At the end of June, there was $1.2 trillion in U.S.-based ETFs. There was $564.1 billion in U.S. equity ETFs, $246.5 billion in international stock funds and $222.1 billion in the fixed-income category.
There are fixed-income ETFs tracking U.S. Treasuries, corporate bonds, muni bonds and other sectors.
The largest bond ETFs include iShares Barclays TIPS (NYSEArca: TIP), iShares iBoxx Investment Grade Corporate Bond (NYSEArca: LQD) and Vanguard Total Bond Market (NYSEArca: BND).
During the first half of 2012, global fixed-income ETFs accounted for 40% of inflows, according to BlackRock.
“As fixed income ETFs continue to be more fully embraced by individuals, advisors and financial institutions, they will solidify their standing as an essential fixed income capital market instrument, in a truly evolutionary step for the market,” said Matthew Tucker, head of iShares fixed income investment strategy at BlackRock.
