During the week of February 22, 2016, the U.S. Treasury yield curve steepened overall as investor expectations of future interest rate rises increased. The yield curve fluctuated between steepening and flattening on different days due to factors like weakening currencies, global economic uncertainty, and U.S. Treasury auctions. By week's end, positive U.S. economic data reduced recession fears and caused investors to sell Treasuries, steepening the yield curve further.
