0519 GMT - RBC BlueBay Asset Management sees some value in five-year U.S. Treasurys as they have approached 5% yields, says fixed income CIO Mark Dowding in a note. However, RBC BlueBay remains "more circumspect" regarding longer-dated maturities, he says. Ongoing heavy debt issuance volumes from governments and corporates continue to pressure term premia globally and from this point of view, RBC BlueBay is disinclined to extend beyond intermediate maturities.
