iShares U.S. Treasury Bond ETF

This ETF provides broad-based exposure to U.S. Treasuries with a number of different maturities. GOVT separates itself from popular funds like AGG by focusing exclusively on Treasuries, unlike the latter ETF which also includes a mixture of agency and corporate bonds as well. GOVT should not be considered as a core holding however, since Treasuries often make up a significant chunk of broad-based fixed income products such as AGG and BND. This ETF holds a basket of debt securities with a remaining maturity of one or more years; as such, investors who are wary of interest rate risk may wish to tilt exposure towards the short end of the maturity curve with a product like SHY. On the other hand, a product like TLT will be more appropriate for investors who are looking to target long-term Treasuries.
