This ETF offers exposure to intermediate term government bonds, focusing on Treasuries that mature in three to ten years. As such, interest rate exposure for this product will be moderate; VGLT offers exposure to longer-dated Treasuries while VGSH is an option for those looking to focus on the short end of the maturity curve. VGIT probably doesn't have much appeal as a core holding, since the overlap with broad-based funds such as BND will be significant. But this ETF can be a useful tool for tilting exposure towards Treasuries without a bias towards either end of the maturity spectrum. Like most Vanguard ETFs, VGIT is among the cheapest options available; commission free trading in Vanguard accounts may increase the cost appeal to those keeping an eye on fees. Other options offering similar exposure include IEI, FIVZ, SCHR, and ITE; the effective durations and yields on these products may vary slightly.
