iShares 20+ Year Treasury Bond ETF (3ISE)

Profile

iShares 20+ Year Treasury Bond ETF is an exchange-traded fund that seeks to track the performance of an index composed of U.S. Treasury bonds with remaining maturities of 20 years or greater. It provides targeted exposure to the long end of the U.S. Treasury yield curve, holding a portfolio primarily of long-duration government debt securities issued by the U.S. Treasury. The fund employs a representative sampling technique to replicate the index, focusing on fixed-rate U.S. dollar-denominated bonds, with holdings typically numbering around 45 to 47 securities. Notable characteristics include a high effective duration, making it particularly sensitive to changes in long-term interest rates, and features such as weighted average maturity exceeding 25 years. Managed passively by BlackRock Fund Advisors, iShares 20+ Year Treasury Bond ETF plays a key role in fixed income markets by offering investors a liquid vehicle for pure long-term Treasury exposure, often used for duration management, interest rate hedging, or as a benchmark for government bond performance. Launched in 2002 and domiciled in the United States, it remains a staple for those seeking stability from high-quality sovereign debt in portfolio diversification strategies.
