0509 GMT - Norway's upcoming 20-year bond syndication is expected to be dominated by domestic investors, Danske Bank's Jens Peter Sorensen says in a note. Norway is expected to issue 10 billion Norwegian kronor in the new bond which has a maturity date of September 2046, the chief analyst says. The new bond will lengthen the Norwegian government bond curve by four years, as the currently longest-dated bond has its expiry date in 2042.
