“Floating rate securities pass on rate rises in the form of higher coupons, and alternatives for investors to manage rising rates have increased. It is critical to distinguish between different types of floating rate debt,” said BlackRock in a note out Thursday.

As a result of the safe and conservative nature of floating rate bonds, investors should not expect high yields. Nevertheless, Treasury money market funds are so starved for yield that anything with an extra basis point or two and the quality and liquidity of a Treasury security will provide an attractive alternative.

“The U.S. Treasury began issuing short-maturity floating rate notes in 2014 to diversify its cash funding needs. These bonds sport two-year fixed maturities and quarterly coupon resets. Short-term debt is not floating rate but can fit the bill by rolling over maturing debts at new yield levels. Indeed, short-duration bonds have posted positive returns even amid rising short-term U.S. rates,” according to BlackRock.
