Good question but arguably they don't have to match 5%, they might put these notes in things like a low climate impact fund where conscious investors accept lower returns for the sake of the climate/environment. I'm just thinking out loud though, I'm just an armchair investor, for all I know these notes are paying 10%, although I doubt it.
