declined over the last year. Investors often care about principal stability, meaning they want their initial investment to stay intact even while they collect income.
