About BILS
State Street SPDR Bloomberg 3-12 Month T-Bill ETF is a fixed income exchange-traded fund that seeks to track the Bloomberg 3-12 Month U.S. Treasury Bill Index. The fund invests primarily in U.S. Treasury bills with remaining maturities between three and twelve months, giving investors exposure to short-term government debt. Its portfolio is designed to reflect the price and yield performance of this segment of the Treasury market through a sampling approach rather than holding every security in the index. BILS is used by market participants seeking a liquid, low-duration vehicle within the U.S. Treasury universe, with holdings concentrated in investment-grade government securities. The fund is issued by State Street and forms part of its SPDR lineup of fixed income ETFs focused on short-term cash management and government bond exposure.
