iShares Treasury Floating Rate Bond ETF (TFLO) is an exchange-traded fund that seeks to track the investment results of an index composed of U.S. Treasury floating rate bonds. The ETF invests primarily in U.S. dollar-denominated floating rate public obligations of the U.S. Treasury, with holdings consisting almost entirely of United States Treasury securities that feature weekly resetting coupon rates based on the most recent 90-day T-bill auction rate and quarterly interest payments; it employs a representative sampling technique to replicate the performance of the Bloomberg U.S. Treasury Floating Rate Index. Launched on February 3, 2014, and domiciled in the United States, TFLO is issued by iShares Trust and managed by BlackRock Fund Advisors, with an expense ratio of 0.15%, and trades on the NYSE Arca exchange. The fund operates within the fixed income segment, targeting investors seeking low-risk, short-duration exposure to U.S. Treasuries with minimal interest rate sensitivity, including cash-like alternatives amid rising rate environments, and its geographic focus remains exclusively on U.S. Treasury securities. In recent developments, BlackRock announced portfolio manager changes effective in 2025, adding Jonathan Graves and Marcus Tom to the management team for iShares funds including TFLO; additionally, the firm simplified its Canadian iShares product lineup through reclassifications of advisor class units into common units by late 2024, alongside ongoing institutional adjustments such as holdings changes by investors like ARK & TLK Investments and Creative Planning in 2025.
