0516 GMT - Norges Bank's decision to include the April 2028-dated government bond alongside the May 2039-dated bond in Wednesday's auction isn't surprising, given demand focusing on shorter maturities and the long end of the curve, SEB's Erica Dalsto says in a note. Meanwhile, "the mid-part of the curve remains offered," the chief Norway strategist says. Against this backdrop, the 2028-dated bond is a "natural addition" to the auction, she says. Norges Bank will offer a combined 3 billion Norwegian kroner in the two bonds. Following this auction, Norway will have issued 78 billion kroner in bonds year to date, approaching the annual supply target of 100 billion kroner to 110 billion kroner, she says.
