Germany's tap of the 1.30% October 2027 green Bobl on Tuesday could be its last, given its short residual maturity, The Investment Institute by UniCredit's Francesco Maria Di Bella says in a note. In addition, this bond is rather expensive, with a higher-than-average greenium--or green premium--of two basis points, the fixed income strategist says. The German Finance Agency's auction on Tuesday also includes the 2.60% May 2041 green Bund, which trades at an around 1 basis point greenium, the strategist says. Germany will auction 500 million euros in 2027-dated green Bobl and 1 billion euros in the 2041-dated green Bund. (emese.bartha@wsj.com)
