A new series of exchange-traded funds will make it easier for individual and institutional investors to trade the most current individual benchmark U.S. Treasuries, highlighting the maturing of ETFs in the fixed income space. 

The fixed inome ETFs were launched by North Slope Capital LLC and Genoa Asset Management LLC, which include a two-year and ten-year Treasury ETF.

Treasuries are among the world's most liquid securities but can be cumbersome to trade, especially for investors who must roll them over frequently to maintain the maturity.

The new ETFs, which will eventually include more maturities, as well as options, will make it easier for people managing bond portfolios in a precise way, said Dave Nadig, director of research at ETF Flows.
