Divided, not subtracted. Taking inflation off a rate understates what is left, because the shillings you end the year with are themselves worth less — at these levels the difference is small but it is not nothing, and it always flatters. Only rates observed recently enough to still mean something are here; a yield measured eighteen months ago set against this month's inflation is two readings from different worlds.
