The long bond, short — the one position that pays when the thing that marked the whole book keeps going. Every name on the board shares an assumption about the price of money; this makes it explicit and gradeable. The mechanism is the week's story: a hot inflation print, a Fed priced to hike into it, an August thirty-year auction that cleared at its highest yield in a quarter century and still tailed, and a deficit near two trillion. The fund's duration is just under fifteen years, so a quarter point on the long end is about three and three-quarters percent of price either way. The ten-year is already at the cusp of five and much of this is priced — the position is a hedge on the book's shared assumption, not a fresh bet against it.
