iShares 10+ Year Investment Grade Corporate Bond ETF

iShares 10+ Year Investment Grade Corporate Bond ETF (IGLB) tracks the ICE BofA 10+ Year US Corporate Index. That index holds bonds that mature in ten years or more, from companies rated investment grade (BBB or better). The fund's 0.04% expense ratio is well below the 0.15% average of similar funds. Its average maturity was 22.1 years as of August 31, 2026. That makes its price react more to interest-rate moves than broader corporate bond funds.

• Over the year to Oct 27, 2026, IGLB returned -5.4%, 8th of 8 among similar funds.
• Its 5-year annualized return was -3.2% and its 10-year +1.7%.
• In the 2020 COVID crash it fell 27.7% and regained its old high 3.7 months after the low.
• Its worst full calendar year was 2022 (-25.4%); its best was 2019 (+23.2%).
• The deepest fall in its price history was 34.1% (Sep 22, 2021 to Oct 24, 2022), not yet recovered.

As of Aug 31, 2026, the fund held 3,813 securities; the ten largest made up 1.93% of assets, and 13.79% sat in cash and money-market holdings.

The bonds mature in 22.1 years on average (weighted by size), with an average coupon of 4.91%.

• Over the three months to Aug 31, 2026, investors added a net $410.7M (creations minus redemptions, per the N-PORT report).
• Monthly total returns reported for that quarter: +0.23%, -3.84%, +0.77%.

BlackRock runs IGLB to track an index built by ICE Data Indices, an outside provider. To get into the index, a bond must be issued in US dollars and pay a fixed rate. It also needs at least $250 million outstanding, ten or more years left to maturity, and an average investment-grade rating from Fitch, Moody's and S&P. Bonds in default, bonds linked to stocks and municipal bonds are left out. As of February 28, 2026, the index held 3,859 issues, and a large share came from financial companies.

Each bond's weight depends on its market value, so companies with more debt get bigger weights. The index is updated on the last calendar day of each month. Bonds leave as they age below ten years to maturity. The fund doesn't buy every bond. It uses "representative sampling": it holds a sample picked to match the index's duration (how much prices react to rate changes), credit quality, yield and sector mix. At least 80% of assets must be in index bonds. Up to 10% can go into futures, options, swaps or other bonds.

As of August 31, 2026, the fund had 3,815 positions, and its ten largest made up just 1.93% of assets. Turnover was 7%. The fund may lend out up to one-third of its assets. It never moves into cash to protect itself when markets fall.

• IGLB charges 0.04% a year, versus an average of 0.15% for the similar funds below (2nd of 8, cheapest first).
• Using the prospectus's standard example, $10,000 invested would cost about $4 in the first year and $51 over 10 years (assuming a 5% annual return).

IGLB pays monthly income from investment-grade company bonds at a very low cost, but its long maturities make its price swing much more than most bond funds.

IGLB pays income every month. Its trailing 12-month yield was 5.58% as of October 27, 2026. Costs are low: under the SEC's standard example, $10,000 invested would pay about $51 in fees over ten years. The trade-off is price risk. The fund launched in December 2009, so it has no record from the 2008 crisis. In March 2020 it fell 27.7% in under two weeks, then recovered by July 2020. It lost 25.73% in 2022 as interest rates rose. Its deepest drop was 34.1%, from September 2021 to October 2022, and it had not recovered as of October 27, 2026. The monthly income kept coming in those years, but someone forced to sell shares during a slump would have locked in losses. Past results don't predict the future, and a plan should look at the whole portfolio, not one fund.
